10Gig-E stacking links not shown

[thomasdav]

I have Virtual Connect Ethernet modules in Bays 1-4. I have a CX4 cable connecting Bay 1 port X1 to Bay 3 port X1 and another CX4 cable connecting Bay 2 port X1 to Bay 4 port X1 (just as shown in the user guide). But I do not see the stacking links in Virtual Connect manager. Anybody seen this issue?

Make sure the links you are using for stacking are not defined in any networks.

Make sure your firmware is at 1.16. There are some enhancements to the CX4 signaling in that version:

How long are your cables? Are they Infiniband cables (these might not work correctly)?

Stacking Link cables must be from .5 meter to 7 meter lengths and support IEEE CX4 spec for 10Gb Communication.

As a test to make sure stacking is working you might try some 1 Gb connections to see if stacking links are formed.

The issue was with the OA module. After failing over to the standby OA, all of the stacking links were visible.
