Display Port Statistics

From the Ports page, you can view the port statistics for either of the following:

■

A single port or view. For details, refer to Display Port Statistics for a Single Port

■

All the ports. For details refer to Display Statistics for All Ports

Display Port Statistics for a Single Port

From the Ports > Ports > All Ports, select any port by clicking on the row. The quick view window that appears provides port statistics for that particular port. Each field is color-coded in the graphical representation.

By hovering over the graph, numerical value for each of the data points is visible as shown in Figure 1.

Figure 26

Numerical Values for Data Points on the Statistics Graph

Note:  GigaVUE-FM will display 9-11 data points in the graph.

You can modify the time lapse for measuring various data points by selecting the Minutes, Hour, Day, or Week button. Figure 2 shows the data points measured by hour.

Table 1: Port Statistics Definitions describes the port statistics available.

Table 1: Port Statistics Definitions

Counter	Definition	Notes
Packet Errors	Total Error Packets Received or Transmitted This indicates hardware detected errors. Error packets include undersize, FCS/CRC, MTU exceeded, fragments, and oversize packets. All packets that list under this counter are discarded and not processed further.	Excludes oversize packets without FCS/CRC. Packets larger than the MTU setting arriving on a network port are counted twice in the counter. So 1000 oversize packets would show up as 2000. This double-counting only happens with Oversize error packets.
Discards	Discards Received or Transmitted	Discards are counted in the following cases: ■   Traffic arriving at a network port that is not logically connected using a map or map passall. ■   Map rules/map rules applied on a network port. ■   In packets on a tool port. ■   Pause frames.
Packet Drops	Total Dropped Packets Received or Transmitted	Packets are dropped when a port’s bandwidth is exceeded due to oversubscription. Packets are dropped when they reach the port but before they are sent out.
Octets	Total Bytes Received or Transmitted Includes all valid and error frames with the exceptions noted in the adjacent columns.	Excludes undersize frames.
Buffer Usage	Percentage of buffer space used by packets transmitted or received	The buffer is used when the port reaches 100 percent utilization during a microburst. If the buffer reaches 100 percent utilization, packets may be dropped.
Utilization	Percentage of port utilization by packets received or transmitted
Packets	Total Packets Received or Transmitted Excludes multicast packets, broadcast packets, packets with FCS/CRC errors, MTU exceeded errors, oversize packets, and pause packets.	Excludes packets with FCS/CRC errors.

Display Statistics for All Ports

To view the statistics for all ports select, Ports > Ports > Statistics. The Ports Statistics page displays, which shows a table with the statistics for each port as shown in Figure 3. For the definitions of the statistics shown in the table, refer to Table 1: Port Statistics Definitions.

Figure 28

Port Statistics for All Ports

The information on the statistics page can be filtered as well as downloaded to an Excel spreadsheet. To export the statistics, click Export. The statics table is downloaded with a filename in the format Port_Stats_<yyyymmddhhmmss>; for example, Port_Stats_20161003172336.

To filter the port statistics, click Filter. A Filter Quick View opens, where you can specify how to filter ports displayed on the Statistics page.

The criteria that you can use to filter the port statistics is as follows:

Criteria	Description
Box/Slot ID	Display only those ports that match the specified box and slot IDs.
Port Alias	Display port with the specified alias.
Port ID	Display ports with specified number in the port ID. For example, if you specify 3 the result will also display ports that include the number 3, 13, 23, 30, and so on.
Type	Display ports with the specified port type. Select one of the following: ● Network ● Tool ● Inline Network ● Inline Tool ● GigaSMART ● Hybrid ● Stack
Admin Status	Display ports based on their current admin status. The possible selections are: ● All — display ports with a status of Enabled or Disabled. This is the default. ● Enabled — display ports with admin enabled ● Disabled — display ports with admin disabled
Link Status	Display ports based on their current link status: The possible selections are: ● All — display ports with a status of Up or Down. This is the default. ● Enabled — display ports with a link status of up. ● Disabled — display ports with a link status of down.
