Patch SB244-01 for Software Release 2.4.4
C613-10349-00 REV A
Features in SB244-01
Patch SB244-01 includes all issues resolved and enhancements released in
previous patches for Software Release 2.4.4, and the following enhancement:
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.
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.

Patch SB244-01 For SwitchBlade 4000 Series Switches and AT-9800 Series Switches 3
Patch SB244-01 for Software Release 2.4.4
C613-10349-00 REV A
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.
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.

4Patch Release Note
Patch SB244-01 for Software Release 2.4.4
C613-10349-00 REV A
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.
