Address VLNC64 circuit pack SNMP traps

Procedure 5-7: Address VLNC64 circuit pack SNMP traps

Overview

Use this procedure to address VLNC64-related SNMP traps.

If the Alcatel-Lucent 1850 TSS-5 shelf is equipped with a VLNC64 Circuit Emulation Mini-Hub circuit pack, service-affecting incoming signal failures and equipment failures are reported using circuit pack faceplate LED indicators and Simple Network Management Protocol (SNMP) traps.

To address VLNC64 circuit pack related failures, refer to Procedure 5-3: Address VLNC40/42/42B, VLNC60/61/62, or VLNC64 circuit pack related failures.

timingSwitchover	The timing source for the system changed	If timing source changed from lower quality to higher quality source, then no action is required. If preceded by an administrative action such as a system reset or reconfiguration of timing source, then no action is required. If external timing (BITS) is used, ensure that the port receives good signal. If 1588 timing is used, Ensure that the 1588 protocol has valid timing source using the command `show ptp-1588`. Ensure that the 1588 Master system has valid timing source. Ensure that there is network connectivity between this system and 1588 Master system. On the 1588 Master, swap the primary and backup ports for 1588 transmission and reception.
1588 MIB
ptp1588Notifications	On 1588 Slave system, Master clock quality, accuracy changed or Master system changed. On Master 1588 system, clock quality, accuracy changed.	On the 1588 Slave system, if the trap is for change in clock quality or accuracy of the Master, then no action is required. On the 1588 Slave system, if the trap is for change of Master node, then ensure that the Master node has no problems in 1588 using. Use the command `show ptp-1588` for the purpose. On the 1588 Master system, if the trap is for change in clock quality or accuracy, then ensure that the system timing source of 1588 is a good signal.
ptp1588MasterOper ationalModeChange	The trap reports the value of ptp1588OperationalMode as part of the notification message.	If the reported value is master(1) or slave(2), ensure that it is the intended operational mode of the system. If the reported value is passive(3), the system has detected another 1588 master in the network. Ensure that this is the intended behavior of the system. If not, take corrective action to remove the other master in the network.
T1/E1 Alarms MIB
Traps for declaring T1/E1 AIS, RAI, OOL	These traps indicate that the corresponding alarm is declared on the port due to loss of signal or faulty signal or specific pattern in the signal.	1. If the encapsulation on the port is SAToP, ensure that the associated T1/E1 PWEs are operationally up and do not have any alarms. 2. Follow generic procedures for resolving incoming T1/E1 alarms.
Traps for declaring T1/E1 EOOF		1. Ensure that the configuration for signalformat matches at both ends of the T1/E1 port. 2. Ensure that the signal sent from the other endpoint matches the configured signalformat. 3. Follow generic procedures for resolving incoming T1/E1 alarms.

BufferUnderRun	PWE detected Buffer UnderRun condition	1. If this is not reported frequently, then no action is required. 2. Increase the configured initial delay value of the PWE using `initial-delay`.
BufferOverRun	PWE detected Buffer Overrun condition.	1. If this is not reported frequently, then no action is required. 2. Increase the configured jitter buffer value of the PWE using `jitter-buffer-size`.
L-bit	PWE set/cleared L-bit condition.	If the trap is for clear condition, then no action is required. If the trap is for set condition, then the system at the remote endpoint of this PWE has an alarm on the associated T1/E1 interface. Follow generic procedures for resolving T1/E1 alarms.
Loss Of Packets	PWE set/cleared Loss of Packets condition.	1. If the trap is for clear condition, then no action is required. 2. Ensure that the corresponding incoming PSN Tunnel is operationally up on the system. The CLI command show psntunnel all, provides this information. 3. Ensure that the system at the remote endpoint of this PWE transmits CESoETH frames. If the remote endpoint is an 1850 TSS-5, the CLI command `show pwe perfmon`, provides this information. 4. Ensure that the PSN network between the 2 endpoints of the PWE have proper connectivity. This can be done by monitoring port statistics at various interfaces along the path of the PWE. For the 1850 TSS-5, the port statistics can be monitored via CLI command `show interface ethernet`. 5. Contact next level of support.
R-bit	PWE set/cleared R-bit condition.	1. If the trap is for clear condition, then no action is required 2. If the trap is for set condition, then the system at the remote endpoint of the PWE is in Loss of Packets condition. Follow the resolution procedure for Loss of Packets for the system on the remote endpoint of the PWE. If the remote system is a 1850 TSS-5 the procedures are specified under resolution for Loss of Packets Trap. 3. Contact next level of support.
PWESwitchoverNotification	The PWE switched over to another PSN Tunnel.	1. If preceded by an Administrative action such as disabling the Ethernet port or PSN Tunnel, then no action is required. 2. If this trap is received with the psnTunnelDown trap, where the Tunnel was the previously active path for the PWE, then no action is required. 3. If this trap is received with an psnTunnelUp, then no action is required. The PWE looks for better path periodically. If the configured active Tunnel is available, then it switches to it.
