Continuous system monitor overview

• TM_ECC - Monitoring TM memory ECC errors.
• TM_CLOCK_SYNC - Monitoring clock synchronization among all TMs.
• TM_REG - Monitoring TM register bits, each of which indicates a problem in the TM.
• TM_Q_SCANNER - Monitoring TM queues.
• TCAM_SCAN - Scanning TCAM to discover corruptions.
• DRAM-CRC - Monitoring ingress DRAM CRC error, and isolate the ingress TM in case of severe
error condition.
• TX-BUFFER - Monitoring egress TM TX buffer stuck condition, this could result from ingress
DRAM CRC errors not isolated in time.
• PKT_PATH_SCAN - Sending and receiving packet to test path.
• FE_LINK - Monitoring FE serdes links.
• FE_FIFO - Monitoring congestion within FEs.
• FE_RW - Performing write/read tests to FEs.
• MP_DX - Monitoring the connectivity between backplane and management processor.
• LPM_ERR - Monitoring LP Longest Prefix Match memory (LPM) errors.
• MBridge FPGA - Monitoring management processor for FPGA failure.
Event Type
TM_LINK
TM link is the link between the line card and the switch fabric module. The event type TM_LINK
monitors this link for the errors reported on the link by the TM. Such as CRC, misalignment, code
group error, down links, and other. Here is an example from Syslog.
Dec 29 15:31:24:W:System: ALARM:LP15/TM3 has 6 links, less than the minimum to
maintain line rate
FE_LINK
FE link is the link between the line card and the switch fabric module. The event type FE_LINK
monitors this link for the errors reported on the link by the FE. Such as CRC, misalignment, code
group error, down links, and others. Here is an example from Syslog.
Dec 29 15:31:24:W:System: ALARM:LP15/TM3 has 6 links, less than the minimum to
maintain line rate
TM_CLOCK_SYNC
A packet is segmented into fixed size cells when sending into the FE from a TM. On the destination
TM, the received cells re-assembled into the packet. TM uses timestamps for disassembling and
assembling cells. To accomplish this, all TM clocks must be synchronized. This event type detects
TM clock out of sync errors. Here is an example from Syslog.
