How to tell the speed of the stack connections for summit switches?


Userlevel 2
If I only have ssh access to a remote summit switch (ie not onsite access to be able to visually see the hardware), how can I tell the speed of the stacking?

It's stack of (3) devices:
(2) 770s and (1) 670V

Can I tell via a command if it's using v.80, v160 or v320 I think are the options?

Thanks in advance

show stacking stack-ports
20G is V80
40G is v160
80G is v320

show stacking-support might also help you.

Hello Sarah

You can use the show stacking ports command. Below is an example from the concepts guide

Slot-1 StackA.13 # show stacking stack-ports
Stack Topology is a Ring
Slot Port Select Node MAC Address Port State Flags Speed

Also you can get some indication from the LEDs see page 152 of the 21.1 concepts guide. Sorry it would copy over very well.

Let me know if that helps to answer your question.

Thanks much, yes indeed

Just an additional information:

"The port speed is the unidirectional speed of the port.

Some VIM names include speed ratings which are 4 times the unidirectional stacking port speed. For example, the actual stacking port speed for VIM1-SummitStack512 is 128 Gbps. The 512 Gbps rating for the VIM is the unidirectional rate X 2 (bidirectional) X 2 (ports)."
