Re: How to check if WLC is configured for DHCP or not

Hi Mahesh,

Yes, this mean you have not configured your WLC to act as a DHCP server with pre-defined pools.

If clients getting IP address they should get it from an external dhcp server.

If you check the interface configuration you should see a DHCP server IP address configured. In CLI if you type "show interface detailed " that also provide the configured DHCP server information

Here is an example of such CLI output

(4402-3) >show interface detailed vlan130

Interface Name................................... vlan130

MAC Address...................................... 00:0b:85:43:d8:67

IP Address....................................... 192.168.130.33

IP Netmask....................................... 255.255.255.0

IP Gateway....................................... 192.168.130.1

External NAT IP State............................ Disabled

External NAT IP Address.......................... 0.0.0.0

VLAN............................................. 130      

Quarantine-vlan.................................. 0

Active Physical Port............................. LAG (29)

Primary Physical Port............................ LAG (29)

Backup Physical Port............................. Unconfigured

Primary DHCP Server.............................. 192.168.130.1

Secondary DHCP Server............................ Unconfigured

DHCP Option 82................................... Disabled

ACL.............................................. Unconfigured

AP Manager....................................... No

Guest Interface.................................. No

L2 Multicast..................................... Enabled

Hi Anas,

>show dhcp summary

No scopes defined

Does this mean that users are getting ip from the External dhcp device?
