Known Problems 39

LAN Network Manager

If you have previously configured your LAN Network Manager to use the

with NETBuilder II

NETBuilder II system as a virtual ring, and you want to use it as a physical ring, you

Systems

must set your virtual ring number back to None.

LLC2 Frames and PPP

LLC2 frames are not sent or received over PPP unless global bridging is enabled

 

using the SETDefault -BRidge CONTrol = Enabled command. You must enable

 

LLC2 on the port using:

 

SETDefault !<port> -LLC2 CONTrol = Enabled.

 

If bridging is enabled and you do not want bridging, either set the -BRidge

 

CONTrol parameter to NoForward, or disable bridging on individual ports by

 

setting the following command:

 

SETDefault -BRidge TransparentBridge = NoTransparentBridge

Remote Access

To increase network security, the default value for the NetAccess parameter in the

Default Change

SYS Service is set to NoRemote. This means that by default, no remote connection

 

attempts will be accepted by the bridge/router. If you are accustomed to or want

 

to use remote access, you must specifically set the value of the NetAccess

 

parameter to Remote.

SuperStack II and

For SuperStack II and OfficeConnect NETBuilder bridge/routers, flash memory is

OfficeConnect Boot Path

the only storage media, which is not designated with a drive letter. When entering

 

the boot path, do not specify a drive letter. Specifying a drive letter causes the

 

boot load to fail.

V.25bis Modem Setup

If you are using a V.25bis modem with a NETBuilder boundary routing leaf node,

 

and you configure the line type explicitly as dial rather than auto, be certain to also

 

set the DialMode to V.25bis rather than use the default of DTR.

Web Link

When you set the DocumentPath parameter in the WebLink service to a local file,

Documentation Path

drive C for example (“file:///c:”), the Web Link assumes that access to the

 

NETBuilder bridge/router takes place only from the computer to which the file is

 

local. If Web Link is used from any other computer, the browser looks on its local

 

“C” drive for the help pages. If the computer is a UNIX machine and these files are

 

not present as expected, unpredictable browser behavior will result.

Zmodem Time Out

A Zmodem file transfer from a PC to a SuperStack II or OfficeConnect

 

bridge/router can take a long time. To minimize the possibility that the PC

 

Zmodem software will time out during the download, run the DEFRag command

 

on the SuperStack II bridge/router before beginning the file transfer. The DEFRag

 

command reclaims dirty space in flash memory. Dirty space is memory that has

 

been written on and cannot be used again until it has been erased.

This section describes known problems in software version 11.1. Topics are in

 

alphabetical order.

APPN CP-CP Sessions

If you set up APPN routing in an SNA Boundary Routing configuration from a

and SNA Boundary

NETBuilder II bridge/router to a leaf node bridge/router, CP-CP sessions between

Routing

the remote site PC and the NETBuilder II bridge/router are established before you

 

can configure the Boundary Routing configuration on the NETBuilder II

 

bridge/router. However, after you set the -BCN CONTrol parameter for IBM traffic

 

and enable the -BCN Service, the NETBuilder II bridge/router no longer receives the

 

CP-CP sessions. To work around this problem, first turn off BOOTP on the
