Fibre Channel MIBs Keith McCloghrie 9 Nov 2004
A Brief History • RFC2837 = first standardized MIB for FC • Fibre Alliance MIB submitted to IETF • lots of implementations, but • too many changes to be acceptable • T11 has published MIB-FA as informational • IPStorage WG defined FC-MGMT-MIB • merging of 2837 & MIB-FA • lots of FC functionality not covered • proposal to define additional MIBs
Brief History (ctd) • The proposal listed 9 additional MIBs • After some discussion, process is: • the technical MIB definitions will be submitted first to T11 (T11.5 Management Ad Hoc) • T11 will review/update/edit to ensure conformance with FC standards; then pass to IMSS WG of IETF • IETF will ensure conformance to SMIv2 and consistency with other MIBs • when both organizations are happy, publish as RFC.
Current Status • T11 have now passed the first two MIBs to the IETF: • Fabric Address Manager MIB • draft-ietf-imss-fc-fam-mib-00.txt • Name Server MIB • draft-ietf-imss-fc-nsm-mib-00.txt • T11 beginning work on the next two: • FC Routing • FSPF
draft-ietf-imss-fc-fam-mib-00.txt • Contains two MIB modules: • T11-TC-MIB • FabricIndex is only TC defined (so far): • to support multiple Virtual Fabrics (new in FC-SW-4) • T11-FC-FABRIC-ADDR-MGR-MIB • management of FC address assignment: • Domain_IDs & FC_IDs • all tables are INDEX-ed by: • FC Management Instance Index (from FC-MGMT-MIB), • Switch Index (from FC-MGMT-MIB) • Fabric Index
FAM MIB (ctd) • Five tables containing address-related information: • per-Fabric parameters/status/statistics • per-interface configuration/status • per-Area Port_ID assignments • per-Domain assignments (to switches) • cache of released assignments • Three notifications • assignment failed; new principal switch; BF/RCF
draft-ietf-imss-fc-nsm-mib-00.txt • Contains one MIB module: • T11-FC-NAME-SERVER-MIB • management of information registered with the Name Server • T11 had much discussion about the INDEX-ing • FC’s Name Server is defined as a distributed function • eventually agreement to focus on subsets of the registered information, (not on where or how it’s implemented) • each subset can be the information known/registered: • at a switch or • at a central location, or • anywhere else within the Fabric !
NSM-MIB (ctd) • All tables are INDEX-ed by: • Management Instance (from FC-MGMT-MIB), • Subset Index • Five tables: • per-subset information (various) • info registered about a port (in a Fabric) • the one or more FC-4 types registered for a port • per-Fabric stats • per-port log of most-recently rejected registration • One notification: on a rejected registration • binary content of registration request, and • error codes
