A trap receiver is a management station designated by the switch to receive SNMP traps sent from the switch. An authentication trap is a specialized SNMP trap sent to trap receivers when an unauthorized management station tries to access the switch.

N o t e

 

Fixed or "Well-Known" Traps: The switch automatically sends fixed traps

 

 

(such as "coldStart", "warmStart", "linkDown", and "linkUp") to trap receivers

 

 

using the public community name. These traps cannot be redirected to other

 

 

communities. Thus, if you change or delete the default public community

 

 

name, these traps will be lost.

 

 

 

Thresholds: The switch automatically sends all messages resulting from

 

 

thresholds to the network management station(s) that set the thresholds,

 

 

regardless of the trap receiver configuration.

 

 

 

In the default configuration, there are no trap receivers configured, and the

 

 

 

 

authentication trap feature is disabled. From the CLI you can configure up to

 

 

ten SNMP trap receivers to receive SNMP traps from the switch. As an option,

 

 

you can also configure the switch to send Event Log messages as traps. CLI:
