3Com 11.1 Notes and Cautions

34 NETBUILDER SOFTWARE VERSION 11.1 RELEASE NOTES

UpgradeLink -NA

Otherwise, an error dialog box is returned with the message “Could not verify

user.”

If you use tftp, the “Verify Upgrade Services” step does not need the user or

password to be veriﬁed, so those entries as well as the FTP Client User Name and

Password, should be ignored.

Upgrade Link and

Netscape Browser Scroll

Bars

Netscape version 4.05 with AWT patch 1.1.5 has the Java support required by

NETBuilder software version 11.1 Upgrade Link. Certain problems have been

found with this Netscape patch release, such as sometimes the Netscape browser

fails to add scroll bars with text ﬁelds. If you experience this or other problems, you

may want to use a later version of Netscape when it becomes available.

Upgrade Link Window

Resizing Since NETBuilder software version 11.1 Upgrade Link cannot resize the browser

window, you should maximize the browser window so that all of the Upgrade link

dialog boxes will be fully visible without scrolling.

Notes and Cautions This section describes notes, cautions, and other considerations to be aware of

when using the NETBuilder bridge/router software. The topics are presented in

alphabetical order.

APPN Connections to

3174 through

Token Ring

When you connect to a 3174 on a token ring, you may need to enable transparent

bridging on the bridge/router. The 3174 may send exchange identiﬁcation (XID) as

a non-source routed frame.

Asynch Tunnelling on

Serial Ports For best results, set the LineType parameter to Leased and set the SuperStack II

NETBuilder bridge/router model 32x connector type for the universal port to

RS-232. For the path to come up, the bridge/router must see a DTR or DSR control

signal from the device. Or, if the device does not generate a control signal, a

loopback connector should be used to supply the control signal.

ATM LAN Emulation

Clients and Large 802.3

Frames

This release of LAN emulation software does not support large 802.3 frame

encapsulation as speciﬁed in the LANE standard 1.0. When IP routing is used from

FDDI to an emulated LAN, packets larger than 1500 are sent fragmented per IP

fragmentation rules.

Automatic Line

Detection When set to the value of Auto, the -PATH LineType parameter ﬁrst attempts to

bring up the path as a leased line by raising the data terminal ready (DTR) signal. If

the path comes up but a DTR-base dial modem is attached to the path, the

modem does not hang up until brought down manually with the HangUp

command. To avoid this situation, set the -PATH LineType parameter to Dialup.

Bandwidth-on-

Demand Timer

Precedence

Two PORT Service parameters are used to conﬁgure bandwidth-on-demand ports.

The DialIdleTime parameter sets the time in seconds before all dialup lines in a port

are disconnected if the port is not in use. The DialSamplPeriod parameter sets the

time (in seconds) to sample before taking an action to bring additional paths up or

down, based on trafﬁc load for bandwidth-on-demand. The value speciﬁed for the

DialIdleTime parameter takes precedence over the value speciﬁed for the

DialSamplPeriod parameter.
