Cisco 3260 - Ran out of address?

Hi,

I have an Internet router (c3260) and for some reason users are not able to get any ip's off of it anymore. I suspect that I need to increase the dhcp pool, but thought that I run this by you guys and see what comes up....

First thing, why do you want the length of the lease to be 365 days??? Second, you can do a "sh ip dchp bind" to see what ip are being used.

Why 365? Because this router is strictly for Internet access (bypassing proxies), for better reasons, some users "work" aren't too kin on proxies. show ip dhcp binding - I did see a lot of binding going on there. I would assume that is the reason why you won't recommend keeping the lease for that long. So, I cleared the binding on the dhcp: clear ip dhcp binding *.

And that seems to fix it. Although, I highly doubt that this problem will go away forever. Thus, back to my initial question..........Does increasing the pool help in this situation?

How many users are you supporting?

BTW, instead of leasing for 365 days, why not just assign static ip's?

Okay. I did some requirements gathering and it turns out that I DID NOT need 365 days lease. So, reducing that to about every 30 days work out just fine.

I guess I was over analyzing/troubleshooting this simple issue.

:) Thanks guys!
