Network Service Entity - Peer NSEI Configuration Mode Commands

The Network Service Entity (NSE) - Peer NSEI configuration mode configures the Frame Relay parameters for the peer NSE. This mode is a sub-mode of the Global Configuration mode. This sub-mode provides the commands and parameters to define the management functionality for the Gb interface between a BSS and an SGSN over a 2.5G GPRS Frame Relay network connection.

Upon accessing this mode, the prompt should be similar to:
[local]hostname(nse-fr-peer-nsei-<nse_id>)#

IMPORTANT:

The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).

bssgp-timer

This command has been deprecated.

end

Exits the current configuration mode and returns to the Exec mode.

Syntax 
end

Usage:

Return to the Exec mode.

exit

Exits the current configuration mode and returns to the previous configuration mode.

Product:

Syntax 
exit

Usage:

Return to the global configuration mode.

ns-reset-mode

The command configures automatic NS-Reset for a specific Frame Relay peer NSE (network service entity).

Platform:

ASR 5000

Product:

SGSN


Privilege:

Security Administrator, Administrator


Syntax 
ns-reset-mode { active | passive }default ns-reset-mode
default

Resets the configuration to the passive mode.

active

Configures active mode so that the SGSN is enabled to initiate NS-Reset without manual intervention.

passive

Configures passive mode which means the SGSN continues not to initiate NS-Reset.

This is the default mode.


Usage:
Use this command to configure the SGSN for active mode regarding the peer NSE, so that the SGSN will initiate:
  • NS-Reset when NSVC-DLCI binding is done.
  • NS-Reset when the link goes down and then comes back.
  • NS-Unblock upon receipt of NS-Reset-Ack message.
Active mode is useful in the following scenarios:
  • if the SGSN detects LMI down but the BSC does not detect any link failure so does not send NS-Reset.
  • if the NS layer can go down and the SGSN will mark the link as ‘Blocked-Dead’. If the link comes up later, the NS layer state for that link will remain in the Blocked state.

Example:
Configure active mode to perform NS-Reset when the link goes down and comes back up:
ns-reset-mode active
ns-vc

This command creates a network service virtual circuit (NSVC) for this frame relay NSE and enters the configuration sub-mode to define the NSVC parameters. These parameters are described in the NSVC Configuration Mode chapter elsewhere in this CLI Reference Guide.

Platform:

ASR 5000

Product:

SGSN


Privilege:

Security Administrator, Administrator


Syntax 
[ no ] ns-vc
id ns-vc_id
no

Removes the specified NSVC configuration.

id ns-vc_id

This keyword defines the NSVC configuration identifier.

ns-vc_id: Must be an integer from 0 to 65535


Usage:

Access the NSVC configuration mode.


Example:
Gain access to the NSVC configuration mode to change the 4th instance.
ns-vc id 4
