generated by the switch. If no trap manager is defined, no traps are issued.

community string.
SNMPv3 Group
The group will be used in V3 access. In SNMP v3 group you can indicate
group name security model and group security
SNMPv3 View
V3 View only used on NNMP v3 .When the network management station visit
the SNMP agent, the V3 View is used to limit the privilege to visit the
Management Information Base. You can only view the MIB information (for
example: system name, interface) which included in the view you created.
Include/excluded indicate that the device feature OID include the Subtree ID or
not. View mask: A Subtree OID used with a View mask defines a view Subtree.
A View mask is in hexadecimal format. After it is converted to binary bits, each
bit corresponds to a node of the OID, where:
1
means full match, that is, the OID of the MIB object to be accessed must
be identical to the Subtree OID.
0
means wildcard match, that is, the OID of the MIB object to be accessed
can be different from the Subtree OID.
For example, provided the View mask 0xDB (11011011 in binary) and the
Subtree OID 1.3.6.1.6.1.2.1, their relationship is as shown as following. The
view determined by them includes all the nodes under the Subtree whose OID
is 1.3.*.1.6.*.2.1, where * represents any number.
