This section provides several configuration examples for mirroring.
7.17.1 Example for Configuring Local Port Mirroring
Networking Requirements
As shown in Figure 7-4, a Layer 2 (L2) switch is connected to GigabitEthernet 0/0/1 on the
Switch, and the incoming traffic on GigabitEthernet 0/0/1 needs to be monitored. In this case,
you can configure local port mirroring with GigabitEthernet 0/0/1 as a mirrored port and
GigabitEthernet 0/0/24 as an observing port.
