ifMainBrgPortType

The Bridge port type of this specified switch port.
Bridge Port type can be specified only for switch ports and not for 
router ports, IVR interfaces and I-LAN Interfaces.
              
providerNetworkPort - Port Connected to a single Provider.
SVLAN Classification is based on only the PVID configured for the 
port for untagged packets.
              
customerNetworkPortPortBased - Port in the S-VLAN component that 
can transmit or received frames for single customer. 
All packets received on this port, are mapped to one single service 
instance identified by the PVID of that Port.
Acceptable Port Type will be always Admit only Untagged or Priority 
Tagged Frames on this port.
              
customerNetworkPortStagged - Port in the S-VLAN component that 
can transmit or received frames for single customer. 
VLAN classification on this interface will be based on the S-tag 
received or on the PVID of the port. Ingress Filtering will be 
always enabled on this port.
              
customerEdgePort - Port in a Provider Edge Bridge connected to a 
single customer. Multiple services can be provide on this port.
The Packets received on this interface will be first classified 
to a CVLAN. CVLAN classification can be based on the Vid 
in the C-Tag present in the packet (if it C-tagged packet) or from 
the pvid of the port. Service instance selection (S-VLAN selection) 
for a frame is done based on the entry present in the C-VID 
registration table for the pair (C-VID, reception Port). 
CustomerEdgePort configuration is allowed only in Provider Edge 
Bridges.
              
propCustomerEdgePort - Port connected to a single customer, where 
multiple services can be provided based on only Proprietary SVLAN 
classification tables. S-VLAN classification will not happen based on
C-VID registration table on this port. propCustomerEdgePort 
configuration is allowed only in Provider Edge Bridges.
              
propCustomerNetworkPort - Port connected to a single customer, where 
multiple service can be provided based on CVLANs by assigning one of 
the Proprietary SVLAN classification tables to this port. The 
services can also be assigned using other proprietary SVLAN 
classification tables where CVLAN is not the index of the table.
              
propProviderNetworkPort - Port connected to a Q-in-Q Bridge located
inside Provider Network. This port is part of S-VLAN component. 
If packets to be tagged and sent out of this port will have 0x8100
as the ether type. Similarly pakcets with standard Q tag (ether type
as 0x8100) received will be considered as S-Tagged packets. 
              
customerBridgePort - Type of the port to be used in customer 
bridges as well in Provider(Q-in-Q) bridges. This type is not valid 
in Provider Core bridges as well as Provider Edge bridge. 
               
 customerNetworkPortCtagged - Port in the I component that 
can transmit or received frames for single customer. 
VLAN classification on this interface will be based on the C-tag 
received or on the default CVID of the port. Ingress Filtering will be 
always enabled on this port.
               
 virtualInstancePort - A Bridge Port on an I-component in a Backbone Edge Bridge 
 that provides access to a single backbone service instance.
               
 providerInstancePort - The set of Virtual Instance Ports that are supported
 by a single instance of the ISS.
               
 customerBackbonePort	- A Backbone Edge Bridge Port that can receive and transmit
 I-tagged frames for multiple customers, and assign B-VIDs and translate I-SID on
 the basis of the received I-SID.
              
Edge Virtual Briding (EVB) technology is used in Data Center Networks. 
The uplinkAccessPort (UAP) and stationFacingBridgePort (SBP) types are 
applicable when the bridge operates in EVB environment.
              
uplinkAccessPort - A port on a Port-mapping S-VLAN component that
connects an EVB Bridge with an EVB Station.
              
stationFacingBridgePort - A port that is part of the C-VLAN component of 
EVB Bridge which has one-to-one relationship with a S-Channel Access Port
in the port-mapping S-VLAN component. 
              
In Customer bridges and in Provider Bridges only customerPort option
is allowed.
              
 In Provider backbone bridge only customerNetworkPort, providerNetworkPort
 and customerBackbonePort type of ports are allowed.
              
Bridge Port Type cannot be set for a port-channel port, if some 
physical ports are aggregated in it.
Also Bridge Port type cannot be set for a port, if part of a 
port-channel.
              
Whenever the Bridge port type changes, the previous configuration 
associated with the port will be flushed.
              
For example. 
              
whenever CNP(STagged) and PNP port types are changed to any 
other port type,
  - The unicast entries learnt on this port and 
  - The VID translation table entries associated with the port 
    will be flushed.
              
Whenever CEP port type is changed to any other port type,
  - The unicast entries learnt on this port
  - The C-VID registration table entries associated with the port
  - The PEP configuration table entries
  - The service priority regeneration table entries 
  will be flushed.
              
  Even the vlan membership of the port will be removed when the 
  Pbport type is changed.
