Displays the average bit speed for the switch over last 30 seconds and 1 hour. Use
the average bit speed value to help determine overall network speeds and
troubleshoot network congestion.
Displays the percentage of non-unicast packets seen (received & transmitted) by
the switch over last 30 seconds and 1 hour. Non-unicast traffic includes both
multicast and broadcast traffic.
Broadcasted, multicasted, and flooded packets are sent over the air at the slowest
rate on every radio in the WLAN and therefore have a much larger airtime
utilization than unicast packets and a greater chance of causing collisions.
section displays the following read-only RF radio signal information for associated APs
Displays the average signal strength for MUs associated with the switch over the
last 30 seconds and 1 hour. Typically, the higher the signal, the closer the MU.
Displays the average RF noise for all MUs associated with the selected WLAN.
MU noise for the last 30 seconds is displayed in black and the number in blue
represents MU noise for the last hour. If MU noise is excessive, consider moving
the MU closer to the Access Port, or in area with less conflicting network traffic.
Excessive noise may also be an indication of network interference.
Displays the average Signal to Noise Ratio (SNR) for all MUs associated with the
switch. The Signal to Noise Ratio is an indication of overall RF performance on the
wireless network.
Errors field for read-only packet error and loss information for associated Access Ports and
Displays the average number of retries for all MUs associated with the switch.
The number in black represents average retries for the last 30 seconds and the
number in blue represents average retries for the last hour.
If the Average Number of Retries starts increasing, this indicates that MUs are not
getting a good link back to the AP.
Displays the percentage of packets which the switch gave up on for all MUs
associated with the switch. The number in black represents this statistic for the
last 30 seconds and the number in blue represents this statistic for the last hour.
If this field displays a non-zero number it indicates bad links causing packets to
the MUs.
Displays the percentage of undecryptable packets for all MUs associated with the
switch. The number in black represents undecryptable pkts for the last 30 seconds
and the number in blue represents undecryptable pkts for the last hour.
If this field displays a non-zero number it can indicate outside intrusion into the
network or an MU using incorrect cryptography such as a misconfigured static
key.
