I am trying to create a port channel between HP servers (4 nic) and two nexus 2k. The server side its a single team with 803.2ad fault taulerence and on the nexus side it have created two port channel (port channel 1 for nexus 2k1 and port channel 2 for nexus 2k2) and made them ACTIVE (channel group mode active)
But when i add a another server on different ports and port channel them the same way as the above server on nexus 2k1 and nexus 2k2, the first server stops pinging. so i have to sht down the first port channel and reopen them - then it works, however it says NO NETWORK ACCESS on the servers (running windows 2008). the only way is to reboot the server i cant be doing this on a production network.
any ideas why this would happen ?
Seen this behaviour on a 5k Nexus with HP servers.
They get too much probleme with servers that does not respect the RFCs with the new code.
Did you try to upgrade the drivers/teaming software and try again ?
Give us some logs on the Nexus/Server
yep tried upgrading the software but doesnt work.
i found that this is a bug on the nexus 7k where one port channel drops on adding another one.
Existing Portchannel (HIF) breaks when other PC(HIF) on same FEX flaps
Port-channel with more than 1 member in it going from FEX to the end hosts. Connectivity issue is seen on an existing port-channel when a new port-channel is brought up or an existing port-channel is flapped.
When a new port-channel is flapped or an existing one is flapped.
Needs NX-OS updating to 5.2 or later
