Generic traps Setting up the switch SNMP connection to an existing managed network allows the network system administrator to receive the following generic traps. coldStart indicates that the agent has reinitialized itself such that the agent configuration might be altered. This also indicates that the switch has restarted. linkDown indicates that an IP interface (Ethernet, loop back, or embedded N_Port) has gone down and is not available. linkUp indicates that an IP interface (Ethernet, loop back, or embedded N_Port) has become available. Note: linkUp and linkDown traps are not associated with removing or adding an Ethernet cable. This is strictly a driver indication that the interface is configured, operational, and available and does not necessarily mean that the physical network cable is affected. authenticationFailure indicates that the agent has received a protocol message that is not properly authenticated. This trap, by default, is disabled but can be enabled using the command agtcfgSet, or by setting the MIB-II variable snapEnableAuthenTraps to enabled (1). Enterprise specific traps Four Enterprise specific traps are supported. swFault Indicates that the diagnostics detect a fault with the switch. swSensorScn Indicates that an environment sensor changes its operational state. For example, a fan stops working. The VarBind in the trap data unit contains the corresponding instance of the sensor status. swFCPortScn A notification that a fibre-channel port changes its operational state. For example, the fibre-channel port goes from online to offline. The VarBind in the trap data unit contains the corresponding instance of the port operational status. swEventTrap A notification that an event has occurred and the event severity level is at or below the value set in the variable, swEventTrapLevel. See "Agent configuration" on page 78. The VarBind in the trap data unit contains the corresponding instance of the event index, time information, event severity level, the repeat count, and description. | swFabricWatchTrap | This is sent by fabric watch about an event to be monitored. | swTrackChangesTrap | Sent for tracking login, logout, and configuration changes. | Note: SNMP swFCPortScn traps are generated on GBIC insertion and | removal even though the state remains offline.

Generic traps
Setting up the switch SNMP connection to an existing managed network allows the
network system administrator to receive the following generic traps.
coldStart
indicates that the agent has reinitialized itself such that the agent
configuration might be altered. This also indicates that the switch has
restarted.
linkDown
indicates that an IP interface (Ethernet, loop back, or embedded N_Port)
has gone down and is not available.
linkUp
indicates that an IP interface (Ethernet, loop back, or embedded N_Port)
has become available.
Note:
linkUp and linkDown traps are not associated with removing or
adding an Ethernet cable. This is strictly a driver indication that the
interface is configured, operational, and available and does not
necessarily mean that the physical network cable is affected.
authenticationFailure
indicates that the agent has received a protocol message that is not
properly authenticated. This trap, by default, is disabled but can be enabled
using the command
agtcfgSet
, or by setting the MIB-II variable
snapEnableAuthenTraps
to enabled (1).
Enterprise specific traps
Four Enterprise specific traps are supported.
swFault
Indicates that the diagnostics detect a fault with the switch.
swSensorScn
Indicates that an environment sensor changes its operational state. For
example, a fan stops working. The VarBind in the trap data unit contains the
corresponding instance of the sensor status.
swFCPortScn
A notification that a fibre-channel port changes its operational state. For
example, the fibre-channel port goes from online to offline. The VarBind in
the trap data unit contains the corresponding instance of the port
operational status.
swEventTrap
A notification that an event has occurred and the event severity level is at
or below the value set in the variable,
swEventTrapLevel
. See “Agent
configuration” on page 78. The VarBind in the trap data unit contains the
corresponding instance of the event index, time information, event severity
level, the repeat count, and description.
swFabricWatchTrap
This is sent by fabric watch about an event to be monitored.
swTrackChangesTrap
Sent for tracking login, logout, and configuration changes.
Note:
SNMP swFCPortScn traps are generated on GBIC insertion and
removal even though the state remains offline.
