Restrictions
When you configure remote port mirroring, the following restrictions apply:
•
You can configure the same source port to be used in multiple source sessions.
•
You cannot configure a source port channel or source VLAN in a source session if the port channel or VLAN has a member port that is
configured as a destination port in a remote-port mirroring session.
•
A destination port for remote port mirroring cannot be used as a source port, including the session in which the port functions as the
destination port.
•
A destination port cannot be used in any spanning tree instance.
•
The reserved VLAN used to transport mirrored traffic must be a L2 VLAN. L3 VLANs are not supported.
•
On a source switch on which you configure source ports for remote port mirroring, you can add only one port to the dedicated RPM
VLAN which is used to transport mirrored traffic. You can configure multiple ports for the dedicated RPM VLAN on intermediate and
destination switches.
