Default VLAN

The Default VLAN and is part of the system startup configuration, and is by default VLAN 1. You may

make another VLAN the default VLAN. The default VLAN cannot be deleted, disabled, or configured

(you cannot assign it an IP address), and only untagged interfaces can belong to it.

When an interface is configured as a switchport automatically places it in the default VLAN as an

untagged interfaces. All switchports must belong to at least one VLAN, so to remove a switchport from the

default VLAN, you must place it as tagged or untagged in some other VLAN, or remove the

configuration.

FTOS supports up to 4093 port-based VLANs plus 1 Default VLAN.

E-Series ExaScale FTOS versions earlier than 8.2.1.0 for the E-Series ExaScale support 2094 VLANs.

Configuring a VLAN is a two-step process:

1. Create a VLAN. See page 1103.

2. Add a switchport as a tagged or untagged member port. See page 1104.

3. Optionally, assign an IP address to a VLAN to enable routing between VLANs. See page 1105.
