System Summary Information

Step 1. Log in to the web configuration utility and choose Status and Statistics > System Summary. The System Summary page opens:

The following information is displayed in the System Information area:

• System Operation Mode - Displays the operation mode of the switch. There are two operation modes available; Layer 2 and Layer 3 (of the TCP/IP model). With Layer 2 operation mode, the switch acts entirely as a layer 2 switch. With Layer 3 operation mode, the switch acts as a layer 2 switch but also performs layer 3 tasks.

• System Description - A description of the system.

• System Location - The physical location of the switch. To change the information, click Edit.

• System Contact - The name of a contact person.  To change the information, click Edit

• Host Name - The name of the switch. By default, the switch Host Name is composed of the word switch, with the three least significant bytes of the switch MAC address.  To change the information, click Edit.

• System Object ID - The unique SNMP object ID for this product.

• System Uptime - Time elapsed since the last reboot.

• Current Time - The current system time.

• Base MAC Address - Switch MAC address.

• Jumbo Frames - Jumbo frame support status. This support can be enabled or disabled on the Port Settings page. Jumbo frame support takes effect only after it is enabled and the switch is rebooted. Jumbo Frames are Ethernet frames with a size of 1500 bytes or more.

Information about the available services on the switch is located in the TCP/UDP Services Status area:

Note: If you wish to alter the status of TCP/UDP services, click Edit. 

• HTTP Service - Displays the current status (Enable or Disable) of the HTTP service.

• HTTPS Service - Displays the current status (Enable or Disable) of the HTTPS service. HTTPS is a secure version of HTTP.

• SNMP Service - Displays the current status (Enable or Disable) of the SNMP (Simple Network Management Protocol) service. SNMP offers you the tools to manage and control a network environment.

• Telnet Service - Displays the current status (Enable or Disable) of the Telnet service. Telnet is a protocol that allows you to establish a remote connection with a network.

• SSH Service - Displays the current status (Enable or Disable) of the SSH (Secure Shell) service. SSH also allows you to establish a remote connection with a network, but is more secure than Telnet.

The following information is displayed in the Software Information area:

• Firmware Version (Active Image) - Firmware version number of the software image that is currently in use.

• Firmware MD5 Checksum (Active Image) - MD5 checksum of the active image. MD5 is a hash algorithm that encrypts data. In this case, the firmware produces a MD5 checksum value, with the purpose of data integrity and protection of the firmware data.

• Firmware Version (Non-active) - Firmware version number inactive software image.

• Firmware MD5 Checksum (Non-active) - MD5 checksum of the inactive software image. Since the ESW2 Series Managed Switches can have up to two different firmware, each firmware has their own MD5 checksum value for data integrity.

• Boot Version - Boot image version number.

• Boot MD5 Checksum - MD5 checksum of the boot image.

• Locale - Locale of the first language.

• Language Version - Firmware version of the primary language of the active image.

• Language MD5 Checksum - MD5 checksum of the language file.

• Serial Number - Displays the serial number of the switch.

• PID VID - Displays the part number and the version ID of the switch.
