Software Updates Are Free!
Hewlett-Packard provides free software updates on the HP ProCurve website. To
automatically receive email notice of new updates for all managed ProCurve and
AdvanceStack networking products, just fill out and mail the postage-paid card
attached to the TopTools CD sleeve included with your switch. Look for the CD
sleeve with Your Free Ticket to Proactive Networking on the cover. (If you have
already mailed one of these cards for another HP networking product, it is not
necessary to send in the card again.)
To determine whether you have the latest software, and to access software updates on the web, go
to the ProCurve website at http://www.hp.com/go/procurve, then click on Support and look for the link
to use for accessing and downloading software.
To Verify the Current Software Version in Your Switch. The switch displays its current soft-
ware version as a Firmware revision number. (For example, Firmware revision C.07.01.) Use any of
the following to view this number:
■Start a Console session. In the Console login screen (the first screen displayed), the Firmware
revision line under the switch name shows the software version.
■If you are already displaying a Console menu, go to the Console Main menu and select
1. Status and Counters
1. General System Information
In the resulting display, the current software version is listed as the Firmware revision number.
■In the web browser interface, click on the Identity tab. The current software version is listed
as the revision number in the Version line.

Your Free Ticket to Proactive Networking!
HP TopTools for Hubs & Switches is a breakthrough in network management software that gives you
more network with less work. The TopTools for Hubs & Switches CD is included at no extra charge
with your HP ProCurve Switch 8000M and 1600M. See the system requirements printed on the sleeve
containing the HP TopTools CD.
If You Receive a Disk with an HP ProCurve Switch Module
Switch modules introduced after the initial introduction of a switch chassis usually require a later
version of software than the original software version introduced with the switch. For this reason, a
disk containing the minimum switch software version required for the module is included with the
module. However, because HP periodically releases switch software updates that you may have
downloaded, your switch may already have either the same or a more recent version of the software
than the version on the disk that accompanied a module. For this reason, check the software version
currently in the switch before downloading software from a disk. (See ‘‘To Verify the Current Software
Version in Your Switch’’ on page 1.) If the software version in your switch is earlier than the version
on the disk, then you should download the disk version. But if the software version in your switch is
later than the disk version (for example, if software version C.07.01 is in the switch and version
C.06.01 is on the disk), then you can discard the disk.
Errata and Updates for the HP ProCurve Switches 1600M and 8000M Management
and Configuration Guide
Page 3-2; Web Browser Interface Requirements. To avoid possible problems with Java applets
in the switch’s web browser interface, HP recommends the following web browser releases:
Page 4-14; Rebooting To Activate Configuration Changes. Add “VLAN names” to the bulleted
list at the top of the page.
Page 6-5; Management Server URL. Under the “Management Server URL” heading, replace the
first sentence with the following:
“This field specifies which of the following two locations the switch will use to find online Help for
the web browser interface:
■The URL of the online Help provided by HP on the World Wide Web
■The URL of a network management station running HP TopTools for Hubs & Switches”
PCs:
• Netscape® Communicator 4.03
• Microsoft® Internet Explorer 4.01, SP1
UNIX:
• Netscape Navigator 4.03

Page 6-38; Spanning Tree Protocol (STP) Fast Mode. STP convergence time can take up to 30
seconds. During this time, end nodes that detect a network connection and are configured to
automatically try to access a network server may fail to establish a server connection. (This can occur
if server access is attempted while the switch port is negotiating its STP state.) To support end nodes
attempting this automatic access, the switch offers a Fast mode configuration option that causes the
switch port to skip the standard STP startup sequence and put the port directly into the ‘‘Forwarding’’
state, thus allowing the server access request to be forwarded when the end node needs it.
Caution
Fast mode should be used only on switch ports connected to end nodes. Using Fast on ports
connected to hubs, other switches, or routers may cause loops in your network that STP may
not be able to immediately detect. (However, after the Fast startup sequence, the switch
ports operate according to the STP standard, and will adjust their state to eliminate any
continuing network loops.)

