You need to raise your MTU above that on the other side and do a ping size sweep. Unlike at Layer-3 when you can use set a DF bit and get back an ICMP error, at Layer-2 when you exceed the far side's MTU, the packets are silently dropped.
In the past, I've found a binary search on ping size to be very efficient. YMMV, of course. -- Mike Andrews, W5EGO mikea@mikea.ath.cx Tired old sysadmin
