> LMA Service Configuration Mode Commands
> The LMA Service Configuration Mode is used to create and manage the Local Mobility Anchor configuration supporting Proxy Mobile IP on a PDN Gateway in an eHRPD and E-UTRAN/EPC network.
> aaa accounting
> Enables the LMA to send AAA accounting information for subscriber sessions.
> Product
> P-GW
> Privilege
> Administrator
> Syntax
> [ default | no ] aaa accounting
> default
> Sets the command to the default condition of enabled.
> no
> Disables the ability of the LMA to send AAA accounting information.
> Usage
> Use this command to enable the LMA service to send all accounting data (start, stop, and interim) to the configured AAA servers.
> Important: In order for this command to function properly, AAA accounting must be enabled for the context in which the LMA service is configured using the aaa accounting subscriber radius command.
> Example
> The following command disables aaa accounting for the LMA service:
> no aaa accounting
> bind address
> Binds the LMA service to a logical IP interface serving as the S2a (HSGW) or S5/S8 (S-GW) interface and specifies the maximum number of subscribers that can access this service over the configured interface.
> Product
> P-GW
> Privilege
> Administrator
> Syntax
> bind address ip_address [ max-subscribers num ]
> no bind address
> no
> Removes the interface binding from this service.
> ip_address
> Specifies the IPv6 address of the interface configured as the S2a or S5/S8 interface. ip_address is specified in colon separated notation.
> max-subscribers num
> Default: 3000000
> Specifies the maximum number of subscribers that can access this service on this interface. num must be configured to an integer between 0 and 3,000,000.
> Important: The maximum number of subscribers supported is dependant on the license key installed and the number of active PSCs in the system. A fully loaded system with 13 active PSCs can support 3,000,000 total subscribers. Refer to the license key command and the Usage section (below) for additional information.
> Usage
> Associate the LMA service to a specific logical IP address. The logical IP address or interface takes on the characteristics of an S2a or S5/S8 interface that provides the session connectivity to an HSGW (S2a) or S-GW (S5/S8). Only one interface can be bound to a service. The interface should be configured prior to issuing this command.
> This command also sets a limit as to the number of simultaneous subscribers sessions that can be facilitated by the service/interface at any given time.
> When configuring the max-subscribers option, be sure to consider the following:

> • | The total number of S2a or S5/S8 interfaces you will configure

> • | The total number of subscriber sessions that all of the configured interfaces may handle during peak busy hours

> • | An average bandwidth per session multiplied by the total number of sessions

> • | The type of physical port (10/100Base-T or 1000Base-Tx) that these interfaces will be bound to

> Taking these factors into account and distributing your subscriber session across all available interfaces will allow you to configure your interfaces to optimally handle sessions without degraded performance.
> Example
> The following command would bind the logical IP interface with the address of 4551:0db8:85a3:08d3:3319:8a2e:0370:1344 to the LMA service and specifies that a maximum of 300,000 simultaneous subscriber sessions can be facilitated by the interface/service at any given time:
> bind address 4551:0db8:85a3:08d3:3319:8a2e:0370:1344 max-subscribers 300000

