Entering the above command sequence results in the following prompt: 

[context_name]host_name(config-mrme-service)#

Syntax

dns-pgw { context context_name | selection { topology [ weight ] | weight } } 
{ default | no } dns-pgw { context | selection { topology [ weight ] | weight } }

default

Returns the command to its default value.

default dns-pgw context : MRME will fetch the dns-client configuration from the current context.

default dns-pgw selection topology : MRME will perform P-GW selection based on the topology.

no

If previously configured, removes the dns-pgw configuration.

context context_name

Specifies to configure the source context in which the DNS client is configured.

context_name must be an alphanumeric string of 1 through 79 characters.

selection { topology [ weight ] | weight }

Specifies to enable/disable P-GW selection based on topology and load-balancing of P-GWs based on weights from DNS.

Usage Guidelines

Use this command to configure the source context in which the DNS client is configured, or enable/disable P-GW selection based on topology and load-balancing of P-GWs, based on weights from DNS.

In case of topology-based selection, when the DNS procedure outputs a list of P-GW host names for the APN FQDN, MRME performs the longest suffix match and selects the P-GW which is topologically closest to the MRME/subscriber. In case of weight-based selection, if there are multiple entries with the same priority in the list of P-GW host names for the APN FQDN in the output from the DNS procedure, calls are distributed to the P-GWs according to the weight field in RRs. The weight field specifies a relative weight for entries with the same priority.

Example

This command will configure the source context in which the DNS client is configured to "mrmectx". 

dns-P-GW context mrmectx

fqdn

This command allows you to configure the MRME fully qualified domain name (FQDN) to match the longest suffix during dynamic allocation.

fqdn_name

Specifies the MRME FQDN name that will be used for the longest suffix match during dynamic allocation.

fqdn_name must be an alphanumeric string of 1 to 255 characters.

Usage Guidelines

Use this command to configure the MRME FQDN under MRME service to match the longest suffix during dynamic allocation.

Example

The following command sets an MRME FQDN value of "topon.eth.mrme.north.blore.3gppnetwork.org". 

fqdn topon.eth.mrme.north.blore.3gppnetwork.org

Syntax

[ no ] pgw-selection { fallback pgw-id | local-configuration-preferred }

no

Removes the configuration.

local-configuration-preferred

Specifies the SaMOG Gateway to perform P-GW selection based on local configuration.

When this keyword is enabled,

  • In the case of dynamic P-GW selection from the AAA server (APN FQDN based selection), the SaMOG Gateway first tries to establish session with the locally configured P-GWs. If the locally configured P-GWs are not reachable, APN FQDN resolution is performed, and SaMOG Gateway tries to establish session with the resolved IP addresses.

  • In the case of static P-GW selection from the AAA server (IP address or P-GW FQDN ), SaMOG tries to establish session with the AAA server provided P-GW address (IP address or resolved P-GW FQDN). If the AAA server provided P-GW addresses are not reachable, session setup fails.

fallback pgw-id

Specifies the SaMOG Gateway to trigger fall back to locally configured P-GW addresses (or DNS resolved P-GW addresses using APN FQDN) when session establishment with AAA provided P-GW address or DNS provided P-GW address for P-GW FQDN fails.

Usage Guidelines

Use this command to enable SaMOG Gateway to perform P-GW selection based on local configuration.

When the local-configuration-preferred keyword is enabled, SaMOG first uses the locally configured P-GW addresses to fall-back to. When the locally configured P-GW addresses are not reachable, SaMOG then uses APN FQDN based P-GW address resolution.

When the local-configuration-preferred keyword is not enabled, SaMOG first uses APN FQDN based P-GW address resolution to fall-back to. When the P-GW address resolved using APN FQDN is not reachable, SaMOG then uses the locally configured P-GW addresses.

When session establishment with AAA provided P-GW address or DNS provided P-GW address for P-GW FQDN fails, fall-back is triggered when the fallback pgw-id keyword is enabled.

Example

The following command enables the SaMOG Gateway to use locally configured P-GW addresses first for P-GW resolution: 

pgw-selection local-configuration-preferred

radius

This command allows you to specify the IP address and shared secret of the RADIUS accounting and authentication client from which RADIUS accounting and authentication requests are received.
