56.9 Transparent LAN Service (TLS)
Transparent LAN Service (also known as VLAN stacking or Q-in-Q) allows a service provider
to distinguish multiple customers VLANs, even those with the same (customer-assigned)
VLAN ID, within its network.
Use TLS to add an outer VLAN tag to the inner IEEE 802.1Q tagged frames that enter the
network. By tagging the tagged frames (“double-tagged” frames), the service provider can
manage up to 4,094 VLAN groups with each group containing up to 4,094 customer VLANs.
This allows a service provider to provide different services, based on specific VLANs, for
many different customers.
A service provider’s customers may require a range of VLANs to handle multiple
applications. A service provider’s customers can assign their own inner VLAN tags to traffic.
The service provider can assign an outer VLAN tag for each customer. Therefore, there is no
VLAN tag overlap among customers, so traffic from different customers is kept separate.
Before the IES-1248 sends the frames from the customers, the VLAN ID is added to the
frames. When packets intended for specific customers are received on the IES-1248, the outer
VLAN tag is removed before the traffic is sent.
See
for an example.
ppp lcp config-
request
=
The number of config-request PDUs received by the IES-1248
from the CPE (client) device.
ppp lcp echo-
request
=
The number of echo-request PDUs received by the IES-1248
from the CPE (client) device.
ppp lcp echo-
reply
=
The number of echo-reply PDUs received by the IES-1248 from
the CPE (client) device.
pppoe padi
=
The number of padi PDUs sent by the IES-1248 to the BRAS.
pppoe pado
=
The number of pado PDUs sent by the BRAS to the IES-1248.
pppoe padr
=
The number of padr PDUs sent by the IES-1248 to the BRAS.
pppoe pads
=
The number of pads PDUs sent by the BRAS to the IES-1248.
pppoe padt
=
The number of padt PDUs sent and received by the IES-1248.
pppoe srvcname
error
=
The number of service name errors; for example, the IES-1248’s
specified service is different than the BRAS’s setting.
pppoe ac system
error
=
The number of times the access concentrator experienced an
error while performing the Host request; for example, when
resources are exhausted in the access concentrator. This value
does not include the number of times the IES-1248 checks the
AC name field in the BRAS's reply PDU and finds a mismatch,
however.
pppoe generic
error
=
The number of other types of errors that occur in the PPPoE
session between the IES-1248 and the BRAS.
