DES-3028 DES-3028P DES-3028G DES-3052 DES-3052P Layer 2 Fast Ethernet Managed Switch The fields that can be configured are described below: Parameter Description System Name Enter a system name for the Switch, if so desired. This name will identify it in the Switch network. System Location Enter the location of the Switch, if so desired. System Contact Enter a contact name for the Switch, if so desired. Serial Port Auto Logout Time Select the logout time used for the console interface. This automatically logs the user out after an idle period of time, as defined. Choose from the following options: 2 Minutes, 5 Minutes, 10 Minutes, 15 Minutes or Never. The default setting is 10 minutes. Serial Port Baud Rate This field specifies the baud rate for the serial port on the Switch. there are four possible baud rates to choose from, 9600, 19200, 38400 and 115200. For a connection to the Switch using the CLI interface, the baud rate must be set to 9600, which is the default setting. MAC Address Aging Time This field specifies the length of time a learned MAC Address will remain in the forwarding table without being accessed (that is, how long a learned MAC Address is allowed to remain idle). To change this, type in a different value representing the MAC address age-out time in seconds. The MAC Address Aging Time can be set to any value between 10 and 1,000,000 seconds. The default setting is 300 seconds. IGMP Snooping To enable system-wide IGMP Snooping capability select Enabled. IGMP snooping is Disabled by default. Enabling IGMP snooping allows you to specify use of a multicast router only (see below). To configure IGMP Snooping for individual VLANs, use the IGMP Snooping window located in the IGMP Snooping folder contained in the L2 Features folder. Multicast Router Only This field specifies that the Switch should only forward all multicast traffic to a multicastenabled router, if enabled. Otherwise, the Switch will forward all multicast traffic to any IP router. The default is Disabled. MLD Snooping This field specifies the status of MLD Snooping on the Switch. MLD Snooping is used to discover ports on a VLAN that are requesting multicast data instead of flooding all ports on a selected VLAN with multicast traffic. The default is Disabled. Telnet Status Telnet configuration is Enabled by default. If you do not want to allow configuration of the system through Telnet choose Disabled. Telnet TCP Port Number (1-65535) The TCP port number. TCP ports are numbered between 1 and 65535. The "well-known" TCP port for the Telnet protocol is 23. Web Status Web-based management is Enabled by default. If you choose to disable this by selecting Disabled, you will lose the ability to configure the system through the web interface as soon as these settings are applied. Web TCP Port Number The TCP port number. TCP ports are numbered between 1 and 65535. The "well-known" TCP (1-65535) port for the Web is 80. RMON Status Remote monitoring (RMON) of the Switch is Enabled or Disabled here. Link Aggregation Algorithm The algorithm that the Switch uses to balance the load across the ports that make up the port trunk group is defined by this definition. Choose MAC Source, MAC Destination, MAC Src & Dest, (See the Link Aggregation section of this manual). Switch 802.1X MAC Address can be enabled by port or by the Switch's 802.1X function; the default is Disabled. This field must be enabled to view and configure certain windows for 802.1X. More information regarding 802.1X, its functions and implementation can be found later in this manual, under Monitoring > Port Access Control. Port-Based 802.1X specifies that ports configured for 802.1X are initialized based on the port number only and are subject to any authorization parameters configured. MAC-based 802.1X specifies Host-based authentication with which the ports configured for 802.1X are initialized based on the MAC address of the computer being authenticated. 27
