Simple Network Management Protocol (SNMP) | 889
Read 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 Force10 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.
In the following figure, the value “4” displays in the OID before the IP address for IPv4. For an IPv6 IP
address ), a value of “16” displays.
There are several UNIX SNMP commands that read data:
Configure the user with a secure
authorization password and
privacy password.
snmp-server user name group-name {oid-tree}
auth md5 auth-password priv des56 priv password
CONFIGURATION
Configure an SNMPv3 view. snmp-server view view-name oid-tree {included |
excluded}
CONFIGURATION
Task Command
Read the value of a single managed object,
as shown in Figure 45-3.
snmpget -v version -c community agent-ip {identifier.instance |
descriptor.instance}
Figure 45-3. Reading the Value of a Managed Object
Read the value of the managed object
directly below the specified object, as
shown in Figure 45-4.
snmpgetnext -v version -c community agent-ip {identifier.instance |
descriptor.instance}
