Configuring VLAN Dynamic Subinterfaces
Configure profiles containing characteristics for the dynamic upper-interface
encapsulation types to be created over the dynamic VLAN subinterface.
These profiles are referenced in the base profile for the dynamic VLAN
subinterface as nested profile assignments. For detailed instructions on creating
profiles, see "Configuring a Dynamic Interface from a Profile" on page 563 in
"Configuring Dynamic Interfaces" on page 515.
(Optional) Create the profile for an upper-interface encapsulation type, and
include additional profile characteristics for other encapsulation types as needed.
Perform this step if you want to create a nested profile assignment in Step 5.
host1(config)#profile myIpProfile
host1(config-profile)#ip inactivity-timer 200
host1(config-profile)#ip auto-configure ip-subscriber include-primary
Create the base profile for the dynamic VLAN subinterface by assigning the
profile a name.
host1(config)#profile vlanBaseProfile
This command accesses Profile Configuration mode, which enables you to
configure attributes in the base profile.
Define attributes for the VLAN subinterface in the base profile.
a. Configure the VLAN major interface for autodetection of the PPPoE
upper-interface encapsulation type.
b. Configure the VLAN subinterface for autodetection of the IP upper-interface
encapsulation type.
c. Configure an Ethertype value for any S-VLANs configured on the VLAN.
host1(config-profile)#vlan auto-configure pppoe
host1(config-profile)#vlan auto-configure ip
host1(config-profile)#svlan ethertype 8100
(Optional) In the base profile, create nested profile assignments for the
upper-interface encapsulation types.
For example, the following command configures nested profile assignments for
the IP upper-interface encapsulation types.
host1(config-profile)#vlan profile ip myIpProfile
Exit Profile Configuration mode.
Configure the VLAN major interface.
host1(config)#interface gigabitEthernet 5/0
host1(config-if)#encapsulation vlan
Configure a VLAN range on the major VLAN interface, and assign a name to this
range.
