Remote port monitoring
Remote port monitoring allows you to monitor ingress and/or egress trac on multiple source ports of multiple devices and forward the
monitored trac to multiple destination ports on dierent remote devices. Remote port monitoring helps network administrators monitor
and analyze trac to troubleshoot network problems in a time-saving and ecient way.
In a remote port monitoring session, monitored trac is tagged with a VLAN ID and switched on a user-dened, non-routable L2 VLAN.
The VLAN is reserved in the network to carry only monitored trac, which is forwarded on all egress ports of the VLAN. You must
congure each intermediate switch that participates in the transport of monitored trac with the reserved L2 VLAN. Remote port
monitoring supports monitoring sessions in which multiple source and destination ports distribute across multiple network devices.
