S-VLAN entering the provider-nni port will be processed based on the VLAN
configuration of the port.
Untagged or C-VLAN entering a provider-nni port will be considered as
untagged (as they have no S-VLANs) and will be tagged internally using S-
VLAN PVID (default is S-VLAN ID 1).
o
Customer UNI (CEP - Customer Edge Port): port that has a C component
associated with it and is used for C-VLANs processing.
C-VLAN entering a customer-uni port will be processed based on the VLAN
configuration on the ports.
Untagged or S-VLAN entering a customer-uni port will be considered as
untagged (as they have no C-VLANs) and will be tagged internally using C-
VLAN PVID (default is C-VLAN ID 1).
o
Customer NNI (CNP - Customer Network Port): port that doesn’t have a C
component associated with it but presents a simplified model for C-VLANs
processing and transparent bridge implementation.
As in provider-nni, untagged or C-VLAN entering a customer-nni port will be
considered as untagged (as they have no S-VLANs) and will be tagged
internally using S-VLAN PVID (default is S-VLAN ID 1).
Processing of specific C-VLANs is done by mapping them to specific S-VLAN
IDs using C-VLANs Registration.
By default, all Ethernet ports are configured as Customer NNI ports. That means all
untagged and C-VLANs are carried transparently to all ports.
Bridge-Port (PVID)
A VLAN ID which will be assigned to an untagged frame or a priority-tagged frame, (the
VID is set to 0 indicating that the frame does not belong to any VLAN and only PCP field
is relevant), which enters to the bridge through this port. The special value “undef”
cannot be used as PVID.
o
The default PVID is 1 with priority 0:
o
Untagged frame entering the S1 component (or provider-nni) will be tagged
with S-VLAN ID 1.
o
Untagged frame entering a C component (or customer-uni) will be tagged
with C-VLAN ID 1.
8.3.1
VLAN Configuration
The system’s default configuration is transparent bridge, meaning all untagged, C -
VLANs and S-VLANs can pass transparently to all ports.
The
VLAN
section displays the current processing of VLANs (C-VLANs and S-VLANs):
