One comment that I should have made on your RFC is that I wonder if it is necessary to include the data analysis/reduction part. I think it is because there is too much data to push up the tree to one manager. I agree, but does the data need to be pushed to one node? If you go with a distributed approach where information is aggregated per network device (switch or group of switches), The proposal includes a distributed approach. then a third-party monitoring server can collect and present it in the same way that it does for an Ethernet network. That way, you do not need to pass information up to a central node. You can just have a third party monitoring application collect and present the information. I guess it just depends on how much you want to leverage existing monitoring solutions and/or how much capability you want inherent in the OFA software. Third party monitoring agents can hook in at the intermediate nodes in the collection hierarchy if that is what is desired. Just having a central location that collects the values and presents it via SNMP is extremely useful since there are a plethora of monitoring apps (free and commercial) that do what you are proposing. I should have said 'a location' and not 'a central location'. Since most monitoring applications support multiple agents, it is not necessary to aggregate the information into one place. In general, this information can be exported via SNMP or whatever the management infrastructure is. BTW, are there SNMP MIBs for all of this information ? To my knowledge, some of these were started but never completed. Also, the MIBs were geared at the agents rather than the managers (in the PerfMgt arena). There are standard MIBS (e.g. mib-2's ifTable) that can present most of the useful information (in/out octets, errors, etc.) Not most of the useful IB information. , but I would suspect that you would have to supplement that with a private MIB as most other technologies/vendors have. Yes, as this may be data out of a non IBTA specified manager, it is likely a private MIB unless one goes for all the agent (PMA) data. There was a proposed MIB for the PMA at the IETF IPoIB WG. -- Hal Steven. -- Hal That way, a network manager can leverage existing tools currently used for monitoring Ethernet Nodes, Hosts, etc. You can still include a last change attribute with each counter so that simple utilities (like the one that I am writing) can get an idea of how quickly errors are occurring.
