Configure 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.

Variable Definitions
The following table defines parameters for the monitor-by-isid command.
Variable |
Value |
---|---|
<1–1000> |
Specifies the monitoring session. |
monitor-isid-offset <1-1000> |
Specifies the offset ID that is mapped to the actual monitor I-SID where packets are mirrored. Monitor I-SID = Base monitor I-SID + Offset ID. The base monitor I-SID is 16776000. |
egress-ports {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]} |
Specifies the port to which the analyzers connect. |
egress-mlt <1–512> |
Specifies the MLT to which the analyzers connect. |
map-to-vid <1–4093> |
Maps the mirrored packet to a specified VLAN ID for analysis. This parameter is optional. 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. |
