Chapter 9 Configuring Interfaces
Monitoring and Maintaining the Interface
This example shows how to clear and reset the counters on Fast Ethernet interface 5/5:
Switch#
clear counters fastethernet 5/5
Clear "show interface" counters on this interface [confirm]
y
Switch#
*Sep 30 08:42:55: %CLEAR-5-COUNTERS: Clear counter on interface FastEthernet5/5
by vty1 (171.69.115.10)
Switch#
The
clear counters
command (without any arguments) clears all the current interface counters from all interfaces.
Note
The
clear counters
command does not clear counters retrieved with SNMP; it clears only those counters
displayed with the EXEC
show interfaces
command.
Shutting Down and Restarting an Interface
You can disable an interface, which 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.
To shut down an interface and then restart it, perform this task:
This example shows how to shut down Fast Ethernet interface 5/5:
Switch(config)#
interface fastethernet 5/5
Switch(config-if)#
shutdown
Switch(config-if)#
*Sep 30 08:33:47: %LINK-5-CHANGED: Interface FastEthernet5/5, changed state to a administratively down
Switch(config-if)#
This example shows how to reenable Fast Ethernet interface 5/5:
Switch(config-if)#
no shutdown
Switch(config-if)#
*Sep 30 08:36:00: %LINK-3-UPDOWN: Interface FastEthernet5/5, changed state to up
Switch(config-if)#
To verify whether an interface is disabled, enter the EXEC
show interfaces
command. An interface that has been shut down
appears as “administratively down.”
Command
Purpose
Switch#
clear counters
{
type slot/interface
}
Clears interface counters.
