Re: SNMP config problem on two of seven hosts

This looks like it's higher in the pipeline. tcpdump doesn't show any
traffic until after the timeout threshold has been exceeded.

Now I guess the question is this: why do those packets get queued for so
long? There *is* a txqueuelen: 1000 on the interface, but the same is
set on the 5 VMs that work.

It looks like this is off topic now, so I'll leave it at this.

Cheers,

C.J.
