SNMP traps
An SNMP trap is an informational message sent from an SNMP agent (in this case, the Router) to a manager.
When a manager receives a trap, it may log the trap as well as generate an alert message of its own.
Standard traps generated by Motorola Netopia® Embedded Software Version 8.7.4 include the following:
•An authentication failure trap is generated when the gateway detects an incorrect community string in a
received SNMP packet. Authentication Traps Enable must be On for this trap to be generated.
•A cold start trap is generated after the gateway is reset.
•An interface down trap (ifDown) is generated when one of the gateway’s interfaces, such as a por t, stops
functioning or is disabled.
•An interface up trap (ifUp) is generated when one of the gateway’s interfaces, such as a por t, begins
functioning.
Motorola Netopia® Embedded Software Version 8.7.4 sends traps using UDP (for IP networks).
You can specify which SNMP managers are sent the IP traps generated by the Motorola Netopia® Embedded
Software Version 8.7.4. Up to eight receivers can be set. You can also review and remove IP traps.
To go to the IP Trap Receivers screen, select IP Trap Receivers. The IP Trap Receivers screen appears.
