The Catalyst 6000, 5000, and 4000 have SSH support. They are VERY expensive. 1000€ mini.
Also n many old Cisco routers, you have acces to an embedded unix-like environment, on the minimum it's BusyBox-like, and that allows you for installation and use of SSH. Mind you, this IS tricky. The C 7400 is the most dumb and un-intuitive machine I ever programmed.
Can i ask, why not the simple and cheap ATX-based linux box w/ a couple of NICs ? It allows you to fully configurate your services, but also comes pre-installed ! I mean a vanilla RedHat *is* a router, and a good one.
