One of the issues I found with having H3C/3Com now HP products over the last few years is the lack of support for scenarios that are described but never documented. While desciption  of features exist configuration guides or FAQ seem non-existent. I recently purchased a S7500 controller blade at work for our new core to move over our existing 7760 series Access Points from 3CRUS2475 switches over to a more robust solution designed to handle our  70+ APs. The first step is to update the managed firmware in the device from the firmware that ships meant for management by the Unified Wireless Switch 3CRUS2475 to the H3C fit managed mode. I just wanted to take this time to document the differnet ways it seem you can configure these to discover the Access Controller.

  1. IPv4 Broadcast Discovery 255.255.255.255 from/to port 12223:  3 packets detailing that it is a discovery packet and the model and serial number of the device.
  2. DNS Discovery for hostname 3ComWLC: 1 DNS request stops if no name found
  3. IPv6 Multicast Discovery FF02:1 from/to port 12223 : 3 Packets again detailing that it is a discovery packet and the model and serial number of the device.

This then repeats if  no controllers are found. The additional options for manually configuring the device exist:

Log in via the console port  or telnet in password is “h3capadmin”

<7760_2750> sys

[7760_2750] wlan ac ip “ip address”

or

[7760_2760] wlan ac ipv6 “ipv6 address”

[7760_2750] quit

<7760_2750> save

Hope this helps….
