Algorithm
Switch 802.1X
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.
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 window
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.
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 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.
The TCP port number. TCP ports are numbered between 1 and 65535. The "well-known" TCP
port for the Web is 80.
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, (See the Link Aggregation section of this manual).
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.
