disabled : Disables using AAA distributed WiMAX Mobile IP (MIP) keys for authenticating MIP RRQ.

optional : Uses AAA distributed WiMAX MIP keys for authenticating RRQ with fallback option to use static/3GPP2 based MIP keys.

required : AAA distributed WiMAX MIP keys for authenticating MIP RRQ are mandatory

dmu-refresh-key

Typically, when a Dynamic Mobile IP Update (DMU) resets, the next MIP re-registration causes MN-HA authorization failure and the HA rejects the MIP RRQ. This parameter enables the HA to retrieve the MN-HA key again from the AAA during the call and to use the freshly retrieved key value to recheck authentication.

Default is disabled.

imsi-auth

Enable uses the International Subscriber Mobile identity (IMSI) to determine if MN-AAA or MN-FAC extensions are not present in the RRQ.

Default is disabled.

mn-aaa { allow-noauth | always | dereg-noauth | noauth | renew-reg-noauth | renew-and-dereg-noauth }

Specifies how mobile node-to-AAA authentication extension in registration requests from the mobile node should be handled by the HA service.

Default is always.

allow-noauth : Specifies that the HA service does not require authentication for every mobile node registration request. However, if the mn-aaa extension is received, the HA service will authenticate it.

always : Specifies that the HA service will perform authentication each time a mobile node registers.

dereg-noauth : Disables authentication request upon de-registration.

noauth : Specifies that the HA service will not look for mn-aaa extension and will not authenticate it.

renew-reg-noauth : Specifies that the HA service will not perform authentication for mobile node re-registrations. Initial registration and de-registration will be handled normally.

renew-and-dereg-noauth : Disables authentication request upon re-registration and de-registration.

Syntax

bind address { range_IPv4address ip_mask | range_IPv4address/bitmask } [ max-subscribers count ] 
no bind address 

range_IPv4address ip_mask | range_IPv4address/bitmask

Specifies the pool of IP addresses (in IPv4 dotted-decimal notation) of the interface configured as the Pi interface with an enterprise HA (EHA). ip_mask and bitmask specifies the number of subnet bits, representing the subnet mask in CIDR notation and must be a value between 1 to 32.

range_IPv4address is a preconfigured range of IPv4 addresses in Loopback Interface Configuration Mode to enable the Enterprise HA support with enhanced capacity and configured

max-subscribers count

Default: 2500000

Specifies the maximum number of subscribers that can access this service on this interface.

count can be configured to an integer from 0 through 4000000.


Important


The maximum number of subscribers supported is dependant on the license key installed and the number of active packet processing cards installed in the system.


Usage Guidelines

Associate the HA service to a specific logical IP address. The logical IP address or interface takes on the characteristics of a Pi interface. 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 interfaces that you will configuring for use as Pi interfaces

  • The maximum number of subscriber sessions that all of these interfaces may handle during peak busy hours

  • The average bandwidth for each of the sessions

  • The type of physical port to which these interfaces will be bound

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.

IP range support is provided through ranged_address value. This value enables the pool of IPv4 addresses to support Enterprise HA on HA service to connect enhanced number of enterprise nodes. Refer HA Administration Guide for more information.

Use the no bind address command to delete a previously configured binding.

Example

The following command would bind the logical IP interface with the address of 209.165.201.1 to the HA service and specifies that a maximum of 600 simultaneous subscriber sessions can be facilitated by the interface/service at any given time.

bind address 209.165.201.1
max-subscribers 600 

The following command disables a binding that was previously configured:

no bind address 
The following command binds the range of IP addresses with HA service to be used with Enterprise HA support:

no policy overload [ redirect address [ address2...address16 ] ]

Deletes a previously set policy or removes a redirect IP address.

overload : Without any options deletes the complete overload policy from the PDSN service.

overload redirect address [ address2 ... address16 ]: deletes up to 16 IP addresses from the overload redirect policy. The IP addresses must be expressed in IP v4 dotted-decimal notation

redirect address [ weight weight_num ] [ address2 [ weight weight_num ] ... address16 [ weight weight_num ]

This option enables a redirect policy for overloading conditions. When a redirect policy is invoked, the HA service rejects new sessions with a Registration Reply Code of 136H (unknown home agent address) and provides the IP address of an alternate HA. This command can be issued multiple times.

address : The IP address of an alternate HA expressed in IP v4 dotted-decimal notation. Up to 16 IP addresses can be specified either in one command or by issuing the redirect command multiple times. If you try to add more than 16 IP addresses to the redirect policy, the CLI issues an error message. If you specify an IP address and weight that already exists in the redirect policy the new values override the existing values.

weight weight_num : When multiple addresses are specified, they are selected in a weighted round-robin scheme. Entries with higher weights are more likely to be chosen. If a weight is not specified the entry is automatically assigned a weight of 1. weight_num must be an integer from 1 through 10.

reject [ use-reject-code { admin-prohibited | insufficient-resources } ]

This option causes any overload traffic to be rejected. If no reject code is specified, the HA sends a registration reply code of 81H (admin-prohibited).

use-reject-code { admin-prohibited | insufficient-resources } : Use the specified reject code when rejecting traffic.

admin-prohibited : When this keyword is specified and traffic is rejected, the error code 81H (admin-prohibited) is returned.

insufficient-resources : When this keyword is specified and traffic is rejected, the error code 82H (insufficient resources) is returned.

