xStack DGS-3400 Series Fast Ethernet Switch
Device Information menu configurable parameters include those described in the table below.
Parameter Description
Serial Port Auto
Logout Time 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 .
Serial Baud Rate This field specifies the baud rate for the serial port on the Switch. This fields menu is set at
115200 and cannot be changed.
MAC Address
Aging Time 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.
IGMP Snooping 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
under the IGMP folder.
Multicast Router
Only 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 .
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
Number (1-65535) The TCP port number used for Telnet management of the Switch. The "well-known" TCP port
for 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
Number (1-65535) The TCP port number used for Web-based management of the Switch. The "well-known" TCP
port for the Telnet protocol is
80 .
RMON Status Remote monitoring (RMON) of the Switch is Enabled or Disabled here.
Link Aggregation
Algorithm 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).
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.
Authentication
Protocol 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 .
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.
