> On receipt of R4 control or data path registration request message the ASN GW service checks whether non-anchor DPF/Authenticator ASN GW/ASN PC-LR address received in request message is in trusted peer ASN GW/ASN PC-LR list configured with this command. If the Anchor DPF/Authenticator ASN GW/ASN PC-LR address received in request message is not there (or not configured) in non-anchor ASN GW or non-anchor ASN PC/LR peers list the ASN GW service sends response for request message with Failure Indication TLV with unspecified error code.
> A maximum of 32 ASN GWs or ASN PC/LRs can be configured with this command.

> ms-unexpected-network-reentry
> Default: allow
> Configures the ASN Gateway to allow/disallow an MS re-entry from the same or a new BS, when an active call already exists for the same MS on the ASN Gateway.
> This policy performs in the following manner:

> • | If the pre-attachment request of the new call comes from a different BS, re-entry is accepted regardless of the call state.

> • | If the pre-attachment request of the new call comes from the same BS, re-entry is accepted if the original call is in any state past the pre-attachment phase.

> • | Original call is dropped in favor of new call.

> msid-dhcp-chaddr-mismatch
> Default: disallow
> Configures the ASN Gateway to allow/disallow an MS to connect if MSID and DHCP address information mismatched.
> non-anchor-mode
> Default: allow
> Configures the ASN Gateway to allow/disallow the creation of non-anchor sessions based on DP Registration Request from any Base Station.
> When non-anchor mode is not allowed and a DP Registration Request is received, and there is no matching session for the MSID, the request is rejected and a DP Registration Response is sent with an error code as “Admin Prohibited”.
> allow
> Sets the policies to allow the MS matching with specified policy for ASN Gateway.
> disallow
> Sets the policies to deny/disallow the MS matching with specified policy for ASN Gateway.

> default policy asngw-initiated-reauth [ max-cmac-key-count | pmk-grace-time ]
> default
> Resets the policy to disallow ASN GW initiated re-authorization and sets the default values for CMAC key count and PMK grace time within the specific ASN GW service.
> max-cmac-key-count max_count
> Default: 100
> Configures the ASN Gateway to trigger the reauthorization on the basis of Cipher-based Message Authentication Code (CMAC) key counter. Once the CMAC counter crosses the configured value, the system initiates the reauthorization trigger.
> max_count is the CMAC key counter and must be an integer from 2 through 32768.
> pmk-grace-time grace_time
> Default: 60
> Configures the ASN Gateway to trigger the reauthorization on the basis of Pairwaise Master Key (PMK) key grace period. Once the configured PMK grace period exhausted the system initiates the reauthorization trigger.
> grace_time is the grace period in seconds to wait for Pairwaise Master Key (PMK) and must be an integer from 10 through 65335.
> allow
> Default: disabled
> Configures the ASN Gateway to initiate the reauthorization trigger to start the re-authentication based on two locally configured parameters; i.e. pmk-grace-time and cmac-key-count.

> Example
> The following command enforces the policy to trigger the reauthorization from the ASN GW:

> Product
> ASN GW
> Privilege

> default policy overload
> default
> Sets the traffic overload policy action to reject in this service.
> drop
> Default: disabled

> reject
> Default: enabled
> Specifies that the system processes new session request messages and responds with a reject message.
> Usage
> Congestion policies at the service-level can be configured for service. When congestion control functionality is enabled at service level, these policies dictate how services respond should the system detect that a congestion condition threshold has been crossed.
> Example
> The following command configures an overload policy of reject for this ASN GW service:
> policy overload reject
> ran-peer-map

> duration
> Default: 3
> Specifies the maximum allowable time for the ASN GW service to wait for a response from the BS before it (a) attempts to communicate with the BS again (if the system is configured to retry the BS) or (b) marks the BS as unreachable.
> duration is measured in seconds and can be configured to any integer value between 1 and 1,000.
> Usage
> Use this command in conjunction with the max-retransmission command in order to configure the ASN GW services behavior when it does not receive a response from a particular BS.
> Use the no retransmission-timeout command to delete a previously configured timeout value. If after deleting the lifetime setting you desire to return the lifetime parameter to its default setting, use the default retransmission-timeout command.
> The chassis is shipped from the factory with the retransmission timeout set to 3 seconds.
> Example
> The following command configures a retransmission timeout value of 5 seconds:
> retransmission-timeout 5

If enabled this command supports up to 4 hosts as an auxiliary connection. Accounting and UDR generation for such connection will be based on the primary connection with WiMAX CPE. To apply this facility to a subscriber you need to configure the ip address secondary-pool command in the Subscriber Configuration mode.
> Example
> The following command enables the multiple host support and instructs the ASN GW service to allow 3 IP hosts as auxiliary connections behind one CPE:
> secondary-ip-hosts 3
> The following command disable the multiple host support and instructs the ASN GW service not to allow auxiliary connections behind one CPE:
> default secondary-ip-host
> setup-timeout
> Configures the total amount of allowable time for the ASN GW service to setup a connection with the BS before it marks the BS as unreachable.
> Product

> default
> Sets the total timeout duration to 60 seconds to setup a connection with BS.
> duration
> Default: 60
> Specifies the maximum allowable time for the ASN GW service to setup the R6 connection with BS before marks the BS as unreachable.
> duration is measured in seconds and can be configured to any integer value between 1 and 100000.
> Usage
> Use this command to configure the maximum setup timeout duration to setup an R6 connection with BS. This command supersedes the duration set through the max-retransmission and retransmission-timeout commands for R6 connection.
> The chassis is shipped from the factory with the connection setup timeout duration to 60 seconds.
> Example
> The following command configures an ASN GW service to mark a BS after waiting for 100 seconds before marks it as dead or unreachable:
