When a VLAN filter list is specified, only those VLANs in the list are monitored on trunk ports or on voice VLAN access ports. Select Load balancers in the search . Nevertheless, the connection can be dangerous if you connect the destination port to other networking equipment that creates a loop in the network. A destination port receives copies of sent and received traffic for all monitored source ports. With use of the SPAN feature, a packet must be sent to two different ports, as in the example in the Architecture Overview section. The Catalyst 3550, 3560, and 3750 Switches can support up to two SPAN sessions at a time and can monitor source ports as well as VLANs. Configure the setting for WAN 1 with IP address 10.12.136.180 on a physical . The physical port cannot be part of a trunk. The hub does not perform any error checks. Navigate to the port forwarding section of your router. Note: From Cisco IOS Software Release 12.2(33)SXH and later, PortChannel interface can be a destination port. Note: Even when the inpkts option prevents the loop, the configuration that this section shows can cause some problems in the network. If ports are added to or removed from the source VLANs, the traffic on the source VLAN received by those ports is added to or removed from the sources thaat are monitored. You must create this VLAN. Using remote SPAN (RSPAN) or encapsulated RSPAN (ERSPAN) allows you to send the collected packets across layer-2 domains for analysis. If you select none, the port only receives traffic. 6. How to troubleshoot crashes detected by Google Play Store for Flutter app, Cupertino DateTime picker interfering with scroll behaviour. 3. The workaround for this issue is to use the regular SPAN. To configure SPAN through the CLI . This time, use Fa0/4 as a destination SPAN port: Issue a show running command, or use the show port monitor command in order to check the configuration: Note: The Catalyst 2900XL and 3500XL do not support SPAN in the Rx direction only (Rx SPAN or ingress SPAN) or in the Tx direction only (Tx SPAN or egress SPAN). However, the Catalyst 2950 cannot monitor the VLANs. A reflector port receives copies of sent and received traffic for all monitored source ports. The configuration of a non-existent VLAN as an ingress VLAN is not allowed. Put the TCP and UDP ports of the Fortinet Fortigate server in the boxes in your router. Aha, nevermind. the FortiGate console providing a true single-pane-of-glass management for ease-of-use and lower TCO Switch Controller Integrated switch controller for Fortinet access switches with no additional license or component fees Simplifies NAC deployment Expands security to the access level to stop threats and protect terminals from one another I'm dealing with a FortiGate 100D for the first time, and am scratching my head as there doesn't seem to be an easy way to mirror ports in the switch; which is really a facility that I presumed it would provide. RSPAN allows you to monitor source ports that are spread all over a switched network, not only locally on a switch with SPAN. You can specify several VLANs with this filter option. Ackermann Function without Recursion or Stack. A destination port has these characteristics: A destination port must reside on the same switch as the source port (for a local SPAN session). By focusing on traffic to and from specified ports and traffic to a specified MAC or IPaddress, ERSPAN reduces the amount of traffic being mirrored. While the data is copied into shared memory, the control path determines where to switch the packet. On the top, all the satellites are interconnected via a high-speed notify ring that is dedicated to signaling traffic. Select the SPAN checkbox, then select a source port from which you want traffic mirrored. 6. Note: This filter option is only supported on Catalyst 4500/4000 and Catalyst 6500/6000 Switches. fortigate interface configuration cli fortigate interface configuration cli. communities including Stack Overflow, the largest, most trusted online community for developers learn, share their knowledge, and build their careers. Therefore, the sniffer does not see this traffic: In this configuration, the sniffer only captures traffic that is flooded to all ports, such as: Multicast traffic with CGMP or Internet Group Management Protocol (IGMP) snooping disabled. Acceleration without force in rotational motion? Currently, the ERSPAN feature is supported in: Supervisor 720 with PFC3B or PFC3BXL running Cisco IOS Software Release 12.2(18)SXE or later, Supervisor 720 with PFC3A that has hardware version 3.2 or later and running Cisco IOS Software Release 12.2(18)SXE or later. Incoming traffic is accepted and switched, with untagged packets classified into VLAN 7. The creation of a bridging loop typically occurs when the administrator tries to fake the RSPAN feature. A reflector port receives copies of sent and received traffic for all monitored source ports. RSPAN does not work when the RSPAN source session and the RSPAN destination session are on the same switch. To enable SPAN on a hardware switch via the