NE2552E Application Guide for ENOS 8.4
This section describes the composition of monitored packets in the NE2552E, 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 60 on page
NE2552E(config)# port-mirroring enable
NE2552E# show port-mirroring
Port mirroring is enabled
