EVC CONTROL LIST CONFIGURATION

Configuration Ethernet Services
This page displays current EVC configurations. On this system, only Provider Bridge
based EVCs are supported.
EVC ID
The EVC ID identifies the EVC. The range is from 1 through 256.
Name
The name for the EVC.
VID
The VLAN ID in the PB network. It may be inserted in a C-tag, S-tag or S-custom tag
depending on the NNI port VLAN configuration. The range is from 1 through 4095.
IVID
The Internal/classified VLAN ID in the PB network. The range is from 1 through 4095.
Learning
The learning mode for the EVC controls whether source MAC addresses are learned for
frames matching the EVC. Learning may be disabled if the EVC only includes two UNI/NNI
ports. The possible values are:
Enabled: Learning is enabled (MAC addresses are learned).
Disabled: Learning is disabled (MAC addresses are not learned).
Inner Tag Type
The inner tag type is used to determine whether an inner tag is inserted in frames forwarded to
NNI ports. The possible values are:
None: An inner tag is not inserted.
C-tag: An inner C-tag is inserted.
S-tag: An inner S-tag is inserted.
S-custom-tag: An inner tag is inserted and the tag type is determined by the VLAN port
configuration of the NNI.
Inner VID Mode
The inner VID Mode affects the VID in the inner and outer tag. The possible values are:
Normal: The VID of the two outer tags aren't swapped.
Tunnel: The VID of the two outer tags are swapped, so that the VID of the outer tag is taken
from the Inner Tag configuration and the VID of the inner tag is the EVC VID. In this mode,
the NNI ports are normally configured to do EVC classification based on the inner tag.
Inner Tag VID
The Inner tag VLAN ID. The allowed range is from 0 through 4095.
