Dear Team,
I have a strange problem...... This is my problem i have a linux box running Xen kernel (2.2). and i have the a bonding interface called bond0.497(eth0 and eth1 and also des Vlan tagging).
the bond0.497 is part of the bridge "xenbrv497", the issue is as soon as i make the bond a part of the bridge my network traffic stops to work.
I did some prelimanary tests and found the following:
1) if i assighn an ip to the bond and do a ping to the gateway it works (provided it is not part of bridge xenbrv497)
2) if i add the bondig interface to the brodge xenbrv497 (brclt addif xenbrv497 bond0.497) the ping tests fails.
3) i did a tcpdump and found that arp requests are going out of the interface and we are getting response also. but soemhow
the arp entries are not gettign registered. i did some googling and found it may be because of filtering so i disabled it by
echo 0 > in /proc/sys/net/bridge/bridge-nf-*.
But even this did not help still the arp entries are not getting registered due to which my network traffic is gettign dropped.
This problem can be resolved by a reboot. but i would like to troubleshoot it.
Could you please let me know how i can get more debugging message from the bridge calls so i can figure out what exactly is happening.
