Wireless Access

Hello air heads

I'm evaluating the 9240 model controller for future use in our environment.  Unboxed a brand new one today and I am having a hard time getting the management interface to obtain a DHCP address.  Is there some trick to get it to work?  Currently we're using firmware version 8.10.0.15_91324.  In this version I believe the command to allow DHCP on the interface is simply "dhcp".  But it doesn't appear to be effective on this controller.  I tried in both mynode mode and in mm mode.  It never gets a DHCP address there are plenty of available IP's and other DHCP clients are working just fine.  Screen shot attached.

Should work if you are on 8.9 or up, which you are. Management port is sometimes a bit hard to troubleshoot as it's a special interface; and personally I try to avoid using it, but that's me. As there are no other responses, I would recommend to open a TAC case...

Herman,

Thank you for your reply.  My colleague suggested that only a static IP assignment is allowed on the mgmt interface.  But I don't see any documentation that says DHCP is not allowed.  So I figured I could try to make it work.

Can you say more about why you prefer to avoid using mgmt interface?

I try to avoid out-of-band management as in general it tends to create a backdoor into your network. If someone gains access to one device that's connected to the out-of-band management network, they can potentially use that to jump to other devices on that management network. So the management network would need to be segmented in the same way your production network is, and you need to secure access to and from that network. By using in-band management, you avoid that whole problem. And it's clear what you get and that you need to protect the management access. Not saying it can't be done, or there is no use-case for it, but you double your security hardening efforts (and need additional cabling, switches, etc).

To repeat, personal opinion.
