I can’t figure out if I hate this platform, or if I hate this card. It has without doubt subtracted more from amount of years I got left in this life than the amount of cigarettes I’ve been smoking.
This command causes the card to crash:
# conf t
conf# interface gi1/0/1.111
conf(subif)# encapsulation dot1q 11 second-dot1q 11
Yes, that’s right. It will let you configure QinQ routing but it will crash.
What I uncovered today was that it uses the same mac address on all it’s interfaces including EoMPLS connections. This causes nasty mac-flap issues if you tunnel your vlans in a layer-2 network. Ouch!
So, if you plan on using this interface, change all mac addresses on each interface before you start…
Nice one, Cisco…
