I am working with ethernet-switch i have query regarding VLAN. If any body knows Please give your answer.
Ethernet switch supports shared VLAN feature. Let say in-comming packet to any port is vlan-tagged packet. First, destination address lookup will be perform. Secondly Vlan-lookup will be perform based on current tag. but,if this tag with current packet is not program in the VLAN-table, i mean to say this tag is new for the switch. So, switch can not able to find that which port are the member of this vlan-tag.
In this case, what switch should do ?1)Drop the packet ? 2)Forward to destinatiion Port ? 3)Forward to internal CPU ?
Thanks in advance. Dilip.
