Reference Resource: AAA_Server_Group
Key specifies the RADIUS server-group that it belongs to. Every RADIUS server must remain associated with the default AAA server group 'radius'. It would belong to the default family group 'radius' and optionally a user defined AAA server group Value specifies the priority of the RADIUS server in the associated AAA server group. A server with lower priority in a server group is reached out first. Servers with equal priority in a group will be reached out as follows: Those belonging to VRF where vrf_name appears alphabetically earlier than the others are reached out first. If that's a tie, servers with address appearing alphabetically earlier than the others is reached out first. If that too is a tie, servers with port_type appearing alphabetically earlier than the others is reached out first. If that too is a tie, servers with smaller UDP port are reached out first.
