ds1LinkFrameSlipTrap
Module: RAD-MIB
OID (symbolic): RAD-MIB::ds1LinkFrameSlipTrap
OID (numeric): 1.3.6.1.4.1.164.3.1.6.4.0.3
Node type: NOTIFICATION-TYPE
Description:
This trap indicates that a Frame Slip occurred at the user DS1 interface. This usually indicates timing problems (incorrect selection of timing reference), on the user DS1 link.
What is ds1LinkFrameSlipTrap?
This notification (trap) is generated when a frame slip is detected on a DS1 (T1/E1) link, indicating that synchronization has been momentarily lost between the transmitting and receiving sides of the digital circuit. Frame slips typically signal timing issues such as incorrect timing reference selection or unstable clock signals, which can cause data corruption or loss; operators receiving this trap should investigate and correct the underlying timing problem. This alert is critical for maintaining the integrity of synchronous digital services that depend on precise timing alignment.
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> '' RAD-MIB::ds1LinkFrameSlipTrap snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.164.3.1.6.4.0.3
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
