Restrictions
When you congure remote port mirroring, the following restrictions apply:
• You can congure the same source port to be used in multiple source sessions.
• You cannot congure a source port channel or source VLAN in a source session if the port channel or VLAN has a member port that is
congured 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 trac must be a L2 VLAN. L3 VLANs are not supported.
• On a source switch on which you congure source ports for remote port mirroring, you can add only one port to the dedicated RPM
VLAN which is used to transport mirrored trac. You can congure multiple ports for the dedicated RPM VLAN on intermediate and
destination switches.