GUI, go to System > Network > Interfaces and edit a . Click Create New to create a new VDOM. Select the destination port to which the mirrored traffic is sent. The reflector port forwards only the traffic from the RSPAN source session with which it is affiliated. An ingress or egress port cannot be mirrored to more than one destination port. Can You Have Several SPAN Sessions Run at the Same Time? You can see that RSPAN packets are flooded into the RSPAN VLAN. Create a new inbound port rule for TCP 8443. The network interface is listed, and the inbound port rules are shown. Each time that you issue a new set span command, the previous configuration is invalidated. If multicast streams sourced behind the FWSM must be replicated at Layer 3 to multiple line cards, the automatic session copies the traffic to the supervisor through a fabric channel. S1 and S2 are two Catalyst 6500/6000 Switches. Select the SPAN check box, then select a source port from which traffic will be mirrored. Packets only enter the RSPAN VLAN in switches that are configured as RSPAN source. Destination (SPAN) port A port that monitors source ports, usually where a network analyzer is connected. In the menu on the left, select Networking. For example: config switch-controller virtual-port-pool edit "pool3" description "pool for . Note: The result is exactly the same as if you implement SPAN individually on all the ports that belong to the VLANs that the command specifies. Create a subscription. S2 and S3 are intermediate switches. By default, the system may have a hardware switch interface called a LAN. Ingress trafficTraffic that enters the switch. Using remote SPAN (RSPAN) or encapsulated RSPAN (ERSPAN) allows you to send the collected packets across layer-2 domains for analysis If the bandwidth of the reflector port is not sufficient for the traffic volume from the corresponding source ports, the excess packets are dropped. Egress trafficTraffic that leaves the switch. I will look into the ERSPAN to see what that is about. I could do it with a passive network tap, of course; but it seems really strange to me that the 100D doesn't seem to expose an easy way to do this. However, port snooping is not supported on these switches. When a packet goes through a switch, these events occur: The packet is stored in at least one buffer. Visit Stack Exchange Tour Start here for quick overview the site Help Center Detailed answers. Operational sourceA list of ports that are effectively monitored. Therefore, this feature is relatively easy to understand. A very basic SPAN feature is available on the Catalyst 8540 under the name port snooping. In the search box at the top of the portal, enter Load balancer. Its not particularly elegant, but it works so I though Id knock up a quick blog post as it might help someone else trying to get this working. I added a member to the FortiLink interface and setup port spanning to the analyzer, but it is not receiving any traffic. Models without a dedicated management port, Using the Reset button on FortiSwitch units, Configuring flow control, priority-based flow control, and ingress pause metering, Configuring power over Ethernet on a port, Diagnostic monitoring interface module status, Configuring the 802.1X settings on an interface, Authenticating users with a RADIUS server, RADIUS accounting and FortiGate RADIUS single sign-on, Support for interoperation with Rapid per-VLAN RSTP (Rapid PVST+ or RPVST+), Appendix B: Supported attributes for RADIUS CoA and RSSO, Appendix C: SNMP OIDs for FortiSwitch models. Give the new interface a name (and alias if required) > Interface Type should be VLAN > Select the parent physical interface > Add the VLAN ID (Tag) and specify an IP address of the interface. If you check for unused sessions with the show monitor command, session 1 is used: When a firewall blade is in the Catalyst 6500 chassis, this session is automatically installed for the support of hardware multicast replication because an FWSM cannot replicate multicast streams. The packet is eventually retransmitted on the egress port. The default is enable. You can also create a new hardware switch interface. In this example, we monitor traffic from VLAN 5 that is spread across two switches: On the remote switch, use this configuration: In the previous example a port was configured as a destination port for both local SPAN and the RSPAN to monitor traffic for the same VLAN that resides in two switches. The port GE0/8 is where the user device is connected. All active ports in the source VLAN are included as source ports and can be monitored in either or both directions. set status {active | inactive} // Required, edit // mirror traffic sent FROM this source MAC address, edit // mirror traffic sent FROM this source IP address, set in-ports // mirror any traffic sent to these ports, set out-ports // mirror any traffic sent from these ports, set erspan-ip // IPv4 address where ERSPAN traffic is sent, edit // mirror traffic sent to this MAC address, edit // mirror traffic sent to this IPv4 address, set in-ports // mirror traffic sent