About the Device
The Dynamic Host Configuration Protocol (DHCP) is a network protocol used to assign IP addresses and provide configuration information to devices such as servers, desktops, or mobile devices, so they can communicate on a network using the Internet Protocol (IP). ISC DHCP is a collection of software that implements all aspects of the DHCP (Dynamic Host Configuration Protocol) suite. ISC DHCP solution supports both IPv4 and IPv6, and is suitable for use in high-volume and high-reliability applications.

Device Configuration
To direct DHCP logs to a remote server:
To check the DHCP logging facility, follow the steps below.
Open the dhcpd.conf file (located in the /etc/dhcp directory).
Look for the log-facility statement in the file. It will look like: log-facility local6;
Note down the facility (the string afterlog-facility, for example, local6 in the above case) and close the file.
To edit the rsyslog.conf file:
Open the /etc/rsyslog file (or /etc/syslog file in older Linux and Solaris distributions).
For ISC DHCP installed on a Linux machine:
Add the following lines at the end of the “### RULES ######” section:
<logfacility>.*@@<CyberHub_IP_Address>:<601>where logfaciltiy => facility noted in step 1(c) from the above section
Save and close the file.
Restart the rsyslog service by executing following command:
service rsyslog restart
For ISC DHCP installed on Solaris machine:
Add the following lines at the end of the file:
<logfacility>.info @@<CyberHub_IP_Address>:<601><logfacility>.err @@<CyberHub_IP_Address>:<601> where Logfaciltiy => facility noted in the step 1(c) from the above section.
Save and close the file.
Restart rsyslog service by executing following command:
svcadm restart system-log
