Traps
Functionality
The trap generation by the SNMP agent in a TXPORT unit is enabled by
configuring the Managers Machine IP address (any machine where he wants the
traps to be sent) in the respective MultiPro Unit Configuration for SNMP. By
default, this address is 0.0.0.0 in the configuration and then, no traps are generated.
Configuring an address in the SNMP configuration, enables all the traps
generation. Particular types of traps cannot be enabled or disabled. It is all or
nothing. Also, there is no provision to enable or disable particular traps by the SET
command.
Miscellaneous
Trap Behaviors
In a multicard chassis, if the traps are enabled and the unit is powered on, each
line module in the chassis sends a COLD START trap to the designated manager
machine. Instead of one trap for the cabinet, each line module sends its own trap.
If a frame relay port is configured as ~Network~+ and the modems signals are
present, the port generates LINKUP and LINKDOWN traps periodically. The
transition of a frame relay port from inactive to active generates the following
traps: one LINK UP TRAP, one DLCI state change trap for each DCLI on the port
and finally, one X25RESTART TRAP for each DLCI if the PLP stack is used. This
means a lot of traps are sent to the designated system. This behaviour can be
modified in the unit or management system to suit user needs.