to these ports, set out-ports // mirror traffic sent from these ports, Optional FortiLink configuration required before discovering and authorizing FortiSwitch units, Single FortiGate managing a single FortiSwitch unit, Single FortiGate unit managing a stack of several FortiSwitch units, HA-mode FortiGate units managing a single FortiSwitch unit, HA-mode FortiGate units managing a stack of several FortiSwitch units, HA-mode FortiGate units managing a FortiSwitch two-tier topology, Single FortiGate unit managing multiple FortiSwitch units (using a hardware or software switch interface), HA-mode FortiGate units using hardware-switch interfaces and STP, FortiLink over a point-to-point layer-2 network, Transitioning from a FortiLink split interface to a FortiLink MCLAG, Adding 802.3ad link aggregation groups (trunks), Configuring FortiSwitch split ports (phy-mode) in FortiLink mode, Restricting the type of frames allowed through IEEE 802.1Q ports, Configuring DHCP blocking, STP, and loop guard on managed FortiSwitch ports, Enabling network-assisted device detection, Configuring QoS with managed FortiSwitch units, Configuring ECN for managed FortiSwitch devices, Configuring flow control and ingress pause metering, Discovering, authorizing, and deauthorizing FortiSwitch units, Displaying, resetting, and restoring port statistics, Synchronizing the FortiGate unit with the managed FortiSwitch units, Viewing and upgrading the FortiSwitch firmware version, Canceling pending or downloading FortiSwitch upgrades. You cannot convert an existing VLAN into an RSPAN VLAN. You can use the no monitor session service module command in order to disable the SPAN reflector. Click Add to display the configuration editor. Press J to jump to the feed. Curious if this really doesn't work on a 60E? Some of their ports are configured to be destination for an RSPAN session. View with Adobe Reader on a variety of devices, View in various apps on iPhone, iPad, Android, Sony Reader, or Windows Phone, View on Kindle device or Kindle app on multiple devices, Catalyst Switches That Support SPAN, RSPAN, and ERSPAN, SPAN on the Catalyst 2900XL/3500XL Switches, Features that are Available and Restrictions, Sample Configuration on the Catalyst 2900XL/3500XL, SPAN on the Catalyst 2948G-L3 and 4908G-L3, SPAN on the Catalyst 2900, 4500/4000, 5500/5000, and 6500/6000 Series Switches That Run CatOS, PSPAN, VSPAN: Monitor Some Ports or an Entire VLAN, Monitor a Subset of VLANs That Belong to a Trunk, Setup of the ISL Trunk Between the Two Switches S1 and S2, Configuration of Port 5/2 of S2 as an RSPAN Destination Port, Configuration of an RSPAN Source Port on S1, Other Configurations That Are Possible with the set rspan Command, SPAN on the Catalyst 2940, 2950, 2955, 2960, 2970, 3550, 3560, 3560-E, 3750 and 3750-E Series Switches, SPAN on the Catalyst 4500/4000 and Catalyst 6500/6000 Series Switches That Run Cisco IOS System Software, Performance Impact of SPAN on the Different Catalyst Platforms, Frequently Asked Questions and Common Problems, Connectivity Issues Because of SPAN Misconfiguration. Centering layers in OpenLayers v4 after layer loading. I found it in the FortiOS CLI reference, under switch-interface > span/span-dest-port/span-direction/span-source-port. The information in this document was created from the devices in a specific lab environment. For Windows, download from http://www.wireshark.org NOTE: You can use virtual wire ports as ingress and egress mirror sources. This diagram illustrates the structure of an RSPAN session: In this example, you configure RSPAN to monitor traffic that host A sends. Why does awk -F work for most letters, but not for the letter "t"? Configuring network interfaces. Whether one or several ports eventually transmit the packet has absolutely no influence on the switch operation. I'm dealing with a FortiGate 100D for the first time, and am scratching my head as there doesn't seem to be an easy way to mirror ports in the switch; which is really a facility that I presumed it would provide. But make sure the RSPAN VLAN is present in the databases of these VTP domains. The switching functionality is enabled on the dst interface when mirroring. The solution I came up with is as follows: 1. The 100E is running v6.0.4. To enable SPAN on a hardware switch via the GUI, go to System > Network > Interfaces and edit a hardware switch interface. Questions or comments on this page's content? Next step is to get the sniffer VM setup. Required fields are marked *. Solution 2. Use a list of one or more VLANs as a source, instead of a list of ports: With this configuration, every packet that enters or leaves VLAN 2 or 3 is duplicated to port 6/2. You cannot use filter VLANs in the same session with VLAN sources. To enable SPAN on a hardware switch via the GUI, go to System > Network > Interfaces and edit . The destination port can then be located anywhere in this RSPAN VLAN. The traffic is then placed on the RSPAN VLAN and flooded to any trunk ports that carry the RSPAN VLAN. By default the system may have a hardware switch interface