Sets the maximum percentage of client retransmissions a radio can 
experience before RF Auto-Tuning considers changing the channel on the 
radio. A high percentage of retransmissions is a symptom of interference 
on the channel.

 — List of ports connected to the MAP access points on 

which to set the channel.

„

 

 — Number of a Distributed MAP on which to set the 

channel.

„

— Sets the maximum retransmissions for radios configured 

by the MAP configuration profile. (See set dap auto on page 325.)

„

 — Radio 1 of the MAP.

„

 — Radio 2 of the MAP. (This option does not apply to 

single-radio models.)

„

 — Percentage of packets that can result in 

retransmissions without resulting in a channel change. You can 
specify from 1 to 100. 

Defaults — The default is 10 percent. 

Access — Enabled.

History —Introduced in MSS Version 3.0. Option auto added for 
configuration of the MAP configuration profile.

Usage — A retransmission is a packet sent from a client to a MAP radio 
that the radio receives more than once. This can occur when the client 
does not receive an 802.11 acknowledgement for a packet sent to the 
radio. 

If the radio receives only a single copy of a packet that is transmitted 
multiple times by a client, the packet is not counted by the radio as a 
retransmission. For example, if a packet is corrupted and the radio does 
not receive it, but the second copy of the packet does reach the radio, 
the radio does not count the packet as a retransmission since the radio 
received only one recognizable copy of the packet.
