Patch SB251-07 includes all issues resolved and enhancements released in

previous patches for Software Release 2.5.1, and the following enhancements:

PCR: 03399

Module: STP, SWI

Level: 1

With this enhancement:

•

STP and Port Trunking now work together correctly.

BDPU Forwarding is implemented. The BPDU Forwarding feature

configures the switch to forward all received STP BPDUs. Under

normal circumstances, the switch will not forward any received STP

BPDUs, even if STP is enabled.

This implementation is for standard STP, it does not guarantee that RSTP

and port trunking will work correctly together in all situations.

STP does not update the pathcost for trunked ports, which means that a

trunk group has the same pathcost as a single port. This may cause STP

Blocking where it is not expected. To overcome this, the user should

explicitly set the pathcost for the trunk group ports to be less than the

default value for a single port.

STP reconfigures if the Master port in a trunk group goes link down. If the

Master port in a trunk group goes link down, and a Non-Master port is still

link-up, then STP will go through the Listening>Learning>Forwarding

reconfiguration on the new Master port. This means that there will be a

switching outage on the trunk group whilst the new Master port transitions

to the Forwarding state.

Command handler changes:

•

The PORT parameter of the CREATE SWITCH TRUNK PORT and ADD

SWITCH TRUNK PORT commands must specify ports that have

identical STP port configurations.

•

The ENABLE STP and ENABLE STP PORT commands cannot be used

to enable STP operation on a port that has been disabled from STP

operation because of Port Trunking. Only the Master port in a trunk

group actively participates in the STP algorithm. Non-Master ports in

the trunk group are in the STP Disabled State.

•

The output for the SHOW STP PORT command has been modifed so

that Non-Master Ports in a trunk group do not take part in the STP

algorithm.

The output for the SHOW STP PORT command has been modified so

that it displays whether a user has set the PATHCOST value, or if it was

auto-configured.

Patch SB251-08 for Software Release 2.5.1

C613-10361-00 REV H

Patch Release Note

•

The PORT parameter of the SET STP PORT command specifies either all

the ports in a trunk group, or none of the ports in a trunk group.

The STPFORWARD parameter has been added to the ENABLE

SWITCH and DISABLE SWITCH commands. If STPFORWARD is

enabled, and there is no enabled STP instance, then the switch will

forward all received BPDUs. If STPFORWARD is enabled, and an STP

instance is enabled, then STPFORWARD will be disabled by default and

a message will be generated.

•

The SHOW SWITCH command now shows the status of the BPDU

Forwarding feature.

PCR: 03401

Module: SWI

An enhancement has been made to the Test module to optimise the

reception of the loopbacked packets that are used to confirm operation of

the switch ports.

Patch SB251-06 includes all issues resolved and enhancements released in

previous patches for Software Release 2.5.1, and the following enhancements:

PCR: 03340

Module: SWI, SYSR

Level: 1

After a power cycle, or a reboot command, the SwitchBlade would

occasionally repeatedly restart if it had two active controller cards. Also, the

Slave controller card would sometimes not take over if the Master controller

card failed.

Patch SB251-08 For SwitchBlade 4000 Series Switches and AT-9800 Series Switches

Patch SB251-05 includes all issues resolved and enhancements released in

previous patches for Software Release 2.5.1, and the following enhancements:

PCR: 03281

Module: SWI

Level: 2

Specifying the PORT and SPEED parameters with the CREATE SWITCH

TRUNK command did not set ports in a trunk group to advertise the correct

trunk group speed and duplex mode. This issue has been resolved.

PCR: 03313

Module: SWI

Level: 1

A power cycle on the switch could cause the console port to become frozen

if a port was in a link up state. If a port went into a link down state, then the

console port became unfrozen. If RESTART REBOOT or RESTART

SWITCH commands were used, then the console port functioned correctly.

This issue has been resolved.

Patch SB251-04 includes all issues resolved and enhancements released in

previous patches for Software Release 2.5.1, and the following enhancements:

PCR: 03226

Module: SWI

Level: 2

An internal misconfiguration of memory occurred when an M3 control card

and an M5 control card were installed, and the M3 control card was acting

as the Master. This could cause unexpected restarts. This issue has been

resolved.

PCR: 03228

Module: SWI

Level: 1

On a 48 port line card, or a 32F card, if Port 1 went down, or was

disconnected, then traffic on Port 13 was also stopped, and vice versa. The

same issue affected other pairs of ports. This issue has been resolved.

PCR: 03230

Module: SWI

Level: 2

Port speeds on trunk ports sometimes had to be set using the SET SWITCH

PORT command instead of automatically adopting the trunk group speed.

If a port was added to a trunk group and the port status was ‘up’, (that is, it

was correctly connected to another port) then the trunk group speed should

have applied to all the ports in the trunk, but it did not. Similarly, if a port

was added to a trunk group, and the port status was ‘down’, but it was later

linked correctly, then the trunk group speed should have applied to the

ports in the trunk. This issue has been resolved.

