[plug] Ethernet Bonding

[Adrian Woodley]

Only if you're doing link aggregation (which I'm not), not 
active-standby (which I am).

With active-standby, the switch(es) should only see traffic from one 
interface (and therefore one mac-address). If the primary link fails, 
traffic will start emanating from the standby interface. Regardless of 
whether the mac-address is the same (no arp needed, but switch(es) have 
to re-learn mac/switchport relationship) or different (switch should 
already know mac-address of standby, but hosts will need to re-arp for 
mac to IP relationship) there is no special config needed on the switch(es).

The problem I'm looking to avoid the problems caused by traffic leaving 
a standby interface with a source mac-address of the bond interface. 
This will cause the switch to (incorrectly) associate that mac-address 
with the standby interface / switchport.
