Configuring Remote Port Mirroring 85
Configuring Remote
Port Mirroring
While configuring remote port mirroring, you need to configure the remote source
port mirroring group and the remote destination port mirroring group on both
devices.
Configuring a Remote
Source Mirroring Group
You need to configure source ports, reflector ports, and remote port mirroring
VLAN for a remote source mirroring group.
Follow these steps to configure a remote source port mirroring group:
n
■ All the ports (including the source ports and the reflector port) of a remote
source mirroring group can only belong to the same single device.
■ Do not add source ports to remote port mirroring VLANs for fear of
interrupting device operation.
■ Only the ports that are of the access type and belong to the default VLANs can
be reflector ports. Member ports of existing port mirroring groups or
destination stream mirroring ports cannot be reflector ports.
■ Do not enable any of the following on a reflector port: 802.1x, QinQ, port
loopback, and service loopback. Besides, to avoid interrupting device
operation, do not enable static ARP or MAC address learning on reflector ports
either.
■ Outbound ports cannot be the reflector port.