called LAN. I found it in the FortiOS CLI reference, under switch-interface > span/span-dest-port/span-direction/span-source-port. In order to make this determination, a hash value is computed from this information: Class of service (CoS) (either IEEE 802.1p tag or port default). Issue the monitor session session_number destination interface interface_id encapsulation dot1q command in order to enable encapsulation of the packets at the destination port. On the Catalyst 4500/4000, 5500/5000, and 6500/6000 Switches with CatOS 5.1 and later, you can have several concurrent SPAN sessions. Similarly, when you see a corrupted packet on your sniffer in the scenario in this section, you know that the errors were generated at step 3, on the egress segment. The knowledge of this index allows the line card to decide individually whether it should flush or transmit the packet as the line card receives the packet in its buffers. Configure a SPAN session using the spare vmnic's switchport as the SPAN target 9. Start the sniffer and you should be capturing traffic from the physical port, 1. Refer to the current Catalyst 8540 documentation for additional information. Select to mirror traffic received, traffic sent, or both. Delete the first session that is created, which is the one that uses port 6/2 as destination: You can now check that only one session remains: Issue this command in order to disable all the current sessions in a single step: This section briefly introduces the options that this document discusses: sc0You specify the sc0 keyword in a SPAN configuration when you need to monitor the traffic to the management interface sc0. ERSPAN is by far the easiest way to do this type of thing if its available to you. monitor session 1 destination interface Gi1/0/16 When you configure a SPAN session to monitor the port, the destination interface shows the state down (monitoring), by design. Create a new VM if you dont have one already. The variable snoop_direction is the direction of traffic on the source port or ports that are monitored: receive, transmit, or both. Copyright 2023 Fortinet, Inc. All Rights Reserved. Do EMC test houses typically accept copper foil in EUT? Any port configured as a src-ingress or src-egress port in one mirror cannot be configured as a destination port in another mirror. I'm new to the hardware/FortiOS, though -- so possibly I am simply missing something obvious. Each source port can be configured with a direction (ingress, egress, or both) to monitor. propos de nous; Conditions de prlvements; Services Packets that are received on a destination port then enter the VLAN, as if this port were a normal access port. In ERSPAN mode, traffic is encapsulated in Ethernet, IPv4, and generic routing encapsulation (GRE) headers. Can a SPAN and an RSPAN Session Have the Same ID Within the Same Switch? What does a search warrant actually look like? At the same time, the Encoded Address Recognition Logic (EARL) receives the header of the packet and computes a result index. Caution: This issue is still in the current implementation of the CatOS. Apart from this difference, SPAN and RSPAN really behave in the same way. The SPAN feature is supported on the Catalyst 4500/4000 and Catalyst 6500/6000 Series Switches that run Cisco IOS system software. This term has been used several times during the evolution of the SPAN in order to name additional features. Can an RSPAN Session Work Across WAN or Different Networks? The SPAN feature on a Layer 3 switch is called port snooping. Thats it, you should now be able to see all traffic in and out of the target port on your sniffer. Source ports can be in the same or different VLANs. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. NOTE: ERSPAN is supported on FSR-124D and platforms 2xx and higher. places with wifi near me; science applications international corporation headquarters address; zaxby's blue cheese dressing nutrition This port is called a SPAN port. If no IPaddress is specified, the traffic is not mirrored. The fields include the destination ports. So I needed to create TWO sub interfaces on the FortiGate (on port3). This list of ports can be different from the administrative source. Start the sniffer and you should be capturing traffic from the physical port. Server Fault is a question and answer site for system and network administrators. Issue this command: All incoming packets on port 6/2 are now flooded on the RSPAN VLAN 100 and reach the destination port that is configured on S1 via the trunk. 4. Destination EtherChannels do not support the Port Aggregation Control Protocol (PAgP) or Link Aggregation Control Protocol (LACP) EtherChannel protocols; only the on mode is supported, with all EtherChannel protocol support disabled. The show rspan command gives a summary of the current RSPAN configuration on the switch. But, the potential issue is still present on the Catalyst 2900XL/3500XL Series Switches. 