procurve 2424 vlan and bridge
My setup is as follows:
vlan 1 consists of port 1, 7 and 8.
vlan 2 consists of the rest.
(None of these vlans are the default 1)
I have my internet connection on port 1, and on port 7 i have my bridge (transparent firewall running linux) wich is connected to the other vlan.
internet > vlan1 > bridge > vlan2 = packetloss
Everything works like a charm if i do like this:
internet > another switch > bridge > vlan2
so it shouldn't be the bridge making the fuss.
stp not enabled, no trunking.
Any ideas?

Re: procurve 2424 vlan and bridge
port counters look normal. no Errors Rx, no Drops Tx.
I tried every setting possible concearning half/full duplex.
The internet is distributed from another procurve with 10baseT-FD, and that is what Port status on my switch is indicating, I tried setting that port and every other port connected to the bridge to 10baseT-FD including the 2 ports on the bridge, that had no effect.
Noticed today that if I replace what was mentioned above as vlan2 (my dmz) with another switch I end up with no packetloss
In other words:
internet > vlan1 > bridge > anotherswitch
It really feels like I am stumbling in the dark.

Re: procurve 2424 vlan and bridge
Do the losses appear to be related to a certain packet size? i.e. do small packets go through fine but packets above a certain size tend to have losses?

Re: procurve 2424 vlan and bridge
C.09.22, ROM C.06.01
I played around with diffrent sized icmp-packets and it doesnt seem to make any difference.
all though I have seen some improvement down to *only* 20% packetloss but I haven't yet found the reason to that, seems to random.

Re: procurve 2424 vlan and bridge
dit you check if the 2224 got one unique mac@ table for all his vlans of one for each ?. If he has one unique table he can't decide if a computer is one one side or on the other side of the bridge. The same probleme occured with intel 460T switches. Try to use a 2824 if possible.
