Patch SB251-01 for Software Release 2.5.1
C613-10361-00 REV A
Features in SB251-01
Layer 2 filtering is now working correctly.
32 bit counters now only show 8 bit contents.
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.
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.
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.
DHCP RENEW request messages are now unicast (as defined in the RFC),
not broadcast.
VLAN tagged multicast packets were incorrectly being sent over untagged
VLAN interfaces. This issue has been resolved.
Some change actions, and the resending of prune messages were not
operating correctly. This issue has been resolved.
Pause flow control is now disabled by default on all ports. This improves
performance of the switch when it is congested.
When OSPF was enabled on startup, an OSPF interface would sometimes
stay in the DOWN state. This issue has been resolved.
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.
