Hi Folks,
Put a bridge between 2 CISCO devices (router and a switch) where the switch is the trunk end of 2 VLANs.
Packets work up to a size of 1470. Any bigger appear to be getting dropped.
Bridge mtu seems to only be able to be maxed at 1500. I tried the 2 e100 cards on the bridge set at 1504 with no effect.
Bridging does need a bigger MTU, and the bridge driver does not propogate the set mtu to the slave ethers. One workaround would be to set the mtu of the e100's prior to putting the ether's into the vlan.
I will fix this in 2.5.
Thanks for the quick response Stephen.
Does this mean an MTU of 1504 is big enough for the e100s? Ifconfig did not allow me to make them any bigger :(.
I believe this may be a problem with VLANs and the eepro100 driver.
If you use the e100 driver from Intel it should just work with VLANs.
The eepro100 needs some hacking...archives and/or FAQ has info here: www.candelatech.com/~greear/vlan.html
