Hierarchy Level


Configure logical queue-depth in the PFE for ip-options packets for a given protocol such as TCP, UDP, ICMP, and so on, except IGMP. The queue-depth indicates the number of ip-options packets that can be enqueued in the PFE logical queue, beyond which it will start dropping the packets. Currently, IGMP has a default queue-depth of 192 (which is not configurable), and other protocols have a cumulative default queue-depth of 25. The CLI supports configuration for a maximum of 16 protocols. The sum total of queue-depth for all the protocols should not exceed 1024 packets.
