Read Managed Object Values - Dell Force10 S4810P Configuration Manual

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,
representing a type of internet address. These values display for ipAddressTable objects using the
command.
snmpwalk
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.
