Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2021.4.19 snmpwalk -v2c -c public <target> UCD-SNMP-MIB::memAvailSwapX
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2021.4.19.1 snmpget -v2c -c public <target> UCD-SNMP-MIB::memAvailSwapX.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> memAvailSwapX.1
