PCR: 03142

Module: SWI

Level: 1

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.

PCR: 03148

Module: IPG

Level: 3

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.

PCR: 03191

Module: SWI

Level: 1

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

PCR: 03192

Module: SWI

Level: 2

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.
