vlan tagging with bonding not reaching gateway

Stew McLeod — Fri, 28 Jan 2011 15:04:07 GMT

I have a DL380 G5 running RHEL5.3. I have two NICs that are bonded and want to use vlan tagging. i have my network-scripts set up for bond0. for both vlans and I can ping the devices but it fails when I try to ping the gateway. I can only access this via the ILO so cutting and pasting output is not possible(unless you can tell me how to do so). i can retype info if needed. thanks.

I don't know why both eth0 and eth1 have the same mac address. I tried hardcoding it in the network-scripts/ifcfg-ethX but it won't take.

output from netstat -rn:

Unfortunately I can't access any switch settings. Out network dept handles that and I was assured that they have it set up correctly.

Is there anything that stands out as being wrong? or does it look right and does in fact need to be checked on the switch side?

thanks.
