Ethernet switch

Time to refresh the MAC address table for

Routing based on MAC & VLAN ID

802.11ad as 802.1Q adds 4 bytes in the header of each packet incoming, the first 2 bytes concern of Tag Protocol IDentifier. This EtherType is fixed 0x9100 defines the new format "Vlan Stacking".

(default)

MTU in Byte

Take account the value of Max Packet Size [byte] when "802.1Q setting" is set as DISABLE or FALLBACK the switch adds 4 Bytes for internal S_Tag.

With 802.1Q in SECURE (that means that packet VID must be contained in Virtual LAN table list, otherwise the packet is discarded), no internal TAGs are added.

Example 1 – Site A&B Common Parameters

When the LAN interfaces are setted in Disable802.1Q or FALLBACK, according with Port Based VLAN the switch automatically add a S_VID for each incoming packet and remove it before comes out. Only the packets outgoing from PortA remain S_Tagged with default Vid of Origin port.

Example 1 – Site A&B LAN Interface

Enable the LAN interface in Full rate.

All the LAN interfaces should have the same configurations.
