Clearing and Resetting Interfaces and Counters
Table 6: Clear Commands for Interfaces
PurposeCommand
Clears interface counters.
clear counters [interface-id]
Resets the hardware logic on an interface.
clear interface interface-id
Resets the hardware logic on an asynchronous serial
line.
clear line [number | console 0 | vty number]
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.
