Supported Mibs; Configuring Basic Snmp Functions - 3Com 4500 Configuration Manual

Set the permission for a community to access an MIB object to be read-only or read-write.
Communities with read-only permissions can only query the switch information, while those with
read-write permission can configure the switch as well.
Set the basic ACL specified by the community name.

Supported MIBs

An SNMP packet carries management variables with it. Management variable is used to describe the
management objects of a switch. To uniquely identify the management objects of the switch, SNMP
adopts a hierarchical naming scheme to organize the managed objects. It is like a tree, with each tree
node representing a managed object, as shown in
identified by a path starting from the root.

MIB describes the hierarchical architecture of the tree and it is the set defined by the standard variables
of the monitored network devices. In the above figure, the managed object B can be uniquely identified
by a string of numbers {1.2.1.1}. The number string is the object identifier (OID) of the managed object.

Configuring Basic SNMP Functions

SNMPv3 configuration is quite different from that of SNMPv1 and SNMPv2c. Therefore, the
configuration of basic SNMP functions is described by SNMP versions, as listed in the following two
tables.
Follow these steps to configure basic SNMP functions (SNMPv1 and SNMPv2c):
To do...
Enter system view
Enable SNMP agent
Set system information, and specify
to enable SNMPv1 or SNMPv2c on
the switch

You can enable SNMP

commands used to
configure SNMP agent.

By default, the contact
information for system
maintenance is " 3Com
