Which one of the Catalyst 2950 series support SSH crypto and port mirroring? or which IOS image supports these two features that I`m able to load into 2950 switch?thanks

I have a CAT2924XL switch with IOS:c2900xl-c3h2s-mz.120-5.wc9a.bin, I need to add it to TACACS+ running server. Does this IOS or any other support TACACS+(SSH)for this witch or it`s too old?

I need to add a Cisco 2900XL switch to TACACS+ server. Is there documentation for this approach.Thanks

Is there a tool that can test P2P T1 connection failure, specifically which end is failed???
