NIC teaming on windows server

ALL

 

 

We ran into problem where servers behind f5 were doing nic teaming. So traffic was going out on both nics . This did not work well with f5 ltm version 9.4.8. Once we changed the nic teaming to one nic it worked.

 

 

does f5 support active/active nic teaming ? and if it does how do u implement it? we can't use fast4profile because we need cookie .

 

 

 

 

config
design

    Did you create a trunk on your F5 box? You can find this under the network section.

    SOL3009 has info on this. Basically, if you do want to use teamed NICs, you can't use the PVA as it won't be able to handle a change in MAC address mid-session.

    But as Chris said, using trunks is a more resilient option.

    yes I did use trunking. It seems like if the server is configured for nic teaming with load balancing method it won't work. You have to be in a fault tolerance mode meaning active/standby mode . active/active does not work with f5

    Hi Kirit,

     

     

    If you've tried 802.3ad trunking and are seeing issues, I suggest opening a case with F5 Support to get help troubleshooting the issue.

    Are you connecting the server direct into the F5? Or do you have a switch between them?
