General

Any message not in the categories above.

Remote Servers (#1 and #2)

IP address of the remote server(s) where system logs are stored.

The system log is always saved to local SLC storage. It is retained through SLC reboots for files up to 200K. 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.

SSH

Enable Logins

Enables or disables SSH logins to the SLC to allow users to access the CLI using SSH. Enabled by default.

This setting does not control SSH access to individual device ports. (Device Ports – Settings provides 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 SLC command line interface or device ports (connect direct) through a 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.

Note: You must reboot the unit before a change will take effect.

SSH Port

Allows you to change the SSH login port to a different value in the range of 1 - 65535. The default is 22.

Note: You must reboot the unit before a change will take effect.

SSH V1 Logins

Enables or disables SSH version 1 incoming connections to the SLC. Enabled by default.

Note: Disabling SSH V1 blocks Web SSH CLI and Web SSH to device port connections on the SLC Network page. Also, you must reboot the SLC before a change will take effect.

Telnet

Enable Logins

Enables or disables Telnet logins to the SLC to allow users to access the CLI using Telnet. Disabled by default.

This setting does not control Telnet access to individual device ports. (Device Ports – Settings provides information on enabling Telnet access to individual ports.)

You may want to keep this option disabled for security reasons.

Web Telnet

Enables or disables the ability to access the SLC command line interface or device ports (connect direct) through a web Telnet window. Disabled by default.

Timeout

If you enable Telnet 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.

Note: You must reboot the unit before a change will take effect.

Audit Log

Enable Log

Select to save a history of all configuration changes in a circular log. Disabled by default. The audit log is saved through SLC 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.

SMTP

Server

IP address of your network’s Simple Mail Transfer Protocol (SMTP) relay server.

Phone Home

If enabled, the SLC will attempt to phone home every hour until it has contacted an SLM and provided it with its configuration.

IP Address

IP address of the SLM.