2. Error "% Local Session Limit Has Been Exceeded", Cannot Delete a SPAN Session on the VPN Service Module, with the Error "% Session [Session No:] Used by Service Module". On FortiSwitch models that support RSPAN and ERSPAN, set the trunk or physical port that will act as a mirror. This feature appears in CatOS 5.2 on the Catalyst 4500/4000 and 5500/5000, and in CatOS 5.3 on the Catalyst 6500/6000. The action often occurs because of a typographical error, for example, if the user wants to enable STP. Sorted by: 3. Previously, SPAN was a relatively basic feature on the Cisco Catalyst Series switches. set status active. 24h/24 - 7j/7. You use several command lines in order to configure the source and the destination with RSPAN. The port captures traffic that is software-routed or directed to the MSFC. In this way, you can view the packets. How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? VM FEX might work here too although I dont know if you can span to a veth (never tried it although a Nexus 5K will take the config!). A destination port cannot be a source port. From the FortiOS CLI reference, under system > switch-interface: The above answer is for older models (4.0). Select Enabled to make the mirror active. Choose the source port and select the VLAN you plan to monitor. Always specify the destination port after the SPAN source. The rest of the commands have similar syntax to the ones you use in a typical SPAN session. The other sections of this document describe how you can tune this feature very precisely in order to do more than just monitor a port. Local SPANThe SPAN feature is local when the monitored ports are all located on the same switch as the destination port. Eventually, the set span command allows you to configure a port to monitor local traffic for an entire VLAN. The total number of active sessions depends on your configuration. A destination port cannot be an EtherChannel group. Therefore, when you consider this architecture, the SPAN feature has no impact on the performance. Issue thesnoop command in order to set up port-based traffic mirroring, or snooping. No spaces. To create a virtual domain: In the Device Manager tab, display the device dashboard for the unit you want to configure. The Ingress VLAN allows the PC connected to the Diagnostics port to send packets to the network that uses that VLAN. Save the configuration. 4 x 3 pings = 12 packets and I should also see the replies,so the sniffer should have 24 frames in total in its display buffer. I will send some pings from my Mac to various devices connected to the switch in the garage. For example, you can create PSPAN sessions on the configuration port that you have chosen to be a destination SPAN port. Why Is PNG file with Drop Shadow in Flutter Web App Grainy? Add a port group to the vSwitch call it SPAN Target to make it obvious what it is for When a satellite receives a packet from a port, the packet is split into cells and sent to the switching fabric via one or more channels. Create a virtual port pool (VPP) to contain the ports to be shared: config switch-controller virtual-port-pool edit <VPP_name> description <string> next. Has anyone successfully done this with FortiLink? Click on Port Forwarding. Note: Unlike the 2900XL and 3500XL Series Switches, the Catalyst 2940, 2950, 2955, 2960, 2970, 3550, 3560, 3560-E, 3750, and 3750-E Series Switches support SPAN on source port traffic in the Rx direction only (Rx SPAN or ingress SPAN), in the Tx direction only (Tx SPAN or egress SPAN), or both. My Switch isnt Cisco its HP/Aruba!Then you simply TAG the VLANs required to the uplink see this article. Standard port spanning allows you to mirror one or more physical source ports or VLANs to one or more destination ports, but it does not allow you to set the target to a remote IP Address or a vSwitch. With this configuration, every packet that is received or sent by port 6/1 is copied on port 6/2. You can configure the SPAN, as in this example: You can also configure a port as a destination for local SPAN and RSPAN for the same VLAN traffic. Select the destination port to which the mirrored traffic is sent. Other ports and the management interface are configured in the default VLAN 1. On the Catalyst 2900XL/3500XL Series Switches, the number of destination ports that are available on the switch is the only limit to the number of SPAN sessions. The vlan 1 keyword simply refers to the administrative interface of the switch. VTP negotiation does the rest. The SPAN feature was introduced on switches because of a fundamental difference that switches have with hubs. How to enable Cisco switch port mirroring without rebooting? February 26, 2023 . multicast enable/disable As the name suggests, this option allows you to enable or disable the monitoring of multicast packets. Enter the IP address of your device in your router in the correct box. Multiple ingress or egress ports can be mirrored to the same destination port. All that traffic should be seen by the sniffer. A destination port can participate in only one SPAN session at a time. In the Catalyst 6500 Series, it is important to note that egress SPAN is done on the supervisor. edit <mirror_name>. All SPAN ports are designed to capture both Rx