Page 14: Switch Cascading In Topology
8-/16-/24-Port 10/100 PoE PSE Web Smart Switch 3.4 Switch Cascading in Topology Theoretically, the switch partitions the collision domain for each port in switch cascading so that you may uplink an unlimited number of switches. In practice, the network extension (cascading levels and overall diameter) must comply with the IEEE 802.3/802.3u and other 802.1 series protocol specifications, which limit the timing requirement from physical signals defined by the Media Access Control (MAC) and PHY802.3 series specification, and the timer from some OSI layer 2 protocols such as 802.1d, 802.1q, and LACP. - Page 15 Chapter 3: Installation Case2a: Port-based VLAN (See Figure 3-4).
