I have a machine running 2.6.18-rc3 with a bridge config that looks like
this:
cr1:~# brctl show
bridge name bridge id STP enabled interfaces
vlan100 36b0.0007e90f40c1 yes eth0.100
eth2.100
vlan101 5dc0.0007e90f40c1 yes eth0.101
eth2.101
vlan102 5dc0.00e08163c33f yes eth3
vlan200 5dc0.0007e90f40c1 yes eth0.200
eth2.200
vlan201 5dc0.0007e90f40c1 yes eth0.201
eth2.201
vlan300 5dc0.0007e90f40c1 yes eth0.300
eth2.300
vlan301 5dc0.0007e90f40c1 yes eth0.301
eth2.301
vlan302 5dc0.0007e90f40c1 yes eth0.302
eth2.302
vlan303 5dc0.0007e90f40c1 yes eth0.303
eth2.303
All bridges, except for vlan102, are running STP and appear to have
elected themselves the root bridge.
I see this on the console:
printk: 18 messages suppressed.
eth2.100: received packet with own address as source address
printk: 20 messages suppressed.
eth2.200: received packet with own address as source address
This repeats continuously, only indicating an issue on the two specific
ports mentioned above. This confuses me:
1) All VLANs (except for 102) are in an identical configuration
2) No other VLANs exhibit the same kernel message
3) I have another machine, running 2.6.18-rc2 with the same config and
no kernel message
Is this message specifically related to BPDU frames, or is it pertaining
to any Ethernet frame on the port?
Here is the STP config for one of the bridges. What's the next step to
troubleshoot this?
