    For the past 2 days, the guest network DHCP IP are not releasing back to the pool of addresses. I called TAC yesterday, I was told to run: clear ip dhcp binding. I had to run it again this morning and I am afraid I will need to do it again before I leave for tonight. The log file did not show anything out of the ordinary today or yesterday for TAC. We did an upgrade to the OS back in Oct but this just started yesterday and nothing has changed in the configuration since the upgrade. Any ideas?

    What is the lease time?   What does "show ip dhcp bindings" show as the lease times that you have trouble with?

    Did you check "show ip dhcp bindings" to see what leases existed and if they were past their time?
