•
Rate-limiting tagged-VLAN egress traffic on a source port is supported.
•
In a destination session used for remote port mirroring:
•
Maximum number of destination sessions supported on a switch: 64
Maximum number ports supported in a destination session: 64
Maximum number ports supported in a destination session: 64
•
You can configure any port as a destination port. A port-channel interface is not supported as a
destination port.

•
You can configure additional destination ports in an active session.
•
You can tunnel the mirrored traffic from multiple remote-port source sessions to the same
destination port.

•
You can configure a destination port to send only tagged or untagged traffic to the analyzer. By
default, the port sends untagged packets so that the reserved VLAN ID is removed and the original
monitored packet is analyzed.

Restrictions
When you configure remote port mirroring, the following restrictions apply:
•
You cannot 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.

•

supported.
Configuration Procedure
To configure remote port mirroring, you must configure:
1. A reserved L2 VLAN used to transport (switched) mirrored packets on source, intermediate, and
destination switches
2. A source session that consists of multiple source ports, port channels, and VLANs which are
associated with the dedicated VLAN and located on different source switches
3. A destination session that consists of multiple destination ports associated with the dedicated VLAN
and located on different destination switches
