In this section:
Release SBC 8.1 onwards, support is added to the virtual SBC SWe, I-SBC and D-SBC for gateway-to-gateway signaling between the SBCs, and between the SBC and the GSX9000 in an N:1 model when using an external PSX.
Additional functionality:
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:
The SBC 5210 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.
(This ability does not apply to the SBC 5110 and 5400 systems which have only two physical media ports. IP interfaces from the two physical ports may be configured within the same IP Interface Groups without restrictions.)
For complete details, refer to Configuring IP Interface Groups and Interfaces.
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
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.
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
Disable the internal policy server and configure an external policy server because 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
The following example shows gateway-gateway signaling configuration on an I-SBC/D-SBC:
