Nexus N7706 with F3-348XP-23 line card VDC port allocation.
While i have worked with Nexus for some time, i have never had to assign more than 12 ports to one VDC and some of the old cards did not have certain restrictions. I seemed to be getting conflicting information from different documents
On the F3-348XP-23 line card, installed on a N7706
1. Can i assign port p1 to 24 in one VDC and p25 to 40 in a different VDC regardless of the port allocations in the link below which has this diagram.
I know this is an old thread and old question, and you might have already found the answer, however, I would like to clarify this, as there might be people having similar queries.
First, all Nexus 7000/7700 have the interfaces bound together into something called port-groups. As you know, interfaces can be allocated from one VDC to another, but the only restriction regarding port allocation is that if you want to move a port, you need allocate the full port-group.
As a practical example, let's take N77-F348XP-23. This is how ports are allocated into the port-groups:
Table 14. Port Numbers for Port Groups on the Cisco Nexus 7000 Series 10-Gbps Ethernet Modules (N7K-F348XP-25) and the Cisco Nexus 7700 Series 10-Gbps Ethernet Modules (N77-F348XP-23)
This means that if you want to move port 41 to a VDC, you need to move all 8 ports into that VDC. There is no exception to this rule. In fact, while doing the "allocate" command, there will be a prompt notifying you that all 8 ports part of the port-group will be moved.
