Figure 237. Signaling Survivability via alternate LAN

sig_surv_altlan_scenario-2.jpg
The configuration in the OpenScape 4000 switch is realized as follows:
  • If signaling survivability via alternate LAN will be used, UDP must be configured for HSR signaling for the access point/OpenScape 4000 SoftGate.

Access Point (direct link):
ADD-UCSU:UNIT=AP,LTG=1,LTU=17,LTPARTNO="Q2324-X10 ",SRCGRP=1,FRM­

OpenScape 4000 SoftGate (networked link):

UC=0,DTR=0,CNTRYCD=0,SIGMODE=HSRUDP;
IMPORTANT:
When switching from HSRTCP to HSRUDP or vice versa an EXEC-USSU:TYPE=UPDATAP,LTU=<number>; must be executed. Existing connections are cleared down without further warning!
INFO:
SIPCO parameter SURVNET has no effect on the feature Signaling Survivability via alternate LAN, however AMO APRT requires an entry to allow it to add a router.
  • Announce the survivability routers in the system

Configuration Management > System Data > IPDA > IPDA Signaling Survivability Router
Click Search, enter or change the router number and address on the Router Data tab, then Save.

ADD-APRT:TYPE=SURV,CONF=ROUTER,ROUTERNO=1,LSADDR=172.15.3.202;
Router 1 from the example in Figure 16 “Signaling Survivability via alternate LAN” is thus configured.
  • Assign the access points to the survivability routers
assistant-2.gif
Configuration Management > System Data > IPDA > IPDA Access Point
Click Search, set the desired router number on the General tab under signaling survivability and Save.
