LANVCP Operation
LAN Virtual Control Panel (LANVCP) server software for downloading systems or controlling •front panel" operations of a remote node is provided with VC+ (HP 92078A). For a given LANIC card, the LANVCP server software and the Node Manager software receive packets through the same •channel", which is governed by the design of the driver and other software. An intermediate program, DISPATCH, is provided to inspect and properly route incoming packets to the appropriate program or software module. DISPATCH must be used when both the Node Manager and other LANVCP software access the same LANIC card.
The server software required for LANVCP operation are the following modules: DISPATCH, RMVCP, VCPMT, IPL_BUILD and IPL_EDIT. These modules are shipped in the /VCPLUS/LANVCP directory. LANVCP operation and these required modules are described in more detail in Chapter 6.
Node Manager Software Services
The Node Manager software provides four primary categories of services: Configuration, Statistics, Diagnostics and Event Logging. Since Node Manager software at one node can •talk to" Node Manager software at another node, these services may be accessed locally or remotely. This is illustrated in Figure 1"3.
