In this section:

From release SBC 8.1 onwards, gateway-to-gateway signaling support is added to the SBC SWe, I-SBC and D-SBC between the SBCs and between the SBC and the GSX9000 in an N:1 model when using an external PSX.

Additional functionality:

  • The SBC SWe supports IP address-based configurations.
  • The SBC Cloud supports IP address configurations using metavariables for gateway signaling.

The SBC uses gateway signaling to communicate between the SBC/GSX system and the SBC SWe cloud and between the two SBC cloud platforms when using an external PSX.


GW signaling port limitations:

  • You must create the GW signaling port under the default address context and within the 'defaultSigZone.'
  • A GW signaling port must use an ID of "1".


Note

The SBC 5400 and SBC 7000 systems support creating IP Interface Groups containing sets of IP interfaces that are not "processor friendly" (i.e. carried on physical Ethernet ports served by separate processors). However, restrictions exist regarding the usage of such Interface Groups.

For complete details, refer to Configuring IP Interface Groups and Interfaces.

  1. Configure an IP interface with an IPv6 address:

    % set addressContext default ipInterfaceGroup LIFG1 ipInterface LIF_1 ceName SBX1-1 portName pkt0 ipAddress 10.32.113.1 prefix 16 altIpAddress fc00::3200:0:0:113:1 altPrefix 64

  2. Configure an IPv6 signaling port under the default address context and zone:

    % set addressContext default zone defaultSigZone gwSigPort 1 ipAddress fc00::3200:0:0:113:99 ipInterfaceGroupName LIFG1 state enabled mode inService

    The configuration fails if the specified IP address is set to 'loopback', 'link local' or 'unspecified', or is an IPv4-mapped IPv6 address.

  3. Configure a GW trunk group under the default address context and zone with an ingress prefix on the egress gateway:

    % set addressContext default zone defaultSigZone gwTrunkGroup GW_TG state enabled mode inService ingressIpPrefix fc00::3200:0:0:112:99 128

  4. Disable the internal policy server and configure an external policy server. The SBC must use an external policy server to run GW-GW calls.

    % set system policyServer localServer PSX_LOCAL_SERVER mode outOfService state disabled 
% set system policyServer remoteServer PSX_REMOTE_SERVER ipAddress 10.31.240.106 mode active state enabled

Configure an SNMP target to view the new IPv6 GW link traps:

% set oam snmp trapTarget trapDest ipAddress 10.31.240.108 port 162 state enabled trapType v2

GW-GW Signaling Configuration Example
