Hi, This is part of my dmesg output which is generated whenever some network topology changes. It is very annoying. Any ways for me to inhibit those which are only informational but not warnings which I need to take care? I am running the all bridges on tap* interfaces emulated by OpenVPN. I am running stock 2.6.8 kernel from Debian sarge. Please CC me Thanks! ---8<---8<---8<---8<---8<---8<---8<---8<---8<--- br0: port 1(tap0) entering listening state br0: port 1(tap0) entering learning state br0: topology change detected, propagating br0: port 1(tap0) entering forwarding state br0: port 1(tap0) entering disabled state device tap1 entered promiscuous mode br0: port 2(tap1) entering listening state br0: port 1(tap0) entering listening state br0: port 2(tap1) entering learning state br0: port 1(tap0) entering learning state br0: topology change detected, propagating br0: port 2(tap1) entering forwarding state br0: topology change detected, propagating br0: port 1(tap0) entering forwarding state eth0: no IPv6 routers present tap0: no IPv6 routers present br0: no IPv6 routers present tap1: no IPv6 routers present br0: topology change detected, sending tcn bpdu br0: port 2(tap1) entering blocking state br0: neighbor 8000.00:ff:04:c8:95:4e lost on port 1(tap0) br0: port 2(tap1) entering listening state br0: port 2(tap1) entering learning state br0: topology change detected, sending tcn bpdu br0: port 2(tap1) entering forwarding state br0: neighbor 8000.00:ff:16:cb:25:97 lost on port 2(tap1) br0: topology change detected, propagating br0: received tcn bpdu on port 1(tap0) br0: topology change detected, propagating br0: topology change detected, sending tcn bpdu br0: port 2(tap1) entering blocking state br0: neighbor 8000.00:ff:05:d2:76:ca lost on port 1(tap0) br0: port 2(tap1) entering listening state br0: port 2(tap1) entering learning state br0: topology change detected, sending tcn bpdu br0: port 2(tap1) entering forwarding state br0: received tcn bpdu on port 1(tap0) br0: topology change detected, sending tcn bpdu br0: received tcn bpdu on port 1(tap0) br0: topology change detected, sending tcn bpdu br0: received tcn bpdu on port 1(tap0) br0: topology change detected, sending tcn bpdu br0: neighbor 8000.00:ff:16:cb:25:97 lost on port 2(tap1) br0: topology change detected, propagating br0: received tcn bpdu on port 1(tap0) br0: topology change detected, sending tcn bpdu br0: neighbor 8000.00:ff:16:cb:25:97 lost on port 2(tap1) br0: topology change detected, propagating br0: topology change detected, sending tcn bpdu br0: port 2(tap1) entering blocking state tap0: received packet with own address as source address tap0: received packet with own address as source address tap0: received packet with own address as source address tap0: received packet with own address as source address tap0: received packet with own address as source address br0: port 2(tap1) entering listening state br0: port 2(tap1) entering learning state br0: topology change detected, sending tcn bpdu br0: port 2(tap1) entering forwarding state br0: neighbor 8000.00:ff:16:cb:25:97 lost on port 2(tap1) br0: topology change detected, propagating br0: received tcn bpdu on port 1(tap0) br0: topology change detected, propagating tap0: received packet with own address as source address br0: topology change detected, sending tcn bpdu br0: port 2(tap1) entering blocking state br0: port 2(tap1) entering listening state br0: port 2(tap1) entering learning state br0: topology change detected, sending tcn bpdu br0: port 2(tap1) entering forwarding state br0: neighbor 8000.00:ff:16:cb:25:97 lost on port 2(tap1) br0: topology change detected, propagating br0: topology change detected, sending tcn bpdu br0: port 2(tap1) entering blocking state br0: port 2(tap1) entering listening state br0: port 2(tap1) entering learning state br0: topology change detected, sending tcn bpdu br0: port 2(tap1) entering blocking state br0: neighbor 8000.00:ff:05:d2:76:ca lost on port 1(tap0) br0: port 2(tap1) entering listening state br0: received tcn bpdu on port 1(tap0) br0: topology change detected, sending tcn bpdu br0: port 2(tap1) entering learning state br0: neighbor 8000.00:ff:16:cb:25:97 lost on port 2(tap1) br0: topology change detected, propagating br0: topology change detected, propagating br0: port 2(tap1) entering forwarding state br0: topology change detected, sending tcn bpdu br0: port 2(tap1) entering blocking state br0: port 2(tap1) entering listening state br0: port 2(tap1) entering learning state br0: topology change detected, sending tcn bpdu br0: port 2(tap1) entering forwarding state br0: topology change detected, sending tcn bpdu br0: port 2(tap1) entering blocking state br0: neighbor 8000.00:ff:05:d2:76:ca lost on port 1(tap0) br0: port 2(tap1) entering listening state br0: port 2(tap1) entering learning state br0: topology change detected, sending tcn bpdu br0: port 2(tap1) entering forwarding state br0: neighbor 8000.00:ff:16:cb:25:97 lost on port 2(tap1) br0: topology change detected, propagating ---8<---8<---8<---8<---8<---8<---8<---8<---8<--- -- Regards, Alan
