Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.33.13.1.18.1.9
snmpwalk -v2c -c public <target> XYPLEX-CHARACTER1-MIB::basicSerialPortBackwardSwitch

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.33.13.1.18.1.9.1
snmpget -v2c -c public <target> XYPLEX-CHARACTER1-MIB::basicSerialPortBackwardSwitch.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.33.13.1.18.1.9.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> basicSerialPortBackwardSwitch.1
