Hi all I am playing in the lab with a Cat2900XL (IOS12.05.2) XU) 24 ports. I am a little confused with IOSs and command lists from Cisco site. Cisco web site says that Catalyst 2900 and 3500 XL have the same IOS. So I read this page to see the complete list of command. It is strange that the page show me the command tacacs-server last-resort here : http://www.cisco.com/univercd/cc/td/doc/product/lan/c2900xl/29_35xu/cmdref/m acrcli.htm#xtocid24729124 but the Cat2900 seems to do not know about the command. Any explanation for that ? Thanks in advance. Cristian Ps. I would like to know the way to find the complete set of commands for a specific device on Cisco site. Could anybody help me ?
