2. If VLAN bridge does not support any rule for VID then apply the PVID of the port to the packet which came from that port VLAN bridge checks to see if the ingress port and the received packet are on the same VLAN If not drops it If yes forwards it to the associated ports Meanwhile this VLAN must be applied to the egress port or the packet will be dropped If ingress filtering is disabled VLAN bridge will only check the MAC address table to see if the destination VLAN exists If VLAN does not exist then drop the packet and if both DA and VLAN do not exist forwards the packet If just knows VLAN existed then floods the packet to all the ports the VLAN covers If we plan to deploy four VLANs in an office and use a switch to partition them we should check which ports belong to which VLAN first Assuming a 9 port switch is applied 41 Publication date Aug 2014 Revision A1 Name VID Port Members Marketing 2 2 a Administration Table 3 5 Next assigns IP address to each VLAN Usually we use 10 x x x as internal IP block Because there are total four VLANs in the network we must assign 4 IP blocks to each of them NET VID Network Address Marketing 2 10 1 2 0 24 Service 3 10 1 3 0 24 Sales 4 10 1 4 0 24 Administration 1 10 1 1 0 24 Table 3 6 Here we apply the subnet mask 255 255 255 and each VLAN is capable of supporting 254 nodes 42 Publication date Aug 2014 Rev

The process to check a received packet and compare its VID to the VLAN membership of the ingress port The ingress filtering can be set by per port When receiving a packet VLAN bridge examines if the VID in the frame s header presents If the VID of the received packet presents the VID of the packet is used And VLAN bridge will check its MAC address table to see if the destination ports are members of the same VLAN If both are members of the tagged VLAN then the packet will be forwarded If the packet is an untagged or a null tag packet the ingress port s PVID is applied to the packet VLAN bridge will then look up the MAC address table and determine to which ports the packet should be forwarded Next it will check to see if the destination ports belong to the same VLAN with that PVID If the destination ports are members of the VLAN used by ingress port the packet will be forwarded Note VID can not be 0 or 4095 Ingress Rule Each packet received by a VLAN aware bridge will be classified to a VLAN The classification rule is described as follows 1 If the VID of the packet is null VID VID 0 or this packet is an untagged packet a If there are still some other ways e g protocol MAC address application IP subnet etc to classify the incoming packets beside port based classification in implement and these approaches can offer non zero VID then use the value of VID offered by other classifications for VLAN s classificat
