Cisco Equipment

Cisco equipment runs the IOS software and, while it’s become a common piece of equipment to find in an ISP, it does have some quirks of its own. Let’s take a look at a few.

    aaa new-model
    aaa authentication login default group radius local
    aaa authentication login localauth local
    aaa authentication ppp default if-needed group radius local
    aaa authorization exec default group radius local
    aaa authorization network default group radius local
    aaa accounting delay-start
    aaa accounting exec default start-stop group radius

    aaa new-model
    aaa authentication ppp radppp if-needed radius
    aaa authorization network radius none
    aaa accounting network wait-start radius
    aaa accounting network wait radius
    radius-server timeout 3

aaa accounting update newinfo
