pc unable to get DHCP suddenly

[Mark Malone]

Whats happening with dhcp requests and offers are they reaching the users ? debug dhcp detail or wireshark the user pc to see if there receiving sending requests or who might be at fault switch or pcs , or else if it sounds like software just upgrade to another image to mitigate the bug

Hello,

is the (master) switch the DHCP server ? Can you post the configuration of the master and one of the stack member switches ?

the master sw is not the dhcp server. these stack switch connected to the core switch ( have ip address helper to the dhcp server)

1) Exhusted the dhcp scope?

I can't confirm, have to check with the server team
2) Duplicate ip address with dhcp server?

can't confirm
3) error disbale port state enabled

have to check, but I don't think so

4) rouge dhcp

not that I know
