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.

4
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.

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 SB251-05 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 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 SwitchBlade 4000 Series Switches and AT-9800 Series Switches  
7
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 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.
