3240S Fiber Optic Multiplexer
4.9.3 3240S Trap Configuration
Traps are special SNMP Messages that are sent to the Manager(s) when a specific event occurs. The managers are defined
in the access host table (refer to section 4.8.4, “SNMP & Access Host Table”). The 3240S will send traps to hosts whose
access level authorizes traps to be sent. These are access levels 3 (Read/Trap) and 4 (Read/Write/Trap).
The System Trap Configuration screen allows the operator to enable traps so that specific alarms show at the SNMP
management station(s). This also porvides a prevention method where the 3240S cannot generate traps that the operator
does not want sent.
• Master Enable/Disable Traps: This is the main switch to disable all traps or enable the traps that are enabled at a lower
level, such as Composite Sync Loss, Link Switch per port traps, etc., provided that Master Enable/Disable Traps has
Enable selected.
• Composite Sync Loss Trap: A trap will be sent to the manager(s) when the fiber optic receiver detects a sync loss
condition on the active link.
• Link Switch Trap: A trap will be sent to the manager(s) when the active link switches between the primary and
secondary or vice versa.
• Fault Relay State Trap: A trap will be sent to the manager(s) when the fault relay becomes activated.
• System Loopback Trap: A trap will be sent to the manager(s) whenever a system local or remote loopback is initiated.
• Configuration Error Trap: A trap will be sent to the manager(s) whenever a conflict is detected with the I/O cards. This
occurs when:
•
The type of I/O card is different between the local and remote Mux in reference to the same physical slot.
(e.g., a T1X - slot 1, unit 1 and an E1X - slot 1, unit 2).
• The logical address is different between the local and remote Mux for the same physical slot.
(e.g., a T1X card, slot 1, of unit 1 has its logical address set to 1 & 3; and a T1X card, slot 1 of unit 2 has its logical
address set to 2 & 4. Or a unit has two I/O cards in slot 1 and slot 3 with their logical addresses both set to 1 & 3,
or 2 & 4.)
• Card Insert/Remove Trap: A trap will be sent to the manager(s) whenever a manageable I/O card is inserted in or
removed from a 3240S chassis.
• Backup Link OK/Bad Trap: A trap will be sent to the manager(s) when the backup link goes from a bad (fiber bad) state
to a good state, or vice versa. The backup (or standby) link is the link that is not carrying the payload.
• Cold Start/Authentication Trap: A trap will be sent to the manager(s) upon a unit cold start. This is when the Mux is
powered up or when the SNMP Management Module goes through a reset. An authentication trap will be sent to the
manager(s) if the Mux receives an SNMP message with a wrong community string (refer to section 4.8.4.2 “Alias
Community String Table”). This could happen when an unauthorized SNMP management station is attempting to
access the unit with the wrong community strings.
• Power Supply Malfunction Traps: A trap will be sent to the manager(s) when an installed power supply fails in a system
equipped with dual power supplies.
