both nodes on Windows Server 2016 last update on june 2021
We have a Windows Failover Cluster involving node DLT-DBDR01 and DLT-DB02
Network Interface model HPE 331li, teamed via ServerManager
servers on VLAN1001, clients on VLAN1003
we do a role (10.10.1.19) failover from node DLT-DBDR01 to DLT-DB02, and after capturing packets on the CISCO switch, we don't see any GARP request from DLT-DBDR01
so the role is unreachable from the VLAN1003
we then do a clear of the ARP table, and the role starts to be reachable.
oddly enough, if we then do a failback, the request appears on the packet capture
I thought this was a switch issue, but why the failback doesn't need an ARP table clear?
Thanks in advance,
