5. The RF Status section displays the following read-only RF radio signal information for
associated APs and radios:

Viewing switch port information
The Port screen displays configuration, runtime status, and statistics of the ports on the switch.
NOTE
The ports available on the Brocade Mobility RFS7000-GR Controller are: ge1, ge2, ge3, ge4 and
me1
Avg. Bit Speed 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.
% Non-unicast pkts 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 a greater chance of causing collisions.
Avg Signal 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.
Avg Noise 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.
Avg SNR (dB) Displays the average Signal to Noise Ratio (SNR) in decibels for all MUs associated
with the switch. The Signal to Noise Ratio is an indication of overall RF
performance on the wireless network.
Average Number of
Retries 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
linked back to the AP.
% Gave Up Pkts 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
% Non-decryptable Pkts 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 a misconfigured static
key.
