CR00017548 Switch, VLAN 3 Previously, when using subnet-based VLANs, only IP traffic matching the
source IP network was classified into the subnet-based VLAN. This did not
include ARPs.
This meant that subnet-based VLANs only worked if all traffic flow was
between ports in the same subnet-based VLAN, or if static ARP entries were
configured.
This issue has been resolved. You can now use a hardware filter to send ARP
packets to the CPU, which will process them appropriately. This means that
if you use subnet-based VLANs, you also need to add the following
hardware filter:
create classifier=1 ethformat=ethii-untagged protocol=0806
add switch hwfilter=1 classifier=1 action=discard,copy

CR00017692 Core 3 Stack dump information was not available in the show debug or show
system dump commands after a fatal exception.
This issue has been resolved.

CR00017744 Switch 3 When switch ports were under a heavy traffic load, BPDUs could become
corrupted (the CRC was missing from the end of the packet).
This issue has been resolved.

CR00017851 Firewall 3 When using policy routing in conjunction with Firewall NAT, a policy-routed
packet could be sent over an interface while the IP NAT rule that was
applied would belong to a different interface. This would result in the
packet having a mis-matched source IP address for the interface it was
forwarded over.
This issue has been resolved. When using policy routing and Firewall NAT,
the source address on the resulting forwarded packet will now follow the
IP NAT rule attached to the interface over which the packet is forwarded.
