Configuring the Media and Signaling IP Address Pools

The media IP address pool defines all media IP addresses that can be used by the AG, and the signaling IP address pool defines all signaling IP addresses that can be used by the AG.

Prerequisites

The IP address of the Layer 3 interface of the media and signaling upstream VLAN must be configured. For details about how to configure the IP address, see Configuring the Upstream VLAN Interface.

Context

• The media IP address and the signaling IP address for the MG interface must be selected from the IP address pools configured here.
• The signaling IP address pool is used to store the IP addresses of the MG interfaces, and the media IP address pool is used to store the IP addresses of the media streams controlled by the signaling.
• The media IP address pool and the signaling IP address pool can be the same. Similarly, the media IP address and the signaling IP address can be the same.
  NOTICE:

  The MGCP interface on the MA5680T/MA5683T/MA5608T does not support the isolation of media streams and signaling flows. Therefore, when the MGCP protocol is used, the media IP address pool and the signaling IP address pool must be the same. When the H.248 or SIP protocol is used, the media IP address pool and the signaling IP address pool can be the same or different.

Procedure

1. Run the voip command to enter the VoIP mode.
2. Configure the media IP address pool.
   1. Run the ip address media command to add the media IP address to the media IP address pool. The media IP address needs to be selected from the IP addresses of the Layer 3 interface of the media and signaling upstream VLAN.
      
      
   2. Run the display ip address media command to check whether the media IP address pool is the same as that in the data plan.
3. Configure the signaling IP address pool.
   1. Run the ip address signaling command to add the signaling IP address to the signaling IP address pool. The signaling IP address needs to be selected from the IP addresses of the Layer 3 interface of the media and signaling upstream VLAN.
      
      
   2. Run the display ip address signaling command to check whether the signaling IP address pool is the same as that in the data plan.

Example

To add IP addresses 10.13.4.116/16 and 10.13.4.117/16 of Layer 3 interfaces of the media and signaling upstream VLAN to the media IP address pool and the signaling IP address pool respectively, do as follows:

huawei(config)#voip
huawei(config-voip)#ip address media 10.13.4.116 10.13.0.1
huawei(config-voip)#ip address media 10.13.4.117 10.13.0.1
huawei(config-voip)#ip address signaling 10.13.4.116
huawei(config-voip)#ip address signaling 10.13.4.117
huawei(config-voip)#display ip address media               
  Media:               
  IP Address...........: 10.13.4.116

  Gateway..............: 10.13.0.1     
  MAC Address..........: 00-E0-FC-AF-91-33      
 
  IP Address...........: 10.13.4.117

  Gateway..............: 10.13.0.1           
  MAC Address..........: 00-E0-FC-AF-91-33       
huawei(config-voip)#display ip address signaling                
  Signaling:                                                                    
  IP Address...........: 10.13.4.116                                            
  Subnet Mask..........: 255.255.0.0                                            
  MAC Address..........: 00-E0-FC-AF-91-33                                      
                                                                                
  IP Address...........: 10.13.4.117                                            
  Subnet Mask..........: 255.255.0.0                                            

  MAC Address..........: 00-E0-FC-AF-91-33
