Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.10.102.1.3.10 snmpwalk -v2c -c public <target> CISCO-IETF-DHCP-SERVER-MIB::cDhcpv4CountInvalids
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9.10.102.1.3.10.1 snmpget -v2c -c public <target> CISCO-IETF-DHCP-SERVER-MIB::cDhcpv4CountInvalids.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cDhcpv4CountInvalids.1
