[j-nsp] 802.3ad trouble (part II)

[Jorn Ekkelenkamp]

Hi,

I've created an 802.3ad aggregated ethernet link between our M40 and a 
Nortel Passport 8110 using 2 fastethernet links (fe-0/1/3 and fe-1/1/3). 
  As you can see below the interface (ae1) comes up just fine, using 
both links.

This is the physical set-up we're using:
server --1000baseT--> nortel switch --802.3ad(2x100mbit)--> M40 --> 
"internet"

When I try to generate some traffic on ae1 by starting a few FTP 
transfers (multiple downloads at the same time, from different source 
addresses) interface fe-0/1/3 is not used AT ALL (see below). This 
results in a maximum speed of 100mbit for the whole ae1 interface.

Normally, I'd start looking at the config of my switch, but we've tried 
the same set-up with a HP ProCurve instead of the Nortel Passport, which 
produced the same results.

Has anyone seen something like this before?

All suggestions are more than welcome!

         device-count 2;
     }
     sonet {
         device-count 1;
     }
}
(the as0 interface is working just fine!)
