Note:
Although the terms interface and port are sometimes used interchangeably in this document, the Cisco IOS
command line refers to ports as interfaces, while the CatOS command line refers to them only as ports.
Figure 4 illustrates the different Cisco IOS interface types and the commands to use the Layer 2 or Layer 3
functionality.
Figure 4
Port Concepts in the Cisco IOS Model
Interface Type Purpose Sample Configuration
Routed interface Traditional IOS 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
