Cisco HWIC-4ESW and HWIC-D-9ESW EtherSwitch Interface Cards How to Configure EtherSwitch HWICs DETAILED STEPS Command or Action Step 1 enable Step 2 Example: Router> enable configure terminal Purpose Enables privileged EXEC mode. • Enter your password if prompted. Enters global configuration mode. Step 3 Example: Router# configure terminal define interface-range macro-name {fastethernet interface-id [ - interface-id] | {vlan vlan-id - vlan-id} | [, fastethernet interface-id [ interface-id] Defines a range of macros. • Enter the macro name, along with the interface type and interface number, as appropriate. Example: Router(config)# define interface-range first_three FastEthernet0/1/0 - 2 Configuring Layer 2 Optional Interface Features This section provides the following configuration information: • Configuring the Interface Speed, page 12 (optional) • Configuring the Interface Duplex Mode, page 13 (optional) • Configuring a Description for an Interface, page 14 (optional) • Configuring a Description for an Interface, page 14 (optional) • Configuring a Fast Ethernet Interface as a Layer 2 Trunk, page 15 (optional) • Configuring a Fast Ethernet Interface as Layer 2 Access, page 17 (optional) Configuring the Interface Speed Use the following task to set the interface speed. When configuring an interface speed, 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 interface 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 might shut down and reenable the interface during the reconfiguration. SUMMARY STEPS 1. enable 13
