How to Configure Gigabit EtherSwitch EHWICs

Configuring the Cisco Gigabit EtherSwitch EHWIC

OL-23155-01

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 GigabitEthernet0/1/0 - 2

Interface Speed and Duplex Configuration Guidelines

When configuring an interface speed and duplex mode, follow these guidelines:

• If both ends of the line support autonegotiation, we 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.

Command Purpose

Step 1

configure terminal

Example:

Router#configure terminal

Enters global configuration mode.

Step 2

define interface-range macro-name {gigabitethernet

slot/first-interface - last-interface] | vlan vlan-ID - vlan-ID}

Example:

Router(config)#define interface-range first_three

gigabitethernet 0/1/0 - 2

Defines the interface-range macro and saves it in

NVRAM.

Step 3

exit

Example:

Router(config)#exit

Exits global configuration mode.
