I have installed and configured these two new 5520s for my client. They are to be redundant AP fail-overs for some 5508s. We are seeing Mobility Group failures (Status: Control and Data Path Down). I have asked that the following ports be verified open:
- UDP 16666 for tunnel control traffic
- IP protocol 97 for user data traffic
- UDP 161 and 162 for SNMP
I have verified I can do a standard ping between controllers.
From the 5520 with IP X.X.X.X:
