Monitoring and Maintaining the Interfaces
Clearing and Resetting Interfaces and Counters
Table 11-7 lists the privileged EXEC mode clear commands that you can use to clear counters and reset
interfaces.
To clear the interface counters shown by the show interfaces privileged EXEC command, use the clear
counters privileged EXEC command. The clear counters command clears all current interface counters
from the interface unless you specify optional arguments that clear only a specific interface type from a
specific interface number.
Note The clear counters privileged EXEC command does not clear counters retrieved by using Simple
Network Management Protocol (SNMP), but only those seen with the show interface privileged EXEC
command.
