Snmp-Agent Packet Max-Size - H3C S5830V2 Series Command Reference Manual

Default
The system creates the ViewDefault view when the SNMP agent is enabled. In this default MIB view, all
MIB objects in the iso subtree but the snmpUsmMIB, snmpVacmMIB, and snmpModules.18 subtrees are
accessible.
Views
System view
Predefined user roles
network-admin
Parameters
excluded: Denies access to any node in the specified MIB subtree.
included: Permits access to all the nodes in the specified MIB subtree.
view-name: Specify a view name, a string of 1 to 32 characters.
oid-tree: Specifies a MIB subtree by its root node's OID (for example 1.4.5.3.1) or object name (for
example, system). An OID is a dotted numeric string that uniquely identifies an object in the MIB tree.
Usage guidelines
A MIB view represents a set of MIB objects (or MIB object hierarchies) with certain access privilege. The
MIB objects included in the MIB view are accessible while those excluded from the MIB view are
inaccessible.
Each view-name oid-tree pair represents a view record. If you specify the same record with different MIB
subtree masks multiple times, the last configuration takes effect.
The system can store entries for up to 20 unique MIB view records. In addition to the four default MIB view
records, you can create up to 16 unique MIB view records. After you delete the default view with the undo
snmp-agent mib-view command, you can create up to 20 unique MIB view records.
Be cautious with deleting the default MIB view. The operation blocks the access to any MIB object on the
device from NMSs that use the default view.
Examples
# Include the mib-2 (OID 1.3.6.1) subtree in the mibtest view and exclude the system subtree from this
view.
<Sysname> system-view
[Sysname] snmp-agent mib-view included mibtest 1.3.6.1
[Sysname] snmp-agent mib-view excluded mibtest system
[Sysname] snmp-agent community read public mib-view mibtest
An SNMPv1 NMS in the public community can query the objects in the mib-2 subtree but not any object
(for example, the sysDescr or sysObjectID node) in the system subtree.
