The 9H42x-xx Module View
2-18 Viewing Module Information
Packets Transmitted (Transmit only)
Displays the number of packets transmitted by this interface.
Making Sense of Detail Statistics
The statistics available in this window can give you an idea of how an interface is
performing; by using the statistics in a few simple calculations, it’s also possible to
get a sense of an interface’s activity level:
To calculate the percentage of input errors:
Received Errors /Packets Received
To calculate the percentage of output errors:
Transmitted Errors /Packets Transmitted
To calculate the total number of inbound and outbound discards:
Received Discards + Transmitted Discards
To calculate the percentage of inbound packets that were discarded:
Received Discards /Packets Received
To calculate the percentage of outbound packets that were discarded:
Transmit Discards /Packets Transmitted
Using the Find Source Address Feature
You can use the Find Source Address option to discover the bridging interface
through which a specific MAC address is communicating with the 9H42x-xx
SmartSwitch. When you select Find Source Address from the Device menu, the
device’s Filtering Database is searched for an entry which designates the bridge
interface serving as the source port for packets from the selected MAC address. If
the search is successful, the associated port will flash on the Chassis View display;
if the search is unsuccessful, a window will appear indicating that fact.
To search for a source address:
1. Click on Device in the Module View window to display the Device menu.
2. Drag down to Find Source Address..., and release. The Find Source
Address window, Figure 2-7, will appear.
