Using SNMP
To define a view that includes the entire MIB-2, use the following subtree/mask:
1.3.6.1.2.1.1 / 1.1.1.1.1.0.0.0
which, on the command line, is:
1.3.6.1.2.1.1 / f8
When you create the MIB view, you can choose to include the MIB subtree/mask, or to exclude the MIB
subtree/mask. To create a MIB view, use the following command:
configure snmpv3 add mib-view {hex} <view name> subtree <object identifier> {/<subtree
mask>} {type [included | excluded]} {volatile}
Once the view is created, you can repeatedly use the command to
configure snmpv3 add mib-view
include and/or exclude MIB subtree/mask combinations to precisely define the items you wish to
control access to.
In addition to the user created MIB views, there are three default views. They are of storage type
permanent and cannot be deleted, but they can be modified. The default views are: defaultUserView,
defaultAdminView, and defaultNotifyView. To show MIB views, use the following command:
show snmpv3 mib-view {{hex} <view name> {subtree <object identifier>}}
To delete a MIB view, use the following command:
configure snmpv3 delete mib-view [all-non-defaults | {{hex} <view name> {subtree
<object identifier>}}]
MIB views which are being used by security groups cannot be deleted.

Notification

SNMPv3 notification is an enhancement to the concept of SNMP traps. Notifications are messages sent
from an agent to the network manager, typically in response to some state change on the agent system.
With SNMPv3, you can define precisely which traps you want sent, to which receiver by defining filter
profiles to use for the notification receivers.
To configure notifications, you will configure a target address for the process that receives the
notification, a target parameters name, and a list of notification tags. The target parameters specify the
security and message processing models to use for the notifications to the target. The target parameters
name also points to the filter profile used to filter the notifications. Finally, the notification tags are
added to a notification table so that any target addresses using that tag will receive notifications.
Target Addresses
A target address is similar to the earlier concept of a trap receiver. To configure a target address, use the
following command:
configure snmpv3 add target-addr {hex} <addr name> param {hex} <param name> ipaddress
<ip address> {transport-port <port>} {from <source IP address>} {tag-list {hex} <tag>,
{hex} <tag>, ...} {volatile}
In configuring the target address you will supply an address name that will be used to identify the
target address, a parameters name that will indicate the message processing model and security for the
messages sent to the target address, and the IP address and port for the receiver. The parameters name
also is used to indicate the filter profile used for notifications. The target parameters are discussed in the
section "Target Parameters" on page 62.
