2 Patch Release Note

Features in SB251-01

PCR: 02555 Module: SWI Network affecting: No

Layer 2 filtering is now working correctly.

PCR: 02561 Module: SWI Network affecting: No

32 bit counters now only show 8 bit contents.

PCR: 02563 Module: SWI Network affecting: No

The IPM (Layer 3 Multicasting table) now updates correctly to add or delete
the ingress linecard to control blade ports, and the control blade to egress
linecard ports when updating forwarding.

PCR: 02568 Module: CORE Network affecting: No

The ENABLE SYSTEM SECURITY_MODE command was enabling the
system security mode, but after the switch was restarted the system security
mode was disabled again. Also, when NVS was re-initialised because, for
example a battery had been exhausted, the system could not make an SNMP
trap. These issues have been resolved.

PCR: 02576 Module: SWI Network affecting: No

When the DISABLE SWITCH PORT FLOW=PAUSE command was
executed on a port or ports, they would still appear to be enabled at a higher
level. This issue has been resolved.

PCR: 02396 Module: DHCP Network affecting: No

DHCP RENEW request messages are now unicast (as defined in the RFC),
not broadcast.

PCR: 02575 Module: SWI Network affecting: No

VLAN tagged multicast packets were incorrectly being sent over untagged
VLAN interfaces. This issue has been resolved.

PCR: 02574 Module: DVMRP Network affecting: No

Some change actions, and the resending of prune messages were not
operating correctly. This issue has been resolved.

PCR: 02582 Module: SWI Network affecting: No

Pause flow control is now disabled by default on all ports. This improves
performance of the switch when it is congested.

PCR: 02587 Module: OSPF Network affecting: No

When OSPF was enabled on startup, an OSPF interface would sometimes
stay in the DOWN state. This issue has been resolved.

PCR: 03001 Module: SWI CLASSIFIER Network affecting: No

The following parameters have been changed CREATE CLASSIFIER, SET
CLASSIFIER and SHOW CLASSIFIER commands:

• The MACTYPE parameter has been changed to
MACTYPE={L2UCAST|L2MCAST|L2BCAST|ANY}. This resolves
an error with internal hardware tables.
