Configure I-SID Monitoring

Use the following procedure to configure Fabric RSPAN 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 CLI command, it overwrites the existing egress port list or egress MLT.

Procedure

In the navigation pane, expand Configuration > Edit > Diagnostics.
Click General.
Click the Monitor-By-ISID tab.
Click Insert.
Configure the parameters as required.
Click Insert.
To modify mappings, double-click a parameter to view a list of options.
Click Apply.

Monitor-By-ISID Field Descriptions

Use the data in the following table to use the Monitor-By-ISID tab.


Name	Description
Index	Specifies the entry that contains monitor by I-SID information.
MonitorIsidOffset	Configures the monitoring I-SID offset value. The offset ID is mapped to the actual monitor I-SID value to which the packets are mirrored.
MonitorIsid	Specifies the actual monitor I-SID value to which packets are mirrored.
EgressPortList	Specifies the egress ports to which traffic analyzers connect.
EgressMltId	Specifies the egress MLT ID to which traffic analyzers connect.
MapToVlanId	Specifies the VLAN ID to map with mirrored traffic on the monitoring node.
Enable	Enables or disables monitoring by I-SID.