Page 6-39; Modified Example Using a Trunked Link with STP and VLANs. The following
illustration more clearly shows the trunked link configured with two tagged VLANs.
Example of Using a Trunked Link with STP and VLANs
Page 6-43; Multicast Filters.
■Insert the following after the ‘‘Multicast Filters’’ heading: ‘‘Multicast filters are configured
using the Ethernet format for the multicast address.’’
■In the Note at the bottom of the page, insert the following at the end of the first sentence:
‘‘...(which corresponds to the Ethernet multicast address range of 01005e-000000 through
01005e-7fffff).’’
Page 6-44; Protocol Filter Type. In the bulleted list of filtered protocol types, change NetBIOS to
NetBEUI.
Problem:STPenabledwith
2 separate (non-trunked)
links blocks a VLAN link.
Solution:STPenabled with
1 trunked link.
Nodes 1 and 2 cannot
communicate because
STP is blocking the link.
Nodes 1 and 2 can
communicate because
STP sees the trunk as a
single link and 802.1Q
(tagged) VLANs enable the
use of one(trunked) link for
both VLANs.
802.1Q VLAN tagging
allows two or more
VLANs to use the
same link.

Pages 6-59 and 6-60; Errors in Port References for VLAN Example.
Page 6-59:
■Figure 6-38 contains port reference errors for “Switch Y”. The correct version is:
Figure 6-38. Example of Networked 802.1Q-Compliant Devices with Multiple VLANs on Some Ports
■In the paragraph following Figure 6-38, change “Port X-a...” to “Port X1...” Also, change the
last sentence to read “The same applies to ports X2, Y1, and Y5.”
Page 6-60:
■In the “Note”, change “...ports X-A and Y-E...” to “...Ports X2 and Y5...”
■In the sentence at the bottom of the table, change “...ports A1 and B5...” to “...X2 and Y5...”
■In the paragraph under “Spanning Tree Protocol Operation with VLANS”, change the last
two sentences (corrections underlined):
“However, you can use port trunking to prevent STP from unnecessarily blocking ports (and to
improve overall network performance). Refer to’Spanning Tree Operation with 802.1Q VLANs’
on page 6-38.”
Page 6-72; FEC (Fast EtherChannel®) Operation. FEC operates between paired devices
connected by a trunked link. A topology combining three devices in the same FEC link will not operate
properly. For example:

Page 6-94; Reserved Addresses Excluded from IP Multicast (IGMP) Filtering. Traffic to IP
multicast groups in the IP address range of 224.0.0.0 to 224.0.0.255 will always be flooded because
addresses in this range are ‘‘well-known’’ or ‘‘reserved’’ addresses. Thus, if IP Multicast is enabled
and there is an IP multicast group within the reserved address range, traffic to that group will be
flooded instead of filtered by the switch.
Page 6-100; Automatic Broadcast Control (ABC). In order for ABC to operate, the switch must
be configured with a valid IP address.
Page 8-3; Telnet (or Web Browser Interface) Access Problem. If one or more IP authorized
managers are configured, the switch allows inbound Telnet (or web browser interface) access only
to a device having an authorized IP address. For more information on IP authorized managers, see
the Software Update C.7.XX Release Notes for the HP ProCurve Switch 1600M, 2424M, 4000M, and
8000M, shipped with the switch (beginning in the 2nd quarter of 1999) and also available in the
Support area of HP’s ProCurve website at http://www.hp.com/go/procurve.
Page 8-11; Troubleshooting: Changed Event Type in Console Event Log and More
Information in Event Log Help Screen. In the table at the top of the page, replace the fault event
type with the FFI (Find, Fix, and Inform) event type. FFI event types are available in both the console
Event Log and the web browser interface Alert Log. Also, additional Help information for FFI events
has been added to the Event Log Help in the switch console.
Intrusion Log Notation. If you reboot the switch or display the Intrusion Log and reset the alert
flags, the log will list the time and date of all intrusions present at the time of the reboot or reset as
‘‘prior to’’ that time. For example, if the Intrusion Log includes an intrusion entry for port A2 at 4:51
p.m. on September 10, 1999, and you reboot the switch at 8:35 a.m. on September 14, 1999, the entry
for that intrusion would appear as prior to 14-Sept-99 8:35:00 AM. For more on port security and the
Intrusion Log, see the Software Update C.7.XX Release Notes for the HP ProCurve Switch 1600M,
2424M, 4000M, and 8000M, shipped with the switch and also available in the Support area of HP’s
ProCurve website at http://www.hp.com/go/procurve.
Switch 8000M Power Supply Requirements
If you plan to install six or more HP ProCurve Switch 100Base-FX modules (HP J4112A) in the Switch
8000M, you must first install a second Switch 4000M/8000M (Redundant) Power Supply (HP J4119A)
in the switch. Note that if a redundant power supply is installed and one of the switch’s power supplies
subsequently fails, you can replace the failed power supply without disrupting switch operation.
