Patch Release Note

Patch SB251-10 for Software Release 2.5.1

C613-10361-00 REV J

If a BIST was run at low temperatures, for example 5 or 10 degress celcius, 
on a G8 card, then a watchdog timer restart could occur.  The switch now 
checks for the real course of the external interrupts that occur when running 
BIST.

If the Gratuitous ARP feature was enabled on an IP interface, and an ARP 
packet arrived, (either ARP request, or reply) that had a Target IP address 
that was equal to the SenderIP address, then the ARP cache was not 
updated with the ARP packet’s source data.  This issue has been resolved.

If two line cards were inserted in quick succession, then a software restart 
could occasionally occur.  This issue has been resolved.

When the Built-In Self Test was run,  a fault would occasionally be reported 
which said that a MAC  address was not learnt during the loopback test.  
The ports in the BIST loopback test now remain in loopback.

Features in SB251-02

Patch file details are listed in Table 9:

Patch SB251-02 includes all issues resolved and enhancements released in 
previous patches for Software Release 2.5.1, and the following enhancements:

64 bit MIB counters were not incremented or cleared for port 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.
