port
Syntax port {port-id | lag lag-id} {[egress] [ingress]}
no port {port-id | lag lag-id} [egress] [ingress]
Context debug>mirror-source
Description This command enables mirroring of traffic ingressing or egressing a port (Ethernet port, SONET/
SDH channel, TDM channel, or Link Aggregation Group (LAG)).
The port command associates a port or LAG to a mirror source. The port is identified by the port-id.
The defined port may be Ethernet, SONET/SDH, access or network, or TDM channel, access. A net-
work port may be a single port or a Link Aggregation Group (LAG) ID. When a LAG ID is given as
the port-id, mirroring is enabled on all ports making up the LAG. If the port is a SONET/SDH inter-
face, the channel-id must be specified to identify which channel is being mirrored. Either a LAG port
member or the LAG port can be mirrored.
The port is only referenced in the mirror source for mirroring purposes. The mirror source association
does not need to be removed before deleting the card to which the the port belongs. If the port is
removed from the system, the mirroring association will be removed from the mirror source.
The same port may not be associated with multiple mirror source definitions with the ingress param-
eter defined. The same port may not be associated with multiple mirror source definitions with the
egress parameter defined.
If a SAP is mirrored on an access port, the SAP mirroring will have precedence over the access port
mirroring when a packet matches the SAP mirroring criteria. Filter and label mirroring destinations
will also precedence over a port-mirroring destination.
If the port is not associated with a mirror-source, packets on that port will not be mirrored. Mirroring
may still be defined for a SAP, label or filter entry, which will mirror based on a more specific criteria.
The encapsulation type on an access port or channel cannot be changed to Frame Relay if it is being
mirrored.
The no port command disables port mirroring for the specified port. Mirroring of packets on the port
may continue due to more specific mirror criteria. If the egress or ingress parameter keywords are
specified in the no command, only the ingress or egress mirroring condition will be removed.
Default No ports are defined.
