Troubleshooting Network Problems
The internal DRAC 5 Trace Log is used by administrators to debug DRAC 5
alerting and networking. You can access the Trace Log from the DRAC 5
Web-based interface by clicking the Diagnostics tab, typing the gettracelog
command, or typing the racadm gettracelog command. See "gettracelog" on
page 275 for more information.
The Trace Log tracks the following information:
• DHCP — Traces packets sent to and received from a DHCP server.
• IP — Traces IP packets sent and received.
The trace log may also contain DRAC 5 firmware-specific error codes that are
related to the internal DRAC 5 firmware, not the managed system’s operating
system.
NOTE: The DRAC 5 will not echo an ICMP (ping) with a packet size larger than
1500 bytes.
netstat Prints the content of the routing table. If the optional
interface number is provided in the text field to the right of
the netstat option, then netstat prints additional information
regarding the traffic across the interface, buffer usage, and
other network interface information.
ping <IP
Address>
Verifies that the destination IP address is reachable from the
DRAC 5 with the current routing-table contents. A
destination IP address must be entered in the field to the right
of this option. An Internet control message protocol (ICMP)
echo packet is sent to the destination IP address based on the
current routing-table contents.
gettracelog Displays the DRAC 5 trace log. See "gettracelog" on page 275
for more information.
