Specifying Trap
Managers
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.
Command Usage
◆ 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:
1. Enable the SNMP agent (page 440).
2. Create a view with the required notification messages (page 444).
3. Configure the group (matching the community string specified on the
Configure Trap - Add page) to include the required notify view (page 447).
4. Enable trap informs as described in the following pages.
To send an inform to a SNMPv3 host, complete these steps:
1. Enable the SNMP agent (page 440).
2. Create a remote SNMPv3 user to use in the message exchange process
(page 453). 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 remote user, and default settings for the read, write, and notify
view.
3. Create a view with the required notification messages (page 444).
4. Create a group that includes the required notify view (page 447).
5. Enable trap informs as described in the following pages.
Parameters
These parameters are displayed:
SNMP Version 1
◆ IP Address – IPv4 or IPv6 address of a new management station to receive
notification message (i.e., the targeted recipient).
◆ Version – Specifies whether to send notifications as SNMP v1, v2c, or v3 traps.
(Default: v1)
