Description
RHEL Program Management

A patch addressing this issue has been included in kernel-2.6.9-89.32.1. As steps in https://bugzilla.redhat.com/show_bug.cgi?id=637764#c20, I cannot reproduce and verify this bug for RHEL4.8.z. With Flavio's help, I manage to do this in a new method. The host is dell-pe2850-04.rhts.eng.bos.redhat.com. First make sure eth0 and eth1 both have cables connected. 1. Configure following nics: # cat /etc/sysconfig/network-scripts/ifcfg-bond0 DEVICE=bond0 ONBOOT=yes BOOTPROTO=dhcp # cat /etc/sysconfig/network-scripts/ifcfg-bond0.10 DEVICE=bond0.10 ONBOOT=yes REORDER_HDR=no VLAN=yes BOOTPROTO=static IPADDR=192.168.55.63 NETMASK=255.255.255.0 # cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 ONBOOT=yes MASTER=bond0 SLAVE=yes HOTPLUG=no # cat /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 ONBOOT=yes MASTER=bond0 SLAVE=yes HOTPLUG=no 2. Then over console, # service network restart 3. In another ssh1, # tcpdump igmp -i eth0 4. In another ssh2, # tcpdump igmp -i eth1 5. Then over console, # ./multicasting-client.py Then currently active slave nic(eth0 in my case) from tcpdump should see something like 11:50:08.361289 IP 192.168.55.63 > IGMP.MCAST.NET: igmp v3 report, 1 group record(s) 6. In another ssh3, # ifenslave -c bond0 eth1 Then another nic(eth1 in my case) from tcpdump should very soon see something like 11:52:24.313758 IP 192.168.55.63 > IGMP.MCAST.NET: igmp v3 report, 1 group record(s) This igmp v3 report should be the same with the one in step 5. And this denotes the bug is fixed. Created attachment 463779 [details]
