bsnGlobalDot11aFragmentationThreshold
Module: AIRESPACE-WIRELESS-MIB
OID (symbolic): AIRESPACE-WIRELESS-MIB::bsnGlobalDot11aFragmentationThreshold
OID (numeric): 1.3.6.1.4.1.14179.2.3.3.2.14
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This attribute shall specify the current maximum size, in octets, of the MPDU that may be delivered to the PHY. An MSDU shall be broken into fragments if its size exceeds the value of this attribute after adding MAC headers and trailers. MSDU or MMPDU shall be fragmented when the resulting frame has an individual address in the Address1 field, and the length of the frame is larger than this threshold. The default value for this attribute shall be the lesser of 2346 or the aMPDUMaxLength of the attached PHY and shall never exceed the lesser of 2346 or the aMPDUMaxLength of the attached PHY. The value of this attribute shall never be less than 256.
What is bsnGlobalDot11aFragmentationThreshold?
Specifies the maximum MPDU size in octets for the 802.11a radio; any MSDU larger than this value will be broken into smaller fragments before transmission. Lowering this threshold can improve reliability in noisy RF environments at the cost of overhead.
