Question

DHCP not issuing out IP addresses

Feb 24, 2015 4:19PM PST

My DHCP network is no longer issuing out IP addresses. Every new device must be manually configured to connect to the network. After executing
show ip dhcp binding, i noticed that all the ip addresses were assigned (with infinite leases). Executing show run gives:

Current Configuration: 1971 bytes
<span>!
<span>version 15.2
<span>service timestamps debug datetime msec
<span>service timestamps log datetime msecno
<span>service password-encryption
<span>!
<span>hostname myhost
<span>!
<span>boot-start-marker
<span>boot-end-marker
<span>!
<span>!
<span>!
<span>no aaa new-model
<span>!ip cef
<span>!
<span>!
<span>!
<span>ip dhcp excluded-address 192.168.1.2 192.168.1.60
<span>ip dhcp excluded-address 192.168.1.109 192.168.1.116
<span>

and executing show ip dhcp pool gives:


Utilization mark (high/low) : 100 / 0
Subnet size (first/next) : 0 / 0
Total addresses : 254
Leased addresses : 183
Pending event : none
1 subnet is currently in the pool :
Current index IP address range Leased addresses
0.0.0.0 192.168.1.1 - 192.168.1.254 183
<span>

<span id="INSERTION_MARKER">My questions are:
<span>

<span>1. Will removing the infinite leases on the already assigned IPs solve the issue?
<span>

<span>2. How do i increase my DHCP pool? Perhaps to give IPs in the form 192.168.0.x . As shown above the gateway is 192.168.1.1 with subnet 255.255.255.0
<span>

<span>The router in use is a cisco 1941 router. Don't have much experience with cisco CLI, i would appreciate the commands to execute (2) above.
<span>

<span>Thank you.

Odd to add all that. You left out what is running the DHCP service so no direct answer is possible.
