NOTE:
On the HP 5820X&5800 switch series, you can configure a port as the source port of multiple
mirroring groups so that traffic passing through the port can be mirrored to multiple monitor ports.
• On the HP 5800 switch series, unidirectional traffic of a source port occupies one mirroring resource,
and bidirectional traffic of a source port occupies two mirroring resources. The HP 5800 switch
series
can assign up to four mirroring resources for each source port. As a result, you can add a port to
four mirroring groups as unidirectional source ports, to two mirroring groups as bidirectional source
ports, or to three mirroring groups as a bidirectional source port in one mirroring group and
unidirectional ports in two mirroring groups.
• The HP 5820X switch series allows you to add a source port to up to two mirroring groups.
NOTE:
• A source port cannot be used as the egress or monitor port of the current or another mirroring group.
• If GVRP is enabled, GVRP may register the remote probe VLAN to unexpected ports, resulting in
undesired duplicates. For information on GVRP, see
Layer 2—LAN Switching
Configuration Guide.
Configure the mirroring ports/CPUs, the remote probe VLAN, and the egress port for the remote source
mirroring group on the source device; then, configure the remote probe VLAN and the monitor port for
the remote destination mirroring group on the destination device.
