Step 3
pvc dlci
Example:
RP/0/0RP0/CPU0:router(config-if)# pvc 100
Enters serial Frame Relay PVC configuration mode for the
specified PVC.
Step 4
encap {cisco | ietf}
Example:
RP/0/0RP0/CPU0:router(config-fr-vc)#
encapsulation aal5
Configures the encapsulation for a Frame Relay PVC.
Step 5
service-policy {input | output} policy-map
Example:
RP/0/0RP0/CPU0:router (config-subif)#
service-policy output policy1
Attaches a policy map to an input subinterface or output
subinterface. Once attached, the policy map is used as the
service policy for the subinterface.
Step 6
fragment end-to-end fragment-size
Example:
RP/0/0/CPU0:router(config-fr-vc)# fragment
end-to-end 100
Enables fragmentation of Frame Relay frames on an
interface.
Replace fragment-size
with the number of payload bytes
from the original Frame Relay frame that will go into each
fragment. This number excludes the Frame Relay header of
the original frame.
On the Cisco 8-Port Channelized T1/E1 SPA, valid values
are 128, 256, and 512.
Step 7
fragment-counter
Example:
RP/0/0/CPU0:router(config-fr-vc)#
fragment-counter
Enables fragmentation counters for a Frame Relay
subinterface and PVC.
Step 8
end
or
commit
Example:
RP/0/0RP0/CPU0:router(config-serial-l2transport
-
pvc)# end
or
RP/0/0RP0/CPU0:router(config-serial-l2transport
-pvc)# commit
Saves configuration changes.
• When you issue the end command, the system prompts
you to commit changes:
Uncommitted changes found, commit them before
exiting(yes/no/cancel)?
[cancel]:
–
Entering yes saves configuration changes to the
running configuration file, exits the configuration
session, and returns the router to EXEC mode.
–
Entering no exits the configuration session and
returns the router to EXEC mode without
committing the configuration changes.
–
Entering cancel leaves the router in the current
configuration session without exiting or
committing the configuration changes.
Use the commit command to save the configuration
changes to the running configuration file and remain within
the configuration session.
