Displaying Statistical Information
Procedure
To display performance statistics:
1. Use the following menu sequence:
Main Menu
→
Status
→
Performance Statistics
2. Select the interface and type of information you want to view
(e.g.,
Performance Statistics
→
Port-1 Physical).
You can clear statistical information to start over when you want to observe and
estimate the frequency or duration of a specific condition (e.g., gathering
information for reporting a problem to the network).
The following sections provide information about the statistical metrics collected.
Physical Performance Statistics for All Interfaces
These statistics appear when Network, Port-1, Port-2, or BRI-B1 Physical is
selected from the Performance Statistics menu. They are only available when the
interface is enabled.
