EX4550 VC questions

Hi all,

I'm installing an 2x 32GE Virtual Chassis Module into my EX4550. This is what I see when the module is installed:

{master:0}
root> show virtual-chassis vc-port
fpc0:

PIC / Port
2/0         Configured         -1    Down         16000
2/1         Configured         -1    Down         16000
2/2         Configured         -1    Down         16000
2/3         Configured         -1    Down         16000

I'm very confused by this result - why is the Type listed as Configured, instead of Dedicated? And why are there 4 interfaces instead of 2? And why do the interfaces show up as 16Gbps instead of 32Gbps?

According to this documentation, I should see VCP-2/0 and VCP-2/1. Does anyone have some insight as to what's going on here?

I'm running 15.1R5.5
