dsx3LineStatusChange
Module: DS3-MIB
OID (symbolic): DS3-MIB::dsx3LineStatusChange
OID (numeric): 1.3.6.1.2.1.10.30.15.0.1
Node type: NOTIFICATION-TYPE
Description:
A dsx3LineStatusChange trap is sent when the value of an instance of dsx3LineStatus changes. It can be utilized by an NMS to trigger polls. When the line status change results in a lower level line status change (i.e., ds1), then no traps for the lower level are sent.
What is dsx3LineStatusChange?
This SNMP trap notification is sent whenever the operational status of a DS3 (T3) line changes, such as transitions from up to down or vice versa. The trap can be used by a Network Management System to trigger immediate polls rather than waiting for scheduled polling intervals, enabling faster detection of circuit failures. When a line status change causes lower-layer (DS1/T1) impacts, separate traps are not generated to avoid redundant notifications.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' DS3-MIB::dsx3LineStatusChange snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.10.30.15.0.1
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
