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 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). The default age-out time for the Switch is 300 seconds. 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 page under the IGMP folder.
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 select-
ing 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 currently being utilized by the Switch to connect to the web
interface. The "well-known" TCP port for the Web interface is 80.
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).
Remote monitoring (RMON) of the Switch is Enabled or Disabled here.
The Switch's 802.1x function may be enabled by port or by MAC Address; 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.
The user may use the pull down menu to choose between radius eap and radius pap for
the 802.1x authentication protocol on the Switch. The default setting is radius eap.
This field will enable or disable Asymmetric VLANs on the Switch. The default is
Disabled.
