Thanks for the help on this...The response was not really what i was looking for, however I was able work around the issue (i believe, fingers crossed) by adding the aging time to the mac address table. mac address-table aging-time 1800
I have a N3248PXE-ON and i am trying to configure IP Device Tracking.  I have it set up and working, however I am getting IP addresses that will not fall off of the table when they go inactive. I know i can clear the table manually, but how or what is the command to have this happen automatically?  I currently have the following: ip device tracking ip device tracking probe interval 300 ip device tracking probe delay 10 then on the interfaces i have: ip device tracking maximum 2  (data line and voice line)   however, when a data line has a lease expire the old IP is being held in the table and the logs fill up saying --- IPV4DT[IPv4_Device_Tra]: ipv4dt_main.c(1756) 2946624 %% WARN IPv4DT Entry to on interface Te1/0/23 in VLAN xx is not added into IPv4DT Tables as interface limit is reached.  Thanks
