Admin State

This attribute is the user‐configurable state of the EVC map. Table F‐7 lists the available
options.

Enabled
Disabled

UNI

This attribute is the physical interface connected to the Customer Equipment (CE) or
subscriber. It is the demarcation point of Adtran equipment to the subscriber premises and is
the gateway into the EVC. The protection of the EVC is performed at the UNI so that assump‐
tions can be made within the EVC.

CE-VLAN-ID

This attribute is the VLAN ID of the outermost VLAN tag of the Ethernet frame received at the
UNI port. If the value is unspecified, then the EVC map applies to the remainder of customer
frames received that are not affected by other EVC maps on the same UNI port.

CE-VLAN-Pri

This attribute is a range of P‐bit values of the outermost VLAN tag of the Ethernet frame
received at the UNI port. This attribute can only be specified if the DSCP attribute is not
specified. The value is entered as a character string of the allowable P‐bit values.

Definition
The CE‐VLAN‐ID conflicts with the VID that is actively used for
managing the system and the two are sharing the same port..
The EVC is not preserving CE‐VLAN‐ID and has at least two
EVC maps connected to it with different values for the CE‐
VLAN‐ID attribute. For an EVC forwarding traffic in the MEN‐
to‐UNI direction, the switch uses the CE‐VLAN‐ID value of the
EVC map. There is no way for the switch to determine what
value to apply if the values vary across connected EVC maps.
The UNI of the EVC map is used by a MEN‐port of an enabled
EVC.
