CN4093 Application Guide for N/OS 8.3
This section describes the composition of monitored packets in the CN4093, based
on the configuration of the ports.
 Packets mirrored at port egress are mirrored prior to VLAN tag processing and
may have a different PVID than packets that egress the port toward their actual
network destination.
 Packets mirrored at port ingress are not modified.
The following procedure may be used to configure port mirroring for the example
shown in Figure 65 on page
CN 4093(config)# port-mirroring enable
CN 4093# show port-mirroring
Port mirroring is enabled
