Static Virtual LANs (VLANs) Configuring VLANs Changing the Number of VLANs Allowed on the Switch. In the default VLAN configuration, the switch allows a maximum of 256 VLANs. You can specify any value from 1 to 256 for the HP 6120G/XG switch and from 1 to 1024 for the HP 6120XG switch. Syntax: max-vlans < 1-256 > max-vlans Specifies the maximum number of VLANs to allow. (If GVRP is enabled, this setting includes any dynamic VLANs on the switch.) As part of implementing a new setting, you must execute a write memory command (to save the new value to the startup-config file) and then reboot the switch. Note: If multiple VLANs exist on the switch, you cannot reset the maximum number of VLANs to a value smaller than the current number of VLANs. For example, to reconfigure the switch to allow 10 VLANs: Note that you can execute these three steps at another time. Figure 2-23. Example of Command Sequence for Changing the Number of VLANs Changing the Primary VLAN. In the default VLAN configuration, the portbased default VLAN (DEFAULT_VLAN) is the Primary VLAN. However, you can reassign the Primary VLAN to any port-based, static VLAN on the switch. (For more on the Primary VLAN, refer to "The Primary VLAN" on page 2-47.) To identify the current Primary VLAN and list the available VLANs and their respective VIDs, use show vlans. Syntax: primary-vlan < vid | ascii-name-string > Reassigns the Primary VLAN function. Re-assignment must be to an existing, port-based, static VLAN. (The switch will not reassign the Primary VLAN function to a protocol VLAN.) If you re-assign the Primary VLAN to a non-default VLAN, you cannot later delete that VLAN from the switch until you again re-assign the Primary VLAN to another port-based, static VLAN. 2-35
