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
Follow these steps to perform configurations on the source switch:

When configuring the source switch, note that:
z All ports of a remote source mirroring group are on the same device. Each remote source mirroring
group can be configured with only one reflector port.
z The reflector port cannot be a member port of an existing mirroring group, a fabric port, a member
port of an aggregation group, or a port enabled with LACP or STP. It must be an access port and
