Among all the actions you can see that the Trap is agent->manager, and Get and Set correspond to read and write of manager->agent respectively. The following is a page-by-page introduction in two configurations, v1/v2 and v3.
This page configures the master switch, SNMP version, location and contact information of the SNMP function. Selecting SNMPv1 or SNMPv2 here has no effect on subsequent page configuration. The location and contact information will be reflected in the manager's view. It is recommended to fill in according to the actual situation to facilitate subsequent management and transfer.
As a database, MIB (Management Information Base) needs to create views for managers with different levels of authority. MIB view is a subset of MIB. A MIB view is uniquely determined by the view name and MIB subtree. The view subtree is identified by the object identifier (OID) subtree value pairing of the bit string mask value. Each MIB view is defined by two sets of view subtrees, which can be included in this MIB view or excluded from the MIB view. A maximum of 5 views can be created here.
The view name is self-selected, and there is an All by default, which can be added as needed in the future.
VACM (View-based Access Control Model) using the community as a "password" Allow from the network up to the password holders of those of different views execute permission allows the work.
This page configures the destination (IP/port) of the alarm message.
Before the 3x.2.0.17 version, there may be an extra comma somewhere in the downloaded .txt file.
The main change is the VACM page, which improves the management and security of passwords and password holders, and the degree of freedom of password holders.
