Layer 2 Switching Commands 408
On a storm control enabled interface, if the ingress rate of that type of packet
(L2 broadcast, multicast, or unicast) is greater than the configured threshold
level (as a percentage of port speed or as an absolute packets-per-second rate),
the switch forwarding-plane discards the excess traffic.
The speed command controls interface link speeds and auto-negotiation. If
speed is set to something other than auto, auto-negotiation is disabled on the
interface. Auto-negotiation will link at the highest possible speed supported
on the interface at full duplex.
clear counters

Syntax
clear counters [vrf vrf-name | stack-ports | switchport | interface-id ]
•
vrf-name —The name of the VRF instance on which the command
operates.
• stack-ports—Clears stack-port statistics.
• switchport—Clear all the interface counters
•
interface-id —An Ethernet or port-channel identifier. If specified, counters
are cleared for the individual interface.

User Guidelines
Use of the clear counters command with no parameters indicates that both
switch and all interface statistics are to be cleared. This command clears the
individual component counters. If a port-channel is specified, the command
clears the port channel counters, including the flap counters.
The VRF identified in the parameter must have been previously created or an
error is returned.
