Precautions Note the following when configuring the source switch:

■All ports in a remote source mirroring group are on the same switch (the source switch). A remote source mirroring group can have only one reflector port.

■The reflector port of a mirroring group cannot be a member port of another existing mirroring group, a fabric port (only the Switch 5500/5500G have this limitation), 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 functions like VLAN-VPN, port loopback detection, packet filtering, QoS, port security, and so on.

■You cannot modify the duplex mode, port rate, and MDI attribute of a reflector port.

■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 becomes invalid if the corresponding remote-probe VLAN is removed.

■Do not configure the default VLAN, management VLAN or 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-based VLAN; otherwise, remote port mirroring may be affected.

■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.

■If the intermediate or destination switch is a Switch 5500/5500G, the bidirectional mirroring (the both keyword) function is not available.

■The Switch 4210do not support the both keyword configuration.

Note the following when configuring the destination switch:

■Packets sent from the switch CPU cannot be mirrored.
