| Basic Administration Protocols

Simple Network Management Protocol

Use the Administration > SNMP (Configure Trap) page to specify the host

devices to be sent traps and the types of traps to send. Traps indicating

status changes are issued by the switch to the specified trap managers.

You must specify trap managers so that key events are reported by this

switch to your management station (using network management

software). You can specify up to five management stations that will receive

authentication failure messages and other trap messages from the switch.

Notifications are issued by the switch as trap messages by default. The

recipient of a trap message does not send a response to the switch.

Traps are therefore not as reliable as inform messages, which include a

request for acknowledgement of receipt. Informs can be used to ensure

that critical information is received by the host. However, note that

informs consume more system resources because they must be kept in

memory until a response is received. Informs also add to network

traffic. You should consider these effects when deciding whether to

issue notifications as traps or informs.

To send an inform to a SNMPv2c host, complete these steps:

Enable the SNMP agent

Create a view with the required notification messages

Configure the group (matching the community string specified on

the Configure Trap - Add page) to include the required notify view

Enable trap informs as described in the following pages.

To send an inform to a SNMPv3 host, complete these steps:

Enable the SNMP agent

Create a local SNMPv3 user to use in the message exchange

495). If the user specified in the trap configuration

page does not exist, an SNMPv3 group will be automatically created

using the name of the specified local user, and default settings for

the read, write, and notify view.

Create a view with the required notification messages

Create a group that includes the required notify view

Enable trap informs as described in the following pages.
