Usage guidelines
If you want to observe new traffic statistics on a tunnel interface, you can use this command to clear old
statistics:
• If you do not specify any parameters, this command clears the statistics for all interfaces.
• If you specify only the tunnel keyword, this command clears the statistics for all tunnel interfaces.
• If you specify both the tunnel keyword and the number argument, this command clears the statistics
for the specified tunnel interface.
Examples
# Clear the statistics for the interface Tunnel 3.
<Sysname> reset counters interface tunnel 3
