# 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.

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
