Port-Based Virtual LANs (Static VLANs)

DHCP or Bootp on different VLANs do not result in conflicting configuration values for the switch. The primary VLAN is the VLAN the switch uses to run and manage these features and data. In the factory-default configuration, the switch designates the default VLAN (DEFAULT_VLAN) as the primary VLAN. However, to provide more control in your network, you can designate another VLAN as primary. To summarize, designating a non-default VLAN as primary means that:

The stacking feature runs on the switch’s designated primary VLAN instead of the default VLAN

The switch reads DHCP responses on the primary VLAN instead of on the default VLAN.

The default VLAN continues to operate as a standard VLAN (except, as noted above, you cannot delete it or change its VID).

Any ports not specifically assigned to another VLAN will remain assigned to the Default VLAN, regardless of whether it is the primary VLAN.

Candidates for primary VLAN include any static VLAN currently configured on the switch. To display the current primary VLAN, use the CLI show vlan command.

If you manually configure a gateway on the switch, it will ignore any gateway

 

address received via DHCP or Bootp.

 

 

Per-Port Static VLAN Configuration Options

The following figure and table show the options you have for assigning individual ports to a static VLAN. Note that GVRP, if configured, affects these options and VLAN behaviour on the switch. The display below shows the per- port VLAN configuration options. Table 9-7briefly describes these options.
