Managing the Switch
After the view has been created, you can repeatedly use the configure snmpv3 add mib-view
command to include and/or exclude MIB subtree/mask combinations to precisely define the items you
want to control access to.
In addition to the user-created MIB views, there are three default views. These default views 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 <hex_view_name>] | <view_name>] {subtree
<object_identifier>}}
To delete a MIB view, use the following command:
configure snmpv3 delete mib-view [all-non-defaults | {[[hex <hex_view_name>] |
<view_name>] {subtree <object_identifier>}}]
MIB views that are used by security groups cannot be deleted.
SNMPv3 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 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
MP 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 <hex_addr_name] | <addr_name>] param [[hex
<hex_param_name] | <param_name>] ipaddress [[<ip_address> {<netmask>}] | <ip_address>]
{transport-port <port_number> {from <src_ip_address>} {tag-list <tag_list>} {volatile}
In configuring the target address you supply an address name that identifies the target address, a
parameters name that indicates the MP model and security for the messages sent to that 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 is discussed in “Target Parameters” next.
The from option sets the source IP address in the notification packets.
The tag-list option allows you to associate a list of tags with the target address. The tag defaultNotify
is set by default. Tags are discussed in the section “Notification Tags”.
To display target addresses, use the following command:
show snmpv3 target-addr {[[hex <hex_addr_name>] | <addr_name>]}