and Tx traffic. Add the rx (receive) or tx (transmit) keyword to the end of the command. RSPAN is not supported on all switches. After this forwarding table is built, the switch forwards traffic that is destined for a MAC address directly to the corresponding port. monitor session 1 source interface Gi1/0/24 With this limitation in mind, I came up with a solution. Can You Configure SPAN on an EtherChannel Port? Currently, a Catalyst 6500/6000 can have up to 24 RSPAN destination ports, for one or several different sessions. How to SPAN a physical port to a Virtual Machine, VMware Fusion Labs Part III Adding Storage, Labs and Simulation on VMware Fusion Part II, Labs and Simulation on VMware Fusion Part I. Here, the mirrored ports are assigned to VLANs 1, 2, and 3. You separately configure ERSPAN source sessions and destination sessions on different switches. So I needed to create TWO sub interfaces on the FortiGate (on port3).. Note: The commands in the configuration are not supported on the Catalyst 2950 with Cisco IOS Software Release 12.0(5.2)WC(1) or any software that is earlier than Cisco IOS Software Release 12.1(6)EA2. Also, make sure that no Layer 3 device is present in path of session source to session destination. Issue this command in order to delete the SPAN session that the software creates for the VPN service module: Note: If you delete the session, the VPN service module drops the multicast traffic. Refer to these documents for the related configuration: Configuring SPAN & RSPAN(Catalyst 6500/6000), Configuring SPAN & RSPAN (Catalyst 4500/4000). Your email address will not be published. The basic characteristic of a SPAN destination port is that it does not transmit any traffic except the traffic required for the SPAN session. The interface shows the port in this state in order to make it evident that the port is currently not usable as a production port. This of course assumes you are provided a /29 from the ISP (i assume so based on the . It can be monitored in multiple SPAN sessions. If a reflector port is oversubscribed, it could become congested. VSPAN is the monitoring of the network traffic in one or more VLANs. This discard protects the port from bridging loops. Remote SPAN (RSPAN)Some source ports are not located on the same switch as the destination port. So, lets test it. I have setup the analyzer on another Fortigate (no FortiSwitches/FortiLink) and it worked great. A 10/100 port reflects at 100 Mbps. This value is used to find the Virtual Path Index (VPI) of a path structure in the Virtual Path Table (VPT). In a single local SPAN session or RSPAN source session, you can monitor source port traffic, such as received (Rx), transmitted (Tx), or bidirectional (both). Press question mark to learn the rest of the keyboard shortcuts. To complete the creation of a port mirroring session, select ports or uplinks as destinations for the port mirroring session. By default, learning is enabled and the destination port learns MAC addresses from incoming packets that the port receives. I didnt know how FortiGate handled this, so I fired it up on the test bench to test FortiGate Sub Interfaces. Only one destination port is allowed per SPAN session, and the same port cannot be a destination port for multiple SPAN sessions. You can have multiple RSPAN sessions but only one ERSPAN session. Asking for help, clarification, or responding to other answers. Ingress SPAN will be done on ingress modules so SPAN performance would be the sum of all participating replication engines. However, it does not capture the traffic that flows in the actual VLAN itself. Although this document is updated to reflect changes to SPAN, refer to your switch platform documentation release notes for the latest developments on the SPAN feature. Network Analyzer/Security Device Connected to SPAN Destination Port is Not Reachable, Local SPAN, RSPAN, and ERSPAN Destinations, Getting Started Guide for the Catalyst Express 500 Switches 12.2(25)FY, Getting Started Guide for the Catalyst Express 520 Switches, Release Notes for Catalyst 2948G-L3 and Catalyst 4908G-L3 for Cisco IOS Release 12.0(10)W5(18g), SPAN on the Catalyst 2940, 2950, 2955, 2960, 2970, 3550, 3560, 3560E, 3750, and 3750E Series Switches, Local SPAN, RSPAN, and ERSPAN Session Limits, Configuring Local SPAN, Remote SPAN (RSPAN), and Encapsulated RSPAN, Configuring Local SPAN, RSPAN, and ERSPAN, Configuring Local SPAN, Remote SPAN (RSPAN), and Encapsulated RSPAN - Catalyst 6500 Series Cisco IOS Software Configuration Guide, 12.2SX, How to configure SPAN and RSPAN on Cisco Catalyst 4500 switches that run Cisco IOS Software, A SPAN destination port is shown as "not connected" and does not communicate with the rest of the network, Technical Support & Documentation - Cisco Systems, Yes Supervisor 2T with PFC4, Supervisor 720 with PFC3B or PFC3BXL running Cisco IOS Software Release 12.2(18)SXE or later. Catos 5.1 and later, you configure RSPAN to monitor source ports that carry RSPAN. Span performance would be the sum of all participating replication engines you consider architecture.
