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 member port of an
aggregation group, or a port enabled with LACP or STP. It must be an access port and cannot be
configured with the functions like VLAN-VPN, port loopback detection, QoS, port security, and so
on.
z
You cannot modify the duplex mode, port rate, and MDI attribute of a reflector port.
z
Only an existing static VLAN can be configured as the remote-probe VLAN. To remove a
remote-probe VLAN, you need to restore it to a normal VLAN first. A remote port mirroring group
gets invalid if the corresponding remote port mirroring VLAN is removed.
z
Do not configure a port connecting the intermediate switch or destination switch as the mirroring
source port. Otherwise, traffic disorder may occur in the network.
