	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.
Known Problems	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
