h3cDot11PreambleLen
Module: A3COM-HUAWEI-DOT11-CFG-MIB
OID (symbolic): A3COM-HUAWEI-DOT11-CFG-MIB::h3cDot11PreambleLen
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.75.4.3.2.1.7
Node type: OBJECT-TYPE
Type: H3cDot11PreambleType
Access: read-write
Description: Represents whether use long or short preamble for 802.11 MAC frame. When h3cDot11CfgRadioType is either dot11b or dot11g, then value for h3cDot11PreambleLen will be valid. Othwise, the value for it will be invalid.
What is h3cDot11PreambleLen?
This OID determines whether the radio uses short or long preamble format in 802.11b/g frames. Short preamble improves throughput on modern networks; long preamble provides backward compatibility with older devices. A value of 'short' on modern APs sacrifices compatibility to gain roughly 7% more bandwidth.
