I am stacking 2 x670V switches for our main core.  Since all ports are 10G sfp we are setting up the stack to use Ethernet ports as alternate stacking ports (Ports 47 and 48).  I setup it up like it said in the concepts guide and it runs nice so far (limited testing for now).  When I ran show ports command to see everything I saw this.  I reran the command with just the last 10 ports on each slot.

   Link State: A-Active, R-Ready, NP-Port not present, L-Loopback,
               D-ELSM enabled but not up
               d-Ethernet OAM enabled but not up

The last 4 ports on each slot show as NP (not present).  I understand that 47 and 48 would be NP since we are stacking with those two ports, but I don't know why 45 and 46 are, unless the switch has to cannibalize 2 extra ports to stack with Ethernet.

Hi ethernet,

Thanks for the reply.

Interesting. I would open a case with TAC just to ensure what you're running into is a normal behavior or not.
