Switch 802.1x
xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch
Description
Enter a system name for the Switch, if so desired. This name will identify it in the Switch
network.
Enter the location of the Switch, if so desired.
Enter a contact name for the Switch, if so desired.
Displays the Dual Image support for the Switch, or the ability to store more than one
firmware code on the Switch without implementation.
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.
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.
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.
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 located in the IGMP Snooping folder contained in the L2 Features folder.
This field specifies that the Switch should only forward all multicast traffic to a multicast-
enabled router, if enabled. Otherwise, the Switch will forward all multicast traffic to any IP
router. The default is Disabled.
Use this pull-down menu to enable or disable GVRP on the Switch.
Telnet configuration is Enabled by default. If you do not want to allow configuration of the
system through Telnet choose Disabled.
The TCP port number. TCP ports are numbered between 1 and 65535. The "well-known"
TCP port for the Telnet protocol is 23.
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.
Simple Network Monitoring Protocol (SNMP) of the Switch is Enabled or Disabled here. The
Default is Disabled.
Remote monitoring (RMON) of the Switch is Enabled or Disabled here.
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, IP Source, IP Destination or IP Src & Dest (See the Link Aggregation section of
this manual).
MAC Address may enable by port or 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
section, under the Port Access Entity folder.
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 Authorization specifies that ports configured for 802.1x are initialized based on
the port number and the MAC address of the computer being authorized and are then
subject to any authorization parameters configured.
