topic Change DHCP Option 43; and in Wireless

Global controller name/ip up

How can I update/change globally all host controller name/IP's to all attached AP's?

I'm going to turn off the 5508 and turn on the 5520.. new name/IP

The AP's will find their new target via DNS, but I suspect that will either leave the HA fields empty or pointing to the old targets.

Darn, we did not cover that in Prime class.

Enable DHCP Option 43, clear the DHCP leases and reboot the APs.

I do this all the time. A lot faster, in my opinion, to put all the AP names in an Excel spreadsheet and run a formula to populate the command. It can be done in about 2 minutes. Max.
