R21xx-HP FlexFabric 11900 Network Management and Monitoring Configuration Guide

Configuration restrictions and guidelines
• The reflector port of a remote source mirroring group must be an access port and belong to the
default VLAN, VLAN 1.
• HP recommends that you configure an unused port as the reflector port of a remote source mirroring
group and disable spanning tree on it.
• Do not configure a combo interface 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.
• The link type of monitor ports configured for port mirroring must be access.
