Thank you so much Ryan!
I didn't know the keyword "allowed" actually tags the vlan on the switch. So, to make things work, I just tagged the vlan on the F5 and everything is good now :)
THANKS!!

Considering the fact that youbre tagging the bundle and youbre not setting a native VLAN, you will need to tag from the F5 side. Based on what youbve said, if you set native to vlan 322, you should be able to ping your host. Here is an example config thatbs using an LACP bundle with VPC upstream pair. Ibm not doing any fancy with bundle (queuing etc), but I doubt thatbs your issue.

# trunk vpc-trunk {
# lacp enable
# interfaces {
# 3.1
# 3.2
# }
# }
# stp instance 0 {
# trunks vpc-trunk {
# external path cost 2000
# internal path cost 2000
# }
# vlans {
# F5-ext-hb
# F5-int-hb
# vlan_cs
# vlan_gw

Thanks,

Thanks Kal, Ryan. I test the flow by pinging the self IP on the F5, which I'm not able to. When I take off LACP, I can ping the self IP. STP is not running on the F5 interfaces.
I am running a single vlan on this trunk. So on the F5 side, I have set the same vlan on the trunk but the trunk is "untagged". Does it have to be tagged even if there's a single vlan active on the trunk?
I am not able to get the bigip_base.conf right now but will do so tomorrow during business hours.

thanks for the help!!

I assume you've set your vlan's to the new trunk to send traffic through the bundle. Can you post your bigip_base.conf with relevant data?

I have this same config in multiple environments, one with an 8900 as well. I'll share that section when I'm near a computer again.
