Configuring the Accounting Server
You can configure up to two AAA accounting servers. Automatic failover functionality is provided if
you have two accounting servers configured. In this case, if the first server is unreachable, the accounting
information is sent the second server. If both accounting servers are unreachable, accounting records are
cached until a server becomes available. If a server cannot be reached before the cache is full, the oldest
accounting packets are dropped to make room for the new packets.
Because the configuration of the AAA accounting server is completely independent of the AAA
authentication server, you can configure the AAA accounting server to be on the same or different
machine from the AAA authentication server.
If you use a syslog server, it is not affected by the AAA configuration and continues to use the existing
user interfaces. When the RADIUS server sends AAA accounting information to a syslog server, it is
normalized into a single string before being recorded. If no syslog server is defined, the AAA accounting
logs are recorded by the syslog server running locally on Cisco Unity Express.
For an accounting server, you can configure the following information used to log into the server:
• Server IP address or DNS name
• Port number used
• Cryptographic shared secret and security credentials
• Number of login retries
• Length of login timeout
Note Only RADIUS servers are supported.
