36CHAPTER 4: USING THE CENTRAL CONFIGURATION MANAGER

This window has six tabs across the top--General Configuration, Priority & VLAN Configuration, Security Configuration, SNMP Configuration, Advanced Configuration, and System Log Settings. Check the box next to any setting you want to change from within these five areas.

The bottom of the window has buttons labeled Load and Save. The Save operation lets you save an IntelliJack configuration profile. You can then use the Load button to apply the configuration profile to one or more IntelliJacks.

If you wanted to send a single configuration to one or more IntelliJacks, you would make the configuration changes in this window and click Save. Then you could select a list of IntelliJacks from the main Configuration Manager window and click Load, choose the file, and click OK. This would send the configuration to all of the IntelliJacks that you selected.

General Configuration

3Make sure the General Configuration tab is selected.

Identification Settings

4To change or set the Group Name, check the box next to that field. You can set a Group Name to anything you want, up to 128 characters.

5Change or set the Location Name by checking the box next to that field and entering up to 128 characters.

6Configure the DHCP setting to the desired state.

Hardware Settings

7Change the Port state of any of the IntelliJack’s ports by selecting the Port tab and checking the box next to the characteristic you want to modify. Then select a value from the drop list.

Forwarding (Enable) is the default setting for the Port State. The other option is Blocking (Disable). Forwarding (Enable) allows traffic to pass through the individual ports. By setting the Port State to Blocking (Disable), you can block any traffic from passing.

You may want to set the Port State to Blocking (Disable) when you want to restrict access to your LAN at the location where the IntelliJack is installed. This might be an appropriate option in a public use area such as a lobby, conference room, or classroom. Using the Calendar function, you can schedule the Port State for Forwarding (Enable) or Blocking (Disable) at specified times and dates.

8To change the Link State setting, click the box and select an option from the drop list.

Auto Negotiation is the default setting and the de facto setting for most network equipment because it is the most flexible option. It automatically configures a networked device based on the speed and duplex of the upstream device it is plugged into. This is especially useful when you do not know the configuration (speed/duplex) of all devices connected to the network.

Be advised, however, that not all network interface cards (NICs) use the standard auto-negotiation algorithm, and it may be necessary to force the speed and duplex of the PAN port to match the speed and duplex of the attached NIC.

9The next two settings apply not to a specific port, but to the IntelliJack as a whole. By default, the Central Configuration Manager will display a count of good
