Interface Allocation

When you create a VDC, you can allocate I/O interfaces to the VDC. Later, the deployment of your physical device might change and you can reallocate the interfaces as necessary.


Note Beginning with Cisco 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.


The following Cisco Nexus 7000 Series Ethernet modules have four port groups that consist of 2, 4, 8, or 12 interfaces each, depending on the module: N7K-M148GS-11L, N7K-M148GT-11, N7K-M148GS-11, N7K-M132XP-12, or N7K-M108X2-12L. You must assign all interfaces in the corresponding port group to the same VDC. See the example for module N7K-M132XP-12 in Figure 4-1.

Figure 4-1 Example Interface Allocation for Port Groups on a Cisco Nexus 7000 Series 10-Gbps Ethernet Module (N7K-M132XP-12)

Table 4-1 shows the port numbering for the port groups.

On the Cisco Nexus 7000 Series 32-port, 10-Gbps Ethernet module (N7K-F132XP-15), you must allocate the interfaces on your physical device in the specified combination. This module has 16 port groups that consist of 2 ports each. You must assign the specified port pairs in the same VDC (see Figure 4-2).


Note You can configure the limit-resource line-card type command only from the VDC configuration mode and not from a VDC resource template.

Note When you add or delete interfaces, the Cisco NX-OS software removes the configuration and disables the interfaces.


VDC Resource Limits

You can change the resource limits for your VDC individually as your needs change. You can change the following limits for the following resources:

IPv4 multicast route memory

IPv6 multicast route memory

IPv4 unicast route memory

IPv6 unicast route memory

Port channels

Switched Port Analyzer (SPAN) monitor sessions

VLANs

Virtual routing and forwarding instances (VRFs)

HA Policies

The HA policy determines the action that the physical device takes when the VDC encounters an unrecoverable field. You can change the HA policy for the VDC that was specified when you created the VDC.


Note You cannot change the HA policies for the default VDC.


Saving VDC Configurations

A user with the vdc-admin or network-admin role can save the running configuration of all VDCs on the physical device to the startup configuration or can save the running configuration of a single VDC to a file in the bootflash directory.

MAC Addresses

The default VDC has a management MAC address. Beginning with Cisco Release 5.2(1) for the Nexus 7000 Series devices, subsequent nondefault VDCs that you create are assigned MAC addresses automatically as part of the bootup process.

You will see a syslog message if there are not sufficient MAC addresses to supply all the VDCs on the device.

Shared Interfaces

In the current Cisco NX-OS VDC model, you can move interfaces to a given VDC. The interface that is moved is dedicated to that VDC and carries all control and data traffic. VDCs are not aware of the interfaces present in the other VDCs, which gives complete administrative fault-isolation to the user.

With FCoE technology, both Ethernet and FCoE traffic are carried on the same physical Ethernet interface. In the FCoE VDC, the physical layer protocols (except for CDP, LACP and UDLD, which are LAN protocols) are not enabled. If an FCoE-capable interface is moved to the FCoE VDC, carrying pure Ethernet traffic on that interface is not possible because the LAN protocols are not enabled. In order to carry both LAN and SAN traffic, a shared interface between the LAN and SAN VDCs is required.

M1/F1 Separation

The module-type (line card) based VDCs are supported in Cisco Nexus 7000 Series devices. Beginning with Cisco NX-OS Release 5.2(1), all modules are categorized into three types — M1, F1, and M1XL. By default, all three line card types are allowed in a VDC.

You can restrict the allocated ports based on the module-type configuration. When changing the module type for a VDC, the unsupported ports are moved to the unallocated pool. You cannot move a port to a VDC if the port type is not supported for that VDC.

Cisco DCNM supports the configuration of M1/F1 line cards on the VDC. When changing the allowed types on a VDC, Cisco DCNM removes the ports that are no longer supported and moves them to an unallocated pool.

Cisco DCNM enables users to manage unallocated ports and bind the unallocated ports to any other VDCs that support this port type. When a user tries to move a port to a new VDC, Cisco DCNM checks whether ports of that type are allowed inside the VDC.

FCoE VDC Enhancements

You can assign an interface to be a shared interface only on the F Series module and not on the M Series module. For more information about FCoE VDCs, see the Cisco Nexus 7000 Series NX-OS Virtual Device Context Configuration Guide, Release 5.x.

Beginning with Cisco NX-OS Release 5.2 (1), the following components have been added to the Virtual Device screen to support shared interfaces:

Summary Table

VDC Setup Wizard

Details Pane

Interface Association Pane

Log in to the default VDC with a username that has the network-admin user role.

DETAILED STEPS


Step 1 From the Feature Selector pane, choose Virtual Devices.

Step 2 From the Summary pane, double-click the device to display the list of VDCs.

In the Virtual Devices screen, the Summary Table component is enhanced to support shared interfaces.

The Summary Table contains a new column Type to display the VDC type. This column is not editable.

Step 3 The following VDC types are displayed:

Ethernet

Storage

The default VDC type is Ethernet.


Administrator VDC Support

Administrator VDC is the VDC which enables you to perform switch wide administrative functions. There are no ports, port operations, or protocols associated with the administrator VDC. Unlike the default VDC, the only function of administrator VDC is to enable administrative operations on the switch and the customized VDCs. Therefore in the DCNM all the screen operations, port, and port related oprations will be disabled for Administrator VDC.


Note The administrator VDC feature is applicable only to the Cisco Nexus 7000 series switches with supervisor-2 line cards.


You can migrate from default VDC to administrator VDC using CLI commands.

Use the system admin-vdc command to migrate the default VDC to administrator VDC and to move all the ports to unallocated pool and to remove any other additional configuration.

You can use the system admin-vdc migrate migrated vdc command to migrate the default VDC to administrator VDC and move all the ports and port related configurations to the newly created migrated VDC.

DCNM will trigger a rediscovery immediateky after a default VDC is migrated to an administrator VDC, and all the administrator VDCs will be displayed in the topology with the `A' icon to identify them.

If no migration is performed then the default VDC is automatically turned into administraotr VDC and any additional confifuration is removed.


Note Administrtor VDC and Default VDC cannot exist together in a switch.


You can click on the Copy Run to Start and Copy Run to Start for All VDCs buttons to perform the respective actions.
