Figure 115. Port Monitoring Example
Remote Port Mirroring
Local port monitoring allows you to monitor traffic 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 traffic on multiple source ports on different
switches and forward the mirrored traffic to multiple destination ports on different switches.
Remote port mirroring helps network administrators monitor and analyze traffic to troubleshoot network problems in a time-saving and
efficient way.
In a remote-port mirroring session, monitored traffic is tagged with a VLAN ID and switched on a user-defined, nonroutable L2 VLAN. The
VLAN is reserved in the network to carry only mirrored traffic, which is forwarded on all egress ports of the VLAN. Each intermediate
switch that participates in the transport of mirrored traffic must be configured with the reserved L2 VLAN. Remote port monitoring
supports mirroring sessions in which multiple source and destination ports are distributed across multiple switches
