Privilege
Administrator
Syntax
[ default | no ] authorize-with-hss
[ default | no ]
Resets the command to the default setting of “authorize locally” from an internal APN authorization configuration.
Usage
Use this command to specify that the system will use the S6b interface to acquire subscriber authorization from a 3GPP AAA server and the HSS.
 
dns-client
Specifies the context to use where the DNS client resides to send DNS queries.
Product
P-GW
Privilege
Administrator
Syntax
dns-client context name
[ default | no ] dns-client context
default
Returns the command to the default setting of targeting the DNS client in the context where the P-GW service resides.
no
DNS query is disabled.
name
Specifies the name of the context where the DNS client is used for the resolution of PCSCF-FQDN received from S6b interface. name must be an existing context and be from 1 to 79 alpha and/or numeric characters.
Usage
Use this command to specify the context where the DNS client resides to perform P-CSCF-FQDN resolution from the S6b interface.
Example
The following command identifies the egress1 context as the context where the DNS client resides:
dns-client context egress1
 
end
Exits the current mode and returns to the Exec Mode.
Product
All
Privilege
Administrator
Syntaxend
Usage
Change the mode back to the Exec mode.
 
exit
Exits the current mode and returns to the previous mode.
Product
All
Privilege
Administrator
Syntaxexit
Usage
Return to the previous mode.
 
fqdn
Configures a Fully Qualified Domain Name for this P-GW service used in messages between the P-GW and a 3GPP AAA server over the S6b interface.
Product
P-GW
Privilege
Administrator
Syntax
fqdn host domain_name realm realm_name
[ default | no ] fqdn
default
Returns the command to the default setting of “null”.
no
Remove the configured FQDN from this services configuration.
hostdomain_name
Specifies the domain name of the P-GW service. domain_name must be from 1 to 255 alpha and/or numeric characters.
realmrealm_name
Specifies the realm name of the P-GW service. realm_name must be from 1 to 255 alpha and/or numeric characters.
Usage
Use this command to identify the P-GW service using an FQDN required when sending messages over the S6b interface to a 3GPP AAA server.
note_smallImportant: In order to properly interact with other nodes in the network, the FQDN should be 96 alpha and/or numeric characters or less.
Topology Matching (eHRPD only)
You may specify which P-GW you wish an HSGW interface to connect with by enabling topology matching within the FQDNs for both the HSGW service and P-GW service. Topology matching selects geographically closer nodes and reduces backhaul traffic for a specified interface.
The following optional keywords enable or disable topology matching when added to the beginning of an FQDN:
•
topon.<interface_name>.
Beginning an FQDN with topon initiates topology matching with available HSGWs in the network. Once this feature is enabled, the rest of the FQDN is processed from right to left until a matching regional designator is found on a corresponding HSGW FQDN.
•
topoff.<interface_name>.
By default, topology matching is disabled. If you enable topology matching for any interfaces within a node, however, all interfaces not using this feature should be designated with topoff.
Example
The following command configures the FQDN for this P-GW service as 123abc.all.com with a realm name of all.com:
fqdn host 123abc.all.com realm all.com
The following command configures this P-GW service with an FQDN that enables topology matching:
fqdn host topon.<interface_name>.pgw01.bos.ma.node.epc.mnc<value>.mcc<value>.3gppnetwork.org realm node.epc.<mnc>.<mcc>.3gppnetwork.org
note_smallImportant: The associated HSGW service must have a corresponding FQDN similar to the following:
topon.<interface_name>.hsgw01.bos.ma.node.epc.mnc<value>.mcc<value>.3gppnetwork.org
 
gx-li
Refer to the ASR 5000 Lawful Intercept Configuration Guide for a description of this command.
 
newcall
Configures the P-GW to accept or reject requests for a static IP address if the address is already in use by another session.
Product
P-GW
Privilege
Administrator
Syntax
newcall duplicate-subscriber-requested-address { accept | reject }
no newcall duplicate-subscriber-requested-address
no
Returns the command to the default setting of “reject”.
duplicate-subscriber-requested-address { accept | reject }
Default: reject
accept: Specifies that the old session with the requested address will be ended to accept the new session with the same address.
reject: Specifies that the new session requesting the same address will be rejected.
Usage
Use this command to configure the behavior of the P-GW service when receiving requests for static IP address already in use by other sessions.
note_smallImportant: This command is only applicable to sessions using services supporting duplicate address abort. These services include HA, GGSN, and P-GW.
Example
The following command allows for the acceptance of requests for static IP addresses already in use by other sessions:
newcall duplicate-subscriber-requested-address accept
 
plmn
Configures Public Land Mobile Network identifiers used to determine if a mobile station is visiting, roaming, or belongs to this network.
Product
P-GW
Privilege
Administrator
Syntax
plmn id mcc number mnc number [ primary ]
mcc number mnc number
mcc number: Specifies the mobile country code (MCC) portion of the PLMN’s identifier. number is the PLMN MCC identifier and must be an integer value between 100 and 999.
mnc number: Specifies the mobile network code (MNC) portion of the PLMN’s identifier. number is the PLMN MNC identifier and can be configured to any 2 or 3 digit integer value between 00 and 999.
primary
When multiple PLMN IDs are configured, the primary keyword can be used to designate one of the PLMN IDs to be used for the AAA attribute.
Usage
The PLMN identifier is used to aid the P-GW service in the determination of whether or not a mobile station is visiting, roaming, or home. Multiple P-GW services can be configured with the same PLMN identifier. Up to five PLMN IDs can be configured for each P-GW Service.
Example
The following command configures the PLMN identifier with an MCC of 462 and MNC of 02:
plmn id mcc 462 mnc 02
