Bootstrap from DHCP with Cisco 2960-X, 3560-C/CX

Hi guys,

I've got Prime Infrastructure 3.0.2 installed and I'm trying to get Plug and Play (PnP) working with CNS on PI.

- The switches we tend to deploy are 2960X, 3560-C/CX and I have got our Windows DHCP server configured with Option 150 to point to PI.

However when plugging these 'out of the box' switches into our network, the switches don't get an IP via DHCP...

- I don't think they are shipped with IP address DHCP on the Vlan 1 interface.

How can I get this working without having to console into each switch??

I have tried bootstrapping from a USB drive but with no success because the switch still doesn't have an IP address on any SVI or interface.

Any help would be greatly appreciated.

Thanks,

Brad

I am having the same issue.

I am having the same issue. Were you able to find an answer?

I can't work out how to make the switch look for a DHCP address and can't find any documentation for this feature.

Hi Pedro,

Hi Pedro,

Sorry I'm still having the same issue. I can't work out how to get it to work.

I've logged a TAC case.

I've logged a TAC case.

I can't see any documentation explaining under what conditions the C2960X will try to find a DHCP server.

TAC came back and suggested

TAC came back and suggested doing a "write erase" and a reload.

I did this and connected int gi1/0/1 to a normal access port on one of our switches.

After the switch loaded it found the DHCP server and loaded the bootstrap config.

Hi Pedro,

Hi Pedro,

Thanks for the update! I managed to get my switch to actually boot to the AUTOINSTALL command too... but my switch actually trys to use OPTION 66 (BootServerHostName) instead... :(

I need option 66 in my DHCP scope for use with our Microsoft SCCM infrastructure but it appears as though the AUTOINSTALL uses Option 66 before it looks at Option 150!

I may need to start a TAC case for my scenario... 

Cheers,

Brad
