EVCs
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
.
