Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.57.1.12.1.1.4
snmpwalk -v2c -c public <target> Unisphere-Data-QoS-MIB::usdQosOutYellowPacketsSchedulerDrops

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.57.1.12.1.1.4.1
snmpget -v2c -c public <target> Unisphere-Data-QoS-MIB::usdQosOutYellowPacketsSchedulerDrops.1
