MME SGs Service Configuration Mode Commands

MME SGs Service Configuration Mode Commands
 
The MME SGs Service Configuration Mode is used to create and manage the LTE Mobility Management Entity (MME) SGs services on this system. The SGs service creates an SGs interface between the MME and a Mobile Switching Center/Visitor Location Register (MSC/VLR).
associate
Associates or disassociates a Stream Control Transmission Protocol (SCTP) parameter template with the SGs service.
Product

Syntax
associate sctp-param-template template_name
no associate sctp-param-template
no
 
template_name
Associates an SCTP parameter template with the SGs service.
template_name specifies the name for a pre-configured SCTP parameter template to associate with this SGs service as an alphanumeric string of 1 through 63 characters. For more information on the SCTP parameter template, refer to the sctp-param-template command in the Global Configuration Mode Commands chapter and the SCTP Parameter Template Configuration Mode Commands chapter.
Usage
Use this command to associate a pre-configured SCTP parameter template with the SGs service.
note_smallImportant: If no SCTP parameter template is specified, all default settings for the configurable parameters in the SCTP Parameter Template Configuration Mode apply.
Example
The following command associates a pre-configured SCTP parameter template called sctp-3 to the SGs service:
associate sctp-param-template sctp-3
bind
Binds the service to a logical IP interface serving as the SGs interface.
Product
MME
Privilege
Administrator
Syntax
bind { ipv4-address ipv4_address [ ipv4-address ipv4_address ] | ipv6-address ipv6_address [ ipv6-address ipv6_address ] }
no bind
no bind
Removes the interface binding from this service.
ipv4-address ipv4_address [ ipv4-address ipv4_address ]
Specifies the IP address of the SGs interface in IPv4 dotted-decimal notation. n.
A secondary IPv4 address can be configured to support SCTP multi-homing.
ipv6-address ipv6_address [ ipv6-address ipv6_address ]
Specifies the IP address of the SGs interface in IPv6 colon-separated notation.
A secondary IPv6 address can be configured to support SCTP multi-homing.
Usage
Associate the SGs service to a specific logical IP address. The logical IP address or interface takes on the characteristics of an SGs interface that provides the session connectivity for circuit switched fallback (CSFB) to/from a Mobile Switching Center/Visitor Location Register (MSC/VLR). Only one interface can be bound to a service. The interface should be configured prior to issuing this command
Example
The following command binds the logical IP interface with the IPv4 address of 192.68.10.22 to the SGs service:
bind ipv4-address 192.68.10.22

no non-pool-area name [ lac value(s) ]
Removes the configured non-pool-area from this service. Optionally, removes a specific LAC or LACs from this non-pool area. name is the name of an existing non-pool-area expressed as an alphanumeric string of 1 through 63 characters. value(s) is an existing LAC integer value from 1 through 65535.
name
Specifies the name of the non-pool area as an alphanumeric string of 1 through 63 characters.
use-vlr vlr_name
Specifies the VLR to be used in this non-pool area configuration as an alphanumeric string of 1 through 63 characters.
lac value(s)
Specifies the location area code or codes to be used with the configured VLR in this non-pool area configuration. value(s) is an integer(s) from 1 through 65535. A total of 16 area codes can be added in a single line or separately.
plmnid { any | mcc mcc_value mnc mnc_value }
Specifies the Public Land Mobile Network (PLMN) identifier to be used with the VLR in this non-pool area configuration.
any: Specifies that any PLMN ID can be used with the VLR in this configuration.
mcc mcc_value mnc mnc_value: Specifies the mobile country code (MCC) and mobile network code (MNC) of the PLMN identifier. mcc_value must be an integer from 101 through 998. mnc_value must be a 2- or 3-digit integer from 00 through 998.
Usage
Use this command to configure a non-pool area where LAC values and/or PLMN IDs are associated with a specific VLR.
Example
The following command creates a non-pool area named svlr1 associated with a VLR named vlr1 and containing LAC values of 1, 2, 3, 4, 5, 6, 7, and 8:
non-pool-area svlr1 use-vlr vlr1 lac 1 2 3 4 5 6 7 8
pool-area
Creates a location area code (LAC) pool area configuration or specifies an existing pool area and enters the LAC Pool Area Configuration Mode.
Product
MME
Privilege
Administrator
Syntax
[ no ] pool-area pool_name [ -noconfirm ]
no
Removes the selected pool area configuration from the SGs service.
pool_name
Specifies the name of the LAC pool area configuration. If pool_name does not refer to an existing pool, a new pool is created. pool_name must be an alphanumeric string of 1 through 64 characters.
note_smallImportant: A total of eight pool areas can be configured per SGs service.
Usage
Use this command to enter the LAC Pool Area Configuration Mode for an existing pool area configuration or for a newly defined pool area configuration. This command is also used to remove an existing pool area configuration.
Entering this command results in the following prompt:
[context_name]hostname(config-sgs-pool-area)#
LAC Pool Area Configuration Mode commands are defined in the MME LAC Pool Area Configuration Mode Commands chapter.
