Configuration Sequence
Defining a Range Macro
A range macro allows you to create a name that defines a range on interfaces on the Cisco MWR 2941.
Follow these steps to configure an interface range macro.
Step 1 Enter enable mode.
Router> enable
Router#
Step 2 Enter configuration mode.
Router# configure terminal
Router(config)#
Step 3 Use the interface-range command to define the macro.
Router(config)# define interface-range first_three GigabitEthernet0/1 - 2
You can use the show running-configuration command to verify the interface-range macro
configuration.

Interface Speed and Duplex Configuration Guidelines
When configuring an interface speed and duplex mode, note these guidelines:
• Speed and duplex commands only apply to FastEthernet interfaces. They do not apply to the onboard
Gigabit Ethernet ports.
• If both ends of the line support autonegotiation, we highly recommend 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.
Caution Changing the interface speed and duplex mode configuration might shut down and reenable the interface
during the reconfiguration.
