F5 10000 Series, LTM - External Interface not comunicating - up on switch, up on F5 interface

Last Modified: 2015-03-24
On, a secondary standby LTM I am trying to configure.. the external interface shows as up, the switch it is connected to shows as up/up... however the cisco switch doesn't show the mac of the F5 in it's table and the ARP shows up as unresolved, incomplete, or just not there at all.

I tried just about everything I can think of, switch out sfps, changed interfaces, hardcoded everything, set everything on the switch and the F5 interface to exaclty the settings as another 10000 series that is working just fine... no matter what I have done so far, I can't get that port to pass traffic. According to the stats the F5 has inbound but no outbound traffic. The switch shows in and out traffic but no mac for the switch interface...

route is same to the gateway address. to GW Address which was pushed from the primary.

The primary works fine, I can ping the self ip, floating ip, and vs ip. If I fail it over to the secondary, I can't ping the floating or the vs address either. same vlan and tagged with the correct switch vlan id.

Any Ideas? This has got me stumped!
