Unit Statistics

NOTE:The Unit Statistics screen provides an easy method for viewing per-port performance. It displays port trafﬁc activity for each active port. Values are refreshed approximately every two seconds. The counters are reset after the values reach approxi- mately 4.2 billion. See Figure 6-2.

To view the Unit Statistics screen, take these steps from the Switch 2000 TR Main Menu:

1Select Switch Management.

The TR Management screen appears.

2Press [Space Bar] until Unit appears.

3Press [Down Arrow] until Statistics highlights.

4Press [Return].

The Unit Statistics screen appears.

5Select statistic category and view.

The Unit Statistics screen displays these buttons:

RECEIVED—The total number of frames that have been received by the port including frames with errors.

TRANSMITTED—The total number of frames trans- mitted by the port, including frames with errors.

FORWARDED—The total number of frames received and then forwarded by the port.

FILTERED—The total number of frames ﬁltered by this port. Frames are ﬁltered because the destination station was on the same segment as the source sta- tion.

BROADCASTS—The total number of broadcast frames seen by the port.

CLEAR SCREEN COUNTERS—Use this button to set screen counters back to zero. This clears only counters displayed in the Unit Statistics screen. It does not affect the counters on the device. This prevents remote SNMP stations from seeing network anoma- lies.
