xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch
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.
MLD Snooping To enable system-wide MLD Snooping capability select Enabled. MLD snooping is Disabled by
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.
MLD 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.
GVRP Status Use this pull-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.
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.
The user may use the pull-down menu to choose between RADIUS EAP and Local for the
Auth Protocol
802.1X authentication protocol on the Switch. The default setting is RADIUS EAP.
HOL Prevention If this option is enabled it prevents the forwarding of data to a port that is blocked. Traffic that
would normally be sent to the buffer memory of the Switch's TX queue is dropped so that
memory usage is conserved and performance across all ports remains high.
Jumbo Frame This field will enable or disable the Jumbo Frame function on the Switch. The default is
Disabled. Max. Jumbo frame size = 9216 bytes if this is enabled.
Syslog State The user may globally enable or disable the Syslog function here by using the pull-down menu.
The default is Disabled.
ARP Aging time The user may set the ARP Aging Time here by entering a time between 0 and 65535 minutes.
The default setting is 20 minutes.
