IP Interface Group - IP Interface - Alt Media IP Addresses

A maximum of 254 IP addresses are configurable on each LIF for IPv4 and/or IPv6 addresses. Any combination of IPv4/IPv6 is allowed and applies to all supported protocols (SIP, H.323, GW-GW).

A total of 4,096 IP Addresses are supported. One example of assigning 4,096 IP addresses is to assign 16 IP addresses (one primary IP Address, one Alternate IP Address and 14 Alternate Media IP Addresses) to each of 254 interfaces. Another possible combination is to assign eight IP Addresses (one Primary IP Address and seven Alternate Media IP Addresses) to each of the 254 interfaces. In the extreme case, each of the 4,096 interfaces are assigned a single primary IP address. Please note that most user configurations will not need to use 4,096 IP addresses.

Alternate Media IP’s are chosen based on Round Robin method (e.g. the first call uses the primary IP and port, the second call uses the first configured alternate Media IP and port, the third call uses the second configured alternate Media IP, etc.). Each alternate Media IP must be unique across all interfaces in the same addressContext. However, the IPs may overlap between SIP, H.323 or Gateway signaling addresses in the same Address Context.

The following constraints apply:

• An IPv4/IPv6 alternate media IP address is only allowed if a primary IPv4/IPv6 address exists.
• An alternate media IP address must be in the same network as the primary media address (of the same IP version).
• An alternate media IP address can only be deleted if the IP interface is in state disabled. However, it may be added while the IP interface is enabled and in-service.

To View Alt Media IP Addresses

On the SBC main screen, navigate to All > Address Context > IP Interface Group > IP Interface > Alt Media IP Addresses.

The Alt Media IP Addresses can be checked for each Address Context, IP Interface Group, and IP Interface or for all the Address Contexts, IP Interface Groups, and IP Interfaces created. Use the drop-down box to select the desired Address Contexts, IP Interface Group, and IP Interface.
