LAN Server Subsystem

What is It?	The LAN Server Subsystem (LSS) software lets PathBuilder S200 series switches
	such as the PathBuilder S200 series switch communicate with an IBM LAN
	Manager to provide the following support for Token Ring Source Route Bridging
	applications:
	• Ring Error Monitor (REM)
	• Configuration Report Server (CRS)
	• Ring Parameter Server (RPS)
	• LAN Bridge Server
What You Need to
	The LAN Server Subsystem (LSS) Record is configured for the Token Ring/Source
Configure	Route Bridging LAN port. A Node boot is required to restart the LSS or implement
	LSS parameter changes.
Passwords
	The default LSS link passwords for links 0 through 3 are initially set to
	“PASSWORD.” This password is used by the IBM LAN Network Manager to
	establish a connection to the 3Com bridge’s LSS. Default passwords can be changed
	by the LAN Manager. There is no facility to examine or change the passwords from
	the bridge’s human interface.
	Also, it is recommended that you leave the parameter Calculation Interval at the
	default setting of 10 seconds to avoid conflict with the LNM.
Ring Error Monitor
	A REM observes, collects, and analyzes hard error and soft error reports sent by
	stations on a single ring and assists in fault isolation and correction.
	One or more ring error monitors can reside on a ring. If no REMs are on a particular
	ring, it is not possible to monitor errors for that ring.
	One or more REMs can report to a LAN manager.
	A REM has a functional address of C000000008.
Configuration
	A CRS accepts commands from the LAN Manager to get station information, set
Report Server	station parameters, and remove stations from its ring. It also collects and forwards
	configuration reports generated by stations on its ring to the LAN manager.
	Information such as reporting a new active monitor and reporting a stored upstream
	address change are sent to the CRS.
	A configuration report server has a functional address of C00000000010.
Ring Parameter
	An RPS resides on each ring in a multiple-ring environment for which operational
Server	parameters are being managed, and provides three main services:
	• Sends initialization information to new stations that are attaching to the ring.
	• Ensures that stations on the ring have consistent values for operational
	parameters.
	• Forwards registration information to LAN managers from stations attaching
	to the ring.
