AS5800 and Idle-Timeout Issue Matt 12-01-05

Hi,
I have two AS5800 access servers. They seem to interpret Idle-Timeout
and Ascend-Idle-Limit as Session-Limit or something like that.

If I set the Idle-Timeout to 30 minutes, people seem to get kicked off
line after 30 minutes with a reason of "Idle-Timeout" even if they were
downloading a file.

Any thoughts?


My config for the groups and async is:

interface Group-Async0
no ip address
encapsulation slip
no group-range
!
interface Group-Async1
ip unnumbered FastEthernet0/1/0
ip access-group 105 in
ip access-group 105 out
encapsulation ppp
dialer in-band
dialer idle-timeout 0
async dynamic address
async dynamic routing
async mode interactive
peer default ip address pool pool0 pool1 pool2 pool3
compress mppc
ppp pfc remote ignore
ppp acfc remote ignore
ppp authentication chap pap
ppp multilink
group-range 1/6/00 1/11/143
!
interface Dialer1
ip unnumbered FastEthernet0/1/0
encapsulation ppp
no ip route-cache
no ip mroute-cache
dialer in-band
dialer idle-timeout 0
no peer default ip address
no fair-queue
ppp authentication chap pap
ppp multilink
!

Actually it seems like it IS working....
However, it seems like the AS5800 is not reset the idle timeout when
someone passes data!!! Any thoughts on this one?!?!

If you want any traffic to be considered as interesting, and hence to
reset your idle timeout, then you would need to configure a dialer-group
on the relevant interface (which I presume is group-async1, as there is
no dialer rotary or dialer pool-member configured to bind it to dialer1),
which dialer-group should point to a dialer-list.

Cheers,

Aaron

Aaron,
Thanks I'm about to check this out today, as it's working on one of our
AS5800's but not the other. How can I go about setting an amount of
data to be "interesting" so that just leaving mail open doesn't keep a
connection up?

Well,
The configuration on both of our access servers look exactly the same...
hrmmm =\
