Chapter 1 Configuring Interface Characteristics
Monitoring and Maintaining the Interfaces
Clearing and Resetting Interfaces and Counters
Table 1-7 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.
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.
show interfaces transceiver properties (Optional) Displays temperature, voltage, or amount of current on the
interface.
show interfaces [ interface-id ] [{ transceiver
properties | detail }] module number ]
Displays physical and operational status about an SFP module.
show running-config interface [ interface-id ] Displays the running configuration in RAM for the interface.
show version Displays the hardware configuration, software version, the names and
sources of configuration files, and the boot images.
show controllers ethernet-controller interface-id
phy
Displays the operational state of the auto-MDIX feature on the
interface.
show power inline [i nterface-id | module
switch-number ]
Displays PoE status for a switch or switch stack, for an interface, or
for a specific switch in the stack.
show power inline consumption Displays the power consumption data.
show power inline police Displays the power policing data.
