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, 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.
Configuration on a switch acting as an intermediate switch
1) Configuration prerequisites
z The trunk ports and the remote-probe VLAN are determined.
z Layer 2 connectivity is ensured between the source and destination switches over the
remote-probe VLAN.
2) Configuration procedure
Table 1-4 Follow these steps to perform configurations on the intermediate switch:
