The Upgrade Process
Upgrading the BayStack 450 switch to software version V4.0.0 is a two-step
process:
1.
Download the boot code image.
2.
Download the agent image.
To properly upgrade the BayStack 450 switch, the boot code image
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.
The switch indicat es a f ail ed im age lo ad a s foll o w s: An al te rnati ng LED patt ern i s
displayed on the BayStack 450-24T 10/100 status LEDs (ports 13 to 24), on the
BayStack 450-12T 10/100 status LEDs (ports 1 to 12), and on the BayStack
450-12F Link status LEDs (ports 1 to 12).
If this happ ens, cycle the s witch power (power off the switch, then power it on).
Use the Software Download screen to download the new boot code image. After
the boot co de image download completes, download the new agent image.
Upgrading to Software Version V4.0.0 in a Mixed Stack
When you upgrade a mixed stack1 to software version V4.0.0, you must first
upgrade the agent code, before you upgrade the boot block. Although this is the
inverse of the normal upgrade procedure, it is necessary to ensure a successful
software upgrade.

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).
•Limited support for EAPOL TLS Certificates
TLS certificates are supported in mixed stacks only. MD5-Challenge
authenticatrion is supported in all configurations.
•Mixed stack configurations
The following restrictions apply to mixed stack configurations:
--If you are managing your mixed stack using a console interface, connect
the console to a Business Policy Switch.
--Management VLAN functionality is operational only through ports that
are configured as both “ingress” and “egress” members for the
management VLAN.
--The following BayStack 450 switch features are not available in a mixed
stack configuration:
-SNMP Security
-Save Current Settings
-Support for the BayStack 450-2M3/2S3 MDAs (ATM MDAs)
•System reset due to MultiLink Trunking reconfiguration
If you add a new unit, that is configured with at least one bounded trunk
(with no distributed trunks
2
), into a stack that is configured with one or more
distributed trunks, the new unit automatically resets before entering the
operational mode of the stack.

Known Restrictions
•MultiLink Trunking
MultiLink T runking allo ws you to g roup ports of v aryi ng 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 , Nort el 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, regardle ss of speed.
•Monitoring outgoing frames on trunk member ports
When you monitor outgoing frames on a full-duplex port that is a MultiLink
trunk member, Nortel Networks recommends that you use the address-based
mirroring mode. If you use port-based mirroring with this type of
configuration, some frames may not be displayed.
•MultiLink Trunking interoperability with Accelar
*
When a Distributed MultiLink Trunk (DMLT) is connected to an Accelar
switch, and you reset one of the st ac k uni ts or change the spanning tree status
of the DMLT, each unit sends out a (standalone) BPDU frame through the
DMLT port. This can cause Accelar switches with software versions prior to
V2.0.5 to disable the DMLT.
311523-C Rev 00
If this happ ens, reset th e Accelar swi t ch. If resetting the Accelar switch does
not correct the problem, contact your Nortel Networks Technical Solutions
Center (see “How to Get Help” in
).

•BayStack switches automatically calculate the path cost for any given port,
based on the port’s speed and duplex settings. If you manually change the
path cost setting, the switch no longer automatically calculates the path cost
for that port.
•Spanning Tree Participation value disabled for monitor port
When you use the Port Mirr oring fe ature in a st andalone switch con f igurat ion,
the Spanning Tree Participation value for the monitor port is automatically set
to Disabled. If you then insert the same standalone switch into a stack, the
Spanning Tree Participation value for the previously configured monitor port
remains
Disabled. You must manually reset the Spanning Tree Participation
value to Normal Learning or Fast Learning using the Spanning Tree Port
Configuration scr ee n.

•IEEE 802.1D spanning tree parameters
Spanning tree parameters cannot be configured from the console interface
(CI) menus and screens.
Configuration support is available through the Bridge MIB using Simple
Network Management Protocol (SNMP). Refer to RFC 1493 for more
information.
•The spanning tree conf igurati on must be the same on bot h ends of a MultiLi nk
trunk.
•Spanning tree port participation
The Fast Learning value (used with the Participation field in the Spanning
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.
•MAC address-based security learning process
If you mov e a device from one port t o a nother during the MAC address-based
security learning pro cess, the de vice’s MAC address will move t o the new por t
and will no longer be allowed on the original port. A given MAC address can
be learned on only one port at a time.

•The BayStack 450-2M3 and the BayStack 450-2S3 MDAs do not support
MAC-based security, Autotopology protocol, and EAPOL.
•You cannot assign an

same protocol ID.
•Redundant gigabit Phy
You cannot use the redun dant gigabit Phy port ( the backup Phy port) to create
two different paths.
•Autonegotiation restriction with gigabit ports
The BayStack 450 switch’s gigabit MDA ports comply with IEEE 802.3z
Draft 3.2 and IEEE 802.3z Draft 4.1; however, the following restriction
applies to the autonegotiation feature:
-- Autonegotiation does not restart if an invalid code word is received from the

the entries are not pr eserve d. This conforms t o the current RF C 1757 standard.
All RMON Alarms and Events must be reentered.
•RMON Event Log table’s secondary index
The RMON Event Log table’s secondary index is not incremented when all of
the table’ s entries ha v e been used . In this cas e, the e xisting i ndex es are r eused.
Thus, the index number cannot be used to indicate the total number of log
entries received.
•RMON Histo ry Control entr ies
A maximum of 85 RMON History Control entries per stack unit are
supported. The entry exists on the unit containing the “ControlDataSource.”
•Changing from a stack unit to a standalone switch
When you change a switch from a stack unit into a standalone switch, or vice
versa, the IP address of the switch/stack changes. As a result, all existing
management applications that use the previous IP address are lost until you
reconnect using the new IP address.
•Console may display a blank screen
When you connect a console terminal to an operating switch through the
Comm Port, the console may display a blank screen. This is a normal
condition. Press [Ctrl]-C to refresh the screen or, to get beyond the Nortel
Networks logo screen, press [Ctrl]-Y.

•Adding or removing stack units
When you add a new unit to the stack or remove an existing stack unit, you
will not be able to perform IP management functions for approximately 30
seconds.
During this time period, the following can occur:
-- Packets are lost when performance testing with SmartBits or any other
traffic generator.
-- IP Multicast streams stop receiving.
-- TELNET sessions time out and users lose their TELNET connection
without warning. Users must re-establish lost TELNET sessions.

-- ICMP echo (PING) requests do not receive responses.
-- All IP-related processes fail temporarily.
•Tagged bridge protocol data units (BPDUs)
Tagged BPDUs are not supported in this version.
•Network interface controllers (NICs)
The MultiLink Trunking feature supports only multiport NICs that are
configured as a single MAC address, single IP address entity.
•Downgrading a switch or stack to a software version earlier than software
version V1.3.
Note:
Software versions earlier than software version V1.3 do not support
distributed trunking. You must remove any distributed trunks before you
downgrade the switch to sof tware versions earlier than so ftware version V 1.3
or problems will occur.
If you must downgrade a switch from software version V1.3 (or later) to an
earlier versi on, you must f irst remo ve an y ex isting dis trib uted tr unks using the
MultiLink T runk Conf iguration sc reen. You can remov e the trunk b y disabli ng

version V1.3 (or late r) to an e arli er v ers ion , some p orts ma y bec ome disa ble d.
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
When you monitor outgoing frames on a gigabit port, the multicast frames
that are generated by the switch (for example, BPDUs, Autotopology, and
IGMP) will not be seen on the monitor port.

•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 sof tware version V1.3. Software versions earli er than V1.3 do not
support the BayStack 450-12F switch.
•Software versions earlier than V3.1.0 do not support:
-- Mixed stacks that include Business Policy Switches
-- BayStack 450-2M3/2S3 (ATM MDAs).
•Stack reset when creating the first DMLT
When you create your first DMLT using SNMP management, your stack can
reset without warning. This reset is required to enable only the first DMLT in
a stack.

•If you are running IGMP multicast traffic over a DMLT while the IGMP
snooping feature is disabled, the IGMP traffic that is received on one link of
the DMLT will be looped back onto another link of the trunk.
To break the loop, disconnect one link of the DMLT or enable the IGMP
snooping feature.

•When mirroring a single ML T 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
autonegotiati on for a gigabit MDA port is enabled (the in val id MA C addresses
eventually age out). This problem occurs only when you reset the switch (via
the console interface main menu or during a power cycle) and does not affect
the correct operation of the BayStack 450 switch.
Connecting to Accelar Gigabit Ports
The BayStack 450 switch supports gigabit MDA port connections to the Nortel
Networks Accelar switch gigabit ports, with the following restrictions:
•Autonegotiation

1000BASE-LX Connectors
The 1000BASE-LX (gigabit) MDAs use a longwave 1300 nm, fiber optic
transceiver to connect devices over single-mode (5 km/3.1 mi) or multimode
(550 m/1,805 ft) fiber optic cables.
Note:
The transcei ver must be mode condi tioned e xter nally v ia a sp ecial o f fset
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 mo re information about the SMF/MMF patch cord.
The optical perf or ma nce 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.
The 1000BASE-LX MDA transceiver is designed to mechanically accommodate
the
single-mode ferrules
cord.
Multimode ferrules
1000BASE-LX Connectors
used on one end of the special offset SMF/MMF patch
can bind and cause damage to the transceiver.
311523-C Rev 00
Caution:
Do not connect multimode cables directly into the 1000BASE-LX
MDA transceiver. Connect a special offset SMF/MMF patch cord into the
transceiver, then connect the multimode cable into the SMF/MMF patch cord.
For more information about gigabit transmission over fiber optic cable and mode
conditioning, refer to :
