IGMP 3 When IGMP fast leave was enabled and the switch received a leave message via
a trunk port, the switch only removed the port from the multicast group if the
port was the master trunk port.
This issue has been resolved. When fast leave is enabled, non-master trunk ports
now leave multicast groups as soon as the switch receives a leave message.

IGMP
IP Gateway
3 The IGMP Default Timeout Interval is automatically calculated by IGMP in
accordance with RFC 2236, but the following command allows you to over-ride
the calculated value:
set ip igmp timeout=value
Previously, the router or switch sometimes set the interval to the calculated value
instead of using the value entered in the command above.
This issue has been resolved.

DHCP
Snooping
3 Previously, DHCP snooping correctly refused to allocate new DHCP leases once
the maxleases value had been exceeded, but it did so by discarding the server’s
acknowledgement message instead of forwarding it to the client. Therefore, the
DHCP server recorded the address as allocated, which meant the IP address range
could be exhausted.
This issue has been resolved. The server no longer records addresses as allocated
once the maxleases value is exceeded.

Switch 3 On AR415S, AR44xS, AR750S and AR770S routers, when a switch port went
down or was reset by using the command reset switch port=number, this
deleted the dynamically-learned forwarding entries for all ports.
This issue has been resolved. Now entries are only deleted for the port that went
down or was specified in the command.
