CONFIGURATION mode

Dell(conf)# linecard number port number portmode quad

– linecard number port number specifies the line card and 40GbE port to be split. The line

card range is 0 to 11; the port range is 0 to 20.

– portmode quad configures a 40GbE port to operate in 4x10G mode.

For example: Dell(conf)# linecard 0 port 5 portmode quad

Creating a VLAN

The default VLAN is VLAN 1 (by default) and is stored in the startup configuration.

You can configure a different VLAN number as the default VLAN. You cannot delete or disable the default

VLAN 1; you cannot assign it an IP address. Only untagged interfaces can belong to the default VLAN.

When you configure an interface, the switchport command automatically places it in the default VLAN

as an untagged interface. All switchport interfaces must belong to at least one VLAN. To remove a

switchport from the default VLAN, configure it as a tagged or untagged member of another VLAN or

remove the switchport configuration.

• Create a VLAN

CONFIGURATION mode

Dell(conf)# interface vlan vlan-id

• Display all VLANs.

EXEC Privilege mode

Dell# show vlan vlan-id

Assigning Interfaces to a VLAN

You can only assign interfaces in Layer 2 mode to a VLAN using the tagged and untagged commands.

To place an interface in Layer 2 mode, use the switchport command. A port can be an untagged

member of a single VLAN or a tagged member of multiple VLANs. When you place an interface in Layer 2

mode using the

switchport command, the interface is automatically configured as untagged and

placed in the default VLAN (VLAN 1).

• Tagged ports append an 802.1Q tag to frames on egress and accept only tagged frames on ingress

(untagged frames are dropped). You must connect tagged ports to VLAN-aware devices.

• Untagged ports do not append an 802.1Q VLAN tag to frames on egress and do not accept tagged

frames on ingress (tagged frames are dropped). You must connect untagged ports to VLAN-unaware

devices. To remove an untagged port from the default VLAN, remove the switchport configuration.

To assign an interface to a VLAN:

1. Enter the VLAN ID to enter configuration mode and assign an interface.

CONFIGURATION mode

Dell(conf)# interface vlan vlan-id

The range of VLAN ID numbers is from 1 to 4094.

2. Assign a switchport interface to a VLAN as a tagged or untagged member.
