Much of the existing network configuration can remain as it was for
Example 2. While a new 1Q Trunk port must be activated and configured
on Switch 2, and the operational modes of the switches must be changed,
there are no other real changes to the network above the first floor.
Switch 4
Switch 4 is set as follows:
1. The VLAN Operational Mode is set to OPEN using the Device/VLAN
Configuration screen.
2. The Forward Mode for the switch is set to YES, adding the Default
VLAN to the Egress List of every switch port.
Switch 2
Switch 2 is set as follows:
1. The VLAN Operational Mode is set to OPEN using the Device/VLAN
Configuration screen.
2. The Forward Mode for the switch is set to YES, adding the Default
VLAN to the Egress List of every switch port.
3. The port mode of port 4 is set using the Port Assignment screen:
• Port 4, Port Mode: 1Q Trunk
This causes port 4 to be set as an additional 802.1Q Trunk port, which
makes its port Egress List contain all VLANs, and all frames
forwarded out this port are forwarded as tagged frames.
Switch 1
Switch 1 is set as follows:
1. The VLAN Operational Mode is set to OPEN using the Device/VLAN
Configuration screen.
2. The Forward Mode for the switch is set to YES, adding the Default
VLAN to the Egress List of every switch port.
