Hi all
I’ve not found much information on this, so I’m hoping someone has come across this before. I have a number of Mellanox X3 dual port 10gbe adapters and I’m connecting them to a pair of Cisco 3548’s configured with vPC and teaming set to Dynamic 802.3ad (two ports, one to each 3548). Initially, all seems fine - the ports come up and vPC consistency is successful, but if I disconnect a port, I lose all connectivity. Further, if I change to Static mode teaming with the ports up and active (channel-group 1 mode active), I get a BSOD.
Mellanox team1 has no default gateway
Mellanox team2 has a default gateway
With everything up, I can ping a device on team1’s subnet
After eth1/1 shutdown, I see:
one port channel go down
pings continue for a few seconds
pings stop, I get a response from the default gateway saying no route to host
If I try to ping the IP of team1, I get the same (no route to host from default gateway)
On windows I see one of the team interfaces down, but the team is still up
On the second Nexus 3548, I can see the port is up and consistent
My questions:
-
if Windows says the team is up, if there is an issue with the switch config I would expect to see pings time out, not no route to host. Does this point to a driver/config issue in Windows?
-
are there any recommendations for vCP config and mellanox cards?
-
assuming LACP is preffered, what teaming mode should I use to enable LACP and not lose connectivity if one link goes down?
I’ve spent the better part of a day fighting with this, so any and all advice would be gratefully received!
Will
