Cisco WAP571/E Administration Guide
• Key 1—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 WAP device and on
your RADIUS server. The text you enter is shown as asterisks to prevent
others from seeing the RADIUS key as you type.
• Key 2 to Key 4—The RADIUS key associated with the configured backup
RADIUS servers. The server at Server IP (IPv6) Address 2 uses Key 2, the
server at Server IP (IPv6) Address 3 uses Key 3, and so on.
• Enable RADIUS Accounting—Tracks and measures the resources a
particular user has consumed such as system time, amount of data
transmitted and received, and so on.
If you enable RADIUS accounting, it is enabled for the primary RADIUS
server and all backup servers.
• Active Server—Enables the administrative selection of the active RADIUS
server, rather than having the WAP device attempt to contact each
configured server in sequence and choose the first server that is up.
• Broadcast Key Refresh Rate—The interval at which the broadcast (group)
key is refreshed for clients associated with this VAP.
The default is 300 seconds. The valid range is from 0 to 86400 seconds. A
value of 0 indicates that the broadcast key is not refreshed.
• Session Key Refresh Rate—The interval at which the WAP device
refreshes session (unicast) keys for each client associated with the VAP.
The valid range is from 30 to 86400 seconds. A value of 0 indicates that the
session key is not refreshed.
The Wireless Multicast Forwarding provides an efficient way to forward the
multicast traffic on the wireless medium and over comes the multicast
transmission issues on WLAN using the repeated unicast of multicast frames.
It uses IGMP frames to keep track of participating group members and multicast
packets are transmitted only to the interested members after unicast MAC
conversion.
