A bridging PVC is assigned a protocol value. This value must be consistent with the bridging method defined for the logical interface. Bridging PVCs are assigned either of the following protocol values:
1.proto=llc,bridging,xxxx
This type of PVC is used for logical interfaces defined with
bridge_method=llc_encapsulated, as well as logical interfaces not used for bridging. This PVC uses LLC encapsulation for each Protocol Data Unit (PDU).
xxxxrepresents a second protocol qualifier required for the proto= parameter.
This PVC entry enables bridging on an LLC PVC:
PVC ga030 0/32 proto=vcmux_bridge,bpdu \
traffic_shape=high_speed_high_quality
2.proto=vcmux_bridge,yyyy
This type of PVC is used only for logical interfaces defined with bridge_method=vc_multiplexed. The PVC carries bridged traffic of a single type.
yyyyrepresents a second protocol qualifier required for the proto= parameter. This qualifier defines the type of bridged traffic the PVC can carry. Traffic types include:
•proto=vcmux_bridge,ether_fcs
Each PDU is an Ethernet frame, including a Frame Check Sequence (fcs).
•proto=vcmux_bridge,ether_nofcs
Each PDU is an Ethernet frame, without fcs.
•proto=vcmux_bridge,fddi_fcs
Each PDU is an FDDI frame, including fcs.
•proto=vcmux_bridge,fddi_nofcs
Each PDU is an FDDI frame, without fcs.
•proto=vcmux_bridge,bpdu
Each PDU is an 802.1d Bridging Protocol Data Unit (BPDU).
