Supported SNMP Traps
A trap is an unsolicited message that is sent from the T1 access unit to the SNMP
trap manager when the T1 access unit detects certain prespecified conditions.
These traps enable the SNMP manager to gauge the state of the network.
The T1 access unit supports the following traps:
H warm-start
H authentication-failure
H enterprise-specific (those specific to T1 access unit)
H link-up
H link-down
Refer to Appendix D,
SNMP Cross-Reference
, for more information on traps.
Dialing Out and Sending SNMP Traps
You can control whether generated SNMP trap messages will initiate a call if a
connection on the COM port external device has not already been established.
Use the Alarms Options screen to enable the T1 access unit’s automatic call
initiation (dial out) on the COM port external device to send an SNMP trap
message.
