ppp can't run on this line

does anyone have a list of cisco vsa or av pairs? thanks! i just want to know whats out there and what i can use. is my problem.

i just started to setup authorization and now i can't get into my router by telnet.

all i did was this.

aaa athorization exec default group radius

and then applied

aaa athorization exec default to line vty 0 4

are you suppose to apply authorization to lines? but why is it saying ppp won't work? my debug says this

Re: ppp can't run on this line


You need to remove the following attribute in the profile of the user.

Framed-Protocol [7] 6 PPP [1]

If you are using the following attribute , router uses it for ppp authorization.

Here is the list of the av-pair.

these av-pairs can be used for radius as well as tacacs+.

Do let me know if you have any questions.
