	you may want to use a later version of Netscape when it becomes available.
Upgrade Link Window	Since Enterprise OS software version 11.4 Upgrade Link cannot resize the browser
Resizing	window, you should maximize the browser window so that all of the Upgrade Link
	dialog boxes are fully visible without scrolling.
IBM Protocols and	This section describes notes, cautions, and other considerations to be aware of
Services Notes	when using the Enterprise OS software when with IBM protocols and services. The
	topics are presented in alphabetical order.
APPN	In software version 11.4, APPN does not support SMDS.
APPN Connections to	When you connect to a 3174 on a token ring, you may need to enable transparent
3174 through	bridging on the bridge/router. The 3174 may send exchange identification (XID) as
Token Ring	a non-source routed frame.
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
	NETBuilder II port at the central site. An alternative work around is to configure
	APPN with DLSw at the central site and to use the CEC’s MAC address at the
	remote site.
APPN CP-CP Sessions on	When parallel transmission groups (TGs) are configured between 3Com network
Parallel TGs	nodes and both TGs support CP-CP sessions, a CP-CP session on one TG does not
	switch to the other TG if the user disables the port or path. This happens because
	both sides learn about the link failure at different times. The network node with
	the disabled port or path learns about the link failure right away and tries to bring
	CP-CP sessions up on the second TG. However, the second network node does
	not learn about the link failure until LLC2 times out; because it thinks the link is
	still up, the second network node does not allow CP-CP sessions to start on the
	second TG. After five attempts at bringing up CP-CP sessions on the second TG,
	the second TG will be flagged as not supporting CP-CP sessions, preventing CP-CP
	sessions from coming up on that second TG. To prevent this situation, manually
	stop the first TG by entering the SET -APPN LinkStaCONTrol <LinkName>
	Deactivate command before disabling the port/path. By doing this, both network
	nodes will learn that the link has gone down at the same time, and CP-CP session
	can be activated on the second TG.
APPN DLUr Connections	When you configure an APPN dependent LU requestor (DLUr) connection from a
to 3174 Systems	NETBuilder II bridge/router to a 3174 cluster controller, the NETBuilder II network
	node and the 3174 must be on the same ring. In this configuration, the
	NETBuilder II token ring port must be set to transparent bridging only.
BSC and Leased Lines	The BSC pass-through feature is limited to leased lines and cannot use dialup links.
