MAC Address Learning

Chapter 1 Initial Settings
This switch uses SVL (Shared VLAN Learning) to learn MAC addresses. SVL is a method that retains a shared MAC address table for the entire switch. It differs from IVL, which retains a MAC address table for each VLAN. Be sure you understand how SVL works before you create a VLAN with the switch.
Differences between Operation of SVL and IVL
PC3 (VLAN 1, 2,3 PVID 3)
VLAN 1
Switch 1
Switch 2
VLAN 1 VLAN 2
PC1 (VLAN 1, PVID 1) PC2 (VLAN 2, PVID 2)
SVL
VLAN 2
VLAN 3
When PC 1 and PC 3 communicate, PC 3 is learned by port 1 on switch 2 so PC 2 and PC 3 cannot communicate.
IVL
When PC 1 and PC 3 communicate, PC 3 is learned by both VLAN 1 and VLAN 2 so PC 2 and PC 3 can communicate. However, frames sent from PC 3 to PC 1 are also delivered to PC 2.
