Ah okay - we've been installing both the MPLS and 10Gbps 
license at the same time, and running a reload. We haven't 
yet installed the licenses separately, so didn't test a more 
efficient way to bring 10Gbps ports into action. Thanks for 
that, Waris.

That's right.

Our initial tests were all based on 1Gbps uplinks using the 
10Gbps ports. That works fine.

We've just had a couple of units that seem to have bad 
uplink ports that read very low Tx output (-40dBm), to the 
extent of complete inability to function. Those have been 
RMA'd. Bad batch?

Apart from that, they work, along with OEM optics.

Waris, we prefer the EVC Xconnect feature, to limit 
configuration redundancy. It brings other problems 
(initially, anyway), but seems simpler. We're currently 
testing this as 15.1(2)EY has just come out, and we're 
forwarding production traffic on 12.2(52)EY2, which doesn't 
have this feature.

Any issues to look out for with EVC Xconnect in the early 
days of the code?

Cheers,

Mark.
