MAC Address
This field specifies the length of time a learned MAC Address will remain in the forwarding table
Aging Time
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 the user to specify use of a multicast router only
(see below). To configure IGMP Snooping for individual VLANs, use the IGMP Snooping
window under the IGMP Snooping folder.
IGMP Multicast
This field specifies that the Switch should only forward all multicast traffic to a multicast-enabled
Router Only
router, if enabled. Otherwise, the Switch will forward all multicast traffic to any IP router. The
default is Disabled.
To enable system-wide MLD Snooping capability, select Enabled. MLD snooping is Disabled by
MLD Snooping
default. Enabling MLD snooping allows you to specify use of a multicast router only (see below).
To configure MLD Snooping for individual VLANs, use the MLD Snooping window under the
MLD Snooping folder.
This field specifies that the Switch should only forward all multicast traffic to a multicast-enabled
MLD Multicast
Router Only
router, if enabled. Otherwise, the Switch will forward all multicast traffic to any IP router. The
default is Disabled.
GVRP Status
Use this drop-down menu to enable or disable GVRP on the Switch.
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
The TCP port number used for Telnet management of the Switch. The "well-known" TCP port for
Number (1-65535)
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
The TCP port number used for Web-based management of the Switch. The "well-known" TCP
Number (1-65535)
port for the Telnet protocol is 80.
SNMP is Disabled by default. The Switch supports the SNMP versions 1, 2c, and 3. Once
SNMP Status
SNMP is enabled, you can choose among three versions to monitor and control the Switch. The
three versions of SNMP vary in the level of security provided between the management station
and the network device.
RMON Status
Remote monitoring (RMON) of the Switch is Enabled or Disabled here.
Link Aggregation
The algorithm that the Switch uses to balance the load across the ports that make up the port
Algorithm
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).
Switch 802.1X
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.
Auth Protocol
The user may use the drop-down menu to choose between RADIUS EAP and Local for the
802.1X authentication protocol on the Switch. The default setting is RADIUS EAP.
