CR00021006 Switching 2 When ingress filtering was enabled on a port and a packet arrived on that
port with a VLAN identifier that the port was not a member of, the source
MAC address would be incorrectly learnt. This issue has been resolved and
in this situation the MAC address is no longer added to the forwarding
database.

VLAN
2 If a VLAN-tagged ARP request was received with a VLAN ID of a VLAN that
had previously existed but had been destroyed, the switch could reboot.
This issue has been resolved.

CR00021308 OSPF 2 In a configuration where two otherwise identical external OSPF routes had
been learnt to a particular destination over two different interfaces, when
one of the interfaces went down both routes would be permanently
removed from the routing table and would not be added until OSPF was
reset. This issue has been resolved. Only the route belonging to the downed
interface will be removed.

CR00021978 Switching 2 If an ARP was received on a port and the MAC associated with that ARP
subsequently moved to another port and had a new IP associated with it,
and the new port was on a different switch instance, then when the
original ARP timed out, the MAC would be removed from the switch's
forwarding database. This only happened if the ARP moved across switch
instances.
This issue has been resolved.
