RTR/SAA MD5 authentication on 2950

[barzog]

On catalyst 2950 with c2950-i6q4l2-mz.121-22.EA1.bin we have command "rtr key-chain <name of key-chain>". But I can't find command "key chain <name of key-chain" for configuring password key-string for RTR/SAA authentication. So, how can I uses RTR/SAA with MD5 authentication between catalyst 2950 and 3550?

You can enter " key-chain key" configuration submode from key-chain configuration mode, use the key command and use key-chain key configuration mode to configure a specific authentication key in a key-chain.I feel that below link provide more specific related to configuring KEY-CHAIN command.

c2950-77#conf t

Enter configuration commands, one per line. End with CNTL/Z.

c2950-77(config)#key chain

It seems that catalyst simple does not known all "key" commands. But it know "rtr key-chain" commands. Why such inconsistency?
