I have dhcp set up on a switch (long story as to why).
Anyways all was well until i realised that i was having issues with machines getting ips. I look at the bindings and i see that i have ony 18. can anybody help me figure out why dhcp is crapping out?
ip dhcp pool Data
network 10.0.0.0 255.255.255.0
dns-server 10.0.0.38 10.0.0.9
no ip domain-lookup
ip dhcp excluded-address 10.0.0.1 10.0.0.124
ip dhcp excluded-address 10.0.0.226 10.0.0.254
Putney-5215Ave-3750-Sw-01#sh ip dhcp pool Data
Pool Data :
Utilization mark (high/low) : 100 / 0
Subnet size (first/next) : 0 / 0
Total addresses : 254
Leased addresses : 18
Excluded addresses : 236
Pending event : none
1 subnet is currently in the pool :
Current index IP address range Leased/Excluded/Total
0.0.0.0 10.0.0.1 - 10.0.0.254 18 / 236 / 254
why is it that 236 ips are excluded? am i missing something?
Given what you have posted it is difficult to know why the excluded addresses are 236. Is it possible that there are additional addresses excluded in a line that you did not show in your post? Is it possible that the configuration had excluded some other addresses and then was changed to reduce the number of excluded addresses but that this change has not fully gotten into DHCP yet? If you save the config and reboot the router do you still get 236 addresses excluded?
Just to confirm - you have reloaded the switch and the symptoms continue as they were. Is this a new implementation or has it been running for a while? Did it ever work correctly or has it had this problem since you configured DHCP? You have given us the parts of the config that you believe are important. I wonder if there is something else in the config that is causing this. Would you post the complete config masking sensitive information such as passwords?
Can you provide output from sh ip dhcp server statistics and sh ip dhcp conflict.
