Installing and Configuring DHCPv6 2

Troubleshooting
The syslog.log File
Chapter 4 49
The syslog.log File
The syslog.log file contains the log messages for all subsystems. You
can use the information contained in this file to characterize a problem.
Both the DHCPv6 2.001 client and server daemons log all the error
messages in the /var/adm/syslog/syslog.log file. You can use this file
to identify and rectify errors. The client and the server check for the
validity of server requests and client requests, respectively.
Error Messages
The dhcpv6d daemon validates the configuration file and logs the error
messages into the syslog file.
Table 4-1 describes the error messages that dhcpv6d logs in the syslog
file and also the cause and method to rectify the problem.

No Address Pool Name When you do not specify
the address pool name

Specify the address pool name in
the DHCP_ADDRESS_POOL section
and restart the dhcpv6d server.
process_msg: not a
valid option <20> in
<9> message
When the DHCPv6 2.001
client sends a message
with an option that is not
supposed to be part of
that message.
This error message is
logged when the
OPTION_RECONF_ACCEPT(

DECLINE(9) message.
You must configure your client in
conformance to RFC 3315
(Dynamic Host Configuration
Protocol for IPv6 (DHCPv6)).
