I think PPP with CHAP has an interval or periodic timer that triggers a re-authentication.
I cannot find a timer setting to set the interval.
Neither can i find a show command that will show me the timer.
If this is a randomized timer, then it is clear that it is not showing these timers, but..
How would i be able to DETECT when a re-authentication has happened ? How long should i monitor a CPE to check if a CHAP re-authentication has happened ?
I am using these debugs:
PPP authentication debugging
PPP protocol negotiation debugging
PPPoE protocol events debugging
but has not seen a CHAP event yet.
The setup is a 1006 as BRAS with SB-radius, 867VAE and other Cisco DSL clients using PPPoE.
So my Q's;
- is CHAP re-authentication detectable ? how ? what average timers ?
- Is the interval settable ? how
