How to configure interface Nexus 7000?

[Nathaniel Horsch]

Hi,

I am just trying to configure the ethernet interfaces on my Nexus 7010 48 port module. When I do a "show interface" I only see the management interface on the management module and not the 48 port module. When I run a "show hardware" I am able to see that the module is plugged in to slot 1 and the status is "ok." I thought the interfaces would just show up once I connected the module. Is this not correct? And then I could access the ports with "interface ethernet 1/x" for the ports on module 1.

Thanks

Looked in there already. Seemed like the command should just be "interface ethernet 1/1" to configure port 1 on the module in slot 1. However I get an invalid range error and when I run "show interface" I only see the management blade interfaces rather than the 48 ethernet interfaces on the module.

Any ideas?

Hi Nathaniel,

Are you using non default VDC or RBAC on this switch. Can you attach show command output / show runn to check further.

Subhash, I believe I am using the default vdc on the switch.

show run shows:

It's as if the interfaces are not there. But with show hardware, I can see that the module is seen.

Take a read of the post Nexus 7009 does not show the N7K-F248XP-25 modules ethernet ports n sh run.

The solution there appears to be the use of the system module-type command.

Regards

[Nathaniel Horsch]

Thanks Steve. That seems to be very close to what I am looking for. We are running 6.1(2) right now but I see that it does not support the "system module-type" command. THat is only in 6.1(3). We are not able to get the upgrade yet due to SmartNet problems. Don't think there is a work around command on 6.1(2) that does the same thing...

[Steve Fuller]

Do you have any other I/O modules in the same chassis, either the M1, M2 or F1 series I/O modules? Currently the F2 and F2E modules needs to be in their own VDC.

As per the section Integrating F2 Series Modules Into a Cisco Nexus 7000 Series System in the NX-OS 6.1 release notes:

• An F2 Series module requires its own F2 Series module VDC. This VDC is restricted to the F2 Series module; M1 and F1 ports cannot be in the F2 Series module VDC. The default VDC can also be configured as an F2 Series module VDC.

Check output of 'show vdc membership' command. These interfaces will all appear
in VDC 0, which is reserved for unallocated interfaces:


vdc_id: 0 vdc_name: Unallocated interfaces:

Ethernet15/1          Ethernet15/2          Ethernet15/3
Ethernet15/4          Ethernet15/5          Ethernet15/6
Ethernet15/7          Ethernet15/8          Ethernet15/9


This needs to be allocated to your current VDC id 1. Refer below link for more information.

Allocating interfaces to a VDC:
http://www.cisco.com/en/US/docs/switches/datacenter/sw/nx-os/virtual_device_context/configuration/guide/vdc_mgmt.html#wp1186878
 If still it doesn't work, then you will need to create a separate VDC, configure that VDC to support the F2 module, and then allocate the appropriate interfaces to that new VDC.

Thank you very much guys. I was not able to add the ethernet ports to vdc1 since the admin vdc was not specified to handle f2 (and could not be set to handle it with limit-resources). Instead, I created another vdc and was able to allocate the interfaces and configure them.

Many thanks to both of you for your help!
