Dell S4048 stacking/management question

Got a question around 2 stacked S4048's and management access. So I have an ip address on management 1/1, well call it 10.50.1.10/24 and then a management route that is "management route 0.0.0.0/0 ManagementEthernet" We also use Radius/Tacacs for logging on. When node is the active node all works as expected however when I failover to the secondary node "redundancy force-failover stack-unit" it all goes a bit wrong. 1. It takes about 20 failed pings before the management ip address starts responding - this is wrong it is too long 2. When you attempt to login it will not process the Radius/Tacacs but you have to login with a local account - This is also wrong 3. When you do pass the credentials it comes up in standby and you have to use the "telnet-peer-stack-unit" to access the active node and then it still wont process the Radius/Tacacs login but you have to login locally - This too is wrong. What is needed to fix these issues ?

Hi,

What version is the firmware at? Can you check to see if the hardware watchdog is enabled?

remote-exec <unit id> wdogctl

it should show mmcx0, 60 second period

Ok, in that case can you see if there are any errors in the logs around the failover time?
