Figure 115. Port Monitoring Example
Remote Port Mirroring
Local port monitoring allows you to monitor trac from one or more source ports by directing it to a destination port on the same switch/
router. Remote port mirroring allows you to monitor Layer 2 and Layer 3 ingress and/or egress trac on multiple source ports on dierent
switches and forward the mirrored trac to multiple destination ports on dierent switches.
Remote port mirroring helps network administrators monitor and analyze trac to troubleshoot network problems in a time-saving and
ecient way.
In a remote-port mirroring session, monitored trac is tagged with a VLAN ID and switched on a user-dened, nonroutable L2 VLAN. The
VLAN is reserved in the network to carry only mirrored trac, which is forwarded on all egress ports of the VLAN. Each intermediate
switch that participates in the transport of mirrored trac must be congured with the reserved L2 VLAN. Remote port monitoring
supports mirroring sessions in which multiple source and destination ports are distributed across multiple switches
