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 maximum number of S-VLANs that you can create per I/O module or IOA 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 the I/O module or IOA, knowing that no more than
the maximum number of supported PPP sessions can be connected to the router at
any one time.
For information about the module combinations that support S-VLAN oversubscription,
see “S-VLAN Oversubscription” on page 188 in “Configuring VLAN and S-VLAN
Subinterfaces” on page 169.
For specific information about the maximum number of S-VLANs supported per I/O
module or IOA and the maximum number of PPP interfaces and PPPoE subinterfaces
supported per line module, see

.
NOTE:
S-VLAN oversubscription is not currently supported for S-VLANs configured
over bridged Ethernet interfaces.
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 whether one or two
IOAs are installed. For more information about configuration options for the ES2-S1
GE-4 IOA, see chapter Configuring Ethernet Interfaces in

atm pvc
Use to configure a PVC on an ATM interface. Specify one of the following
encapsulation types:
■
■
aal5autoconfig
—Enables autodetection of the 1483 encapsulation (LLC/SNAP
or VC multiplexed).
■
aal5snap
—Specifies a logical link control (LLC) encapsulated circuit; the
LLC/Subnetwork Access Protocol (LLC/SNAP) header precedes the protocol
datagram.
