I have a Catalyst 4510R that refuses the connection. I have tried Tera Term and a windows command line telnet and neither works. I don't get a username or password prompt.
I suspect that the vty line needs the login command. Strange thing is it used to work, not sure why someone would take the login command off.
No TACACS commands loaded and only two aaa commands.
All passwords are the same except the line password.
There is also a error message about sticky arp?
aaa authentication login default local
enable password 7 zzzz
username ABC password 7 zzzz
sh run | beg line
line con 0
password 7 xyxy
line vty 0 4
password 7 zzzz
