Switchport Mode Overview

Interfaces placed into "switchport" mode alone can pass one of the following types of traffic:

  1. Untagged traffic only for a single VLAN
  2. Tagged traffic only for multiple VLANs

Switchport Mode Configuration

Command

Purpose

FTOS# configure

Enter configuration mode.

FTOS(conf)# interface gi 0/1

Enter the specific physical interface.

FTOS(conf-if-gi-0/1)# switchport

Enable Layer 2 switchport mode. Interface will automatically be added to the Default VLAN and pass untagged traffic.

FTOS(conf-if-gi-0/1)# no shutdown

Enable the interface.

Hybrid Mode Overview

Hybrid mode plus switchport mode

  1. Placing an interface in "hybrid" mode allows the interface to pass both untagged and tagged traffic.
  2. Once in hybrid mode, interfaces can be added to a single VLAN as untagged and multiple additional VLANS as tagged
  3. The single untagged VLAN becomes the Native VLAN for that interface.

The native or untagged VLAN on the connecting switch interface should always match for proper switch management traffic to pass successfully.

Hybrid Mode Configuration

Command

Purpose

FTOS# configure

Enter configuration mode.

FTOS(conf)# interface gi 0/1

Enter the specific physical interface.

FTOS(conf-if-gi-0/1)# portmode hybrid

Only required if the interface must pass both untagged and tagged traffic. Must be configured prior to setting all Layer 2 configurations. Switchport mode must be removed before placing into hybrid mode.

FTOS(conf-if-gi-0/1)# switchport

Enable Layer 2 switchport mode. Interface will automatically be added to the Default VLAN and pass untagged traffic.

FTOS(conf-if-gi-0/1)# no shutdown

Enable the interface.

How to remove Hybrid and Switchport Configurations

Command

Purpose

FTOS# configure

Enter configuration mode.

FTOS(conf)# interface gi 0/1

Enter interface configuration mode.

FTOS(config-if-gi-0/1)# no switchport

Disable Layer 2 switchport mode. Interface must only be in default VLAN as untagged in order to remove.

FTOS(config-if-gi-0/1)# no portmode hybrid

Disable hybrid mode. Layer 2 switchport mode must be disabled prior to removing hybrid mode.

Before hybrid mode can be removed from an interface all layer 2 configurations have to be removed. Including any VLANs as tagged or untagged.
