17.Press the SPACE bar to toggle the field to display Enabled.

18.Use the arrow keys to highlight the SAVE command at the bottom of the screen.

19.Press ENTER. The message “SAVED OK” displays. The switch activates the new VLAN.

This effectively completes the conﬁguration of a single VLAN, assigning it to a port, and conﬁguring the switch to forward the frames received on that port to be forwarded with the VLAN information included in the frame.

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.
