Creating VLAN Subranges That Include Static VLAN Subinterfaces

You can configure a bulk-configured VLAN subrange that includes the VLAN ID belonging to an existing VLAN on a static VLAN subinterface. This example is essentially the reverse of the procedure in Creating Static VLAN Subinterfaces Within VLAN Subranges.

To create a VLAN subrange that includes a static VLAN subinterface:

1. Create the VLAN major interface.

   host1(config)#interface gigabitEthernet 3/1

   host1(config-if)#encapsulation vlan

2. Specify a static VLAN subinterface.

   host1(config-if)#interface gigabitEthernet 3/1.201

3. Do one of the following:
   • Assign a VLAN ID for the subinterface.

     host1(config-if)#vlan id 201

   • Assign a VLAN ID and the optional unique MAC address for the subinterface.

     host1(config-if)#vlan id 201 mac-address 0090.1a01.1234

4. Create a bulk-configured VLAN range that includes the VLAN ID of the previously configured VLAN. In this example, the VLAN range 100–250 includes VLAN ID 201.

   host1(config)#interface gigabitEthernet 3/1

   host1(config-if)#vlan bulk-config test2 vlan-range 100 250

5. To fully configure the VLAN subinterface, assign an IP address or make it unnumbered.

   host1(config-if)#ip unnumbered loopback 0

encapsulation vlan

• Use to configure VLAN as the encapsulation method on an interface.
• Issuing this command creates the VLAN major interface.
• Example

  host1(config-if)#encapsulation vlan

• Use the no version to disable VLAN encapsulation on the interface.
• See encapsulation vlan.

interface gigabitEthernet

interface tenGigabitEthernet

• Use to select a Gigabit Ethernet interface or a 10-Gigabit Ethernet interface.
• For information about specifying a Gigabit Ethernet or 10-Gigabit Ethernet interface, see interface gigabitEthernet and interface tenGigabitEthernet.
• Examples

  host1(config)#interface gigabitEthernet 1/0

  host1(config)#interface gigabitEthernet 4/0/1

  host1(config)#interface tenGigabitEthernet 4/0/1

• Use the no version to remove IP from an interface.
• See interface gigabitEthernet.
• See interface tenGigabitEthernet.

ip unnumbered

• Use to configure an unnumbered IP interface.
• This command enables IP processing on an interface without assigning an explicit IP address to the interface.
• You must specify an interface location, which is the identifier of another interface on which the router has an assigned IP address. This interface cannot be another unnumbered interface.
• Examples

  host1(config-if)#ip unnumbered fastEthernet 3/0

  host1(config-if)#ip unnumbered loopback 10

• Use the no version to disable IP processing on the interface.
• See ip unnumbered.

vlan bulk-config

• Use to create a bulk-configured VLAN range on a static VLAN major interface for use by a dynamic VLAN subinterface.
• For detailed information about how to use this command, see vlan bulk-config.
• Example

  host1(config)#vlan bulk-config test1 svlan-range 200 250 2 2

• Use the no version to remove the specified VLAN range from the VLAN major interface, to remove the specified subranges from the specified VLAN range, or to remove all subranges from the specified VLAN range. The no version also removes any overriding profile assignments for VLAN IDs or S-VLAN IDs within the deleted VLAN range or VLAN subrange.
