provider bridge is to recognize and use VLAN tags so that the VLANs in the MAN space can be used independent of the customers’
VLANs. This is accomplished by adding a VLAN tag with a MAN-related VID for frames entering the MAN. When leaving the MAN,
the tag is stripped and the original VLAN tag with the customer-related VID is again available.
This provides a tunneling mechanism to connect remote costumer VLANs through a common MAN space without interfering with
the VLAN tags. All tags use EtherType
0x8100
or
0x88A8
, where 0x8100 is used for customer tags and 0x88A8 are used for service
provider tags.
In cases where a given service VLAN only has two member ports on the switch, the learning can be disabled for the particular VLAN
and can therefore rely on flooding as the forwarding mechanism between the two ports. This way, the MAC table requirements is
reduced.
Global VLAN Configuration
The Global VLAN Configuration screen in

The Page includes the following fields:
Object
Description
Allowed Access
VLANs
This field shows the allowed Access VLANs, it only affects ports configured as
Access ports. Ports in other modes are members of all VLANs specified in the
Allowed VLANs field.
By default, only VLAN 1 is enabled. More VLANs may be created by using a list
syntax where the individual elements are separated by commas. Ranges are
specified with a dash separating the lower and upper bound.
The following example will create VLANs 1, 10, 11, 12, 13, 200, and 300:
1,10-13,200,300
. Spaces are allowed in between the delimiters.
Ethertype for Custome
S-ports
This field specifies the ethertype/TPID (specified in hexadecimal) used for
Custom S-ports. The setting is in force for all ports whose Port Type is set to
S-Custom-Port.
