Physical and Layer 2 Interfaces
Software Release 2.7.1
C613-02021-00 REV F
Parameters for setting the interface defaults for encryption and
compression are also set with the CREATE command. These values are
used by all DLCs on the interface unless specifically overridden for a
particular DLC.
After the Frame Relay interface is created, to change the LMI parameters,
enter the command:
SET FRAMERELAY
You may modify any or all of the parameters on a single command line.
However, only ENCAPSULATION, NT1, NN1, NN2 and NN3 parameter
changes take effect immediately. All other parameter changes cause the
Frame Relay interface to reset automatically before they take effect.
To display the current values of the parameters, enter the command:
SHOW FRAMERELAY CONFIG
2. Add static DLCs if required
If the LMI dialogue is turned off for a Frame Relay interface, the router is
not informed about active DLCs. Therefore you must set up static DLCs. To
set up static DLCs, enter the command:
ADD FRAMERELAY=fr-interface DLC=dlci
[COMPRESSION={DEFAULT|ON|OFF}]
[ENCAPSULATION={DEFAULT|IETF|CISCO}]
[ENCRYPTION={DEFAULT|ON|OFF}]
To remove static DLCs, enter the command:
DELETE FRAMERELAY DLC
If no encryption or compression parameters are specified when the DLC is
added, the interface defaults, which are set via the DEFENCRYPTION and
DEFCOMPRESSION parameters of the CREATE FRAMERELAY and the
SET FRAMERELAY commands, are used for the DLC.
To set the encryption and compression parameters, and the CIR
(Committed Information Rate), of an individual DLC, use the SET
FRAMERELAY DLC command. If a parameter is set to a non-default value
for a DLC that the router is not informed about by the LMI, a DLC is
created to record this information. The DLC is put into the AWAIT_LMI
state until the network informs the router via the LMI that the DLC is
active.
Obtain the actual values to use for DLCs from the administrators of the
Frame Relay network to which your router is connected. Communication
across the Frame Relay network will only occur for those DLCs that are
statically configured.
If the LMI dialogue is enabled it is not possible to use static DLCs. In this case, DLCs
are learned through the LMI dialogue.
