CR00018346 VLAN - This enhancement adds a new parameter nestedoverride to the
command add vlan port.
The nestedoverride parameter allows you to add the port to a non-nested
VLAN as a tagged port even if the port has already been configured as a
customer port in a nested VLAN. The vlan parameter specifies the non-
nested VLAN to which you want to add the port. You must also specify
frame=tagged. The port will behave as a normal customer port for the
nested VLAN, and an egress-only port for the non-nested VLAN:
■ Frames received on the port and tagged for the nested VLAN will be sent
to the core ports of the nested VLAN, as normal.
■ Frames received on the port and tagged for the non-nested VLAN will
be sent to the core ports of the nested VLAN, and will not be sent to
other ports of the non-nested VLAN.
■ IGMP frames received on the port and tagged for the non-nested VLAN
will be processed according to the IP multicasting configuration, instead
of being discarded.
■ Frames received on other ports of the non-nested VLAN will be
transmitted from the port as tagged frames of the non-nested VLAN
according to the FDB/multicast rules.
The nestedoverride parameter creates a non-standard configuration, and
care should be taken when using this parameter in a live network. The
nestedoverride and uplink parameters are mutually exclusive and cannot
be specified in the same command.
An example configuration would be:
create vlan=v22 vid=22 nested
create vlan=v20 vid=20
add vlan=v22 port=1 nested=customer
add vlan=v20 port=1 frame=tagged nestedoverride
