Using the CLI to Configure a VLANThe tagged 1/0/5 command in Figure 3-17 not only assigns the port to VLAN 55, it also sets the PortVLAN ID (PVID) to 55, causing untagged frames transmitted by this port to be tagged as part of traffic forVLAN 55.Enabling Spanning Tree ProtocolSpanning Tree Protocol (STP) is off by default. Enable STP globally, and then enable STP on the desiredports. Using the CLI, you can enable spanning tree globally, and on all the ports with just two commands— spanning-tree and spanning-tree port mode enable all:Note: As noted in Enabling Ports on page 38, all ports are disabled by default. Enable themwith no shutdown all (Global Config mode), or individually with the no shutdown command oneach port.Note: If you need to assign many ports to the VLAN, you might use the Interface Range mode.Force10 (Config)#interface vlan 55Force10 (Conf-if-vl-55)#tagged 1/0/5Force10 (Conf-if-vl-55)#untagged 1/0/6
