6 Patch 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.
