Cat6800 to new c9800 WLC via PO71

[williamsonjason]

Hi all, Im having trouble getting my cores to route to my new WLC... 

I cannot ping the core from the WLC, and cannot ping the wlc from the core. 

Cores to WLC: 2 interfaces, members of PO71. VLAN allowed statement in use (allowed vlan 271)

WLC to Cores: 2 interfaces, members of PO3. VLAN allowed statement in use (allowed vlan 271 (tried ALL, as well)

"Show cdp nei" on the WLC shows me that the core interfaces are connected & cdp is working. 

WLC mgmt IP is 10.3.2.11 (cannot ping from core)
Core Int vlan 271 IP is 10.3.2.2 (pings from the core & my laptop)

network statement exists:
router ospf 103
router-id 10.x.x.x (removed for security)
network 10.3.2.0 0.0.0.31 area 0

coreswitch#show ip arp | inc 10.3.2.
Internet 10.3.2.2 - 0008.e3ff.fc28 ARPA Vlan271 (the int vlan 271 IP)
Internet 10.3.2.11 0 Incomplete ARPA (supposed to be my wlc - but why is it imcomplete?)

Can you share show etherchannel summary from both sides and share spanning tree on SW side.

Passive Interface?

[williamsonjason]

Leo, are you talking about an ospf.passive statement or something else?
