IPMI Specification.2. User Configuration (Set by the command SetUserAccess).3. Total Session Slots. (Hard-coded in the FW).4. Per channel Session limit imposed. (Hardcoded in the FW Configuration).5. (Dynamically dependent on) FW resource constraints.For example, on Serial Channel the Maximum sessions per channel is limited by the IPMIspecification (=1). This value is hardcoded in the FW and maintained as a non-read/writeconfiguration parameter (bullet 4). Where the Maximum is not defined by the specification, thehard-coded per channel value is still maintained in the FW. For Instance, the hard-coded value(bullet 4) for each of the LAN channels is 15.But, ∑ (per channel session limit) (bullet 4) > (total session slots) (bullet 3); this is done so thatthe available slots can be used optimally. Even then, the user might not be able to open theMaximum # sessions per channel on a particular channel. The Maximum per channel sessionlimit is used only to maintain fairness in session usage across the Channels. TheGetSessionInfo() command will return the hard-coded (see bullet 3) value of the total MAXsession slots available.The SetUserAccess() Command can be used to limit the number of concurrent sessions openper user. This user configured value together with the internal hard-coded per channel sessionlimits (bullet 4) might sometimes not allow the usage of all session slots. Finally (bullet 5) furtherresource constraints might not allow the full utilization of the session slots, in those cases theFW might dynamically reduce the number of slots available.On Emerald Ridge platform, maximum no of IPMI over LAN sessions are configured as 16 (parLAN channel) and to ensure web server availability, 4 session slots are reserved for EmbeddedWeb Server. Total no of possible sessions at any point of time are 36.4.4 Media BridgingThe BMC supports bridging between the LAN and IPMB interfaces. This allows the state ofother intelligent controllers in the chassis to be queried by remote console software. Requestsmay be directed to controllers on the IPMB, but requests originating on the IPMB cannot bedirected to the LAN interface unless the request is originated by the ME on the secondary IPMB.Available bridging combinations:KCS to IPMB (Primary)KCS to IPMB (Secondary)LAN to IPMB (Primary)LAN to IPMB (Secondary)IPMB (Secondary) to LAN58Intel ConfidentialRevision 1.1
