DES-3028 DES-3028P DES-3052 DES-3052P Layer 2 Fast Ethernet Managed Switch
Rate
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.
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
located in the IGMP Snooping folder contained in the L2 Features 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.
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. TCP ports are numbered between 1 and 65535. 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. TCP ports are numbered between 1 and 65535. The "well-known" TCP
port for the Web 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, (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 802.1x authentication protocol on the Switch is set to RADIUS Eap and cannot be
altered.
Syslog Status
Enables or disables Syslog State; default is Disabled.
Port Security Trap
Log
Toggle this setting to enable or disable the port security trap log feature. The default is
Disabled.
ARP Aging Time
(0-65535)
The user may globally set the maximum amount of time, in minutes, an Address Resolution
Protocol (ARP) entry can remain in the Switch’s ARP table, without being accessed, before it
is dropped from the table. The value may be set in the range of 0 to 65535 minutes with a
default setting of 20 minutes.
GVRP
Use this pull-down menu to enable or disable GVRP on the Switch.
Click Apply to implement changes made.
