If the cluster management IP address is not in the list of failover network unicast addresses, the blade management IP addresses in the unicast mesh will not be able to receive failover messages from peer devices.
The blade management IP addresses in the failover network unicast mesh stop functioning: [root@VIP2200-R75-S5:/S1-green-P::Standby:In Sync] config # tmctl -w 200 -S sod_tg_conn_stat entry_key local_failover_addr remote_device_name pkts_received transitions last_msg status ----------------------------- ------------------- ------------------------------ ------------- ----------- ---------- ------ 10.200.75.8->10.10.10.1:1026 10.10.10.1:1026 VIP2200-R75-S8.sin.pslab.local 3249 3 1555399271 1 10.200.75.8->10.200.75.3:1026 10.200.75.3:1026 VIP2200-R75-S8.sin.pslab.local 0 1 0 0 <-- 10.200.75.8->10.200.75.4:1026 10.200.75.4:1026 VIP2200-R75-S8.sin.pslab.local 0 1 0 0 <--
-- VIPRION chassis or vCMP guest on a VIPRION chassis. -- Per-blade management IP addresses listed in the failover network unicast mesh. -- No cluster management IP address listed.
You can add an explicit management IP firewall rule to allow this traffic: tmsh modify security firewall management-ip-rules rules add { accept_udp_1026 { place-before first ip-protocol udp destination { ports add { 1026 } } action accept } } This will add a firewall policy so port 1026 is no longer locked down, and the blade management IP addresses in the unicast mesh should begin to function properly.
