Trap Receivers and Authentication Traps
Trap Features
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.
Note Fixed or "Well-Known" Traps: The Series 2500 switches automatically send
fixed traps (such as "coldStart", "warmStart", "linkDown", and "linkUp") to trap
receivers using a public community name. These traps cannot be redirected
to other communities. Thus, if you change or delete the default public com-
munity 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. The switch
can be configured to also send event log messages as traps if the following
opotions are used with the snmp-server host command:
