Network Level
Messages concerning the network activity, for example about Ethernet and routing.
Services
Messages concerning services such as SNMP and SMTP.
Authentication
Messages concerning user authentication.
Device Ports
Messages concerning device ports and connections.
Diagnostics
Messages concerning system status and problems.
General
Any message not in the categories above.
Remote Servers
(#1 and #2)
The IPv4 or IPv6 address of the remote server(s) where system logs are stored.
The system log is always saved to local EMG storage. It is retained through EMG unit
reboots for files up to
Other Log Size
(see below). Saving the system log to a server
that supports remote logging services (see RFC 3164) allows the administrator to save
the complete system log history.
Note:
If the EMG is unable resolve the Remote Server hostnames or contact the
Remote Servers to send syslog messages, the syslog messages that cannot be sent to
a Remote Server may appear on the EMG console port.
RPM Log Size
The maximum size in Kbytes that RPM logs can grow to before they are pruned. When
the file is pruned, it will be pruned to 50% of the RPM Log Size.
Other Log Size
The maximum size in Kbytes that all logs other than the RPM logs can grow to before
they are pruned. When the file is pruned, it will be pruned to 50% of the Other Log Size.
Enable Log
Select to save a history of all configuration changes in a circular log. Disabled by
default. The audit log is saved through EMG reboots.
Size
The log has a default maximum size of 50 Kbytes (approximately 500 entries). You
can set the maximum size of the log from 1 to 500 Kbytes.
Include CLI
Commands
Select to cause the audit log to include the CLI commands that have been executed.
Disabled by default.
Include In System
Log
If enabled, the contents of the audit log are added to the system log (under the
General/Info category/level). Disabled by default.
Enable Logins
Enables or disables SSH logins to the EMG unit to allow users to access the CLI using
SSH. Enabled by default.
This setting does not control SSH access to individual device ports. (See
Device Ports
- Settings (on page 191)
for information on enabling SSH access to individual ports.)
Most system administrators enable SSH logins, which is the preferred method of
accessing the system.
Web SSH
Enables or disables the ability to access the EMG command Iine interface or device
ports (connect direct) through the Web SSH window. Disabled by default.
Timeout
If you enable SSH logins, you can cause an idle connection to disconnect after a
specified number of minutes. Select
Yes
and enter a value of from 1 to 30 minutes.
Timeout Data

If idle connection timeouts are enabled, this setting indicates the direction of data used
to determine if the connection has timed out. Select the type of data direction:
