Few switches are distributing 169***** series ips instead of 172 series.

if this is only then i would go physically check what device is connected to this port - and fix the IP information (this may cause malfunction of Interface cards sometimes I have observed)

firest this 169.x.x.x IP is assign to PC that can not get it IP from DHCP.
there is issue in your DHCP server or DHCP local pool

We have reconfigured the DHCP configuration of the branch post DHCP configuration also not taking DHCP ip while we are assigning static ip pc is running smoothly.
02-16-2023 03:56 AM
Yes, workaround is manually config the IP
what is issue with DHCP ?
02-16-2023 04:20 AM
