Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.25506.2.40.2.3.2.1.2 snmpwalk -v2c -c public <target> HH3C-IF-EXT-MIB::hh3cIfMtu
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.25506.2.40.2.3.2.1.2.1 snmpget -v2c -c public <target> HH3C-IF-EXT-MIB::hh3cIfMtu.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.25506.2.40.2.3.2.1.2.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> hh3cIfMtu.1
