Create A Vlan; Assign Interfaces To A Vlan - Dell C Series Quick Start Manual

Create a VLAN

The default virtual local area network (VLAN) is part of the system startup
configuration, and is by default, VLAN 1. You may make another VLAN the
default VLAN. You cannot delete, disable, or configure the default VLAN (you
cannot assign it an IP address), and only untagged interfaces can belong to it.
When you configure an interface, a switchport automatically places it in the
default VLAN as an untagged interface. All switchports must belong to at least
one VLAN, so to remove a switchport from the default VLAN, place it as
tagged or untagged in some other VLAN, or remove the switchport
configuration.
Task
Create a VLAN.
Display all VLANs.

Assign Interfaces to a VLAN

A port may either be an untagged member of a single VLAN, or a tagged
member of perhaps multiple VLANs.
• Untagged Ports — ports that 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.
• Tagged Ports — ports that 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.
When you configure an enabled port as a switchport, the port is placed in the
default VLAN. To remove a switchport from the default VLAN, remove the
switchport configuration. To move the port to another VLAN, add it to the
desired VLAN as either a tagged or untagged member.
To view just the interfaces that are in Layer 2 mode, enter the show interfaces
switchport command in EXEC mode.
