Vflpassociares (registers) a VSI intanee with aa Station-facing Bfldgc Pon tSBPlofan EVB Bridge. VDP simphlies and annotates virtual station configuration by enabling the movement of a VSI instance (and its nrlatcd VSI Type intomiatiun) lions osie sittual station to anuLlter 4% (roan tate LVII Bridge to another. \Lfl’ suppons VSI discovery and configursmon teresa a channel interconnecting an EVB station and an E%’B Bndgc VOP TLVa axe exchanged between the station and the Bridge in suplaid of Usia protocol.
This suhelause defines the Vl)l’TLV structure and slate machines.
When VLW is used between EVIl Station ansi lVll Itrsdirc. VIW uses ECP (Clause 43( as a transport protocol for VDP TIN exchanges. When ECP is used as a ranagon protocol for VDP. ECP uses the Nearest Cuomer Bridge iuoun MAC address TaMe St-fl as the destination address for ECPPUs. Three VDP rEVs are defined as follows:
a) The VSl manager Ii) TLV (41,1). There is a single instance of this TI.V in sty ECPDIJ that canes VDP. and it appears as the tint TIN in the ECPDU.
h) The VPP association TLV 141.2). One or more of these rEVs can appear in any ECPDU. following the VSI manager II) rEV.

Change 41.2.3 us follows:
The Staia field contains a 4-bit error type, encoded in bits 1-4. aid four individual Boolean flags. encoded in bits 3—8.
Foe all requests, rise error type field is reserved foe (attic staidardi.ratton; it is transmitted as Oat) and is ignored on rec’etpt.IEEE 802.1Qcy pdf download.
