Updates to this registry are coordinated with the designated expert. Donald Eastlake (primary), Sue Hares (secondary) This registry provides centralized documentation of Ethertypes that were assigned by the IEEE for initial use with TRILL. In some cases, particularly L2-IS-IS and MT, they may be used with other protocols. 0x22F3 TRILL TRILL data 0x22F4 L2-IS-IS IS-IS 0x893B FGL Fine Grained Labeling 0x8946 - TRILL RBridge Channel 0x9A22 MT Multi-Topology IETF Review 0-2 Critical Summary Bits 3-6 available critical hop-by-hop flags 7 Critical Channel Alert Flag 8 Non-critical Channel Alert Flag 9-11 available non-critical hop-by-hop flags 12-13 TRILL-ECN (Explicit Congestion Notification) 14-16 Extended Hop Count 17-20 available non-critical reserved flags 21-25 available critical ingress-to-egress flags 26 Critical Congestion Experienced (CCE) 27-28 Extended Color 29-31 available non-critical ingress-to-egress flags 0x002-0x0FF Standards Action 0x100-0xFF7 RFC Required allocation of a single value 0x100-0xFF7 IESG Approval allocation of multiple values 0x000 Reserved 0x001 RBridge Channel Error 0x002 BFD Control 0x003 BFD Echo 0x004 RBridge Channel Extension 0x005 Pull Directory Services 0x006 Port-Shutdown 0x007 P2MP BFD Control 0x008 Vendor-Specific RBridge Channel 0x009 Address Flush 0x00A-0xFF7 Unassigned 0xFF8-0xFFE Reserved for Private Use 0xFFF Reserved IETF Review 0 Reserved 1 Blocks of VLANs 2 Bit Map of VLANs 3 Blocks of FGLs 4 List of FGLs 5 Bit Map of FGLs 6 All Data Labels 7 MAC Address List 8 MAC Address Blocks 9-254 Unassigned 255 Reserved IETF Review 0 Reserved 1 Null RFC7978, Section 3.1 2 Ethertyped Payload RFC7978, Section 3.2 3 Ethernet Frame RFC7978, Section 3.3 4-14 Unassigned 15 Reserved IETF Review 0 None RFC7978, Section 4.2 1 IS-IS CRYPTO_AUTH-Based Authentication RFC7978, Section 4.3 2 DTLS Pairwise Security RFC7978, Section 4.4 3 Composite Security RFC7978, Section 4.5 4-14 Unassigned 15 Reserved IETF Review 0 SL Silent 1 MH Multi-hop 2 NA Native 3-11 Unassigned Standards Action Value 15 is intended to be allocated by Standards Action for an error code expansion feature when it appears likely that all other available error codes are being allocated. 0 No error 1 Frame too short (truncated Ethertype or Channel Header) 2 Unrecognized Ethertype 3 Unimplemented value of CHV 4 Wrong value of NA flag 5 Channel Protocol is reserved or unimplemented 6 Unknown or unsupported field value 7 Authentication failure 8 Error in nested RBridge Channel message 9-14 Unassigned 15 Reserved (see Note) IETF Review 0 No Error, suberrors not allowed 1-5 (no suberrors assigned) 6 0 Reserved 6 1 Non-zero RESV4 nibble 6 2 Unsupported SType 6 3 Unsupported PType 6 4 Unknown Key ID 6 5 Unsupported Ethertype with PType = 2 6 6 Unsupported authentication algorithm for SType = 1 6 7 Non-zero SubERR with zero ERR field 6 8-15 Unassigned 7-14 (no suberrors assigned) 15 Reserved Standards Action 0x00 No error 0x01 Message too short 0x02 Unknown OUI/CID 0x03 Unknown Sub-Protocol 0x04 Unknown Sub-Version 0x05-0x0F Unassigned 0x10-0xFE Reserved for vendor use 0xFF Reserved IETF Review 0 Affinity sub-TLV support 1 FGL-safe 2 OAM capable 3 Backwards-compatible OAM 4 E-L1FS FS-LSP support 5 Able to handle the NickBlockFlags APPsub-TLV 6-13 Unassigned 14 Extended Hop Count support 15-16 Unassigned 17-20 available non-critical reserved flags 21-26 available critical ingress-to-egress flags 27-28 Extended Color support 29-31 Extended header flag support IETF Review 0 Hello reduction support. 1-2 Unassigned 3-13 Hop-by-hop extended flag support. 14-15 Topology labeling support. 16-31 Unassigned Standards Action 0 Fail Failed MTU test 1 OOMF Offering OOMF service 2-7 Unassigned IETF Review These bits appear in the Interested VLANs record within the Interested VLANs and Spanning Tree Roots Sub-TLV (INT-VLAN) specified in . 0 M4 IPv4 Multicast Router Attached 1 M6 IPv6 Multicast Router Attached 2 Unassigned 3 ES ESADI Participation 4-15 (used for a VLAN ID) 16 AA VLANs for Active-Active 17 Unassigned 18 PUL Pull Directory 19 NOD No Data 20-31 (used for a VLAN ID) IETF Review These bits appear in the Interested Labels record within the Interested Labels and Spanning Tree Roots Sub-TLV (INT-LABEL) specified in . 0 M4 IPv4 Multicast Router Attached 1 M6 IPv6 Multicast Router Attached 2 BM Bit Map 3 ES ESADI Participation 4 AA FGLs for Active-Active 5 Unassigned 6 PUL Pull Directory 7 NOD No Data IETF Review with additional requirements on the documentation of the use being registered as specified in Section 7.2 of .
