These values display for ipAddressTable objects using the snmpwalk command.There are several UNIX SNMP commands that read data.• Read the value of a single managed object.snmpget -v version -c community agent-ip {identifier.instance | descriptor.instance}• Read the value of the managed object directly below the specified object.snmpgetnext -v version -c community agent-ip {identifier.instance | descriptor.instance}• Read the value of many objects at once.snmpwalk -v version -c community agent-ip {identifier.instance | descriptor.instance}Examples of Reading the Value of Managed ObjectsIn the following example, the value “4” displays in the OID before the IP address for IPv4. For an IPv6 IP address, a value of “16” displays.> snmpget -v 2c -c mycommunity 10.11.131.161 sysUpTime.0DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (32852616) 3 days, 19:15:26.16> snmpget -v 2c -c mycommunity 10.11.131.161 .1.3.6.1.2.1.1.3.0Simple Network Management Protocol (SNMP) 791
