Figure 6. Port Concepts in the Hybrid Model

Cisco IOS Software

The port concepts in the Cisco IOS Software model are similar to the hybrid software model. In the

Cisco IOS Software model, all system configurations are done from a single command line

interface; there is no separation between the Layer 2 and Layer 3 configuration tasks. The Layer 2

port concepts, such as access and trunk ports and Layer 3 VLAN interfaces (SVIs), still apply,

although with different syntax. Additionally, Cisco IOS Software offers the concept of a Layer 3

routed interface. Table 7 provides an overview of the different Cisco IOS Software port and

interface types. More detailed descriptions follow.

Table 7. Cisco IOS Software Port Concepts

Interface Type Purpose Sample Configuration

Routed Interface Traditional Cisco IOS Software routing

example: each port with unique network

interface gigabitethernet 1/1

ip address 10.10.10.1 255.255.255.0

ipx network 1

Routed SVI Single routed interface for all of the

switch ports assigned to a VLAN

interface vlan 10

ip address 10.10.11.1 255.255.255.0

ipx network 2

Layer 2 VLAN Single Layer 2 broadcast domain vlan 10

Access Switch Port

Interface

To group Layer 2 ports into a single

VLAN

interface gigabitethernet 1/1

switchport

switchport mode access

switchport access vlan 10

Trunk Switch Port

Interface

To configure Layer 2 port belonging to

different VLANs

Interface Gigabit Ethernet 1/1

Switchport

switchport trunk encap dot1q

switchport mode dynamic desirable

Note: Although the terms interface and port are used interchangeably in this document, the

Cisco IOS Software command line refers to ports as interfaces, while the Cisco Catalyst OS

command line refers to them strictly as ports.
