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 can use either SNMPv1 traps or SNMPv2c notifications to send information from an agent to
the network manager. The terms trap and notification are used interchangeably in this context.
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 target 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>]}
To delete a single target address or all target addresses, use the following command:
configure snmpv3 delete target-addr [{[[hex <hex_addr_name>] | <addr_name>]} | all]
Target Parameters
Target parameters specify the MP model, security model, security level, and user name (security name)
used for messages sent to the target address. See
“Message Processing” on page 86 and “Users, Groups,
and Security” on page 87 for more details on these topics. In addition, the target parameter name used
for a target address points to a filter profile used to filter notifications. When you specify a filter profile,
