User B’s MAC address is located, and Port 2 is identified as User B’s location. The frame is then checked for eligibility and frame format for Port 2. Since Port 2 is a 1Q Trunk port, it is eligible to transmit frames for all VLANs. The frame is tagged and transmitted out Port 4.4 EXAMPLE 4, ISOLATING NETWORK TRAFFIC ACCORDING TO PROTOCOL 4.4.1 Solving the Problem Figure 4-11 Example 4, Isolating Trafﬁc According to ProtocolSwitch 3 is set as follows Switch 5 is set as follows Port 2, VLAN ID 6, Protocol AppleTalk 802.1Q VLAN User’s Guide Chapter 4 Examples4-22 INDEX Numerics802.1Q VLAN User’s Guide IndexIndex-2 Index-3 Index802.1Q VLAN User’s Guide 802.1Q VLAN User’s Guide IndexIndex-4
