Re: how to login from aux of router to console of a switch

aaa authentication login login-auth-none none

line aux 0

no vacant-message

login authentication login-auth-none

modem DTR-active

special-character-bits 8

no exec

transport input telnet

escape-character NONE

stopbits 1

Then do a "sho line" to find the line number of your AUX port. You can now telnet to the IP of any interface on your router on port [2000 + line # of AUX] and gain access to the switch.

For example, if a Loopback IP on your router is 10.10.10.10 and the line number of the AUX port is 161, you can execute "telnet 10.10.10.10 2161"

Hope this is what you're looking for...

you would need to setup both AUX as SLIP interfaces. (this requires IP connectivity enabled on the aux ports)

haven't tried it but if both are setup as SLIP, should be able to communicate via IP

see this link for more info:

additional async/slip commands can be found here:
