Note The show platform fwm info gatos-errors command increments 3 times for a given drop. Other expected drops Drop VLAN_MASK_TO_NULL DROP_NO_FABRIC_SELECTED DROP_INGRESS_ACL Description Traffic destined for the CPU interfaces; not actually a VLAN. Increments with VLAN_MASK_TO_NULL. Increments for an access list matching the frame. If an ACL is not applied, this will increment if a large amount of CPU-bound traffic is being received, and the rate limit in the hardware is enabled to protect NX-OS from Denial of Service. Queue is full When a queue is full, you need to increment discards in the respective queue on the ingress interface.
