Configure the Counter Sampling Interval

Configure the counter sampling interval values at port level to determine how often the sFlow agent polls and exports counters for a configured interface.

Before you begin

  • You must globally enable sFlow.

Procedure

  1. Enter GigabitEthernet Interface Configuration mode:

    enable

    configure terminal

    interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}

    Note

    Note

    If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

  2. Configure the counter sampling interval:

    sflow counter—interval <1–3600>

  3. Verify the configuration:

    show sflow interface {slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}

Example

Verify all slots use the default polling-interval configuration.

Switch:1(config-if)#sflow counter-interval 525
Switch:1(config-if)#show sflow interface 1/1-1/10

Variable Definitions

Use the data in the following table to use the sflow counter-interval and show sflow interface commands.

Variable

Value

<1–3600>

Specifies the polling interval for a slot.

Default value is 0 (disabled).

{slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}
Identifies the slot and port in one of the following formats:

  • a single slot and port (slot/port)

  • a range of slots and ports (slot/port-slot/port)

  • a series of slots and ports (slot/port,slot/port,slot/port)

  • all ports on the same slot (slot/all)

  • all ports on the switch (all)

If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
