Linux DHCP

The Linux DHCP Server DSM for JSA accepts DHCP events using syslog.

JSA records all relevant events from a Linux DHCP Server. Before you configure JSA to integrate with a Linux DHCP Server, you must configure syslog within your Linux DHCP Server to forward syslog events to JSA.

For more information on configuring your Linux DHCP Server, consult the man pages or associated documentation for your DHCP daemon.

Syslog Log Source Parameters for Linux DHCP

If JSA does not automatically detect the log source, add a Linux DHCP log source on the JSA Console by using the Syslog protocol.

When using the syslog protocol, there are specific parameters that you must use.

The following table describes the parameters that require specific values to collect Syslog events from Linux DHCP:
