This article explains the CHASSISD_IFDEV_DETACH_PIC syslog message.
The problem related to this syslog message is described in the following sections:
The CHASSISD_IFDEV_DETACH_PIC message is reported in the system message file when the PIC is shut down. If the Flexible PIC Concentrator (FPC) is shut down, several of these types of messages are reported in the file, as each PIC in that FPC is also shut down. Depending on the logging level, you may see the following messages:
CHASSISD_FRU_EVENT: scb_recv_slot_detach: detached FPC 0 CHASSISD_IFDEV_DETACH_FPC: ifdev_detach(0) CHASSISD_IFDEV_DETACH_PIC: ifdev_detach_pic(0/0) CHASSISD_IFDEV_DETACH_PIC: ifdev_detach_pic(0/2)
The CHASSISD_IFDEV_DETACH_PIC message is a notification level message. It could be caused by a normal shut down of the PIC, hardware failure, or loss of power to the router.
These messages appear in the logs depending on the logging level. The severity level of this message is info. Therefore, if you have syslog set to log informational messages, these messages will appear in the log. Check the events proceeding this log message to determine if this message is the result of an expected event, such as restarting the system or restarting the PIC.
Check the following logs for information:
request support information | no more show log messages | no more show log chassisd | no more request pfe execute command "show nvram" target FPCx (x is the FPC slot indicated) request pfe execute command "show syslog messages" target FPCx (x is the FPC slot indicated)
Note which event occurred prior to the CHASSISD_IFDEV_DETACH_FPC message. Also, check if there are any current alarms in the show chassis alarms output.
Below is an example of the CHASSISD_IFDEV_DETACH_PIC message after a hardware error:
rsd-master fpc2 CMG: Bouncing pic 3 due to errors. chassisd[1523]: CHASSISD_IFDEV_DETACH_PIC: ifdev_detach_pic(2/3)
The chassis process (chassisd) detached the interface devices for the indicated Physical Interface Card (PIC).
These messages, by themselves, are harmless. The cause of the notification is an event preceding the messages. Depending on the event, there may be a reason to troubleshoot further or just ignore the message as expected behavior. If the CHASSISD_IFDEV_DETACH_PIC message is not caused by a system power-down or a restart of the PIC or FPC, open a case with your technical support representative to further investigate why the message is appearing. Note: If you change the logging level under syslog, these messages will not appear.
