depending on the NNI port VLAN configuration. The range is from 1through 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.
 Inner Tag PCP/DEI Preservation
The inner tag PCP and DEI preservation. The possible values are:
Preserved: The inner tag PCP and DEI is preserved.
Fixed: The inner tag PCP and DEI is fixed.
