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, itÕs also possible to get a sense of an interfaceÕs 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

NOTE

Unlike the Interface Detail window, which this window replaces, the Interface Statistics window does not offer Disable or Test options. These options are available in the Interface Group window, which can be accessed via the System Group window (select System Group... from the Device menu). Refer to your Generic SNMP UserÕs Guide for further information on the System Group and Interface Group windows.

Enabling and Disabling Ports

From the Port menus on the CSX200/400 Chassis View window, you can administratively enable and disable the ports.

When you administratively disable a bridge port, you disconnect that portÕs network from the bridge entirely. The port does not forward any packets, nor does it participate in Spanning Tree operations. Nodes connected to the network can still communicate with each other, but they canÕt communicate with the bridge or with other networks connected to the bridge. When you enable a port, the port moves from the Disabled state, through the Learning and Listening states, to the Forwarding state; bridge port state color codes will change accordingly.

To enable or disable a bridge port:
