Configuring Local Port Mirroring - H3C S3100 Series Operation Manual

Switch
Destination switch
Do not configure the default VLAN (VLAN 1), the port VLAN, or a dynamic VLAN as the remote
probe VLAN.
Configure all ports connecting the devices in the remote-probe VLAN as trunk ports, and ensure
the Layer 2 connectivity from the source switch to the destination switch over the remote-probe
VLAN.
Do not configure a Layer 3 interface for the remote-probe VLAN, run other protocol packets, or
carry other service packets on the remote-prove VLAN and do not use the remote-prove VLAN as
the voice VLAN and protocol VLAN; otherwise, remote port mirroring may be affected.
