Managing Local Area Networks  

• Local Area Network Control Program (LANCP)



• LAN Auxiliary Control Program (LANACP) LAN server process

LAN system management tools:

• Allow you to set LAN parameters to customize your LAN environment.



• Display LAN settings and counters.



• Provide Maintenance Operations Protocol (MOP) downline load support for devices such as terminal servers, x-terminals, and LAN-based printers, and for booting satellites in an OpenVMS Cluster environment.



• Provide MOP console carrier and MOP trigger boot support.

LAN System Management Enhancements describes the LAN management software and the functionality supported on systems running OpenVMS Alpha, OpenVMS VAX, and OpenVMS I64.

Table 2   LAN System Management Enhancements

Utility	Description	OpenVMS Support
LAN Auxiliary Control Program (LANACP)	Runs as a server process whose primary function is to provide MOP downline load service. Other services include maintenance of a LAN volatile device database and a LAN volatile node database.	The LANACP utility provides comparable functionality on VAX and Alpha systems running OpenVMS Version 7.0 and later, and I64 systems running OpenVMS Version 8.2 and later.
LAN Control Program (LANCP)	Allows you to control LAN software parameters and obtain information from the LAN software. You can use the LANCP utility to: Obtain LAN device counters, revision, and configuration information Change the operational parameters of LAN devices on the system Maintain the permanent and volatile LAN device and node databases Control the LANACP LAN server process (including MOP downline load server related functions) Initiate MOP console carrier connections Send MOP trigger boot requests to other nodes	OpenVMS Alpha Version 6.1 contained the initial implementation of LANCP, which did not include MOP-related functions. OpenVMS Version 6.2 (VAX and Alpha) added MOP-related functions and extended some of this capability to VAX systems. The following table shows how the LAN utility functions are currently supported on VAX, Alpha, and I64 systems: OpenVMS Alpha Version 7.3-1 and later  Change operational parameters of LAN devices?   Yes Display LAN device information?   Yes Support MOP functions?   Yes OpenVMS VAX Version 7.3 and later  Change operational parameters of LAN devices?   No Display LAN device information?   Limited Support MOP functions?   Yes OpenVMS I64 Version 8.2 and later  Change operational parameters of LAN devices?   Yes Display LAN device information?   Yes Support MOP functions?   Yes
