Cisco WAP131 and WAP351 Administration Guide
An SNMP MIB view is a family of view subtrees in the MIB hierarchy. A view
subtree is identified by the pairing of an Object Identifier (OID) subtree value with a
bit string mask value. Each MIB view is defined by two sets of view subtrees,
included in or excluded from the MIB view. You can create MIB views to control the
OID range that SNMPv3 users can access.
The WAP device supports a maximum of 16 views.
These notes summarize some critical guidelines regarding SNMPv3 view
configuration. Please read all the notes before proceeding.
A MIB view called all is created by default in the system. This view contains all
management objects supported by the system.
By default, view-all and view-none SNMPv3 views are created on the WAP device.
These views cannot be deleted or modified.
To add and configure an SNMP view:
Select SNMP > Views.
Click Add to create a new row in the SNMPv3 Views table.
Check the box in the new row and click Edit:
• View Name—Enter a name that identifies the MIB view. View names can
contain up to 32 alphanumeric characters.
• Type—Choose whether to include or exclude the view subtree or family of
subtrees from the MIB view.
• OID—Enter an OID string for the subtree to include or exclude from the view.
For example, the system subtree is specified by the OID string.1.3.6.1.2.1.1.
• Mask—Enter an OID mask. The mask is 47 characters in length. The format
of the OID mask is xx.xx.xx (.)... or xx:xx:xx.... (:) and is 16 octets in length. Each
octet is two hexadecimal characters separated by either a period (.) or a
colon (:). Only hex characters are accepted in this field. For example, OID
mask FA.80 is 11111010.10000000.
A family mask is used to define a family of view subtrees. The family mask
indicates which subidentifiers of the associated family OID string are
significant to the family's definition. A family of view subtrees enables
efficient control access to one row in a table.
