Two solutions are proposed in the contribution. Complete then Ballot Back. Show Request Show Preformatted Request. Since the frame is a broadcast, it is forwarded to any ports that are classified as eligible to receive Red VLAN frames. The switch forwards the broadcast frame out all the eligible ports, Ports 3 and 4. The frame forwarded out Port 3 has its VLAN Tag stripped before transmission, and it is passed to Bridge 4 as a normal broadcast frame.
When Switch 1 receives the tagged broadcast frame, it also examines the tag and classifies the frame as belonging to the Red VLAN. In this case only the 1D trunk, Port 3, is eligible, as it is considered a member of all VLANs for forwarding purposes. The Mail Server receives the broadcast frame and recognizes it.
The Mail Server responds with a unicast frame to User B. This frame crosses the 1D Trunk and is received by Switch 1. The frame is then checked for eligibility and frame format for Port 2.
The frame is tagged and transmitted out Port 2. This tagged unicast frame is received by Switch 2. The frame is checked for eligibility and frame format for Port 2.
The frame is tagged and transmitted out port 2. Switch 4 receives the frame on its 1Q Trunk port, Port 4, and examines the frames Tag. User B is found to be located on Port 1. The frame is then checked for eligibility and frame format for Port 1. User B receives the Mail Servers response. Any further unicast traffic between the Mail Server and User B will be handled in the same fashion by the switches in the network.
This nal example illustrates how to restrict AppleTalk protocol trafc of a network to prevent unwanted multicast frames from slowing down the whole network and yet be able to send and receive frames associated with other protocols.
In this example, illustrated in Figure , the Publications Department is relocating from another site to the third oor. This network will consist of six computers and a printer using several protocols including the AppleTalk protocol. A characteristic of the AppleTalk protocol is to send all frames as multicast frames. Much of the existing network conguration can remain as it was for Example 3, 1D Trunk Connection to Switch 3 will link the trafc from Switch 5 to the buildings network backbone.
Two 1Q Trunk ports must be activated and congured on Switch 3, and one 1Q Trunk port must be activated and congured on Switch 4. Ports 2, 3, 4, 5, 6, 7, and 8 of Switch 5 are connected to the Publication Department devices. The same ports will also be congured to classify all other protocol frames into a second VLAN Yellow.
Switch 3. Switch 3 is set as follows: 1. Ports 2, and 4 are set as This allows traffic from Switch 4 to reach Switch 2 on the network backbone. Switch 5 is set as follows: 1. Any AppleTalk frame received on ports 2 through 8 will be broadcast to all other ports on Switch 5 associated with the AppleTalk protocol.
For example, if Port 2 received a frame with the AppleTalk protocol, Switch 5 would only transmit the frame to Ports 2, 3, 4, 6, 7, and 8. If a frame associated with any protocol other than AppleTalk for example, for the mail server is received on any of the Ports 2 through 8, the frame would be part of the Yellow VLAN and transmitted out Port 1 as a tagged frame to Switch 3 and handled in the same manner as previously described in the previous examples to route the frame to the Mail Server on the first floor.
Any unicast frames received via Port 1 that are destined for a device in the Yellow VLAN are transmitted to the correct device. Any broadcast frames received via Port 1 are transmitted to all the devices in the Yellow VLAN and handled in a similar manner as previously described in Example 2. F FID.

The value is in the range from 0 to 7. A larger value indicates a higher priority. If congestion occurs, the switch sends packets with the highest priority first. CFI is used to ensure compatibility between Ethernet and token ring networks. The value 0 indicates that the MAC address is encapsulated in canonical format, and the value 1 indicates that the MAC address is encapsulated in non-canonical format.
The CFI field has a fixed value of 0 on Ethernet networks. This increases the number of VLANs to x The inner VLAN tag in the packets is forwarded as payload of the packets. Jodi Haasz. This standard specifies protocols, procedures, and management objects for locally-unique assignment of bit and bit addresses in IEEE networks.
Peer-to-peer address claiming and address server capabilities are specified. IEEE P This amendment specifies a Unified Modeling Language UML -based information model and YANG data models that allow configuration and status reporting for bridges and bridge components as specified by this standard with the capabilities currently specified in clauses It further defines the relationship between the information and data model and models for the other management capabilities specified in this standard.

This standard specifies profiles for secure, highly reliable, deterministic latency, automotive in-vehicle bridged IEEE The scope of this standard is to define a protocol and management elements, suitable for advertising information to stations attached to the same IEEE LAN, for the purpose of populating physical topology and device discovery management information databases.
This standard defines a protocol that a Advertises connectivity and management information about the local station to adjacent stations on the same IEEE LAN. It specifies an encapsulation format that allows one or more user data frames and padding octets to be carried within the confidentiality protected data of consolidating frames, hiding the users MAC addresses and original frame sizes.
The transmitter can balance the privacy improvement against the loss of efficiency and delay by controlling the sizes of consolidating frames and when they are transmitted. This amendment also describes privacy considerations for the use, design, and deployment of bridged networks. This amendment specifies YANG modules that contain the EtherType information, including a compact human-readable name and description.
