How to Configure EtherSwitch HWICs

DETAILED STEPS
Verifying Configuration of an Interface Range Macro
Use the show running-configuration command to show the defined interface-range macro
configuration, as shown below:
Router# show running-configuration | include define
define interface-range first_three FastEthernet0/1/0 - 2

Interface Speed and Duplex Configuration Guidelines
When configuring an interface speed and duplex mode, note these guidelines:
• If both ends of the line support autonegotiation, Cisco highly recommends the default auto
negotiation settings.
• If one interface supports auto negotiation and the other end does not, configure duplex and speed on
both interfaces; do not use the auto setting on the supported side.
• Both ends of the line need to be configured to the same setting; for example, both hard-set or both
auto-negotiate. Mismatched settings are not supported.
Command or Action Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
define interface-range macro_name {FastEthernet
interface-id [ - interface-id] | {vlan vlan_ID
- vlan-ID} | [, FastEthernet interface-id [ -
interface-id]
Example:
Router(config)# define interface-range
first_three FastEthernet0/1/0 - 2
