Nexus 7004 - Interfaces didn't show up for Newly installed I/O module

[Mohamed Ali Askar Ali]

I have installed (offline) the new I/O module N7K-F312FQ-25 in the 4th slot of Nexus 7004 device. The 3rd slot is already running with I/O module N7K-M224XP-23L.

When I boot the device, the new module listed with status OK in the show module output. But, the interfaces of the module are not showing up in the interfaces list.  

Please guide do we need to configure any command on Nexus 7004 for the module to show up its interfaces.

Your help and support is highly appreciated.

is this VDC, have you allocated the resources ? can you show the module output ?

In nexus 7000 the interfaces of a new module needs to be allocated first to a specific VDC and only after that you will be able to see them.

switch# conf t
switch(config)# vdc <name>
switch(config-vdc)#  allocate interface ethernet <slot>/<port>-<last-port>  

This action needs to be done from default VDC or, if you have one, from admin VDC.

Do a "show run" and search for the VDC part to see how the existing interfaces are allocated.

Stay safe,

I tried to add interface in the current VDC and received the below error

ERROR: 1 or more interfaces are from a module of type not supported by this vdc

New Module installed is N7K-F312FQ-25 and

in the VDC configuration, limit resource command has supported module type as "limit-resource module-type m1 f1 m1xl m2xl".

Should I add any module-type in the limit resource command for the module "N7K-F312FQ-25".

Kindly help.

You need to change your VDC type from supporting F3 as well.

switch(config)# vdc vdc-name 
switch(config-vdc)# limit-resource module-type m2xl f3

For more details about how to manage your VDC, I would recommend you read the following documentation:

https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus7000/sw/vdc/config/cisco_nexus7000_vdc_config_guide_8x/managing-vdc.html

Note: pay attention to table 23 in case in the future you might plan on doing other mixes between different LC models.

Stay safe,

Sergiu

Hi Sergiu,

Thanks for your support. As you instructed, I changed the module type in the VDC and didn't encounter any issues. Following that, I allocated the new module interfaces in the current VDC. Everything is working fine.

As the devices are in production environment, it took time to make changes.
