2 Patch Release Note
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:
PCR: 01285 Module: OSPF Network affecting: No
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.
PCR: 02353 Module: SWI Network affecting: No
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.
PCR: 02359 Module: IPG Network affecting: No
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.
PCR: 02361 Module: SWI Network affecting: No
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.
PCR: 02394 Module: IPG, SWI, DVMRP Network affecting: No
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.
PCR: 02396 Module: DHCP Network affecting: No
DHCP RENEW request messages are now unicast (as defined in the RFC),
not broadcast.
PCR: 02397 Module: DVMRP Network affecting: No
After a prune lifetime had expired, the interface was not joined back to the
DVMRP multicast delivery tree. This issue has been resolved.
PCR: 02398 Module: IPV6 Network affecting: No
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.
