convert single interface to the trunk with 2 interfaces.

Hi, currently, we have one F5 BIGIP (10.2.4) single interface connect to internet through FW . We want to add one more other interface and aggregate them (LACP) with 2 interfaces in the trunk to FW. ...

You'll have a (off the top of my head) 2 minute outage as STP recalculates.

    Or maybe not if the connection is direct between F5/firewall and not via intermediate switch. But I'd allow for a small traffic interruption.

     

    Do you have a standby device you can do this on first and then fail over to?

    Hi, Thanks for your reply, I will implement on standby F5 first but I did research online, some people also warning i may get some errors and we have to remove all vips, selfip related to that interface to clear errors. is it possible the error occur ?

    You should be able to remove the VLAN from the interface, alter the interface and then replace the VLAN (without having to remove virtual servers). I'm not 100% sure on this, hopefully someone else can comment here.

     

    You should be able to test this on an LTM-VE BTW.
