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: Specifies a view name, a string of 1 to 32 characters.
oid-tree: Specifies a MIB subtree by its root node's OID (for example, 1.3.6.1.2.1.1) or object name
(for example, system), a case-sensitive string of 1 to 255 characters. An OID is a dotted numeric
string that uniquely identifies an object in the MIB tree.
mask mask-value: Sets a MIB subtree mask, a hexadecimal string. Its length is an even number in
the range of 2 to 32.
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 most recent 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 1.3.6.1.2.1) subtree in the mibtest view and exclude the system subtree
from this view.
<Sysname> system-view
[Sysname] snmp-agent sys-info version v1
[Sysname] snmp-agent mib-view included mibtest 1.3.6.1.2.1
[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.
