5. Conformance
5.4 VLAN Bridge component requirements
5.4.1 VLAN Bridge component options
Insert new subelause 54.1.8 as shown, renumbering as necessary:
5.4.1.8 Per-stream ftring and plcing (PSFP) requirements
A VLAN Bridge component implementatio that conforms 1o the prvisions of this standard for PSFP sall:
a Support PSPP as spciied in 8.6.5.1 and 8.66.1.
b) Support the state machines for stream gate control 2 specified in 8.6.10.
c) Support the mangement entties for PSFP as specifed in 12.31.
5.13 MAC Bridge component requirements
5.13.1 MAC Bridge component options
Insert new subclause 5.13.1.1 a shown, reumbering as ecessary:
5.13.1.1 Per-stream fitering and policing (PSFP) requirements
A MAC Bridge component implementatio thut conforms to the provisions of this sandard for PSFP sall
a) Support PSPP as spcied in 8.65.1 and 8.661.
b) Support the state machines for stream gate conirol s spcied in 8.6.10.
c) Support the management entties for PSFP as specified in 1231.
Insert the flowiw new gnwbclouse at the end of Cluse s rerumbering as nessar:
5.27 End-station requirements- PSFP
An end-station implementatio thatl conforms 10 the provisions of this standard for PSFP shal:
a) Support PSFP as spcified in 8.6.5.1 and 8.66.1.
b) Support the state machines for stream gate control as specified in 8.6.10.
c) Support the mangement enities for PSFP as specifed in 12.31.
8. Principles of bridge operation
8.6 The Forwarding Process
Replace Figure 8-11 with the following figure. The effect of this replacement is to change“Ingress (8.6.2)”to “Ingress filtering (8.6.2)”and “Egress (8.6.4)” 10 “Egress filtering (8.6.4)” to match the subelause headings.
8.6.5 Flow classification and metering
Insert new list item e) immediately following list item d), and change the sentence immediately following new item e), renumbering following list items, as shown:
e) connection. jidentifier
Item c), specifying a VID value, is not applicable to VLAN-unaware MAC Relays. Item e), specifying a connection_ identifier, is only applicable to bridges that support PSFP
Insert new subclause 8.6.5.1, Figure 8-12, and Table 8-5 as shown, renumbering subsequent figures and tables as necessary:
8.6.5.1 Per-stream filtering and policing
A Bridge or an end station may support PSFP capabilities that allow filtering and policing decisions, and subsequent frame queuing decisions (8.6.6.1), to be made on a per-stream basis for received frames.
Support of PSFP requires implementation of the Stream identification function specified in Clause 6 of IEEE Std 802.1CB, as the stream. handle provided by this function is used in the policing and queuing decisions taken by PSFP. IEEE Std 802.1 pdf download.
