CR00017750 IP Gateway 2 When an IP interface went down, and the switch received traffic on another
interface that was destined for the down interface’s IP address, the switch
no longer processed that traffic locally. Instead, it sent the traffic out its
default route. For example, if vlan1 had an IP address of 192.168.1.1 and
the switch received a ping on vlan2 for 192.168.1.1, then the switch would
route the ping out its default route, instead of processing the ping packet
and sending a ping reply message back.
This issue has been resolved. Traffic that is directed at an IP interface will
now be processed regardless of the link state of the interface itself.

CR00017751 IGMP 2 Previously, IGMP packets that had a source IP address of 0.0.0.0 were not
accepted.
This issue has been resolved. Such packets are now accepted and
processed.

CR00017767 Switch 2 When the Ethernet interface of an AR770S router was under very heavy
load it could, very occasionally, enter a mode which had a high latency for
packets transmitted over the interface.
This issue has been resolved.

CR00018035 Log 2 After changing the destination of the permanent or temporary logs to
syslog, the router or switch would sometimes reboot when displaying the
dynamic configuration.
This issue has been resolved.

CR00018137 Switch, VLAN 2 Previously, multicast limiting did not limit the number of destination look-
up failure packets or multicast packets destined to reserved IP multicast
addresses. In a correctly-functioning network, rates of these packets are
very low, but in a network with a loop, rates can be very high.
This issue has been resolved. Multicast limiting now includes such packets.
