Troubleshooting Network Problems

The internal DRAC 4 Trace Log can be used by administrators to debug alerting or networking from the DRAC 4. The Trace Log can be accessed from the DRAC 4 Web-based interface by clicking the Diagnostics tab, and typing the gettracelog command. The Trace Log will appear and tracks the following information:

•DHCP — Traces packets sent to and received from a DHCP server.

•IP — Traces IP packets sent and received.

NOTE: In the DRAC 4 Trace Log, nonprintable ASCII characters are translated to printable ASCII characters. If the character code is less than 0x20, or between 0x7f and 0xa0 (inclusive), the value 0x40 is exclusive and the character before printing, after a "^" is added to the beginning. As a result, the ASCII carriage return character, 0xd, is printed as "^M" in the Trace Log.

NOTE: The DRAC 4 will not echo an ICMP (ping) with a packet size larger than 1500 bytes.

The Trace Log may also contain DRAC 4 firmware-specific error codes (relating to the internal DRAC 4 firmware, not the managed system’s operating system). Use Table 4-30 to help diagnose network problems reported by the internal DRAC 4 operating system.
