Configuration Commands
fc
Syntax fc fc-name
no fc
Context config>mirror>mirror-dest
Description
This command specifies a forwarding class for all mirrored packets transmitted to the destination
SAP or SDP overriding the default (be) forwarding class. All packets are sent with the same class of
service to minimize out of sequence issues. The mirrored packet does not inherit the forwarding class
of the original packet.
When the destination is on a SAP, a single egress queue is created that pulls buffers from the buffer
pool associated with the fc-name.
When the destination is on an SDP, the fc-name defines the DiffServ based egress queue that will be
used to reach the destination. The fc-name also defines the encoded forwarding class of the encapsu-
lation.
The no form of the command reverts the mirror-dest service ID forwarding class to the default for-
warding class.
Default
The best effort (be) forwarding class is associated with the mirror-dest service ID.
Parameters
fc-name — The name of the forwarding class with which to associate mirrored service traffic. The
mirror-dest
Syntax mirror-dest service-id [type {ether | frame-relay | ppp | atm-sdu}]
no mirror-dest
Context config>mirror
Description
This command creates a context to set up a service that is intended for packet mirroring. It is config-
ured as a service to allow mirrored packets to be directed locally (within the same 7750 SR router) or
remotely, over the core of the network and have a far end 7750 SR decode the mirror encapsulation.
The mirror-dest service is comprised of destination parameters that define where the mirrored pack-
ets are to be sent. It also specifies whether the defined service-id will receive mirrored packets from
far end 7750 SR devices over the network core.
Only 31 mirror-dest service IDs can be created without the remote-only flag specified within a sin-
gle system.
The mirror-dest service IDs are persistent between boots of the router and are included in the config-
uration saves. The local sources of mirrored packets for the service ID are defined within the debug
mirror mirror-source command that references the same service-id. Up to 255 mirror-dest service
IDs can be created within a single system.

forwarding class name must already be defined within the system. If the fc-name does not exist,
an error will be returned and the fc command will have no effect. If the fc-name does exist, the
forwarding class associated with fc-name will override the default forwarding class.
