Another reason why you might want to reject the additional ports recommended by 3Com Network Director is if you do not require any IP routing for your VLAN. In this situation you should use the Remove button to remove the ports 3Com Network Director has determined are required to connect the VLAN to the nearest Layer 3 switch.

Checking the VLAN limit

When you click the Next button on this wizard panel, 3Com Network Director will check that the creation of a new VLAN will not exceed the VLAN limit of any of the switches to be configured. For example, the 3Com Switch 3300 supports up to 16 VLANs. See “Reference B” on page 575. If the VLAN limit of any switch will be exceeded, an error message box will be shown and you will be prevented from continuing.

Configuring unsupported devices

3Com Network Director will automatically create VLANs on supported switches – see “Reference A” on page 574 for a list of supported switches. If the switches that the new VLAN is to be created on include switches that 3Com Network Director cannot automatically configure, e.g. non-3Com switches, then you will have to configure these manually using the switch’s Telnet interface, Web management interface, or another configuration tool. The next wizard stage lists those devices that you will need to manually configure:
