Wireless Modifying Virtual Access Point Settings 4 Table 13 IEEE 802.1X Field RADIUS IP Address 1-3 Description Enter up to three IPv4 addresses to use as the backup RADIUS servers for this VAP. RADIUS Key RADIUS Key 1-3 Enable RADIUS Accounting If authentication fails with the primary server, each configured backup server is tried in sequence. Enter the RADIUS key in the text box. The RADIUS Key is the shared secret key for the global RADIUS server. You can use up to 63 standard alphanumeric and special characters. The key is case sensitive, and you must configure the same key on the access point and on your RADIUS server. The text you enter will be displayed as "*" characters to prevent others from seeing the RADIUS key as you type. Enter the RADIUS key associated with the configured backup RADIUS servers. The server at RADIUS IP Address-1 uses RADIUS Key-1, RADIUS IP Address-2 uses RADIUS Key-2, and so forth. Select this option to track and measure the resources a particular user has consumed such as system time, amount of data transmitted and received, and so forth. Broadcast Key Refresh Rate If you enable RADIUS accounting, it is enabled for the primary RADIUS server and all backup servers. Enter a value to set the interval at which the broadcast (group) key is refreshed for clients associated to this VAP. Session Key Refresh Rate The valid range is 0-86400 seconds. A value of 0 indicates that the broadcast key is not refreshed. Enter a value to set the interval at which the access point will refresh session (unicast) keys for each client associated to the VAP. The valid range is 0-86400 seconds. A value of 0 indicates that the broadcast key is not refreshed. Cisco AP 541N Dual-band Single-radio Access Point Quick Start Guide 68

RADIUS IP Address
1–3
Enter up to three IPv4 addresses to use as the backup
RADIUS servers for this VAP.
If authentication fails with the primary server, each
configured backup server is tried in sequence.
RADIUS Key
Enter the RADIUS key in the text box.
The
RADIUS Key
is the shared secret key for the
global RADIUS server. You can use up to 63 standard
alphanumeric and special characters. The key is case
sensitive, and you must configure the same key on the
access point and on your RADIUS server. The text you
enter will be displayed as "*" characters to prevent
others from seeing the RADIUS key as you type.
RADIUS Key 1–3
Enter the RADIUS key associated with the configured
backup RADIUS servers. The server at RADIUS IP
Address-1 uses RADIUS Key-1, RADIUS IP Address-2
uses RADIUS Key-2, and so forth.
Enable RADIUS
Accounting
Select this option to track and measure the resources
a particular user has consumed such as system time,
amount of data transmitted and received, and so forth.
If you enable RADIUS accounting, it is enabled for the
primary RADIUS server and all backup servers.
Broadcast Key
Refresh Rate
Enter a value to set the interval at which the broadcast
(group) key is refreshed for clients associated to this
VAP.
The valid range is 0–86400 seconds. A value of 0
indicates that the broadcast key is not refreshed.
Session Key Refresh
Rate
Enter a value to set the interval at which the access
point will refresh session (unicast) keys for each client
associated to the VAP.
The valid range is 0–86400 seconds. A value of 0
indicates that the broadcast key is not refreshed.
