nbsBackOffMode
Module: GSWITCH-MIB
OID (symbolic): GSWITCH-MIB::nbsBackOffMode
OID (numeric): 1.3.6.1.4.1.629.2.3.16
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The CSMA/CD normal Back of mode multiples the back-off time frame after each each collision. In aggressive mode it stops to multiply after the second time. This way it will have an advantage of any other NIC who uses normal back-off mode.
What is nbsBackOffMode?
This read-write OID selects the CSMA/CD collision back-off algorithm: 'normal' keeps doubling the back-off window after every collision, while 'aggressive' stops doubling after the second collision, giving this switch's ports a transmission edge over NICs using standard back-off. An admin would avoid aggressive mode on a shared/regulated network since it can be seen as unfair to other devices.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.629.2.3.16 snmpwalk -v2c -c public <target> GSWITCH-MIB::nbsBackOffMode
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.629.2.3.16.1 snmpget -v2c -c public <target> GSWITCH-MIB::nbsBackOffMode.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.629.2.3.16.1 i <value>
