There are three types of views:

Read Views Allow read-only access to a specified list of Object IDs (OIDs) in the MIB tree

Write Views Allow read-write access to a specified list of OIDs in the MIB tree

Notify Views Allow SNMP notifications from a specified list of OIDs to be sent

Each view consists of a list of OIDs in the MIB tree. This list can be created using multiple snmp-server view commands to either add OIDs to the list or exclude OIDs from a list of all of the OIDs in the Branch Gateway’s MIB tree. You can use wildcards to include or exclude an entire branch of OIDs in the MIB tree, using an asterisk instead of the specific node.
