1 FC-BB-6: New FCoE Functionality David Peterson Brocade Communications, Inc.

2 FC-BB-6 Project proposal scope Support for VN_Port to VN_Port virtual links Investigate improvements in support for high BER Ethernet transmission media (e.g.,10gbase-t) Any other item(s) deemed necessary during the development of the standard 2

3 FC-BB-6 What s Gone? SPMA Informative annex for pre-fip Virtual Link instantiation 3

4 FC-BB-6 What s New? (at this point ) VN_Port to VN_Port (VN2VN) Data path enhancement(s) Single Domain_ID FCoE Fabric 4

5 FC-BB-6 Current status VN_Port to VN_Port complete Much discussion (continues) on data path functionality Short-cut routing Single Domain functionality is basically agreed upon other than routing capability within the Single Domain, but much work remains 5

6 FC-BB-6: VN_Port to VN_Port VN_Port to VN_Port (VN2VN) Point-to-Point (P2P) Point-to-Multi-Point (P2MP) Equivalent to FC Arbitrated Loop Intended for isolated/dedicated networks Limited number of ENode(s) 6

7 FC-BB-6: VN_Port to VN_Port Point-to-Point (P2P) Point-to-Multi-Point (P2MP) 7

8 FC-BB-6: VN_Port to VN_Port VN2VN_Port(s) FPMA (VN2VN-FC-MAP Locally Unique N_Port_ID) VN2VN-FC-MAP = 0EFD00h Locally Unique N_Port_ID(s) are generated in the range h to 00FFFEh Generation algorithm based on RFC 3927 (Dynamic Configuration of IPv4 Link-Local Addresses) 8

9 FC-BB-6: VN_Port to VN_Port P2P and P2MP Protocol If an FCF is detected and the VN2VN ENode MAC is configured to operate in P2P mode, the ENode MAC operates in Fabric mode and P2P protocol stops If an FCF is detected and the VN2VN ENode MAC is configured to operate in P2MP mode, the ENode MAC may operate in Fabric mode or in concurrent mode (i.e., VN_Port and VN2VN_Port) 9

10 FC-BB-6: VN_Port to VN_Port VN_Port to VN_Port Reference Model 10

11 FC-BB-6: VN_Port to VN_Port VN_Port to VN_Port Reference Model 11

12 FC-BB-6: VN_Port to VN_Port ENode Requirements Must support VN2VF and VN2VN Virtual Links Any instance of a VN_Port operates as either a VN2VF_Port or VN2VN_Port (i.e., not both) There is no communication between a VN2VN_Port and VN2VF_Port VN2VN_Ports are not present in the VN2VF_Port topology VN2VF_Ports are not present in the VN2VN_Port topology Must support one or more VN2VN_Port(s) via a single ENode MAC 12

13 FC-BB-6: VN_Port to VN_Port VN_Port Requirements Single VN2VN_Port and FCoE_LEP in P2P Multiple VN2VN_Port(s) in P2MP Each VN2VN_Port instance has one or more FCoE_LEPs 13

14 FC-BB-6: VN_Port to VN_Port ENode Functional Model(s) FC-3/FC-4s FC-3/FC-4s FC-3/FC-4s FC-BB-5 VN2VF Model (additional MAC(s) not shown) FC-BB-6 VN2VN Model VN_Port FC-2V...

15 FC-BB-6: VN_Port to VN_Port 15

16 FC-BB-6: VN_Port to VN_Port P2P Example - 2 ENode(s) with single VN2VN_Port at each ENode 16

17 FC-BB-6: VN_Port to VN_Port P2MP Example - 3 ENode(s) 17

18 FC-BB-6: VN_Port to VN_Port P2MP Example - 3 ENode(s) 18
