As long as at least one mgmt interface is up (i'm using a virtual-ip for the mgmt interfaces), tacacs communication should happen through the out-of-band mgmt interfaces. If all mgmt interfaces are down, then tacacs communication should happen through an inband interface.
Guess what! There seems to be an issue with the above scenario, because in the 2nd case (where all mgmt interfaces are down) tacacs communication doesn't happen at all. Looking at the debugs, it's like the router isn't even trying to use the second (global) tacacs group. This has already been opened as SR (according to tac this should work, so let's hope it's just a bug), so i'm waiting for developers' feedback right now.
In order to overcome the above problem, i thought of using different vty templates, each one with a different access method.
In IOS you can have the following vty configuration and then access vtys 11-15 by either using "telnet x.x.x.x 3001" or "telnet x.x.x.x 2000+y" where y is the tty number displayed by using the command "show line".
