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 Tabl e 4-30 to help
diagnose network problems reported by the internal DRAC 4 operating system.
