hey all,
I am trying to extablish a telnet with a swich The switch responds with a trying... and then open... no prompt for password or user name is displayed
but anything that you typed will be echo back. I tried the "no service tcp-small-servers" did not work..appreciate the help
I can cosole into the switch no problem, but I can not telnet from the switch either,,I get % Connection aborted

try this: This will allow ONLY telnet in and set a password of cisco. Youse Login local if you want to have it use a username and password, however you must define that useraname and password.
line vty 0 15
password cisco
login
transport input telnet

Hi Jay,
Can you post the configuration of the switch so we can assist further.

Hi Jay,
I can see that you are using TACACS. Here are the questions for you
1) Is your switch able to ping to the TACACS server?
2) If yes to question 1, did you add the switch into the TACACS server?
HTH,

If TACAS is unavailable you wont be able to get in. You can set it up to use TACAS and if tacas is unavailable use the login password.
aaa authentication login VTY group tacacs+ line
line vty 0 15
login authentication VTY
That should get you in with the speccified line password under line vty 0 15

I compared this line for line from our other switches and it is the same no differences..
these are from other switches
line vty 0 4
exec-timeout 30 0
full-help
transport input telnet
transport output all
line vty 5 15
exec-timeout 30 0
full-help
transport input telnet
transport output all
and they work fine..

Shouldn't this line be
aaa authentication login default group tacacs+ line
"aaa authentication login default group tacacs+ enable" which seems to be calling the enable password for login instead of the line or local username password. What are you using for login the local username or the line vty password , both are configured.

yes you are correct..both are configured..we are using the tac for login..the local username was there before and it needs to be cleaned up..it does not appear to be a tacac issue..when we telnet to the switch it appears to connect nothing appears on the screen except the curser..it almost looks like a hyperterminal connection when the speed is wrong..
