Configuration of Cisco WLC 2504 with Local LAN static IP and DHCP

[Ashish Kumar]

I want to configure Cisco WLC 2504 with Local LAN static IP and WLC 2504 with DHCP so that APs can be connect with controller.

Currently i am using WLC 2504 with DHCP so can anyone suggest how to do that..

HI Ashish,

Example:

Here WLC and AP are in same VLAN.

Here is teh attached config for WLC 2504.

Swicth port config where WLC connected:

interface GigabitEthernet 0/xx

description *** WLAN Controller ***

switchport trunk encapsulation dot1q

switchport trunk allowed vlan 80-81

switchport mode trunk

speed 100

duplex full

On core swicth DHCP pool is created to assign IP to AP:

ip dhcp excluded-address 10.xx.80.1 10.xx.80.100

ip dhcp excluded-address 10.xx.80.115 10.xx.80.254

!

ip dhcp pool WirelessLAN

   network 10.xx.80.0 255.255.255.0

   default-router 10.xx.80.254

   option 43 ip 10.xx.80.1

   lease 3

-----------------------------------------------------------------

Swicth port config where AP connected:

interface FastEthernet0/xx

description *** AP ***

switchport access vlan 80

switchport mode access

Hope it helps.

Hi Sandeep,

Thanks for sharing the configuration.

Actually i don't want to use a switch in this scenario for DHCP, I just want to configure a port of WLC 2504 controller with static LAN IP and another one for DHCP configuration so that i can connect that WLC 2504 controller with my local LAN and APs with that controller.

Thanks

HI Ashish,

Directly connected APs are not supported on the 2500 platform. Please see the 2500 deployment guide:

Check this Link:

http://www.cisco.com/en/US/products/ps11630/products_tech_note09186a0080b8450c.shtml

"The Power over Ethernet (PoE) ports on the Cisco 2500 Series Wireless Controller will not support directly attached APs."

Hi Sandeep

The info is correct, if we're using code below 7.3.101.0.

This issue is fixed via the below bug id.

CSCto01390 Unable to ping AP's directly connected to a 2500 controller

check the fix that is updated on 7.4, 7.5 RNE.

http://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn75.html

Note

Directly connected APs are supported only in Local mode.

http://www.cisco.com/en/US/prod/collateral/wireless/ps6302/ps8322/ps11630/data_sheet_c78-645111.html

For quick and easy deployment Access Points can be connected directly to 2504 Wireless LAN Controller via two PoE (Power over Ethernet) ports

Thanks

#on 2500, ofcourse you can configure static ip on management and dynamic interface.

#Wired device can't get ip from WLC's dhcp pool, only AP and wireless can get ip.
