CHAPTER 16: SNMP

SNMP

SNMP user - A person for which an SNMP management operation is performed. The user is the person on a remote SNMP engine who receives the information.

SNMP view - A mapping between SNMP objects and the access rights available for those objects. An object can have different access rights in each view. Access rights indicate whether the object is accessible by either a community string or a user.

Write view - A view name (not to exceed 64 characters) for each group that defines the list of object identifiers (OIDs) that are able to be created or modified by users of the group.
