> 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 MSC/VLR.
> 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 IPv4 address of the SGs interface. ipv4_address must be specified in IPv4 dotted decimal notation.
> A secondary IPv4 address can be configured to support SCTP multi-homing.
> ipv6-address ipv6_address [ ipv6-address ipv6_address ]
> Specifies the IPv6 address of the SGs interface. ipv6_address must be specified 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 111.223.334.445 to the SGs service:
> bind ipv4-address 111.223.334.445
> end
> Exits the current mode and returns to the Exec Mode.
> Product
> All

> exit
> Exits the current mode and returns to the previous mode.
> Product

> Usage
> Use this command to configure a non-pool area where LAC values and/or PLMNIDs 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, 8, and 9:
> non-pool-area svlr1 use-vlr vlr1 lac 1 2 3 4 5 6 7 8 9
> pool-area
> Creates a LAC pool are 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 from 1 to 64 alpha and/or numeric characters.
> 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:
> pool-area pool1
