169.x.x.x address from switch
I have a switch that is handing out 169.x.x.x. addresses. When I console into the switch, the config looks correct and I am able to ping out from the switch. How do I resolve this?
The simple answer would be to disable DHCP on the switch. How do you know the switch is passing out IP addresses? That is a little odd for a switch......

I know that devices get there IPs from the DHCP server, however, when I plug a device directly into a port on the switch, I get:
169.254.22.208
Is the switch no communicating with the DHCP server?
Here is the config:

I don't see DHCP config on the switch.
169.254.x.x is given out by MS Windows when a client can't communicate with DHCP server for w/e reason.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Do you have any idea where or what your DHCP server is? As a rule it should be the server if you have a server. Your switch has nothing to do with it. The computer gets (should get) its IP address from the DHCP Server.
Do you have a server? If so what OS?
Do you have a server? If so what OS?
The DHCP server needs to be in the same VLAN, or the switch configured with an IP Helper to forward DHCP requests to and from other VLANs.

Issue was with misconfigured vlans on the core switch.
So https:#a41634243 is correct, no?
ASKER
After further troubleshooting, that is what worked.
Hi Gubbio,
Qlemo was correct in pointing that this was an issue with the DHCP configuration.
We would be glad to know how you fixed the issue.

We are segmenting our network by network closet and a vlan was configured incorrectly on the core switch (wrong closet).
Post config?
