Radio
Cisco Small Business WAP121 and WAP321 Wireless-N Access Point with PoE
The MCS settings can be configured only if the radio mode includes 802. 1 1n
support.
• Broadcast/Multicast Rate Limiting—Multicast and broadcast rate limiting
can improve overall network performance by limiting the number of packets
transmitted across the network.
By default the Multicast/Broadcast Rate Limiting option is disabled. Until you
enable Multicast/Broadcast Rate Limiting, these fields will be disabled:
• Rate Limit—The rate limit for multicast and broadcast traffic. The limit
should be greater than 1, but less than 50 packets per second. Any traffic
that falls below this rate limit will always conform and be transmitted to the
appropriate destination.
The default and maximum rate limit setting is 50 packets per second.
• Rate Limit Burst—An amount of traffic, measured in bytes, which is the
traffic allowed to pass as a temporary burst even if it is above the defined
maximum rate.
The default and maximum rate limit burst setting is 75 packets per second.
• TSPEC Mode—Regulates the overall TSPEC mode on the WAP device. The
options are:
- On — The WAP device handles TSPEC requests according to the
TSPEC settings you configure on the Radio page. Use this setting if the
WAP device handles traffic from QoS-capable devices, such as a Wi-Fi
CERTIFIED phone.
- Off — The WAP device ignores TSPEC requests from client stations.
Use this setting if you do not want to use TSPEC to give QoS-capable
devices priority for time-sensitive traffic.
• TSPEC Voice ACM Mode —Regulates mandatory admission control (ACM)
for the voice access category. The options are:
- On — A station is required to send a TSPEC request for bandwidth to the
WAP device before sending or receiving a voice traffic stream. The WAP
device responds with the result of the request, which includes the
allotted medium time if the TSPEC was admitted.
- Off — A station can send and receive voice priority traffic without
requiring an admitted TSPEC; the WAP device ignores voice TSPEC
requests from client stations.
