Reading Managed Object Values
You may only retrieve (read) managed object values if your management station is a member of the same community as the
SNMP agent.
Dell Networking supports RFC 4001, Textual Conventions for Internet Work Addresses that defines values representing a type
of internet address. 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}
In 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.0
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (32852616) 3 days, 19:15:26.16
> snmpget -v 2c -c mycommunity 10.11.131.161 .1.3.6.1.2.1.1.3.0
The following example shows reading the value of the next managed object.
> snmpgetnext -v 2c -c mycommunity 10.11.131.161 .1.3.6.1.2.1.1.3.0
SNMPv2-MIB::sysContact.0 = STRING:
> snmpgetnext -v 2c -c mycommunity 10.11.131.161 sysContact.0
The following example shows reading the value of many managed objects at one time.
> snmpwalk -v 2c -c public 10.11.198.100 .1.3.6.1.2.1.1
