Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.4.3.1.16 snmpwalk -v2c -c public <target> Wellfleet-ASYNC-MIB::wfAsyncTxUnderFlows
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.4.3.1.16.1 snmpget -v2c -c public <target> Wellfleet-ASYNC-MIB::wfAsyncTxUnderFlows.1
