Displaying log information
To display the syslog messages in the device’s local log file, enter the following command.
Syntax: show logging
Here is an example of a log that contains SNMP authentication traps. In this example, someone
attempted to access the Brocade Virtual ADX three times using invalid SNMP community strings.
The unsuccessful attempts indicate either an authorized user who is also a poor typist, or an
unauthorized user who is attempting to access the device.
This example shows a log entry for an IP address conflict between the Brocade Virtual ADX and
another device on the network.
In addition to placing an entry in the log, the software sends a log message to the Syslog server, if
you have configured one, and sends a message to each open CLI session.
