Modifying VLAN properties
To modify the properties of a configured VLAN, do the following from the VLAN
Configuration tab:
1. In the NICs Available list, select the adapter that has the VLAN you want to modify.
The adapter is highlighted when your selection is made.
2. Click Properties.
In the VLAN Properties window, you can modify one of the following parameters:
• VLAN ID: You must assign a unique identification number to each VLAN you
create. Even though the maximum number of VLANs that can be configured on
each adapter is 64, any particular VLAN can be assigned an identification
number between 1 and 4094.
The VLAN tagging format follows the guidance provided in IEEE 802.1Q-
1998. Be sure that there are no spaces, blank lines, or extra characters. The
identifier can be entered in decimal (for example, 383), octal (for example,
0577), or hexadecimal (e.g. 0x17F) format.
• VLAN Name: This optional identifier appears only in the Netfinity Gigabit
Ethernet Adapter Device Driver Properties window.
3. When you are finished modifying this VLAN, click OK.
4. Repeat steps 1 to 3 for each VLAN you want to modify.
5. When you are finished configuring VLANs, click Close in the Netfinity Gigabit
Ethernet Adapter Device Driver Properties window to accept the changes.
6. In the Network window, click Close.
7. When you are prompted to restart your computer, click Yes.
Your computer restarts, using the new configuration settings.
Note: If you modify any optional configuration parameters (Failover Team or
VLAN), you must restart your computer before the changes will take effect. If
you make changes and do not restart, you might experience configuration
problems. If no configuration changes have been made, you can click No to
close the configuration session without restarting your computer.
Troubleshooting
This section describes techniques for troubleshooting your Netfinity Gigabit Ethernet
Adapter and correcting some types of problems.
Internal loopback test (Windows NT)
The Tech Support tab in the Netfinity Gigabit Ethernet Adapter Device Driver properties
window displays information about how to contact the IBM HelpCenter and access the
Windows NT-based internal loopback diagnostic test for the adapter. Use the internal
loopback test to verify that the adapter firmware is configured and operating correctly.
To perform the internal loopback diagnostic test on an adapter, do the following.
1. Click Start
