Page 6: The Upgrade Process
The Upgrade Process Upgrading the BayStack 450 switch to software version V4.0.0 is a two-step process: Download the boot code image. Download the agent image. To properly upgrade the BayStack 450 switch, the boot code image must be downloaded first, before you download the agent image. If the agent image (the operational software) is downloaded before the boot code image, the software may not be programmed into the BayStack 450 switch FLASH memory. -

Page 9: Accessing The Software Images
Accessing the Software Images You can access the software image files directly from the Internet: Note: When upgrading the switch, you must download two images, the boot code image (the firmware) and the agent image (the software). Go to www25.nortelnetworks.com/software. Under the Switching Products (or Data and Internet) heading, select BayStack Switches - 450 10/100/1000 Switch, then click the Go button. -

"Authenticator" in an EAPOL protected network. • Gigabit Interface Converter (GBIC) MDA support -- The new Nortel Networks 450-1GBIC MDA is supported by software version V4.0.0. • Automatic PVID selection option -- If enabled, when you assign a port to a VLAN, your BayStack 450 switch automatically sets the PVID on that port to match the new VLAN number. -
Page 12: Known Restrictions
Known Restrictions The following known restrictions apply to software version V4.0.0 (and earlier versions): • Software version V4.0.0 does not support IGMP-v2 leave messages. • Software version V4.0.0, running on Rev B hardware (HW: RevB in the System Characteristics screen), does not support the BayStack 450-2M3/2S3 MDAs (ATM MDAs). - Page 13 MultiLink Trunking allows you to group ports of varying speeds (for example, you can group 10 Mb/s, 100 Mb/s, and 1000 Mb/s ports in any combination). Although this is a valid configuration, Nortel Networks recommends that you only group ports of equivalent speeds when configuring a trunk. The MultiLink Trunk algorithm distributes connections across all of the available links in the trunk, regardless of speed.
- Page 14 Tree Port Configuration screen) is the same as the Normal Learning value, except that the state transition timer is shortened to two seconds. Nortel Networks recommends using the Fast Learning value to optimize switch-to-endstation connections. When you connect one switch to another switch, the Normal Learning (default) value provides the best results.
- Page 15 • RMON Alarms and Event entries RMON Alarms and Event entries are not saved to nonvolatile random access memory (NVRAM). When a reset condition or power-down sequence occurs, the entries are not preserved. This conforms to the current RFC 1757 standard. All RMON Alarms and Events must be reentered.
- Page 16 If this happens, you can enable the ports again using the Port Configuration screen. • Configuring port mirroring monitor ports Nortel Networks recommends that you configure the port mirroring monitor port to be on the same stack unit as the mirrored ports. • Monitoring outgoing frames on a gigabit Ethernet port...

Page 17: Known Problems
• Downgrading your BayStack 450-12F switch You cannot downgrade your BayStack 450-12F switch or a stack configuration that contains a BayStack 450-12F switch, to a software version earlier than software version V1.3. Software versions earlier than V1.3 do not support the BayStack 450-12F switch. •... -
Page 18: Connecting To Accelar Gigabit Ports
• When mirroring a single MLT member, the monitor port will receive all of the unknown unicast traffic that is transmitted over the entire MLT. • When you connect the BayStack 450 switch to an Alteon network interface controller (NIC), the switch learns invalid MAC addresses whenever autonegotiation for a gigabit MDA port is enabled (the invalid MAC addresses eventually age out). -

SMF/MMF patch cord for 1000BASE-LX multimode applications. The offset SMF/MMF patch cord allows the same transceiver to be used for both multimode and single-mode fiber. See your Nortel Networks sales representative for more information about the SMF/MMF patch cord. The optical performance of this transceiver cannot be guaranteed when connected to a multimode fiber plant without the use of the special offset SMF/MMF (mode conditioning) patch cord. -
