IGMP, VLAN

Disabling IGMP snooping correctly increased the number of L3 filter matches

available. However, if the configuration was saved and then run after a reboot,

the switch incorrectly limited the number of L3 filter matches to the number

available when IGMP snooping was enabled. If the maximum number of matches

had been configured, this meant that some matches were missing after a reboot.

This issue has been resolved.

When performing RFC1483 encapsulation of Ethernet frames, the AR44xS

ATM

routers did not pad frames out to the 64-byte minimum frame size (the RFC does

Ethernet

not require such padding to be performed). This resulted in an interoperability

issue with ATM switches that discarded (rather than padded) the undersize

frames upon decapsulating them.

The effect of this was that when an AR44xS router was connected to an ATM

network that contained such switches, the router could fail to connect at the PPP

session level.

This issue has been resolved. The router now always pads undersize Ethernet

frames to the 64-byte minimum frame size before it performs RFC1483

encapsulation. This avoids the possibility of this interoperability issue.
