[Linux-cluster] cman and bond isssue

[Steven Dake]

One possible problem is that your switch doesn't properly support
multicast or jumbo frames.  I suggest ensuring your MTU on all machines
is 1500 to test the jumbo frames possibility.

I have seen many switches advertised as jumbo frames which fail to
operate properly in multicast or heavy broadcast environments.
