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 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, the outer VLAN tag is removed
before the traffic is sent.
See Section 25.1.6 on page 182 for more on VLAN TLS and command examples.
The following table describes commonly used parameter notation for these commands.
This table describes the commands.

VLAN TLS Command Parameters
NOTATION DESCRIPTION
svid
The SVID (Subscriber VLAN ID) 1-4093.

VLAN TLS Commands Summary
COMMAND DESCRIPTION M P
interface dsl < slot/portlist >
Configures the specified DSL ports. C 13
exit
Leaves the DSL port configuration. C 13
vlan tls svlan < svid >
spbit < spbit > [force-
spbit]
Enables Transparent LAN service on the specified DSL ports. In PTM
mode, a DSL port is a logical Ethernet port. The IES adds the S tag
(SVID) to packets from the DSL ports before forwarding them through
an uplink interface.
spbit
: 0-7, if a priority bit is not assigned, the S priority bit is copied
from the customer priority bit.
[force-spbit]
if not specified, only untagged frames will adopt the S
priority bit in upstream traffic. If specified, untagged, priority tagged,
and C tagged frames will adopt the S priority bit in upstream traffic.
C 13
no vlan tls
Disables Transparent LAN service on the specified DSL ports. C 13
vlan tls atm-vc < vpi >/
< vci > svlan < svid > spbit
< spbit > [force-spbit]
Enables Transparent LAN service on the specified DSL ATM virtual
circuit. In ATM mode, an ATM PVC is a logical Ethernet port. The IES
adds the S tag (SVID) to packets from the DSL ATM virtual circuits
before forwarding them through an uplink interface.
spbit
: 0-7, if a priority bit is not assigned, the S priority bit is copied
from the customer priority bit.
force-spbit
: if not specified, only untagged frames will adopt the S
priority bit in upstream traffic. If specified, untagged, priority tagged,
and C tagged frames will adopt the S priority bit in upstream traffic.
C 13
no vlan tls atm-vc < vpi >/
< vci >
Disables Transparent LAN service on the specified DSL ATM virtual
circuit. C 13