Patch SB251-08 for Software Release 2.5.1

C613-10361-00 REV H

Patch Release Note

PCR: 03243

Module: SWI

Level: 2

After autonegotiation had finished between two ports, the port on the

SwitchBlade would not show link up status when the SHOW SWITCH

PORT command was executed. The autonegotiation process is now

restarted if autonegotiation is completed and the link is shown as down.

PCR: 03249

Module: SWI

Level: 4

The LEDs on line cards now continue to flash when activity exists.

Previously if a cable was connected and disconnected to Line 48 and G8

ports, with traffic being transmitted from the other end, then the LED

would stop flashing, even when there was activity on the link.

Patch SB251-03 includes all issues resolved and enhancements released in

previous patches for Software Release 2.5.1, and the following enhancements:

PCR: 02361

Module: SWI

Level: 4

The SwitchBlade mirror port field on the second instance of a switch chip

was displaying as though it was the first instance. For example, if 2.26 was

configured as the mirror port, the GUI mirror object would return 2.2. The

first chip instance was not affected. This issue has been resolved.

PCR: 02527

Module: TCP

Level:3

TCP6 did not send a TCP Reset message under some circumstances, for

example when the Telnet server was disabled. This issue has been resolved.

PCR: 03025

Module: GUI

Level:2

A buffer address was incrementing and not returning buffers for reuse

when the command line interface was accessed via the GUI interface. This

issue has been resolved.

PCR: 03055

Module: SWI

Level: 4

If the SET SWITCH BLADE command was executed with the default

settings, then the default settings were added to the configuration file. The

SET SWITCH BLADE settings are now only added to the configuration file

if they differ from the default settings.

Patch SB251-08 for Software Release 2.5.1

C613-10361-00 REV H

Patch SB251-08 For SwitchBlade 4000 Series Switches and AT-9800 Series Switches

PCR: 03060

Module: CORE, SWI

Level: 3

Support has been added, to the MIB-2 interface MIB, for the port interface.

This means that port counters can now be shown.

PCR: 03066

Module: SWI

Level: 2

If a hardware filter was added to the switch, with a source VLAN and a

destination port of 1, then a host connected to the switch could not PING a

host on a different port. This issue has been resolved.

PCR: 03071

Module: CORE

Level: 2

An unexpected restart that occurred when upgrading a SwitchBlade from

Release 2.4.4 to Release 2.5.1 was caused by NVS generating an SNMP trap.

This issue has been resolved.

PCR: 03079

Module: IPG, SWI

Level: 1

Static routes were occasionally not added to all hardware tables across all

instances. This would affect connectivity if an instance had a default route

added to its table that pointed out one of its ports. This issue has been

resolved.

PCR: 03088

Module: SWI

Level: 2

Ports could not be added to the default VLAN after a hotswap, if the default

VLAN was Protocol, Subnet, MAC address, or Limited protocol based. This

issue has been resolved.

PCR: 03105

Module: FIREWALL

Level: 3

Incorrect handling of TCP sessions, and poor load balancing performance

could be caused by TCP virtual balancers not selecting a new resource if

required. This issue has been resolved.

PCR: 03112

Module: IPV6

Level: 3

The ADD IPV6 ND command now has a PORT parameter which means that

it can be associated with the VLAN parameter.

PCR: 03118

Module: CORE

Level: 4

Changes have been made to the SysDescription.

PCR: 03119

Module: CLASSIFIER

Level: 4

TCP source and TCP destination ports were swapped when viewed in the

GUI. This issue has been resolved.

PCR: 03138

Module: SWI

L evel: 2

Packets that were sent out a default route could have an incorrect source IP

address, if the interface route to the destination IP address existed but was

down. This issue has been resolved.

PCR: 03141

Module: IPG

Level: 3

Packets could be sent with an incorrect source address if a route was added

to a VLAN and another VLAN had an IP interface configured that was in

the same subnet as the route. This issue has been resolved.

Patch SB251-08 for Software Release 2.5.1

C613-10361-00 REV H

Patch Release Note

PCR: 03142

Module: SWI

Level: 1

If a BIST was run at low temperatures, for example 5 or 10 degress celcius,

on a G8 card, then a watchdog timer restart could occur. The switch now

checks for the real course of the external interrupts that occur when running

BIST.

PCR: 03148

Module: IPG

Level: 3

If the Gratuitous ARP feature was enabled on an IP interface, and an ARP

packet arrived, (either ARP request, or reply) that had a Target IP address

that was equal to the SenderIP address, then the ARP cache was not

updated with the ARP packet’s source data. This issue has been resolved.

PCR: 03191

Module: SWI

Level: 1

If two line cards were inserted in quick succession, then a software restart

could occasionally occur. This issue has been resolved.

PCR: 03192

Module: SWI

Level: 2

When the Built-In Self Test was run, a fault would occasionally be reported

which said that a MAC address was not learnt during the loopback test.

The ports in the BIST loopback test now remain in loopback.
