C613-10349-00 REV C
Features in SB244-03
Patch SB244-03 includes all issues resolved and enhancements released in
previous patches for Software Release 2.4.4, and the following enhancements:
MLD snooping is now supported on AT-9800 Series Switches and Rapier i
Series Switches.
The following issues have been resolved:
• PIM was disabled when the RESET IP command was executed.
• PIM reverse path check was not working correctly.
• PIM_DM assert was not working correctly.
• DVMRP messages were not being flooded correctly.
• Executing the SHOW PPP command sometimes caused a fatal error.
• IP forwarding was not working correctly on SwitchBlade 4000 Series
Switches.
• Changes have been made for supporting non-contiguous IP
subnetworks.
The counter for transmitted ARP packets was incorrect. This issue has been
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.
The ADD IPV6 ND command was not displayed by the SHOW
CONFIGURATION DYNAMIC command. This issue has been resolved.
The ARP cache is now updated when a gratuitous ARP request or reply

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 file details are listed in Table 2:
Patch SB244-02 includes all issues resolved and enhancements released in
previous patches for Software Release 2.4.4, and the following enhancements:
Some parameters in MLD specific query messages were not working
correctly. This issue has been resolved.
The ENABLE IPV6 MTUDISCOVERY and SET IPV6 MTU INTERFACE

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.
This issue has been resolved.
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.

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.
