apWMMBssParamAIFSN
Module: CTRON-AP3000-MIB
OID (symbolic): CTRON-AP3000-MIB::apWMMBssParamAIFSN
OID (numeric): 1.3.6.1.4.1.52.4.13.23.2.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This attribute shall specify the number of slots, after a SIFS duration, that the QSTA, for a particular AC, shall sense the medium idle either before transmitting or executing a backoff.
What is apWMMBssParamAIFSN?
This read-write integer (1-15) sets the number of idle slot times, after a SIFS gap, that a non-AP QSTA must sense the medium as idle before transmitting or running backoff for a given Access Category. A lower AIFSN lets that traffic class access the channel sooner than classes with a higher value, which is the core mechanism WMM uses to prioritize traffic. Reducing AIFSN on the voice AC's BSS parameter is a common way to shave milliseconds of contention delay off VoIP packets.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.13.23.2.1.4 snmpwalk -v2c -c public <target> CTRON-AP3000-MIB::apWMMBssParamAIFSN
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.13.23.2.1.4.1 snmpget -v2c -c public <target> CTRON-AP3000-MIB::apWMMBssParamAIFSN.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.13.23.2.1.4.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> apWMMBssParamAIFSN.1
