QoS config guidelines for cat4500 (extracts from config guides):
1) It is not possible to match IP fragments against configured IP extended ACLs to enforce QoS. IP fragments are transmitted as best effort. IP fragments are denoted by fields in the IP header.
2) It is not possible to match IP options against configured IP extended ACLs to enforce QoS. These packets are sent to the CPU and processed by software. IP options are denoted by fields in the IP header.
Question:
does this restrictions also apply for Cat 6500 ?
