The message-source Field on a T640 Routing Node in a Routing Matrix


The format of the message-source field in a message on a T640 routing node in a routing matrix depends on two factors:

  • Whether the message was generated on the local Routing Engine or the other Routing Engine. Messages from the other Routing Engine appear only if its configuration includes the other-routing-engine statement at the [edit system syslog host] hierarchy level.

  • Whether the message was generated by a kernel or user-space process, or by the microkernel on a hardware component.

Table 1 specifies the format of the message-source field in the various cases.

hostname-lccY process[processID]


hostname-lccY lccY-componentZ process



hostname-lccY lccY-reX process[processID]


hostname-lccY lccY-reX lccY-componentZ process

hostname-lccY is the hostname of the local Routing Engine and the T640 routing node’s LCC index number.

lccY-componentZ process identifies the hardware component and process that generated the message (Y matches the value in the hostname-lccY field and the range of values for Z depends on the component type). For example, lcc0-fpc0 CMLC refers to a process on the FPC in slot 0. The T640 routing node has index LCC0 in the routing matrix.

lccY-reX indicates that the other Routing Engine on the routing node generated the message (Y matches the value in the hostname-lccY field and X is 0 or 1).

process[process-ID] is the name and PID of the kernel or user-space process that generated the message. If the lccY-reX field also appears, the process is running on the other Routing Engine. If a process does not report its PID, the [process-ID] part does not appear.
