mirror-source
Syntax [no] mirror-source service-id
Context debug
Description
This command configures mirror source parameters for a mirrored service.
The mirror-source command is used to enable mirroring of packets specified by the association of
the mirror-source to sources of packets defined within the context of the mirror-dest-service-id. The
mirror destination service must already exist within the system.
A mirrored packet cannot be mirrored to multiple destinations. If a mirrored packet is properly refer-
enced by multiple mirror sources (for example, a SAP on one mirror-source and a port on another
mirror-source), then the packet is mirrored to a single mirror-dest-service-id based on the following
hierarchy:
The hierarchy is structured so the most specific match criteria has precedence over a less specific
match. For example, if a mirror-source defines a port and a SAP on that port, then the SAP mirror-
source is accepted and the mirror-source for the port is ignored because of the hierarchical order of
precedence.
The mirror-source configuration is not saved when a configuration is saved. A mirror-source man-
ually configured within an ASCII configuration file will not be preserved if that file is overwritten by
a save command. Define the mirror-source within a file associated with a config exec command to
make a mirror-source persistent between system reboots.
By default, all mirror-dest service IDs have a mirror-source associated with them. The mirror-
source is not technically created with this command. Instead the service ID provides a contextual
node for storing the current mirroring sources for the associated mirror-dest service ID. The mirror-
source is automatically created when the mirror-dest service ID is created. The mirror-source is
also automatically removed when the mirror-dest service ID is deleted from the system.
The no form of the command deletes all related source commands within the context of the mirror-
source service-id. The command does not remove the service ID from the system.
Default
No mirror source match criteria is defined for the mirror destination service.
Parameters
service-id — The mirror destination service ID for which match criteria will be defined. The service-
service-id

Each entry-id must exist within the mac-filter-id. If the entry-id is renumbered within the MAC
filter definition, the old entry-id is removed from the list and the new entry-id will need to be
manually added to the list if mirroring is still desired.
If no entry-id entries are specified in the command, mirroring will not occur for that MAC filter
ID. The command will have no effect.
1. Filter entry
2. MPLS label
3. Service access port (SAP)
4. Physical port
id must already exist within the system.
Values
1 — 2147483647. The service ID must already exist as a mirror-dest.
