S-GW Access Peer Profile Configuration Mode Commands

MME restoration is a 3GPP specification-based feature designed to gracefully handle the sessions at S-GW once S-GW detects that the MME has failed or restarted. If the S-GW detects an MME failure based on a different restart counter in the Recovery IE in any GTP Signaling message or Echo Request / Response, it will terminate sessions and not maintain any PDN connections.

As a part of this feature, if a S-GW detects that a MME or S4-SGSN has restarted, instead of removing all the resources associated with the peer node, the S-GW shall maintain the PDN connection table data and MM bearer contexts for some specific S5/S8 bearer contexts eligible for network initiated service restoration, and initiate the deletion of the resources associated with all the other S5/S8 bearers.

Mode

This configuration mode enables operators to configure a peer profile for the Network Triggered Service Restoration feature.

Exec > Global Configuration > Peer Profile Configuration

configure > peer-profile service-type sgw-access name profile_name

Entering the above command sequence results in the following prompt: 

[local] host_name(config-peer-profile-sgw-access)#

Syntax

do show

Usage Guidelines

Use this command to run all Exec mode show commands while in Configuration mode. It is not necessary to exit the Config mode to run a show command.

The pipe character | is only available if the command is valid in the Exec mode.


Caution

There are some Exec mode show commands which are too resource intensive to run from Config mode. These include: do show support collection , do show support details , do show support record and do show support summary . If there is a restriction on a specific show command, the following error message is displayed: 

Failure: Cannot execute 'do	show support' command from Config mode.
