S-VLAN Oversubscription

When you configure S-VLAN subinterfaces over Ethernet interfaces to support dynamic
PPPoE subinterfaces, you can take advantage of S-VLAN oversubscription.
The following module combinations support S-VLAN oversubscription:
The maximum number of S-VLANs that you can create per I/O module with PPPoE
major interfaces stacked over them is greater than the maximum number of dynamic
PPPoE subinterfaces. The maximum number of PPP interfaces supported per line
module is directly proportional to the maximum number of PPPoE subinterfaces.
As a result, you can oversubscribe S-VLANs by configuring up to the maximum
number of S-VLANs supported on these I/O modules, knowing that no more than
the maximum number of supported PPP sessions can be connected to the router at
any one time.
For configuration instructions, see "Configuring Dynamic PPPoE over Static PPPoE
with Ethernet and S-VLAN Interface Columns" on page 492 in "Configuring Dynamic
Interfaces" on page 465.
For specific information about the maximum number of S-VLANs supported per I/O
module and the maximum number of PPP interfaces and PPPoE subinterfaces
supported per line module, see JUNOSe Release Notes, Appendix A, System Maximums.
NOTE: The E120 and E320 routers can support up to two IOAs per line module. This
maximum number of S-VLANs per line module does not change if one or two IOAs
are installed.

Monitoring VLAN and S-VLAN Subinterfaces

This section explains how to display bit rate and packet rate statistics for VLAN
subinterfaces and use the show commands to display the physical characteristics
and the configured settings for VLAN and S-VLAN subinterfaces.
