resolved.

On SwitchBlade 4000 Series Switches, the MIB browser could not see the

slave controller card. This issue has been resolved.

When SwitchBlade 4000 Series Switches were operating with a full set of

line cards, and the test module was enabled for all interfaces, an excessive

amount of traffic was generated. This issue has been resolved.

VLAN number 4077 could not be created. This issue has been resolved.

When there were 4000 VLANs, executing the DESTROY VLAN=ALL

command caused a fatal error. This issue has been resolved.

Patch SB244-03 for Software Release 2.4.4

C613-10349-00 REV C

288MB RDRAM was initialised incorrectly, resulting in unpredictable

behaviour. This issue has been resolved.

Inuse DHCP entries (that are displayed in the SHOW DHCP CLIENT

command) will now expire and be reclaimed.

It was possible to add the same IPv6 prefix to different IPv6 interfaces. This

issue has been resolved.

The wrong error message was displayed if PPP compression over L2TP was

attempted. The correct message is now generated, stating that the CREATE

PPP command is invalid.

Some parameters in the SET IP IGMP command had incorrect ranges. This

issue has been resolved. The correct ranges are:

SET IP IGMP [LMQI=1..255] [LMQC=1..5]

[QUERYINTERVAL=1..65535] [QUERYRESPONSEINTERVAL=1..255]

[ROBUSTNESS=1..5] [TIMEOUT=1..65535]

If multiple IPv6 interfaces shared the same link-local address, pings to the

link-local address sometimes failed. This issue has been resolved.

Loading files to NVS caused a fatal error. This issue has been resolved.

A warning was not given if the egress limit for a port was not set to a

multiple of 64. This issue has been resolved.

ARP entries on the SwitchBlade 4000 Series Switch controller card are now

updated correctly if a device changes to a different line card.

The source net mask has been removed from DVMRP prune, graft and

graft-ack messages.

Executing the PING command sometimes caused a memory leak. This issue

has been resolved.

Untagged IGMP packets were erroneously sent out of tagged ports. This

issue has been resolved.

Patch SB244-03 for Software Release 2.4.4

C613-10349-00 REV C

Sometimes a port reported an interface as being down, but the port counters

kept incrementing. This issue has been resolved.

The CREATE TRIGGER MODULE=SWITCH command now recognises

ports in x.y notation when specifying the PORT parameter.

A fatal error occurred on SwitchBlade 4000 Series Switches when booting

from a script that added ports to a trunk group that was hot swapped out.

Support for multi-homed interfaces has been added.

The board descriptions have changed for some instances of AT-9800 Series

Switches.

When a Telnet session was closed, SWITCH debug was not disabled if it had

been enabled for the Telnet session. This issue has been resolved.

After an ASYN port test, the port is now reset to its pre-test state if the test

was started by a user connected to the same ASYN port.

The Built-in Self Test failed on SwitchBlade chassis. This issue has been

resolved.

The configuration was not restored correctly after a line card was hot

swapped out. This issue has been resolved.

A string compare error was occurring in the conditional statement of the

script. This issue has been resolved.

6Patch Release Note

Patch SB244-03 for Software Release 2.4.4

C613-10349-00 REV C

Features in SB244-01

Patch file details are listed in Table 3:

Patch SB244-01 includes the following enhancements:

When an interface went down (or was disabled) on an AS border router, the

external routes were not removed from the routing domain. Such routes are

now removed by premature aging.

The learning unit was locking under heavy load. This could result in pings

to a network device failing, and over an hour all dynamic MAC addresses

could be lost. Sometimes a large number of pause frames were generated by

the system. This issue has been resolved.

When an IP Multihomed interface was used as an OSPF interface,

neighbour relationships were only established if the IP interface for OSPF

was added first in the configuration. Now, OSPF establishes neighbour

relationships regardless of the IP Multihomed interface configuration order.

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

was displaying as though it was the first instance. This issue has been

resolved.

The following issues have been resolved:

• IP route updating was not working correctly

• IGMP snooping behaviour was incorrect

• The SHOW DVMRP FORWARDING command displayed incorrect

port numbers.

DHCP RENEW request messages are now unicast (as defined in the RFC),

not broadcast.

After a prune lifetime had expired, the interface was not joined back to the

DVMRP multicast delivery tree. This issue has been resolved.

Patch SB244-03 For SwitchBlade 4000 Series Switches and AT-9800 Series Switches 7

Patch SB244-03 for Software Release 2.4.4

C613-10349-00 REV C

The following issues have been resolved:

• It was possible to assign the same network on different IPV6 interfaces

• The loopback address was being added to other interfaces

• The tunnel configuration was not showing correctly in IPV6

configuration commands

• RIPv6 now sets the metric of routes for interfaces that are DOWN to 16,

and immediately sends responses when the link status of VLAN

interfaces changes.

Neighbour discovery and PIM6 caused a fatal error when IPv6 was not

enabled, or when the IPv6 feature license was not present. This issue has

been resolved.

A Router-Alert option has been added. Also, the SHOW IPV6 MLD

INTERFACE command now works correctly.

ICMP was sending too many messages back as responses to fragmented

packets. This issue has been resolved.

A warning now appears when the DELETE IP INTERFACE command is

executed before the DELETE DVMRP INTERFACE command.

VRRP pre-empt mode was not working with advertisement updates of 1

second or more because this did not allow for interface start time on startup.

Now a check is made to verify that interfaces are UP before timers are

started.

Static IP ARP entries could not be added to hardware at boot time. Also, an

IPX circuit could not be deleted from hardware. These issues have been

resolved.

Multicasting forwarding was not working correctly. This issue has been

resolved.

The IGMP port list was not updating correctly when a port went down. This

issue has been resolved.

ICMPv6 was returning an error for non-zero fragment offsets. This issue has

been resolved.

8Patch Release Note

Patch SB244-03 for Software Release 2.4.4

C613-10349-00 REV C

Packets with a RIP source address and next hop address that are not on the

same subnet as the interface will now be processed. If the received next hop

is not on the same subnet, it is treated as 0.0.0.0.

On GBICs, the link was forced up when the transmit fibre was removed.

Once up, the link could not be taken down again by removing the transmit

fibre. This issue has been resolved.

IGMP messages sometimes caused a fatal error. This issue has been

resolved.

Multicast downstream groups are now added and deleted correctly.

Errata

AT-9800 Series Switches do not have Ethernet interfaces (for example, eth0).

Previously released documentation incorrectly states that these interface types

are valid. AT-9800 switch ports are Ethernet ports, and these are referenced in

commands with the PORT parameter.

IPSec and ISAKMP are not available on the 2.4.4 release for SwitchBlade 4000

Series Switches and AT-9800 Series Switches.
