VID ACL (Access control list).
Access VLANs allowed for each port. This
parameter behaves like a filter with regard to packets accepted on the Port level, and
only packets with a VLAN identifier included in the list will be processed for
transmission and reception purposes. All the packets have a VLAN identifier, either
because it was included when they were received (tagged frames) or because it was
assigned by the input port at the time of reception, with the
VID
parameter being
assigned to the port in the latter case. The special value
all
signifies that the filter is
not active. The default value is auto, and it implies that only those packets belonging
to the VLAN assigned to the port will be accepted, that is, the filter is not active.
A group of discreet vlans is configured with the identifier of each one, separated by a
comma, without spaces. If a range is to be included, the initial and final vlan
identifiers are separated by a dash. Example: in equipment with the
vlan1
to
vlan3
and
vlan5
defined, the group of numerical identifiers will be
1-3,5
.
For the interfaces operating in QinQ Core mode, the VLAN identifiers that are
included in this parameter determine which QinQ Access interfaces are to be
served through each interface, those whose VID parameter is part of the ACL.

Description.
A mnemonic descriptive field available to users.
•
LAG.
Link group identifier. It sets whether the interface is part of a group of
interfaces operating as aggregate interface or not. The value of the parameter, if it is
other than
none
, indicates in which of the 8 possible groups the interface will be
integrated.
A group of LAG interfaces is to be considered as a single interface, so that the
links of the same group are not to be considered a loop by the STP, allowing a
bandwidth increase between devices while keeping some level of automatic
redundancy. All the interfaces within a group must be interconnected to the same
end devices.
•
LAG leader.
For proper operation of the aggregate interfaces, all interfaces
belonging to the same group must match in their configuration parameters. It is
necessary to choose a
Leader
within the group to determine which set of parameters
will be used for all the interfaces included in the group. In case for multiple selection,
the last that is found is taken as Leader, ignoring the rest.
If interfaces are configured as members of a group but none of the interfaces is
selected as Leader of it, the group will not be effective.
