Time Based Flow Statistics

Use the Time Based Flow Statistics page to define criteria for collecting time-based statistics for specific traffic flows. The statistics include a per-interface hit count based on traffic that meets the match criteria configured in a rule for the interfaces included in the rule. The hit count statistics are collected only during the specified time range. The statistics application uses the system clock for time-based reporting. Configure the system clock (manually or through SNTP (Simple Network Time Protocol)) before using the time-based statistics feature.

To access this page, click System > Statistics > Time Based > Flow Based in the navigation menu.

Use the buttons to perform the following tasks:

To add a rule and define criteria for flow-based statistics that are collected within a time range, click Add and configure the desired settings.
To delete one or more flow-based rules for time-based statistics, select each entry to delete and click Remove.
Click Refresh to refresh the data on the screen with the present state of the data in the switch.
To add a set of time-based traffic group statistics to collect, click Add and configure the desired settings.
To delete one or more time-based statistics groups, select each entry to delete and click Remove.

Time Based Flow Statistics Fields

Field	Description
Reporting Methods	The methods for reporting the collected statistics at the end of every configured interval. To change the reporting methods for all flow-based statistics rules, click the Edit icon and select one or more methods. To reset the field to its default value, click the Reset icon. The available reporting methods are: None: The statistics are not reported to the console or an external server. They can be viewed only by using the web interface or by issuing a CLI command. Console: The statistics are displayed on the console. E-Mail: The statistics are sent to an e-mail address. The SNTP server and e-mail address information is configured by using the appropriate Email Alerts pages. Syslog: The statistics are sent to a remote syslog server. The syslog server information is configured on the Logging Hosts page.
Rule Id	The number that identifies the flow-based statistics collection rule.
Time Range	The name of the periodic or absolute time range to use for data collection. The time range is configured by using the Time Range Summary and Time Range Entry Summary pages. The time range must be configured on the system before the time-based statistics can be collected.
Match Conditions	The criteria a packet must meet to match the rule.
Interfaces	The interface or interfaces on which the flow-based rule is applied. Only traffic on the specified interfaces is checked against the rule.

After you click Add, the Time Based Flow Configuration window opens and allows you to configure a rule for traffic flow statistics. The match conditions are optional, but the rule must specify at least one match condition. The following information describes the match criteria fields that are available in this window.

Time Based Flow Configuration Fields

Field	Description
Match All	Select this option to indicate that all traffic matches the rule and is counted in the statistics. This option is exclusive to all other match criteria, so if Match All is selected, no other match criteria can be configured.
Source IP	The source IP address to match in the IPv4 packet header.
Destination IP	The destination IP address to match in the IPv4 packet header.
Source MAC	The source MAC address to match in the ingress frame header.
Destination MAC	The destination MAC address to match in the ingress frame header.
Source TCP Port	The TCP source port to match in the TCP header.
Destination TCP Port	The TCP destination port to match in the TCP header.
Source UDP Port	The UDP source port to match in the UDP header.
Destination UDP Port	The UDP destination port to match in the UDP header.
