RADIUS Authorization and Accounting Support
The CCU now supports RADIUS authorization and accounting. When enabled, the CCU
generates a RADIUS access-request message for each registered EUM on a periodic basis.
The responses from the RADIUS server are used to maintain the authorization table.
If accounting is enabled, the CCU sends periodic accounting updates to the RADIUS server
for each registered EUM. These updates contain the Input and Output Packet and Byte counts
for each EUM (Input is received from EUM, Output is transmitted to EUM).
The following new RADIUS commands are available on the CCU:
• auth radius disable
• auth radius enable
• auth radius primary
• auth radius secondary
• auth radius period
• auth radius acct disable
• auth radius acct enable
• stats auth
All RADIUS commands take effect immediately (without a reboot).
RADIUS settings are stored in basic.cfg, with the shared secret passwords securely
encrypted.
The authorization table has a new column indicating whether an entry was entered from the
CLI (static) or by a RADIUS response (radius). Non-response to RADIUS requests following
the first is indicated in this column as well.
Air Table Accounting Info
The Tx-octet, Tx-packet, Rx-octet and Rx-packet counts maintained for RADIUS accounting
are also printed out in the registration table as shown below:

Low Impact Polling
The polling algorithm has been modified to reduce the number of CCU transmissions under
low load—and therefore the amount of time the spectrum is occupied—without reducing
capacity or affecting latency. This improvement is achieved primarily by eliminating redundant
random access polls.
