Re: Orcon APE connection woes

      We saw this same problem for a while, and they told us the other thing.

It eventually turned out that they hadn't actually locked the port on the
clear IPe switch to 10/half, and it was totally failling to correctly
autonegotiate.

Once they forced their end, it all got a lot happier... This took 3 days
of them telling us that it was our end that was at fault.

Hmm
we have forced full-duplex and turned off auto-negotiation on our Catalyst
5000 switch - but we have also tried all the other settings possible.
Clear have told us to set it to 10Mbps Full-Duplex - so that's what it is at
present.

I had some problems recently that were marginally similar.  Although I had
the speed and duplex settings configured, it didn't come right until I
turned off auto negotiation as well (eg no negotiation or something along
those lines).
No idea if it's your problem - just seems familiar.
Good luck :-)

Hi there everyone
Orcon has just had a 10Mbit IPExpress connection to APE
completed, and I
have been fighting with it all day.
If we ping anyone on APE, then we get around 2/3's of the
pings through, and
1/3 are dropped.
This happens in a pattern of 1/3 drop, 2/3 get through.
I talked with Clear and they said that it could be the
IPExpress connection
re-negotiating because of what is on our end, so we have been
playing with
the settings on our Catalyst 5000 switch - we have forced the
port to our
IPExpress connection full duplex / half duplex / 100mb / 10mb
but they all
seem to give the same results.
Clear has advised us to set our equipment to 10Mbit full
duplex - so that's
what it is at present.
The connection from IPExpress is then VLan'd from our
Catalyst switch into
our core Cisco 7505 router.
A ping report of 300 pings to ihug.ape.net.nz looks like this
---------------------------------------------------
ORCON7505#ping
Protocol [ip]:
Target IP address: ihug.ape.net.nz

Sending 300, 100-byte ICMP Echos to 192.203.154.36, timeout
is 2 seconds:
........!!!!!!!!!!!!!!!!!!!!!..........!!!!!!!!!!!!!!!!..........!!!!!

Success rate is 65 percent (197/300), round-trip min/avg/max
= 1/3/24 ms
--------------------------------------------------
Can anyone shed any light on this?
Is this related the the spanning tree problems that have been
happening up
at APE recently?
Or should we be hassling Clear about the service.....
Cheers
