In the following example, the host and server are exchanging traffic which passes through the uplink interface 1/1. Port 1/1 is
the monitored port and port 1/42 is the destination port, which is configured to only monitor traffic received on
tengigabitethernet 1/1 (host-originated traffic).
Figure 111. 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
