Share VLAN Configuration 

Share VLAN Configuration 

Overview 

As a VLAN sharing addresses, the Share VLAN can solve the problem that the 

packets to this MAC address will be broadcast in another VLAN while the switch 

learns a MAC address in a VLAN. When a VLAN is set to be the Share VLAN, 

however, it will replicate its learned dynamic and static MAC addresses to other 

VLANs, and  other  VLANs also replicate their learned dynamic and static MAC 

addresses to the Share VLAN. The address triggering this address application 

procedure is called home address and the replicated addresses are called sub 

addresses.  The  sub  addresses  will  not  trigger  replication  anymore.  When  the 

home address is deleted or aged out, the sub addresses are deleted or aged out 

at the same time. However, deleting sub addresses will not bring any influence 

on the home address.   

Application Model   

Packets are forwarded by searching the address table. If the address table has 

not  the  destination  address,  the  packets  will  be  broadcasted  in  a  VLAN,  as 

shown in Figure 1. 

 

 

The VID of the packets from PC1 to the server is 2. The switch will learn PC1

’s 

address, as shown in Table 1.
