mib-view view-name: S Specifies MIB objects that the NMS can access, view-name represents the
MIB view name, a string of 1 to 32 characters. If no keyword is specified, the default view is ViewDefault
(The view created by the system after SNMP agent is enabled).
Description
Use the snmp-agent community command to create a new SNMP community. Parameters to be
configured include access right, community name, ACL, and accessible MIB views.
Use the undo snmp-agent community command to delete a specified community.
This command can be applied in SNMPv1 and v2c networking environments.
A community is composed of NMSs and SNMP agents, and is identified by the community name, which
functions as a password. In a community, when devices communicate with each other, they use
community name for authentication. The NMS and the SNMP agent can access each other only when
they are configured with the same community name. Typically, public is used as the read-only
community name, and private is used as the read and write community name. For security purposes,
you are recommended to configure a community name other than public and private.
The keyword acl specifies that only the NMS with a qualified IP address can access the agent.
The argument community-name specifies the community name used by the NMS when it accesses
the agent.
The keyword mib-view specifies the MIB objects which the NMS can access.
The keywords read and write specify the access type.

Set the SNMP version on the NMS to SNMPv1 or SNMPv2c

ViewDefault view on the device

1.1.1.1 to configure the values of the agent MIB objects by using this community name; other NMSs are
not allowed to perform the write operations by using this community name.
