Chapter 11 Configuring Interface Characteristics
Monitoring and Maintaining the Interfaces
Clearing and Resetting Interfaces and Counters
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.
Shutting Down and Restarting the Interface
Shutting down an interface disables all functions on the specified interface and marks the interface as
unavailable on all monitoring command displays. This information is communicated to other network
servers through all dynamic routing protocols. The interface is not mentioned in any routing updates.
Beginning in privileged EXEC mode, follow these steps to shut down an interface:
Use the
no shutdown
interface configuration command to restart the interface.
To verify that an interface is disabled, enter the
show interfaces
privileged EXEC command. A disabled
interface is shown as
administratively down
in the display.
