Displaying SIB Alarms
To display SIB alarms and error messages:
- Display Current SIB Alarms
- Display SIB Error Messages in the System Log File
- Display SIB Error Messages in the Chassis Daemon Log File
Display Current SIB Alarms
Purpose
To determine the details of the current SIB alarms.
Action
Table 1 lists the SIB alarms that display in the craft interface LCD display and at the command line. For conditions that trigger SIB alarms, see Display the Current Router Alarms.
Table 1: SIB Alarm Messages
Component | LCD Short Version | CLI Long Version |
|---|---|---|
SIB | SIB sib-number Failure | RED ALARM—SIB sib-number Fault |
SIB sib-number Removed | RED ALARM—SIB sib-number Absent | |
Spare SIB Failure | YELLOW ALARM—Spare SIB Fault | |
Spare SIB Removed | YELLOW ALARM—Spare SIB Absent | |
Check SIB | YELLOW ALARM—Check SIB |
To display the SIB environmental information, use the following command:
Sample Output
t640@host> show chassis alarms 1alarms currently active Alarm time Class Description 2004-01-29 18:37:09 PST Minor SIB 2 Not Online
Meaning
The command output displays the alarm date, time, severity level, and description
Display SIB Error Messages in the System Log File
Purpose
To determine the details of the SIB error messages in the system log file.
Action
To display the SIB error messages in the system log file, use the following command:
Sample Output
ser@host> show log messages | match sib SIB_STATE_OFFLINE_ACK_WAIT Jan 29 18:37:09 toto spmb0 CMGSIB: SIB #2 state transition SIB_STATE_OFFLINE_AC K_WAIT -> SIB_STATE_OFFLINE Jan 29 18:37:09 toto spmb0 CMGSIB: SIB #0 state transition SIB_STATE_SPARE -> S IB_STATE_ONLINE_WAIT
Meaning
The messages system log file records the time the failure or event occurred, the severity level, a code, and a message description. You can also use the show log messages | match sib command to see error messages that are generated when a SIB fails or is offline. Use this information to diagnose a SIB problem and to let the Juniper Networks Technical Assistance Center (JTAC) know what error messages were generated and the router events that occurred before and after the problem. For more information about system log messages, see the Junos OS System Log Messages Reference.
Display SIB Error Messages in the Chassis Daemon Log File
Purpose
To determine the details of the SIB error messages in the chassis daemon log file. The chassis daemon (chassisd) log file keeps track of the state of each chassis component.
Action
To display the SIB error messages logged in the chassis daemon log file, use the following command:
Sample Output
user@host> show log chassisd | match sib cli command Jan 29 18:37:07 CHASSISD_SNMP_TRAP10: SNMP trap: FRU power off: jnxFruContentsIn dex 15, jnxFruL1Index 3, jnxFruL2Index 0, jnxFruL3Index 0, jnxFruName SIB 2, jnx FruType 9, jnxFruSlot 3, jnxFruOfflineReason 7, jnxFruLastPowerOff 1701082, jnxF ruLastPowerOn 3250 Jan 29 18:37:09 send: yellow alarm set, device SIB 2, reason SIB 2 Not Online Jan 29 18:37:09 fm_recv_hsl_start_sib_ack plane case. Checking plane control to all line cards? Jan 29 18:37:09 fm_recv_hsl_start_sib_ack: Awaiting spmb ack for LC#0! Jan 29 18:37:09 fm_recv_hsl_start_sib_ack plane case. Checking plane control to all line cards? Jan 29 18:37:09 fm_recv_hsl_start_sib_ack: Awaiting spmb ack for LC#0! Jan 29 18:37:09 fm_recv_hsl_start_sib_ack plane case. Checking plane control to all line cards? Jan 29 18:37:09 fm_recv_hsl_start_sib_ack plane case. Sending plane control to a ll line cards!
Meaning
The chassisd database provides the date, time, and a component status message. The chassisd database is dynamic. It is initialized at router startup and is updated when components are added or removed. You can search for multiple items in the chassisd log file by using the | match sib command to see error messages that are generated when a SIB fails or is offline. Use this information to diagnose a SIB problem and to let JTAC know what error messages were generated and the router events that occurred before and after the problem. For more information about system log messages, see the Junos OS System Log Messages Reference.
