Configuring syslog Servers

Configuring syslog Servers
Information generated by the run time event logging filters can be transmitted to a syslog server for permanent
storage.
Important
Important
Use the following example to configure syslog servers:
configure
context local
Notes:
• ip_address specifies the IP address of a system log server on the network in IPv4 dotted-decimal or IPv6
• A number of keyword options/variables are available for the logging syslog command. Refer to the
• Repeat as needed to configure additional syslog servers. There is no limit to the number of syslog servers
Save the configuration as described in the Verifying and Saving Your Configuration chapter.

Configuring Active Logs

Active logs are event logs that are operator configurable on a CLI instance-by-CLI instance basis. Active logs
configured by an administrative user in one CLI instance are not displayed to an administrative user in a
different CLI instance. Each active log can be configured with filter and display properties that are independent
of those configured globally for the system. Active logs are displayed in real time as they are generated.
Active logs are not written to the active memory buffer by default. To write active logs to the active memory
buffer execute the following command in the Global Configuration mode:
[local]
When active logs are written to the active memory buffer, they are available to all users in all CLI instances.
Use the following example to configure active logging in Global Configuration mode:
[local]

The data transmitted to the syslog server is meant to be used for informational purposes. Functions such
as billing and performance monitoring should not be based on syslogs.
Although the system provides the flexibility to configure syslog servers on a context-by-context basis, it
is recommended that all servers be configured in the local context in order to isolate the log traffic from
the network traffic.
