Configuration restrictions and guidelines
When you use the remote probe VLAN to enable local port mirroring to support multiple monitor ports,
follow these restrictions and guidelines:
• HP recommends that you configure an unused port as the reflector port of a remote source mirroring
group and not connect the port to a cable.
Before you configure a port as a reflector port, make sure all configurations on the port are removed.
•
You cannot configure any other features on the port after it is configured as a reflector port.
A mirroring group can contain multiple source ports.
•
To make sure the port mirroring function works properly, do not assign a source port to the remote
•
probe VLAN.
If you have already configured a reflector port for a remote source mirroring group, you can no
•
longer configure an egress port for it.
• A VLAN can serve as the remote probe VLAN for only one remote source mirroring group. HP
recommends that you use the remote probe VLAN for port mirroring exclusively. Do not create a
VLAN interface for the VLAN or configure any other features for the VLAN.
A remote probe VLAN must be a static VLAN. To remove the VLAN configured as a remote probe
•
VLAN, you must first remove the remote probe VLAN with the undo mirroring-group remote-probe
vlan command.
If the remote probe VLAN of a remote mirroring group is removed, the remote mirroring group will
•
become invalid.
Configuration procedure
To configure local port mirroring with multiple monitor ports:
Step
1. Enter system view.
2. Create a remote source
mirroring group.
3. Configure source ports
for the remote source
mirroring group.
4. Configure the reflector
port for the remote
source mirroring group.
5. Create the remote
probe VLAN and enter
VLAN view.
