> 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
> MME
> Privilege
> Administrator
> 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.
> Important: 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

> 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.
> Important: 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.
> Example
> The following command enters the LAC Pool Area Configuration Mode for a new or existing pool area configuration named pool1:

> Usage
> Use this command to assign the SCTP port with SCTP socket to communicate with the MSC/VLR through the SGs interface. A maximum of one SCTP port can be associated with one SGs service.
> Example
> The following command sets the SCTP port to 29118 for this service:
