Dell Force10 MXL Blade - Assign Interfaces to a VLAN

Virtual LANs (VLAN) | 627
To view the configured VLANs, use the show vlan command in EXEC privilege mode (Figure 37-3).
Figure 37-3. show vlan Command Example
A VLAN is active only if the VLAN contains interfaces and those interfaces are operationally up. In
Figure 37-3, VLAN 1 is inactive because it contains the interfaces that are not active. The other VLANs
listed in the Figure 37-3 contain enabled interfaces and are active.
When you delete a VLAN (using the
no interface vlan vlan-id command), any interfaces assigned to that
VLAN are assigned to the default VLAN as untagged interfaces.
Assign Interfaces to a VLAN
To assign interfaces in Layer 2 mode to a VLAN, use the tagged and untagged commands. To place an
interface in Layer 2 mode, use the
switchport command.
These Layer 2 interfaces can further be designated as tagged or untagged. For more information, refer to
the Interfaces and Configure Layer 2 (Data Link) Mode. When you place an interface in Layer 2 mode
using the
switchport command, the interface is automatically designated untagged and placed in the default
VLAN.
To view which interfaces are tagged or untagged and to which VLAN they belong, use the
show vlan
command. For example, Figure 37-3 shows that six VLANs are configured, and two interfaces are
assigned to VLAN 2. The Q column in the
show vlan command example notes whether the interface is
tagged (T) or untagged (U). For more information about this command, refer to the command statement in
the Layer 2 chapter of the FTOS Command Reference Guide.
To view just the interfaces that are in Layer 2 mode, use the
show interfaces switchport command in EXEC
privilege mode or EXEC mode.
Note: In a VLAN, the shutdown command stops Layer 3 (routed) traffic only. Layer 2 traffic continues to
pass through the VLAN. If the VLAN is not a routed VLAN (that is, configured with an IP address), the
shutdown command has no affect on VLAN traffic.
