Installing the Software 25

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.

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.
