Configure the amount of data sent to the logs
Enable or disable SSH and Telnet logins
Enable a Simple Network Management Protocol (SNMP) agent
Note: The SLC supports both MIB-II (as defined by RFC 1213) and a private enterprise MIB. The SLC product CD includes the MIB definition files for the private enterprise MIB. The private enterprise MIB provides read-only access to all statistics and configurable items provided by the SLC. It provides read-write access to a select set of functions for controlling device ports (zeroing device port counters, clearing the local log, and terminating all connections associated with a device port). See the MIB definition file for details.

Complete or view the following sections:
Alert Levels |
Select one of the following alert levels from the drop-down list for each message category:
|
Network |
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) |
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. |
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. |
Server |
IP address of your network’s Simple Mail Transfer Protocol (SMTP) relay server. |
Enable |
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. |
Last Attempt (display only) |
Date and time of last connection attempt. |
Results (display only) |
Indicates whether the attempt was successful. |
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. (See Device Ports – Settings 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 SLC command Iine interface using Web SSH. 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. |
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. (See Device Ports – Settings for 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 Iine interface using Web Telnet. 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. |
Enable Agent |
Enables or disables Simple Network Management Protocol (SNMP) agent, which allows read-only access to the system. Disabled by default. |
Enable Traps |
Traps are notifications of certain critical events. Disabled by default. This feature is applicable when SNMP is enabled. Examples of traps that the SLC sends include:
The SLC sends the traps to the host identified in the NMS field. |
NMS |
When SNMP is enabled, an NMS (Network Management System) acts as a central server, requesting and receiving SNMP-type information from any computer using SNMP. The NMS can request information from the SLC and receive traps from the SLC. Enter the IP address of the NMS server. Required if you selected Enable Traps. |
RO (Read-Only) Community |
A string that acts like a password for an SNMP manager to access the read-only data the SLC SNMP agent provides. The default is public. |
RW (Read-Write) Community |
A string that acts like a password for an SNMP manager to access the read-only data the SLC SNMP agent provides and to modify data where permitted. The default is private. |
Trap Community |
The trap used for outgoing generic and enterprise traps. Traps sent with the Event trigger mechanism still use the trap community specified with the Event action. The default is public. |
Location |
Physical location of the SLC (optional). Useful for managing the SLC using SNMP. Up to 20 characters. |
Contact |
Description of the person responsible for maintaining the SLC, for example, a name (optional). Up to 20 characters. |
V3 User |
SNMP v3 is secure and requires user-based authorization to access SLC MIB objects. Enter a user ID. The default is snmpuser. Up to 20 characters. |
V3 Password and Retype Password |
Password for accessing the SNMP v3. The default is SNMPPASS. Up to 20 characters. |
Alarm Delay |
Number of seconds delay between outgoing SNMP traps. |
