Devices takes too long to get IP address from Switch

[ODAT1]

I have Cisco Catalyst C9500-16X switch running ios version 16.12.4. as my core switch. I have configure dhcp on the switch for one of my vlans. initially, all devices were getting IP address from my dhcp server which sits in a different LAN but it was taking them too long for the devices to get an IP address. Now I have dhcp configure on the switch for one of my vlans and devices connecting to this vlan are still taking too long to get IP address. Can I get help resolving this issue?

Hello,

try and disable/enable the 'service dhcp':

9500(config)#no service dhcp

9500(config)#service dhcp

Hello you'll, thank you for all the great support provided. I was finally able to identify the issue and resolve it. After a debug, I found out the when I ping a host IP address, the reply will redirect to another hop. I remove ip redirect on the svi and the issue was fixed.

Command used 

no ip redirect

Thank you all.
