Using DAC cable for keep-alive connection

[michakushner]

Hi,

I understand from posts that although it is possible to use Mgmt port for keep-alive between Nexus 3524P switches, although it is not recommended.

This means buying two (or four) copper SFP's for keep-alive connection.

Is it possible to use a DAC (Direct Attach Cable) cable between the switches for keep-alive?  

A DAC cable is much cheaper than two SFP's.

Thanks in advance

That is correct. DAC cable is much cheaper and DAC cables are usually compatible with Nexus.

I usually get them here:

They are reasonable and usually work with Cisco with no issues.

Hello michakushner,

No problem to use DAC with keep-alive, I used in a lot environments in two Nexus and work fine.

Caution only of matrix, cable X switch model.
