See the
Cisco NX-OS
FCoE Configuration Guide for Cisco Nexus 7000 and Cisco MDS 9500 for
information on allocating interfaces for storage VDCs and FCoE.
|
The only physical resources that you can allocate to a VDC are the physical interfaces. You can assign an interface to only
one VDC, except in the specific case of shared interfaces that carry both Fibre Channel and Ethernet traffic. You allocate
a shared interface to both an Ethernet VDC and to the storage VDC. When you move an interface from one VDC to another VDC,
the interface loses its configuration. The output of the show running-config vdc command has two entries for storage VDC. The first entry has details of all configurations except FCoE VLAN range and shared
interfaces. The second entry, which appears at the bottom, has details of FCoE VLAN range and shared interfaces. This entry
is placed at the bottom to avoid the configuration replay failure if the storage VDC is created before the ethernet VDC and
the interface is shared from the ethernet VDC. You can create the ethernet VDC in any order if this entry is placed at the
bottom.
When you first create
a VDC, you can specifically allocate interfaces to it. All interfaces initially
reside in the default VDC (VDC 1). After you allocate the interfaces to a VDC,
you can only view and configure them from that specific VDC. You can also
remove interfaces from a VDC by moving them back to the default VDC.
Caution
|
When you move an
interface, all configuration on the interface is lost and the interfaces are in
the down state.
|
Note
|
Beginning with Cisco
NX-OS Release 5.2(1) for Nexus 7000 Series devices, all members of a port group
are automatically allocated to the VDC when you allocate an interface.
|
You must be aware of
the hardware architecture of your platform when allocating interfaces to a VDC.
You can allocate the interfaces on your physical device in any combination.
Beginning with Cisco
NX-OS Release 6.1, the following M2 Series modules are supported on Cisco Nexus
7000 Series platforms:
-
24-port 10G
(N7K-M224XP-23L)
-
6-port 40G
(N7K-M206FQ-23L)
-
2-port 100G
(N7K-M202-CF-22L)
Note
|
There is no port
group restriction on M2 Series modules. Any port in M2 Series modules can be
placed in any VDC.

You must allocate the interfaces on
your physical device in the specified combination on the Cisco Nexus 7000
Series 32-port, 10-Gbps Ethernet module N7K-F132XP-15. This module has 16 port
groups that consist of 2 ports each. You must assign the specified port pairs
in the same VDC. The table below shows the port numbering for the port groups.

You must allocate the interfaces on your physical device in the
specified combination on the Cisco Nexus 7000 Series 48-port, 10-Gbps Ethernet
modules N7K-F248XP-25[E] and N7K-F248XT-25[E]. These modules have 12 port
groups that consist of 4 ports each. You must assign all four ports in a port
group to the same VDC. The table below shows the port numbering for the port
groups.
