The three CPUs use Fast Ethernet connections to communicate to each other and to the line card CPUs using Inter-Processor Communication (IPC). The CP monitors the health status of the other processors using heartbeat messaging exchange. Message 6 CP monitor %RPM1-P:CP %IPC-2-STATUS: target rp2 not responding %RPM0-S:CP %RAM-6-FAILOVER_REQ: RPM failover request from active peer: Auto failover on failure %RPM0-S:CP %RAM-6-ELECTION_ROLE: RPM0 is transitioning to Primary RPM. %RPM0-P:CP %TSM-6-SFM_SWITCHFAB_STATE: Switch Fabric: UP FTOS automatically saves critical information about the IPC failure to NVRAM. Such information includes: • Status counters on the internal Ethernet interface • Traffic profile of the inter-CPU bus • Kernel drops • High CPU exception conditions Upon the next boot, this information is uploaded to a file in the CRASH_LOG directory. Use the following command sequence beginning in EXEC mode to capture this file for analysis by the Dell Force10 TAC. Step Task Command Mode 1 Display the directories in flash memory. The output dir flash: should include: 1 drwx 2048 Jan 01 1980 00:00:06 CRASH_LOG_DIR EXEC 2 Change to the CRASH_LOG directory. cd CRASH_LOG_DIR EXEC 3 View any saved files in the CRASH_LOG dir directory.
