stacking 460g2 with vim-2x

Dean_Ferraro — Sat, 22 Oct 2016 08:28:00 GMT

I am trying to stack two 460g2 via VIM-2x modules with exos 16.1.3, and have cabled them the VIM modules from S2 to S1 and S2 to S1 and they show link lights but do not form a stack. This works fine on the front panel ports but not the VIM. I noticed I had to run alternate as native mode is not supported on this module. Any thoughts on what I am missing? Thanks

We will use VIM-2x card for stacking when we have 1G switch for stacking. You can do show stacking-support to see which ports can be used for stacking.

Thanks. I will give native a shot on Monday, but am fairly confident I read these cards do not support native stacking. Also I can see the ports available for stacking as suggested, but couldn't find much documentation on the command syntax to change them. Any suggestions?

Hi Dean,

FYI, you may find useful configuration and troubleshooting guide here:

Just found this same link as well. I will be trying to set back to Native and advise. Thanks

Looks like I may have misread the initial question. I read it as VIM-2q, not VIM-2x.

The VIM-2x can be used for Alternate stacking with the 1G models of the X460-G2. The 10G X460-G2s use the front panel 10G ports for Alternate stacking. See the following table for which ports to use with which switches:

Ok tried Native mode to no avail. I do not seem to be able to stack via the VIM-2x module at all. The only successful stacking config that appears to be working, is with Alternate Stacking and the front panel ports 51 & 52. Can ports 53 and 54 be configured on the VIM-2x and be used for stacking? I am beginning to think not since the show stacking-support command only shows ports 51 & 52. Can stacking be performed with the VIM-2x module? If so how is this accomplished? Thanks

Thank you Brandon. Based on the difficulties I am experiencing and the document you have provided, I am surmising that stacking is not possible via the VIM-2x with these switches.

That's correct. The 10G X460-G2s can only be stacked via alternate stacking using the front ports (51 & 52).
