Counter Information:
	• IPv4 Discards---	IPv4 Discards represent errors at the IP layer, for example the IP checksum error.
	• STP Discards---	STP Discards are incremented when the receive interface STP state is not forwarding
	the packets received.
	• Policy Discards---	Policy Discards are incremented when there are discards because of input policy on
	the interface.
	• ACL Drops---ACL drops indicate that incoming packets match an ACL entry with a drop action.
	• Receive Drops---	This drop increment represents a condition when no output port is determined for an
	ingress packet. Receive drops happen because of variety of reasons including IPv4, STP and policy
	discards. The drop counter increments in conjunction with one of the above counters or separately.
	• Vlan Discard---	Vlan Discard indicates vlan-based discards. For example, a vlan tagged packet ingressing

on a port which is not a member of the vlan.

This example shows how to clear all the input discard counters which is useful for debugging purposes.:
