GigaSwitch Bridge Statistics

GigaSwitch Bridge Statistics

The GigaSwitch Bridge Statistics icon subview menu accesses the

GigaSwitch Flooding Table.

Unknown Unicast Rate

Maximum bytes-per-second bandwidth of packets multicast because the destination address was not yet learned by the the bridge.

Multicast Rate

The maximum bytes-per-second bandwidth of packets multicast because the destination address is a multicast address.

The Flooding Table details the Qualifier, Class, Bytes Sent, Packets Sent, Geezers, Losers, and Hogs information for each of the active cards on the GigaSwitch.

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.

Configuring Cut Through Mapping

1.Double-click on the appropriate Bridge Port number to generate the Cut Through Table View.

2.Click on the Inbound and Outbound buttons so that they display the appropriate settings, either Enabled or Disabled.

3.Choose Save All Changes from the File menu.

4.Click on the Update button in the Cut Through Mapping table to view your changes.
