COMMAND LINE INTERFACE

clear counters

This command clears statistics on an interface.

Syntax

clear counters interface interface

•ethernet unit/port

-unit - This is device 1.

-port - Port number.

•port-channel channel-id(Range: 1-6)

Default Setting

None

Command Mode

Privileged Exec

Command Usage

Statistics are only initialized for a power reset. This command sets the base value for displayed statistics to zero for the current management session. However, if you log out and back into the management interface, the statistics displayed will show the absolute value accumulated since the last power reset.

Example

The following example clears statistics on port 5.
