Bridging
LAN Server Subsystem
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 
Configure 
The LAN Server Subsystem (LSS) Record is configured for the Token Ring/Source 
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 
Report Server
A CRS accepts commands from the LAN Manager to get station information, set 
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 
Server
An RPS resides on each ring in a multiple-ring environment for which operational 
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.
