MIB Stataus: Not updated There is an Open IB group, to implement IB on 2.6 Linux. Bill presents Hal's slides. January 2004 there was a IBTA Plugfest to test interopbility. August will be another plugfest. Organized by IBTA and OpenIB is participating that. January/Feb 2005 again. Need to resolve NDA issue with IBTA and IETF. Margeret will work with Bill on that. check openib.org for update. Issues: ARP size is too small for IB. Rebuild kernel to make room for it. Simply enlarge that will that break IO control, may cause problem with user program? IB uses MC to implement Broadcast. What does "JOIN" MC mean? Does Join mean create? IBTA doesn't have a position on that. Should we tighten this saying purposely left-out? Also QKey generation need to be resolved. Need to look at spec to find QKey conflict. How to define IPOIB interface RUNNING? When? before or after join the BC/MC? SM Restart losing multicast subscription. IBTA will stress that SM should maintain the info. Performance: Max UD is max 4K but currently 2K. Vivek: status of the drafts. 3 drafts are being published. Architecture. DHCP has been through lastcall, to send note to DHCP group to review it. transmission over ip, has been through last call. GID format (bit reversed?)has some problem, need to fixed in IB spec. Vivek: IPoIB Connected Mode. IPOIB modes. advantage: Large MTU for better throughput. Topic, How to do address resolution in multicast? rely on UD QPKey to solve multicast problem. Suggested use UD QPN to create a service ID. MTU negotiation between min,desired, accepted MTUs. on going discussion: multiple connections allowed or not? one comment: should this be a configuration parameter? Vivek - Chang - IB Subnet manager MIB status Goal is to enable out-of-band configuration of IB Subnet Manager and IB fabrics and monitoring of IB fabrics. Multicast - suggestion that Multicast table be Read-Write with minimum access of Read. Then it could start out as read only and later if Writes could be allowed without having to introduce a new object. Chang points out that the object might not be the ideal object form for doing that anyway. Issue left open for discussion. Trace record - suggested that the author also look at the DisMan draft. Notification - why not just use a normal notification macro instead of encapsulating? Wouldn't it be more useful for network managers to use notifications that it can understand. Answer, encapsulation uses the Infiniband notifications. In the current notification, some identifying information such as node number are in the format. This seems sufficient.
