Configuration guidelines
When you configure VLANs, follow these guidelines:
• As the default VLAN, VLAN 1 cannot be created or removed.
• You cannot manually create or remove VLANs reserved for special purposes.
• H3C recommends that you set the same PVID for local and remote ports.
• Make sure that a port is assigned to its PVID. Otherwise, when the port receives frames tagged with
the PVID tag or untagged frames (including protocol packets such as STP BPDUs), the port filters out
these frames.
• As shown in Figure 16 , on the VLAN configuration page, when you type a VLAN range in the VLAN
Range field and then click Select, the page lists information about all the VLANs within this range,
which makes the operation much easier when the firewall contains a large number of VLANs. After
you click Delete, all VLANs within this range will be removed.
