SNMP traps and Syslog messages

Syslog messages
By default, the ADX device’s Syslog buffer is enabled and contains up to 50 entries. To display the
GSLB and other Syslog messages, enter the following command at any level of the CLI.
Syntax: show logging
In this example, the GSLB messages are shown in bold type. The GSLB messages in this example
all apply to the ADX devices at the Sunnyvale site. Three types of messages are shown:
• The first two GSLB messages are shown nearest the bottom, since new messages appear at
the top. These two messages indicate that the GSLB ADX device has established a GSLB
protocol connection to the site ADX devices (slb-1 at 10.157.22.209 and slb-2 at
10.157.22.210).
• The next two GSLB messages indicate that the Layer 4 health checks for TCP port 80 were
completed successfully. For sites with other applications, the ADX device sends separate Layer
4 TCP or UDP health checks for each of those applications.
• The final two GSLB messages in this example (the ones nearest the top of the log) indicate that
the site ADX devices responded to the Layer 3 health check (IP ping).
