destination address is a multicast address.

GigaSwitch Cut Through Mapping

The GigaSwitch Cut Through Mapping table allows the user to enable or

disable the Inbound or Outbound Cut Through Mapping application for each

of the GigaSwitch Bridge Ports. The Cut Through Mapping feature allows

packets with known IP addresses to travel through the GigaSwitch with out

being temporarily stored within the GigaSwitch. Packets without known IP

addresses for their destination are temporarily delayed while the GigaSwitch

learns the IP address.

The default setting for each of the Bridge Ports is Enabled for both the

Inbound and Outbound Cut Through Mapping applications.

Through Table View.

appropriate settings, either Enabled or Disabled.

your changes.
