Cisco Small Business WAP371 Wireless Access Point Administration Guide
• Frame-burst Support—Generally enabling Frame-burst support improves the radio
performance in the downstream direction.
• Fixed Multicast Rate—The transmission rate in Mbps for broadcast and multicast
packets. This setting can be useful in an environment where wireless multicast video
streaming occurs, provided the wireless clients are capable of handling the configured
rate.
When Auto is selected, the WAP device chooses the best rate for the associated clients.
The range of valid values is determined by the configured radio mode.
• Legacy Rate Sets—Rates are expressed in megabits per second.
Supported Rate Sets indicate rates that the WAP device supports. You can check
multiple rates (check a box to select or deselect a rate). The WAP device automatically
chooses the most efficient rate based on factors such as error rates and the distance of
client stations from the WAP device.
Basic Rate Sets indicate rates that the WAP device advertises to the network for the
purposes of setting up communication with other access points and client stations on the
network. It is generally more efficient to have a WAP device broadcast a subset of its
supported rate sets.
• 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 are 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 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. By default,
TSPEC mode is off. 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.
