Hi team,


we are facing problem on Cisco IOS Software, C2970 Software (C2970-LANBASE-M) switches connected hosts.

some of hosts are not getting ip address from DHCP server (Window based Server)

But on Switches showing desktop mac address in MAC database. Firewall Not coming in picture.


After release/renew ip getting on desktops.


Not found problem area.. in DHCP ? or in Switches ? or in Desktop side?



If anyone has any solution please update on priority.



Thank You

Hi Milind,

You could use Wireshark to do packet captures on both the client and the server so you can look at the DHCP transactions. That might give you some hints about where the problem is coming from.