> refresh-advice-option
> Configures inclusion of a refresh advice option in the binding acknowledgement message sent by the LMA.
> Product
> P-GW
> Privilege
> Administrator
> Syntax
> [ default | no ] refresh-advice-option
> default
> Returns the command setting to the default setting of disabled.
> no
> Disables the inclusion of the refresh advice option in the binding acknowledgement message sent by the LMA
> Usage
> Use this command to enable the LMA to include this option in a binding acknowledgment sent to the requesting MAG. The option provides a “hint” to the MAG of when it should refresh the binding.
> As defined in RFC 3775 “Mobility Support in IPv6”, the binding refresh advice option can only be present in the binding acknowledgement sent from the mobile node's home agent in reply to a registration request. A refresh interval parameter determines the amount of time until the mobile node must send a new registration to the home agent to avoid de-registration and loss of session.
> Important: Refer to the refresh-interval-percent and reg-lifetime commands for a complete understanding of registration (binding) lifetimes and refresh intervals.
> refresh-interval-percent
> Configures percentage of the granted registration lifetime to be used in the refresh interval mobility option in a binding acknowledgement message sent by the LMA service.
> Product
> P-GW
> Privilege
> Administrator
> Syntax
> refresh-interval-percent number
> defautl refresh-interval-percent
> default
> Resets the command value to the default setting of 75.
> number
> Default: 75
> Sets the percent value for session lifetimes for this service.
> number must be an integer value from 1 to 99.
> Usage
> Use this command to configure the amount of the granted registration lifetime to be used in the refresh interval mobility option in the binding acknowledgement message sent by the LMA service to the requesting MAG.
> Refreshing a binding or registration is based on the granted registration lifetime. Since a refresh request must be within the granted range of a registration lifetime, this command provides a method of setting the interval of when a refresh request is sent.
> As described in RFC 3775 “Mobility Support in IPv6”, if a binding refresh advice option is present in the binding acknowledgement, the refresh interval field in the option must be a value less than the binding lifetime (also returned in the binding acknowledgement). The mobile node then should attempt to refresh its registration at the shorter refresh interval. The home agent will still honor the registration for the lifetime period, even if the mobile node does not refresh its registration within the refresh period.
> Important: Refer to the refresh-advice-option and reg-lifetime commands for a complete understanding of registration (binding) lifetimes and refresh intervals.
> Example
> The following command sets the refresh interval percent to 90:
> refresh-interval-percent 90
> reg-lifetime
> Configures the Mobile IPv6 session registration lifetime for this service.
> Product
> P-GW
> Privilege
> Administrator
> Syntax
> reg-lifetime seconds
> default reg-lifetime
> default
> Resets the command value to the default setting of 600.
> seconds
> Default: 600
> Sets the time value for session lifetimes for this service.
> seconds must be an integer value from1 to 262140.
> Usage
> Use this command to limit PMIPv6 lifetime on this service. If the PBU contains a lifetime shorter than what is specified, it is granted. If the lifetime is longer, then HA service will limit the granted lifetime to the configured value.
> Important: Refer to the refresh-interval-percent and refresh-advice-option commands for a complete understanding of registration (binding) lifetimes and refresh intervals.
> Example
> The following command sets the registration lifetime for Mobile IPv6 sessions using this service to 1200 seconds (20 minutes):
> reg-lifetime 1200
> revocation
> Enables the MIP revocation feature and configures revocation parameters.
> Product
> P-GW
> Privilege
> Administrator
> Syntax
> revocation { enable | max-retransmission number | retransmission-timeout msecs }
> default revocation { enable | max-retransmission | retransmission-timeout }
> no revocation enable
> default
> Resets the keyword to its default value.
> no
> Disables revocation for this service.
> enable
> Default: disabled
> Enables the MIP registration revocation feature for the LMA service. When enabled, if revocation is negotiated with a MAG and a MIP binding is terminated, the LMA can send a Revocation message to the MAG. This feature is disabled by default.
> max-retransmission number
> Default: 3
> The maximum number of retransmissions of a Revocation message before the revocation fails. number must be an integer value from 0 through 10.
> retransmission-timeout msecs
> Default: 3000
> The number of milliseconds to wait for a Revocation Acknowledgement from the MAG before retransmitting the Revocation message. msecs must be an integer value from 500 through 10000.
> Usage
> Use this command to enable or disable the MIP revocation feature on the LMA or to change settings for this feature.
> Example
> The following command sets the maximum number of retries for a Revocation message to 6:
> revocation max-retransmission 6
> The following command sets the timeout between retransmissions to 10:
> revocation retransmission-timeout 10
> sequence-number-validate
> Configures sequence number validation of the received MIPv6 control packets by the LMA service according to RFC 3775.
> Product
> P-GW
> Privilege
> Administrator
> Syntax
> [ default | no ] sequence-number-validate
> default
> Resets the command value to the default setting of enabled.
> no
> Disables the feature.
> Usage
> Use this command to configure the sequence number validation of the received MIPv6 control packets (PBUs) by the LMA service. This feature validates MIPv6 control packets and insures that any incoming packets with a sequence number prior to the last number received is consider invalid.
> If this service has no cache entry of the home address included in the PBU, it will accept any sequence value in the initial PBU from the mobile node.
> setup-timeout
> The maximum amount of time allowed for session setup.
> Product
> P-GW
> Privilege
> Administrator
> Syntax
> setup-timeout seconds
> default setup-timeout
> default
> Resets the command value to the default setting of 60.
> seconds
> Default: 60 seconds
> The maximum amount of time, in seconds, to allow for setup of a session in this service. seconds must be an integer value from 1 through 1000000.
> Usage
> Use this command to set the maximum amount of time allowed for setting up a session.
> Example
> The following command sets the maximum time allowed for setting up a session to 5 minutes (300 seconds):
> setup-timeout 300
> timestamp-replay-protection
> Designates timestamp replay protection scheme as per RFC 4285.
> Product
> P-GW
> Privilege
> Administrator
> Syntax
> timestamp-replay-protection tolerance seconds
> [ default | no ] timestamp-replay-protection tolerance
> default
> Resets the command value to the default setting of 7.
> no
> Disables the timestamp replay protection feature.
> seconds
> Default: 7
> Defines the acceptable difference in timing (between timestamps) before rejecting packet, in seconds. seconds must be an integer value between 0 and 65535.
> Usage
> Use this command to define the acceptable difference in timing (between timestamps) before rejecting packet.
> Example
> The following command sets the acceptable difference for timestamps to 10 seconds:
> timestamp-replay-protection tolerance 10
