SAN256N director system traps
A trap, as defined for use in the SAN256N director, is a configurable software function
that will send out an alarm when a particular event or condition occurs. Traps are used to
notify an end node, either an Ethernet or Fibre Channel node, that a particular event has
occurred.
There are a number of traps resident on the Director, some of which can be controlled
by the Administrator. If a trap is enabled and the corresponding event occurs, an alarm
message with all corresponding information will be constructed to report the trap.
There are several different trap types:
• Chassis hardware traps, which indicate a chassis hardware problem such as a power
supply or fan failure
• Fabric traps, which indicate a problem in the fabric, most likely between the director
and one or more N/NL_Ports
• Internal hardware traps, which indicate a potentially serious internal hardware error
condition relating to the routing of frames within the director
• Switch traps, which indicate director-specific actions
• Port traps, which indicate port-specific actions
The following table lists the possible traps:
