Hi,
What is your connection manager of choice for either putty or teraterm?
I am currently using SuperPutty, I like it so far as it lets you save sessions on the right side and have multiple connections open in one window with tabs.
I have my devices connected to the console server, and I telnet to the console server to access the routers/switches that way.
