Description

For an OpenFlow virtual switch, specify the number of seconds after which an invalid OpenFlow flow entry is deleted from the flow table.

If you do not configure the purge-flow-timer statement, the device purges invalid flows from hardware, but indefinitely retains the corresponding flow entries in the flow table. If you configure the purge-flow-timer statement, the device purges invalid flows from hardware, and after the specified number of seconds, the device deletes the invalid flow entries from the flow table. Configuring a value of 0 causes the device to immediately delete invalid flow entries from the flow table.

Note:

By default, if you remove an active OpenFlow interface from an existing OpenFlow configuration, flow entries that match on this interface as the ingress interface and flow entries that include this interface in their action list (for OpenFlow v1.0) or flow instructions (for OpenFlow v1.3.1) are invalid and are automatically purged from the flow table and from the hardware regardless of whether you configure the purge-flow-timer statement.

Options

seconds

Number of seconds after which an invalid flow entry is deleted from the flow table.

  • Range: 0 through 300

Required Privilege Level

admin—To view this statement in the configuration.

admin-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 13.3.
