Memory Logs on the 200/300 Series Managed Switches

Objectives

The 200/300 Series Managed Switches have the ability to record a set of messages, called logs, which gives information about system events. The switch stores two sets of local logs: one list of logged events written to RAM, which is erased after reboot, and a cyclical log-file written to Flash memory, which is saved upon reboot. In addition, these logs can be sent to a remote SYSLOG server where they can easily be viewed and monitored in the form of traps and SYSLOG messages.

This article explain how to view system logs and how to configure logs on the 200/300 Series Managed Switches.

Applicable Devices

• SF/SG 200 and SF/SG 300 Series.

Software Version

• 1.3.0.62

RAM Memory Logs

This section explains how to access the RAM Memory Log Table, and its different options.

Step 1. Log in to the web configuration utility and choose Status and Statistics > View Log > RAM Memory. The RAM Memory page opens:

The RAM Log Table has these fields:

• Log Index — Log entry number.

• Log Time — Date and time the log was created.

• Severity — Event Severity.

• Description — Informational message describing the event logged.

Step 2. (Optional) To disable the alert blink function, click Disable Alert Icon Blinking.

Step 3. (Optional) To see a specific number of entries in the RAM Memory Log Table, in the Showing drop-down list, choose the number of entries you want to see per page.

Step 4. (Optional) To see the next page of entries in the RAM Memory Log Table, click the Next button.

Step 5. (Optional) To Clear the logs in RAM, click Clear Logs.

Flash Memory Logs

This section explains how to access the Flash Memory Log Table, and its different options.

Step 1. Log in to the web configuration utility and choose Status and Statistics > View Log > Flash Memory. The Flash Memory page opens:

The Flash Memory Log Table has these fields:

• Log Index — Log entry number.

• Log Time — Date and time the log was created.

• Severity — Event Severity.

• Description — Informational message describing the event logged.

Step 2. (Optional) To see a specific number of entries in the Flash Memory Log Table, in the Showing drop-down list, choose the number of entries you want to see per page.

Step 3. (Optional) To see the next page of entries in the Flash Memory Log Table, click the Next button.

Step 4. (Optional) To Clear the logs in RAM, click Clear Logs.

Logs Setup

This section explains how to configure the different Logs options the 200/300 Series Managed Switches offers.

Step 1. Log in to the web configuration utility and choose Administration > System Log > Log Settings. The Log Settings page opens:

Step 2. In the Logging field, check the Enable check box to enable logs.

Step 3. (Optional) To Enable Syslog Aggregator, in the Syslog Aggregator field, check the Enable check box. This feature enables identical and sequential logs to display as a single message. The number of times a message has been aggregated is included in the message information.

Step 4. If Syslog Aggregator is enabled, in the Max Aggregator Time field, enter the time interval in seconds that syslogs messages are aggregated.

Step 5. Under RAM Memory Logging and Flash Memory Logging, check the events check boxes you want the switch to keep a log. The following are the events you can check:

• Emergency — System is not usable.

• Alert —  An Action is needed. This event tells the user to perform a specific action on the device immediately

• Critical — The System is in a critical condition. This event has more relevance than an error event and needs to be checked, otherwise, the switch could not function at all.

• Error — The System is in error condition. The switch works under an error, and tells the user where the error was originated.

• Warning — A System warning has occurred. a system change, whether hardware or software, occurred and some of the switch components might not be working properly.

• Notice — The System is functioning properly, but a system notice has occurred.

• Informational — This event only show information about the activities in the device.

• Debug — Shows Detailed information about an event. This event will constantly keep information about everything the switch performance.

Remote Log Servers

This section explains how to add a remote log server to the 200/300 Series Managed Switches.

Step 1. Log in to the web configuration utility and choose Administration > System Log > Remote Log Servers. The Remote Log Servers page opens:

The Remote Log Server Table shows all Syslog servers currently configured and includes these fields:

• Log Server — The IP Address or domain name of the Syslog server.

• UDP Port — The Syslog server UDP port to where the logs are sent.

• Facility — The value that identifies the device from which the logs are originated.

• Description — A description of the Syslog server.

• Minimum Severity — The minimum severity level required for logs to be sent to the server.

Step 2. Click Add to add a log server. The Add Remote Log Server window appears.

Step 3. In the Server Definition field, click By IP Address to enter the IP address of the server, or click By Name to enter the name of the server.

Step 4. In the IP Version field, click Version 6 or Version 4 to enter the server IP address.

Step 5. If version 6 is chosen, in the IPv6 Address Type field, click Link Local Or Global. A link local IPv6 address uniquely identifies host on a single network link, while a global IPv6 address is visible and reachable from other networks.

Step 6. If the IPv6 Address Type chosen is Link Local, choose the appropriate link local interface in the Link Local Interface drop-down list.

Step 7. In the Log Server IP Address/Name field, enter the IP address of the remote log server.

Step 8. In the UDP Port field, enter the UDP port to which the logs will be sent to the remote server.

Step 9. In the Facility drop-down list, choose the facility value from which system logs are sent to the remote server.

Step 10. (Optional) To enter a description about the remote log server, in the Description field, enter the desired description.

Step 11. In the Minimum Severity drop-down list, choose the minimum level of system log messages that are going to be sent to the remote server..

Step 12. Click Apply to save your configuration.

Note: To edit or delete a remote log server, refer to the section Edit a Remote Log Server.

Edit a Remote Log Server

This section explains how to edit a remote log server.

Step 1. Log in to the web configuration utility and choose Administration > System Log > Remote Log Servers. The Remote Log Servers page opens:

Step 2. To edit a remote log server configuration, check the check box of the remote server you wish to edit.

Step 3. Click Edit. The Edit Remote Log Server window appears.

Step 4. In the Log Server IP Address drop-down list, choose an available IP address.

Step 5. In the UDP Port field, change the UDP port number to the desired value.

Step 6. In the Facility drop-down list, change the facility value to the desired value.
