a single port which is nominated for the purpose, known as the downlink.
Whether downlinks are supported by a particular unit can be determined by
looking at the Fwding Action field on the LinkSwitch 1000 Configuration view.
This field displays the unit on which this VLAN's downlink resides. It may be
changed only when the Row Status is Not In Service. If this VLAN does not
have a downlink, either because the unit does not support them or because
one has not been configured, this field and PortID are both zero.
Port ID
This field displays the port on which this VLAN's downlink resides. This field
displays the specific port on the unit displayed in the UnitID field.
Row Status
The VLAN table contains a row for each of the 16 VLANs that exist on a unit.
VLANs cannot be created or deleted, so sets of this object with values Create
And Go, Create And Wait, or Destroy will be rejected. A get of this object will
only return the values Active or Not In Service.
Only if the status of the row is Not In Service will sets of the downlink unit or
port be successful. Changes will not take effect until the Row Status is
changed to Active. Thus, to change the downlink for a VLAN the network
manager must first set Row Status to Not In Service, set the new values for
the downlink, then set Row Status back to Active. This will fail in the
following circumstances:
• The unit does not support downlinks (the value of Fwding Action is not
Forward to Downlink).
• The port does not exist.
• The value of Mode for the port is not Multiplex and the port is not
assigned to the VLAN.