Usage Guidelines

The system invokes the overload policy if the number of calls currently being processed exceeds the licensed limit for the maximum number of sessions supported by the system.

no

Indicates the reverse tunnel option is to be disabled. When omitted, the reverse tunnel option is enabled.

default

Indicates the reverse tunnel option is to be set to the default. When omitted, the reverse tunnel option is enabled.

Usage Guidelines

Reverse tunneling involves tunneling datagrams originated by the mobile node to the HA service via the FA.

When an MN arrives at a foreign network, it listens for agent advertisements and selects an FA that supports reverse tunnels. The MN requests this service when it registers through the selected FA. At this time, the MN may also specify a delivery technique such as Direct or the Encapsulating Delivery Style.

Among the advantages of using reverse-tunneling are that:
  • All datagrams from the mobile node seem to originate from its home network

  • The FA can keep track of the HA to which the mobile node is registered and tunnel all datagrams from the mobile node to its HA

Use the no version of this command to disable reverse tunneling. If reverse tunneling is disabled, and the mobile node does not request it, triangular routing will be performed.

Routing will be used.

The default setting is reverse tunnel enabled.


Important


If reverse tunneling is disabled on the system and a mobile node requests it, the call will be rejected with a reply code of 74H (reverse-tunneling unavailable).

trigger { handoff | idle-timeout }

handoff : Default: Enabled

Triggers the HA to send a Revocation message to the FA when an inter-Access Gateway/FA handoff of the MIP session occurs. If this is disabled, the HA is never triggered to send a Revocation message.

idle-timeout : Default: Enabled

Triggers the HA to send a Revocation message to the FA when a session idle timer expires.

Usage Guidelines

Use this command to enable or disable the MIP revocation feature on the HA or to change settings for this feature. Both the HA and the FA must have Registration Revocation enabled and FA/HA authorization must be in use for Registration Revocation to be negotiated successfully.

Example

The following command enables Registration Revocation on the HA:
revocation enable 
The following command sets the maximum number of retries for a Revocation message to 10 :
revocation max-retransmission 10  
The following command sets the timeout between retransmissions to 3 :
revocation retransmission-timeout 3 
The behavior of send MIP revocation to FA is as follows:
  • 1st retry: Retransmit in 3 seconds after previous MIP revocation send.

  • 2nd retry: Retransmit in 6 seconds after previous MIP revocation send (9 seconds after sending initial MIP revocation).

  • 3rd retry: Retransmit in 12 seconds after previous MIP revocation send (21 seconds after sending initial MIP revocation).

  • 4th retry: Retransmit in 24 seconds after previous MIP revocation send (45 seconds after sending initial MIP revocation).

  • 5th retry: Retransmit in 48 seconds after previous MIP revocation send (93 seconds after sending initial MIP revocation).

Configures the maximum number of simultaneous "care-of" bindings that the HA service will maintain for any given subscriber.

is an integer from 1 through 3.

Usage Guidelines

Per RFC 2002, the HA service creates a mobile binding record (MBR) for each subscriber session it is facilitating. Each MBR 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 HA service will delete an old binding and create a new one when the information in the Registration Request changes. However, the mobile could request that the HA maintain previously stored MBRs. This command allows you to configure the maximum number of MBRs that can be stored per subscriber if the requested. The default value is 3.

Example

The following command configures the HA service to support up to 4 MBRs per subscriber:
simul-bindings 4 

threshold dereg-reply-error

Default: 0

Specifies the high threshold number of de-registration reply errors that must be met or exceeded within the polling interval to generate an alert or alarm. It can be configured to an integer from 0 through 100000.

clear low_thresh

Default: 0

The low threshold number of de-registration reply errors that must be met or exceeded within the polling interval to clear an alert or alarm. It can be configured to an integer from 0 through 100000.


Important


This value is ignored for the Alert model. In addition, if this value is not configured for the Alarm model, the system assumes it is identical to the high threshold.


Usage Guidelines

Use this command to set an alert or an alarm when the number of de-registration reply errors is equal to or greater than a specified number of calls per second.

Alerts or alarms are triggered for the number of de-registration reply errors on the following rules:
  • Enter condition: Actual number of de-registration reply errors > High Threshold

  • Clear condition: Actual number of de-registration reply errors < Low Threshold

Example

The following command configures a de-registration reply error threshold of 1000 and a low threshold of 500 for a system using the Alarm thresholding model:
