ACI x Linux

[Raphael.Roumillac]

Hello Everyone
I am facing some issue regarding Linux connectivity on my fabric. The servers lose connectivity, I can't ping them, access via telnet or SSH. Although this scenario arp table remains fullfilled with all information. I faced this same issue with VMs, but it was solved disabling Directpath I/O option, but at this time I am facing the very same issue on Linux physical server. Anyone can help me?

Hi Raphael.Roumillac,

ACI handles ARP packets differently depending on your configuration.

You have told us nothing about your ACI configuration, or the configuration of the Linux hosts either.

I'd suggest that if you expect help from a forum, you put all the releveant information in your requst.

Are the Linux hosts on the same subnet?

Are the Linux hosts in the same bridge domain?

Are the Linux hosts in the same EPG?

Do the Linux hosts use ACI as their default gateway?

Do you have ARP flooding enabled on the BD(s)?

Do you have IP addresses assigned to the BD(s)? 

With so little information, so little help can be given.

BUT... as a starting point, try turning on ARP flooding on the relevant BDs if it is not already turned on.

Whatever the case, please get back to us so your information may help others in the same predicament.

I hope this helps

Hello RedNectar 

Question was solved... Linux administrator just configure a BOND with no LACP activated.

Solved configuring leaves interfaces as access.

Thanks a lot for your attention.
