•  VLAN Information - Displays the membership information for all VLANs.  

Note: This page displays an overview of the switch configuration. To change the switch 
configuration, use the Web Management-Interface pages referenced on this page. 

There are two main buttons associated with this page:  
 

•  HELP - Displays this window.  
•  REFRESH - Refreshes the page with the current switch configuration and status 

information.  

This section contains general information about the switch. System Name, System Location, 
and System Contact are set in the SYSTEM > Name page. The Software Version changes 
when a new version of software is updated on the switch from the SUPPORT > Update 
Software page. The Number of Ports, Hardware Version, and Serial Number values are 
created when the switch is manufactured and cannot be changed.  

IP Address, Subnet Mask and Gateway IP Address are set from the SYSTEM > IP Address 
page. Management VLAN and MAC Address are fixed during manufacture and are provided 
here for information. 

This table contains one row for each port on the switch. Each row is divided into eight columns 
as follows:  
 

•  Port - The front-panel port number.  
•  Type - All ports on this switch are 10/100/1000BASE-T.  
•  Link Status - Up indicates that the port is connected to another device. Down indicates 

there is no connection. The front-panel "image" that is always visible at the top of the 
page, also displays this information.  

•  Speed/Duplex Status - An indication of the speed and duplex setting of the port. This is 

a number, the speed in Mbps, followed by either FDX for full-duplex or HDX for half-
duplex. This can be changed on the PORTS > Configuration page.  

•  Flow Control Status - Enabled indicates that Flow Control has been enabled on the 

PORTS > Configuration page.  

•  Auto-negotiation - Auto-negotiation is Enabled by default and is only Disabled when 

a Speed/Duplex setting other than Auto is selected on the PORTS > Configuration 
page.  

•  Frame Type - Tagged means that the port will only send and receive VLAN-tagged 

frames. When set to All the port will also send and receive untagged packets. See VLANS 
> Port Config for more information.  

•  PVID - The Port VLAN ID. When Frame Type is set to All, untagged packets arriving on 

the port will be associated with this VLAN. See VLANS > Port Config for more 
information.
