CR00020937 QoS 2 Under some configurations, the switch could reboot when:
■ applying a QoS policy to the same port twice (by using the command set
qos port=x policy=x).
■ adding classifiers to a QoS flowgroup that has not been associated with
a policy or traffic classifier.
These issues have been resolved.

CR00021623 Switching 2 Previously when a MAC learning limit was enabled along with MAC re-
learning for a switch port, if the same MAC addresses were learnt by
another port in the same vlan (a 'station move' event), the learn limit on the
first port was not decremented even though the MAC addresses were no
longer tied to it. This would mean that after the port reached its learn limit,
it would stop learning any new MAC addresses even if all of the previously
learnt addresses were then moved to different ports.
This issue has been resolved. Now when a MAC address undergoes a
'station move' event, the learn counter of the first switch port will be
decremented when the MAC is removed, so the port can no longer get into
a state where it will refuse to learn more MAC addresses.

CR00021993 EPSR 2 Previously when an EPSR+ ring was recovering from multiple link failure, IP
connectivity could be lost for longer than necessary.
This issue has been resolved.

CR00022057 IPv6 2 Previously, if a router or switch received a neighbour discovery
advertisement with a target link-layer address option of 00-00-00-00-00-
00, the device may have restarted. This issue has been resolved.

CR00022153 DHCP 2 Previously, on a router or switch using multihoming, the DHCP server on the
router or switch could sometimes assign multiple IP address to the same
client. This occurred when a client's DHCP Discover message was received
through more than one logical interface on the router or switch.
This issue has been resolved.
