Configuring Basic Parameters
Configure Global Parameters
Perform these steps to configure selected global parameters for your router:
For complete information on the global parameter commands, see the Cisco IOS Release 12.3
documentation set.
Configure Fast Ethernet LAN Interfaces
The Fast Ethernet LAN interfaces on your router are automatically configured as part of the default
VLAN and as such, they are not configured with individual addresses. Access is afforded through the
VLAN. You may assign the interfaces to other VLANs if desired. For more information about creating
VLANs, see
Chapter 5, “Configuring a LAN with DHCP and VLANs.”
Configure WAN Interfaces
The Cisco Secure Router 520 Ethernet-to-Ethernet routers have one Fast Ethernet interface for WAN
connection. The Cisco Secure Router 520 ADSL-over-POTS and Cisco Secure Router 520
ADSL-over-ISDN routers have one ATM interface for WAN connection.
