Hi @davariganesh1994 ,

 

I leave you a couple of links. The first is a guide to problems with dhcp and the second of a discussion about a bug reported:

I hope that they are useful for you

Re: Intermittent connectivity issues while connecting cameras on Cisco 2960 series switch

Hi,

May I ask a few questions:

if I shut and no shut switch port, it takes IP for 5-10 sec only,  after it shows APIPA  address,

1.  What is port configuration and any logs generated related to STP or POE?

2. What are the firmware version and POE budge? 

3. Have you tried with POE injector? is reported issue repeated with POE injector?
