Thanks for the detailed explanation. Only thing that i have to mention is, please don't use the Microsoft Sam voice anymore! (it makes you fall asleep).
I have a question what if on both gateways different ccp mode(multicast and broadcast).what is the output of cphaprob stat and cphaprob -a if on both gateways
Hi Arun, In case of one member ccp mode set to broadcast and the other to multicast, in version R80.20 and above, the output is below: Member A: ========= [Expert@R80.20_GW1:0]# cphaprob stat Cluster Mode: High Availability (Active Up) with IGMP Membership ID Unique Address Assigned Load State Name 1 (local) 12.0.0.1 0% STANDBY R80.20_GW1 2 12.0.0.2 100% ACTIVE R80.20_GW2 Active PNOTEs: None Last member state change event: Event Code: CLUS-114802 State change: DOWN -> STANDBY Reason for state change: There is already an ACTIVE member in the cluster (member 2) Event time: Tue Feb 4 15:18:30 2020 Cluster failover count: Failover counter: 0 Time of counter reset: Fri Jan 31 10:12:11 2020 (reboot) [Expert@R80.20_GW1:0]# [Expert@R80.20_GW1:0]# cphaprob -a if CCP mode: Manual (Multicast) Required interfaces: 3 Required secured interfaces: 1 eth0 Non-Monitored non sync(non secured) eth1 UP non sync(non secured), multicast eth2 UP sync(secured), multicast eth3 UP non sync(non secured), multicast Virtual cluster interfaces: 2 eth1 10.0.1.150 eth3 13.0.0.10 Member B: ========= [Expert@R80.20_GW2:0]# cphaprob stat Cluster Mode: High Availability (Active Up) with IGMP Membership ID Unique Address Assigned Load State Name 1 12.0.0.1 0% STANDBY R80.20_GW1 2 (local) 12.0.0.2 100% ACTIVE R80.20_GW2 Active PNOTEs: None Last member state change event: Event Code: CLUS-114904 State change: ACTIVE(!) -> ACTIVE Reason for state change: Reason for ACTIVE! alert has been resolved Event time: Tue Feb 4 15:18:30 2020 Cluster failover count: Failover counter: 0 Time of counter reset: Fri Jan 31 10:12:11 2020 (reboot) [Expert@R80.20_GW2:0]# [Expert@R80.20_GW2:0]# cphaprob -a if CCP mode: Manual (Broadcast) Required interfaces: 3 Required secured interfaces: 1 eth0 Non-Monitored non sync(non secured) eth1 UP non sync(non secured), broadcast eth2 UP sync(secured), broadcast eth3 UP non sync(non secured), broadcast Virtual cluster interfaces: 2 eth1 10.0.1.150 eth3 13.0.0.10 Best Regards
