if Main Brg Port Type

1.3.6.1.4.1.207.1.4.167.27.1.4.1.7

The Bridge port type of this specified externally accessible port. Bridge Port type can be specified only for switch ports and not for router ports. 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. Accsystable 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, recsystion 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. In Customer bridges and in Provider Bridges only customerPort option is 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.
