Using the 7C0x SmartSwitch Bridge View
6-12 The Bridge Statistics Window
Figure 6-6. Bridge Statistics Window
The Bridge Statistics window displays the following information:
Bridging Type
Type refers to the type of bridging supported by the bridge.
• unknown
• transparent-only
Total Ports
Shows the total number of bridge ports installed in the 7C0x SmartSwitch chassis.
Port
Displays each port’s index number.
IfIndex
Interface index; a unique value for each network (interface) to which this port
connects. Only a WAN port will connect to more than one interface
simultaneously.
PortCircuit
When dealing with X.25 virtual circuits, it’s possible for two Port Indexes to have
the same IfIndex. In such a case, Port Circuit contains the value of a MIB object
instance unique to the port; otherwise, Port Circuit is equal to 0.0. For example, if
Port 1 maps to IfIndex 1 and Port 2 maps to Ifindex 1, then the Port Circuits are 1.1
and 1.2 respectively.
DelayExceedDiscard
The number of frames a port has discarded due to an excessive transit time
through the bridge.
