LMA Service Configuration Mode Commands

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.
note_smallImportant: 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 ipv6_address [ ipv4-address ipv4_address ] [ max-subscribers num ]
no bind address
no
Removes the interface binding from this service.
address ipv6_address
Specifies the IPv6 address of the interface configured as the S2a or S5/S8 interface. ipv6_address is specified in colon separated notation.
ipv4-address ipv4_address
Specifies optional IPv4 HA/P-GW address to support DSMIP6 session using IPv4 transport.ipv4_address must be entered as a standard IPv4 address in dotted decimal 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.
note_smallImportant: 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

mobility-option-type-value
Changes the mobility option type value used in mobility messages.
Product
P-GW
Privilege
Administrator
Syntax
mobility-option-type-value { custom1 | standard }
default mobility-option-type-value
default
Sets the command to the default value of custom1.
custom1
(Default) Non-standard type values used before they were defined by IANA.
standard
Standard type values as defined by IANA. In addition, standard option uses type values defined in RFC 5844 for HoA options for PMIPv6 PBU/PBA/revocation message.
Usage
Use this command to change the mobility option type value used in mobility messages.
Example
The following command changes the mobility option type value to standard:
mobility-option-type-value standard
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.
note_smallImportant: 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
default 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.
note_smallImportant: 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.
note_smallImportant: 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

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

[ default | no ] signalling-packets ip-header-dscp
default
Restores the specified parameter to its default setting of 0x0.
no
Disables the specified functionality.
ip-header-dscp value
Used to configure the QoS Differentiated Services Code Point (DSCP) marking for IP header encapsulation.
value: Represents the DSCP setting. It represents the first six most-significant bits of the ToS field. It can be configured to any hex value from 0x0 through 0x3F. Default is 0x0.
Usage
Use this command to enable or disable the DSCP marking feature for IP headers carrying outgoing signalling packets. DSCP marking is disabled by default.
Example
The following command configures the HSGW service to support DSCP marking for IP headers carrying outgoing signalling packets:
signalling-packets ip-header-dscp 0x21
simul-bindings
Specifies the maximum number of “care-of” addresses that can simultaneously be bound for the same user as identified by NAI and Home address.
Product
P-GW
Privilege
Administrator
Syntax
simul-bindings number
default simul-bindings
default
Resets the command value to the default setting of 1.
number
Default: 1
Configures maximum number of “care of” addresses that can be simultaneously bound for the same user as identified by their NAI and home address. number must be an integer value between 1 and 3.
Usage
Per RFC 5213 (and 3775), the LMA service creates a binding record known as a binding cache entry (BCE) for each subscriber session it is facilitating. Each BCE is associated with a care-of address. As the mobile node roams, it is possible that the session will be associated with a new care of address.
Typically, the LMA service will delete an old binding and create a new one when the information in the registration request changes. However, the mobile node could request that the LMA maintains previously stored BCEs. This command allows you to configure the maximum number of BCEs that can be stored per subscriber if more than one is requested.
Example
The following command configures the service to support up to 2 addresses per subscriber:
simul-bindings 2
