I like the watchdog piece. I will set that on a couple of the worst
offending CPE and see what it does.

If you can't even telnet into them, they might be dead - have you
tried the watchdog?

I have thought of that, but it is not trivial with as many devices as we
have out, and it doesn't really seem to be OSPF as I can not even
MAC-telnet to the CPE from the CPE when it quits talking.

Scott,
Have you tried a FW upgrade? I had a few OSPF specific problems in v3
that all went away in v4.
I realize this isn't an OSPF specific problem but the current stable
release is 5.2 so there have probably been a lot of fixes implemented
since the release you are on.

I have about 3 APs that have customers with the same issue. All the
APs
in the network are MT ROS 3.30. CPEs are all MT, but various version,
predominately 2.9.51, 3.11, 3.30.
All APs are running OSPF and are on the backbone. At each tower
there is
also an OSPF area for the tower. All APs on the tower are in the tower
area. Most CPE on a tower are running OSPF and are in the tower area.
CPEs that are not at ROS 3.30 are running RIP to the tower.
Occasionally and at random issues, traffic will stop flowing
to/from one
or more customers. Usually going into the AP registration and dropping
the registration corrects the problem. Sometimes that does not
work, but
disabling the AP wireless interface for 5 seconds and the
re-enabling in
clears the problem.
It is probably not a hardware problem as all the hardware on the AP
end
of the worst offender has been replaced and made no difference.
One AP has 2 radio cards on board. Only one exhibits the problem. The
other never has. (I do not need advice on not putting two radio
cards on
the same card. This worked for a long time and only one site is
configured this way.) The other 2 that I know have the problem do not
have multiple radio cards on the routerboard.
Two of the offenders are running 10MHz channels, the third is
running b
only.
Processor utilization on all routerboards stays below 30%.
I am looking for some suggestions for things to look for. It seems
really odd that 3 of 60+ APs would have the same symptoms and the rest
never do.
