Manage---Error/Drop Counters of Interfaces

[sharone.job]

Hi,

     Router 7609-S

How can we clear the couters of a particular interface?

How can we clear the counters of all interface with a single command?

Is it wise to clear the counters daily ?

Any relevent information on Error/Drop Counters Management, Welcome

Regards,

Sharone

Hi,

Here are all your options for clearing the counters with examples:

There is no need to clear the counter daily if your device is working correctly.

"clear counters" in privilege exec mode (device#) will globally clear all the interfaces.  The "?" is you friend when it comes to Cisco commands.  If you do a "clear counters ?"  it will give you interface options such as FastEthernet, GigabitEthernet, Vlan, etc.  The only time i clear counters on my devices is when i am troubleshooting problems.  If i find an interface that is producing CRC errors, i clear counters to troubleshoot the cause.  Here's a good command to check on dropped packets.

sh int | i line | drops
