VLAN Mirroring
VLAN mirroring copies traffic received in a specified VLAN to an observing port. In Figure 1, the switch copies only the packets of VLAN 10 to the monitoring device.
Similar to port mirroring, VLAN mirroring is classified into local VLAN mirroring and Layer 2 remote VLAN mirroring depending on the observing port type.
Be aware of the following:
- The switch supports only inbound VLAN mirroring. That is, the switch can copy only the packets received in a specified VLAN to observing ports.
- In Layer 2 remote VLAN mirroring, the VLAN to which the original traffic belongs must be different from the Layer 2 remote mirroring VLAN used on the intermediate Layer 2 network to forward mirrored traffic.
