6 Patch Release Note
Patch SB251-13 for Software Release 2.5.1
C613-10361-00 REV M
Browsing the dot1dTpFdbPort table with SNMPv2c sometimes gave
incorrect output. This issue has been resolved.
Setting RSTPTYPE to NORMAL, when normal has already been set, sets all
ports to the “sending RSTP” state process. This is referred to in IEEE 802.1w
as mCheck.
When RSTPTYPE was changed from STPCOMPATIBLE to NORMAL with
the SET STP command, the STP instance continued to send STP BPDUs
until an mCheck was performed by entering the SET STP
RSTPTYPE=NORMAL command again. This issue has been resolved so
that when RSTPTYPE is set to NORMAL an mCheck is performed, causing
the STP to start sending RSTP BPDUs immediately.
If a DNS lookup failed when using the UPLOAD command to load a file
with a host name, the file was sometimes deleted from FLASH. This issue
has been resolved.
MLD and MLD Snooping accepted MLD Query packets with a hop limit
greater than 1. Duplicate packets were forwarded when the hop limit was
not 1 and the payload was 0::0. This issue has been resolved. MLD and MLD
Snooping now require the hop limit to be 1.
Packets with bad ACK numbers were sometimes generated by the firewall
as part of the proxy TCP setup process. These packets sometimes caused
TCP sessions from the public side of the firewall to fail. This issue has been
resolved.
After the SHOW VRRP command was executed, incorrect trigger messages
were entered into the log. This issue has been resolved.
A fatal error sometimes occurred when using hardware filters if DMA
debug was enabled. This issue has been resolved.
Rate limiting sometimes prevented IGMP snooping and MLD snooping
from operating correctly. This issue has been resolved.
A fatal error occasionally occurred because of an error with internal
processing of the control blades. This issue has been resolved.
The SHOW SWITCH HOTSWAP command output displayed more than 4
blades on a 4 blade chassis. This issue has been resolved.
