Configuring the IUA Link

Configuring the IUA Link

This topic describes how to configure the IUA link for signaling transmission between the Access node and MGC in the VoIP ISDN service.

Context

  • Simple Control Transmission Protocol (SCTP) is a connection-oriented protocol. Its most fundamental function is to provide reliable transmission for interaction messages between the Access node and MGC. The SCTP protocol implements services based on the association between two SCTP endpoints. SCTP can be regarded as a transmission layer. Its upper layer is called SCTP subscriber, and its lower layer is the IP network.
  • The IUA link is the carrier of the interaction signaling between the Access node and MGC.

Adding an IUA Link Set

This topic describes how to add an IUA link set. When configuring the VoIP ISDN service, you need to configure the IUA link to carry the Q.931 call signaling. Before adding an IUA link, you must add a corresponding link set. Otherwise, the link cannot be added.

Context

  • The system supports the configuration of a maximum of IUA link sets.
  • After a link set is configured successfully, it is in the deactivated state by default.

Procedure

  1. In global config mode, run the command sigtran to enter Sigtran mode.
  2. Run the iua-linkset add command to add an IUA link set.
  3. You can run the display iua-linkset attribute command to check whether the configured IUA link set information is the same as the data plan.

Example

Assume that the link set ID is 0, working mode of the link set is active/standby mode, pending duration is 20s, prefix of the IID is b/, IID generation mode is using the binary value that is automatically generated in ffsspp mode, namely, parameter 2. To add such an IUA link set, do as follows:

huawei(config)#sigtran
huawei(config-sigtran)#iua-linkset add 0 trafficmode override pendingtime 20 iid-map 2 
braprefix b/
huawei(config-sigtran)#display iua-linkset attribute
{ <cr>|linksetno<L> }:                                                          
                                                                                
  Command:                                                                      
          display iua-linkset attribute                                         
----------------------------------------------------------                      
  LinksetNo             :0                                                      
  PendingTime           :20                                                     
  TrafficMode           :override                                               
  C/S-Mode              :server                                                 
  IID-Type              :integer                                                
  IID-Map               :2                                                      
  BRA IID-Prefix        :b/                                                     
  BRA IID-Suffix        :-

Adding an IUA Link

This topic describes how to add an IUA link. After the link set is added, you can add an IUA link to carry the Q.931 call signaling for the ISDN user.

Prerequisites

The IUA link set must be added.

Context

  • Make sure that a minimum of one item in the local port ID, local IP address, remote port ID, and remote IP address of a link is different from the corresponding item of other links.
  • Only two links can be configured in the same link set. In addition, the local IP addresses of the two links must be the same.

Procedure

  1. (This step is not required if the command line interface is already in the Sigtran mode.) In global config mode, run the sigtran command to enter the Sigtran mode.
  2. Run the iua-link add command to add an IUA link.
  3. You can run the display iua-link attribute command to check whether the configured IUA link information is the same as the data plan.

Example

Assume that the link ID is 0, link set ID is 0, local port ID is 1402, local IP address is 10.10.10.10, remote port ID is 1404, and remote IP address 1 is 10.10.10.20. To add such a link, do as follows:

huawei(config)#sigtran
huawei(config-sigtran)#iua-link add 0 0 1402 10.10.10.10 1404 10.10.10.20
huawei(config-sigtran)#display iua-link attribute
{ <cr>|linkno<L> }:
  
  Command:
          display iua-link attribute
  ----------------------------------------------------------------------
  LinkNo                :  0
  LinksetNo             :  0
  Local port            :  1402
  Local IP address      :  10.10.10.10
  Remote port           :  1404
  Remote IP address     :  10.10.10.20
  Remote IP address 2   :  -
  Priority              :  0
