Configuring I-SID Monitoring

Use the following procedure to configure Fabric RSPAN (Mirror to I-SID) on the Backbone Edge Bridge (BEB) connected to the monitor station.

Note

Do not configure the source of mirrored traffic (mirroring to an I-SID) and the analyzer (monitoring an I-SID) on the same local device with the same I-SID offset. If you require mirroring and monitoring on the same local device, use standard port-based mirroring instead of Fabric RSPAN. Fabric RSPAN mirrors traffic into an I-SID of the SPB Fabric network and monitors traffic on the remote device; the network analyzer resides on the remote monitoring device and not on the same local device.

Note

If you change the egress port or egress MLT for a particular session using a separate CLI command, it overwrites the existing egress port list or egress MLT.

1. Enter Global Configuration mode:

   enable

   configure terminal

2. Create a monitor by I-SID entry:
   

   Note

   If you use the Extreme Integrated Application Hosting (IAH) port 1/s1 as the analyzer port on the monitoring BEB for remote mirroring, you must associate it to VLAN ID 4091.

   monitor-by-isid <1–1000> [monitor-isid-offset <1-1000> {egress-mlt <1–512> | egress-ports {slot/port[/sub-port][-slot/port[/sub-port]][,...]}} [map-to-vid <1–4093>]]

3. Configure map to VLAN ID:

   monitor-by-isid <1–1000> map-to-vid <1–4093>

4. Configure egress MLT:

   monitor-by-isid <1–1000> egress-mlt <1–512>

5. Configure egress port:

   monitor-by-isid <1–1000> egress-ports {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

6. Enable monitoring by I-SID entry:

   monitor-by-isid <1–1000> enable

   

   Note

   Disable the entries (egress ports, MLT, and VLAN ID) to modify or remove parameters in the existing configuration.
