When configuring local port mirroring, note that:
z You need to configure the source and destination ports for the local port mirroring to
take effect.
z The source port and the destination port cannot be a member port of an existing
mirroring group; besides, the destination port cannot be a member port of an
aggregation group or a port enabled with LACP or STP.
Configuring Remote Port Mirroring
A Switch 4200G can serve as a source switch, an intermediate switch, or a destination
switch in a remote port mirroring networking environment.
Configuration on a switch acting as a source switch
1) Configuration prerequisites
z The source port, the reflector port, and the remote-probe VLAN are determined.
z Layer 2 connectivity is ensured between the source and destination switches over the
remote-probe VLAN.
z The direction of the packets to be monitored is determined.
2) Configuration procedure
Table 1-3 Follow these steps to perform configurations on the source switch:
