Explanation

When designing a large data center using extended Layer 2 VLAN topologies, it is necessary to calculate the spanning tree logical and virtual ports in advance to ensure that spanning tree operates with optimal convergence and stability characteristics. trunks on the switch * active VLANs on trunks + number of non-trunking interfaces on the switch 2 Trunks * 100 Vlans + 2 = 202 Active Logical Interfaces
