Figure 116. Port Monitoring Example
Remote Port Mirroring
Local port monitoring allows you to monitor trac 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 trac on multiple source ports on dierent
switches and forward the mirrored trac to multiple destination ports on dierent switches.
Remote port mirroring helps network administrators monitor and analyze trac to troubleshoot network problems in a time-saving and
ecient way.
In a remote-port mirroring session, monitored trac is tagged with a VLAN ID and switched on a user-dened, nonroutable L2 VLAN. The
VLAN is reserved in the network to carry only mirrored trac, which is forwarded on all egress ports of the VLAN. Each intermediate
switch that participates in the transport of mirrored trac must be congured with the reserved L2 VLAN. Remote port monitoring
supports mirroring sessions in which multiple source and destination ports are distributed across multiple switches
