provide you with the flexibility of having the dynamic interface column created
automatically only when the subscriber logs in.
Figure 61 on page 655 displays the relationship between the central office, digital subscriber
line access multiplexers (DSLAMs), and subscribers. The subscribers are connected to
the DSLAMS through Gigabit Ethernet interfaces.
Figure 61: Dynamic VLAN Subinterfaces for Subscribers
For example, if an S-VLAN is assigned at the DSLAM, and each DSLAM subscriber at the
DSLAM is assigned a unique VLAN ID, the JunosE Software dynamically constructs a
VLAN-based interface column using that S-VLAN/VLAN ID pair when the subscriber logs
in.
For more information about the attributes of VLAN and S-VLAN subinterfaces, see
"Configuring VLAN and S-VLAN Subinterfaces" on page 167.

VLAN Base Profiles

To configure a dynamic VLAN subinterface over a static VLAN major interface, you must
create a base profile. The base profile includes one or more of the following attributes
for the VLAN subinterface:
advisory-rx-speed—Sets an advisory receive speed for VLAN subinterfaces that are
created with this profile. For information, see "vlan advisory-rx-speed" on page 669.
advisory-tx-speed—Sets an advisory connect speed for VLAN subinterfaces that are
created with this profile. For information, see "vlan advisory-tx-speed" on page 669.
