Chadd,

   Did that fix your problem or do you still have issues?

Merry Christmas!

Well I did a bit of searching on the trango support forums and found a
thread of someone with a similar problem. Trango support made a
recommendation to turn off the maclist filter off on the RU. I went a head
and turned it off on the RU's, telnet in and issue maclist filter off
command. I did this last night sometime and have not had any issues as of
yet. Since last week sometime I was having to reboot the BH's twice a day or
more. I will see what happens with it and if this doesn't do it I will let
you guys know.

Funny thing about this is that about a week ago I was thinking to myself
damn those link 10's have ran good the last few years. I was an early
adopter of the link 10 and had nothing but issues with them for the first 6
months or so after release, I felt like a beta tester. Once they fixed
software bugs though they have ran well, until now that is.

Problems like this make you realize how quickly and unexpectedly things can
take a crap on you with little or no changes to your network.

Thanks again for the help.

 Chadd,
 
   That is a Trango command and it does turn arp off. I have both worlds
 here
 - - bridged and routed and I have never had any of my TLink 10's to do
 that
 to me. I am not saying that's not your problem - I am just saying I have
 never had that issue. We have many more than 300 traversing Tlink10
 backhauls today - - -
 
 What firmware are you running? Is there a certain time of the day things
 go
 awry? A certain temp? Is there a pps correlation? What is each Tlink
 plugged
 in to?

 Chadd,
 
 We experienced similar issues when our network was entirely bridged.  The
 root of the problem turned out to be the ARP table in the Trangos we were
 using as are primary BHs.
 
 Once the number of clients behind the Trangos exceeded a certain limit the
 ARP table gets corrupted.  Trango does not have a fix for this issue.
 
 As a temporary fix you can set up a script to reset the ARP table in the
 Trangos on a regular basis.  The command line for the 5800 and 5830 units
 is
 maclist reset.
 
 We have moved to a mostly routed network which has greatly reduced the
 number of MAC addresses seen by the Trangos.  This fixed the problem.

 The strange thing that not all the radios on the segment will have

 have checked the BH links when things start going haywire and can't seem

Sounds like this could be it.

The backhauls are Trango link 10's do you happen to remember what the ARP
limit was that you were having problems with?

Chadd,

We experienced similar issues when our network was entirely bridged.  The
root of the problem turned out to be the ARP table in the Trangos we were
using as are primary BHs.

Once the number of clients behind the Trangos exceeded a certain limit the
ARP table gets corrupted.  Trango does not have a fix for this issue.

As a temporary fix you can set up a script to reset the ARP table in the
Trangos on a regular basis.  The command line for the 5800 and 5830 units is
maclist reset.

We have moved to a mostly routed network which has greatly reduced the
number of MAC addresses seen by the Trangos.  This fixed the problem.

Subject: [WISPA] Strange network issues crosspost

Sorry to cross post this guys but I am looking for suggestions and wasn't
sure if everyone is on both lists.


I have been having an intermittent problem the last few days. A few of my
AP's and CPE's will stop responding. These are a mixture of brands, Trango,
MT, Brilan, they are on different network segments, different frequencies. 

The strange thing that not all the radios on the segment will have problems
only some, and even more odd is that an AP can stop responding but you can
still access some of the CPE's associated with it and they will pass traffic
fine. In any case a reboot of the backhaul that feeds each individual
segment will bring them all back up again for a random amount of time. I
have checked the BH links when things start going haywire and can't seem to
find any issues, no oddball traffic, packets per second seem fine. Also my
ARP tables seem to be fine when this happens, but I haven't tried to flush
my ARP when I have the issue.

Everything is currently and has been for 4 yrs bridged and it is getting
to the point where I need to break down and start setting up routing at each
of my POPs. I had thought it may be a bridge loop, but if that was the case
I wouldn't think the segment would operate fine for a while after a Backhaul
reboot.

I am looking for suggestions of other things I may/should be checking and or
looking at.

Thanks,
Chadd

Mac,

Is this a trango command? I don't remember there being an arp command in
the link10's

Thanks,
Chadd

Mac,

We tried that but it didn't totally resolve the issue.  Chadd, I would guess
it was around 100.
