PPP CHAP re-authentication timer , detectable ?

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
