New Interface on Cisco WLC 5508 will not respond

[johnsechrist]

Hello,

I am trying to configure an additional virtual interface on port 4 on a separate network segment on a Cisco WLC 5580 and it will not connect to the network, will not respond to ping, and can’t ping other devices on it’s network segment.  The new interface will not respond when pinged from the router that it is plugged into.

The wlc indicates that the port is up.

The router is working as expected and has been tested.

Even when I plug a PC into the new interface on port 4 the interface will not respond (the PC has the correct static ip config).

The mgt interface on port 1, Aps, and all connectivity from the mgt interface on port 1 is working properly.

Why will the new interface not respond and what can I do to get this configuration to work?

I have spent many hours reading and testing with no positive results.

Diagram attached:

Thank you.

Would you be able to test  by tag it to vlan 0 instead of 999 ?

I was at 0...same result. I changed it while experimenting.

I noticed your diagram shows F0/0 interface got mask /16 whereas on WLC /24. Can you confirm you configured correct mask on both sides

configure the router side as below and try pining.

R1(config)# interface f0/0
R1(config-if)# no ip address
R1(config-if)# interface f0/0.1
R1(config-subif)# description VLAN999
R1(config-subif)# encapsulation dot1q 999
R1(config-subif)# ip address 192.164.111.1 255.255.0.0
