◆
Trap Link-up and Link-down - Issues a notification message
whenever a port link is established or broken. (Default: Enabled)
◆
Trap Inform Mode - Enables or disables sending notifications as
inform messages. Note that this option is only available for version 2c
and 3 hosts. (Default: traps are used)
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.
◆
Trap Inform Timeout - The number of seconds to wait for an
acknowledgment before resending an inform message. (Range: 0-2147
seconds; Default: 1 second)
◆
Trap Inform Retry Times - The maximum number of times to resend
an inform message if the recipient does not acknowledge receipt.
(Range: 0-255; Default: 5)
◆
Trap Probe Security Engine ID (SNMPv3) - Specifies whether or not
to use the engine ID of the SNMP trap probe in trap and inform
messages. (Default: Enabled)
◆
Trap Security Engine ID (SNMPv3) - Indicates the SNMP trap security
engine ID. SNMPv3 sends traps and informs using USM for
authentication and privacy. A unique engine ID for these traps and
informs is needed. When “Trap Probe Security Engine ID” is enabled,
the ID will be probed automatically. Otherwise, the ID specified in this
field is used. (Range: 10-64 hex digits, excluding a string of all 0’s or all
F’s)

The Trap Probe Security Engine ID must be disabled before an
engine ID can be manually entered in this field.
◆
Trap Security Name (SNMPv3) - Indicates the SNMP trap security
name. SNMPv3 traps and informs use USM for authentication and
privacy. A unique security name is needed when SNMPv3 traps or
informs are enabled.

To select a name from this field, first enter an SNMPv3 user with the
same Trap Security Engine ID in the SNMPv3 Users Configuration menu
(see “Configuring SNMPv3 Users” on page 137 ).
