I realy belive I've missed something. When the 3500 &2950 switches loose conection to the tacacs+server I cannot get access. The switch is'nt giving me the option to use the fallback. The following is a selection og the configs.
logging buffered 10000 debugging
no logging console
aaa new-model
aaa authentication login default group tacacs+
aaa authentication login no_tacacs enable
aaa authentication ppp default group tacacs+
aaa authorization exec default group tacacs+
aaa authorization network default group tacacs+
aaa accounting exec default start-stop group tacacs+
aaa accounting network default start-stop group tacacs+
and at the vty line -
line vty 0 4
password whatever
line vty 5 15
password whatever1
What am I missing ? Thanks
