To do...
Configure the current port
as trunk port
Configure the trunk port to
permit packets from the
remote-probe VLAN
Return to system view
Create a remote source
mirroring group
Configure source port(s) for
the remote source mirroring
group
Configure the reflector port
for the remote source
mirroring group
Configure the remote-probe
VLAN for the remote source
mirroring group
When configuring the source switch, note that:
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.
The reflector port cannot be a member port of an existing mirroring group, a fabric port,
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 gets invalid if the corresponding remote port mirroring VLAN is
removed.
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
The trunk ports and the remote-probe VLAN are determined.
Layer 2 connectivity is ensured between the source and destination switches over the
remote-probe VLAN.
2) Configuration procedure
Follow these steps to perform configurations on the intermediate switch:
Use the command...
port link-type trunk
port trunk permit vlan
remote-probe-vlan-id
quit
mirroring-group group-id
remote-source
mirroring-group group-id
mirroring-port
mirroring-port-list { both |
inbound | outbound }
mirroring-group group-id
reflector-port
reflector-port
mirroring-group group-id
remote-probe vlan
remote-probe-vlan-id
1-6
