The following examples show some of the different types of messages that syslog reports.

Example—ARP Message

<62>00:00:51 192.168.3.169 [00]:ARP Update: MAC:080017014e00, IP:192.168.2.81

This message includes the following information:

•Priority=62, which means that the facility value is 7 (network new subsystem) and the severity value is 6 ( informational messages). You can derive this information from RFC-3164.

•The time offset is 00:00:51, which means that the most recent Cisco ATA reset was 51 seconds earlier.

•The IP address of the Cisco ATA is 192.168.3.169

•The tag value is 00, which corresponds to ARP messages. This is derived from Table 5-7 on page 5-42.

•The message itself begins with ARP Update and can be interpreted by means of RFC-3164.
