A hub stack composed of multiple hubs (up to four) cascaded together as the instruction in section 2.4 can be treated as a single
If interconnection of the 10M network and the 100M network is re- quired, one and only one
A hub stack still complies with IEEE 802.3u Class II specifications. Only one connection to another Class II hub via UTP cable is allowed for a hub stack. The following figure illustrates the maximum network span containing two hub stacks:
