Figure 41. VLAN Configuration
First we need to assign ports Fa0/1, Fa0/2, Fa0/3 and Fa0/4 to new VLANs
(default is VLAN 1). Port Fa0/1 and Fa0/2 are assigned to VLAN ID 42, and
ports Fa0/3 and Fa0/4 to VLAN ID 83.These IDs will be used when frames are
tagged (labeled), and have to be equal to the VLANs we have already
configured at the IBM Switch. All VLAN ports are left at Static Access Mode to
know what VLAN the port is belonging to. Choosing dynamic VLAN means
that the switch would map the port to a specific VLAN based on the
workstation’s MAC address with the help of an external server called VLAN
Manager Policy Server. We do not use that feature.
Building the VLAN Trunk begins with setting the Mode, 802.1Q Trunk,inthe
VLAN Membership menu, in our case for port Fa0/7. We click the Configure
Trunk button for Port Fa0/7 in the VLAN Membership menu, to access the
Port FA0/7 Trunk Configuration window shown in Figure 42 on page 63.
