NimbostratusHi, 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. Anybody know, Do we have any issue when we implement it, this is production network with all our of websites traffic go through this connection interface. Thanks
NacreousYou'll have a (off the top of my head) 2 minute outage as STP recalculates.
NacreousOr 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?
NimbostratusHi, 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 ?
NacreousYou 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.
