DHCP not releasing IP Address + Cisco IOS

[vinu4u4ever]

Hello, there.

I created a DHCP pool in our Cisco router 887 but unfortunately it is not releasing the IPs.

I'm new to Cisco so please ignore if it is a silly query.

Attached is the configuration taken from the Router.

Hi

Can you try executing these command lines:

(changing the network parameters)

Router(config)#ip dhcp excluded-address 192.168.3.1 192.168.3.99
Router(config)#service dhcp
Router(config)#ip dhcp pool DHCP-POOL
Router(dhcp-config)#network 192.168.3.0 255.255.255.0
Router(dhcp-config)#default-router 192.168.3.1
Router(dhcp-config)#dns-server 192.168.3.1
Router(dhcp-config)#domain-name home.local
Router(dhcp-config)#import all
Router(dhcp-config)#exit
Router(config)#end

Hello vinu4u4ever,

First things first, where did you get the name from.. Nice name vinu 4u 4ever better than watching the Kapil Sharma show.

Coming to the point.

1) Are all the host to connected to Vlan1? 

2) I'd also like to know what physical port on your router is allowing Vlan1.. Check your config. (issue may be here :p).

3) If you manually config the Ip address on the host are they able to ping 192.168.1.1?

4) Connect a computer directly to FastE x (allow vlan1 on that switch port) and see whether that computer gets an IP address.

Let us know if these steps help you resolve the issue.

If you find a post helpful. Kindly mark it helpful.

(Thanks to your post, I picked up a topic I always ignored and never learnt. After reading your post I picked up DHCP and now I know/learnt how to configure DHCP on a Cisco IOS router)

Regards,
Moses.
