Why does it use TTY 66 and not TTY 1 like all the rest.</P> Sun, 10 Mar 2019 14:24:12 GMT https://community.cisco.com/t5/network-access-control/telneting-from-one-switch-to-another-switch/m-p/147256#M436205 dbnorton 2019-03-10T14:24:12Z Re: Telneting from One Switch to another Switch https://community.cisco.com/t5/network-access-control/telneting-from-one-switch-to-another-switch/m-p/147257#M436206 <HTML><HEAD></HEAD><BODY><P>As far as I know on a Switch it should be a VTY, surprising to see you mentioning it as TTY.
