Hi Kimsunjoo,

I presume you are talking about ACL counters if so the please read the following (from a previous post of mine)

Try command:

> clear access-list counters

This clears the counters shown by the show access-list command.

To clear counters on an interface, go into config mode and issue this command: clear int ethernet0

(You must be in config mode for this command to work.)

To set speed/duplex, again go into config mode and issue this command: interface ethernet0 100full

Also, the following URL might be of interest...

thanks for your reply.

But My question is not clear access-list, clear interface but show ip traffic output's counters.

Below are many counters(such as total, errors).

I will attach show ip traffic output.

"clear traffic" Resets the counters for the show traffic command.

[sjkim]

You know, Cisco IOS have not the "clear traffic" command.

[lwierenga]

Sorry, wasn't paying attention thought we were talking about a pix. In that case it is clear counters all

[Placido Giordano]

Hi,

To do this on IOS the command is "clear ip traffic" and then do a "show ip traffic."
