2-3 Book Title OL-xxxxx-xx Chapter 2 Wireless Device Overview Management Options Central Unit in an All-Wireless Network In an all-wireless network, an access point acts as a stand-alone root unit. The access point is not attached to a wired LAN; it functions as a hub linking all stations together. The access point serves as the focal point for communications, increasing the communication range of wireless users. Figure 2-2 shows an access point in an all-wireless network.

3-2 Cisco 860 and Cisco 880 Series Integrated Services Routers Software Configuration Guide OL-xxxxx-xx Chapter 3 Basic Router Configuration Interface Ports NoteIndividual router models may not support every feature described in this guide. Features that are not supported by a particular router are indicated whenever possible. This chapter includes configuration examples and verification steps, as available. For complete information on how to access global configuration mode, see the “Entering Global Configuration Mode” section in Appendix A, “Cisco IOS Basic Skills.” For more information on the commands used in the following tables, see the Cisco IOS Release 12.4(15)XZ documentation set. Interface Ports Ta b l e 3-1 lists the interfaces that are supported for each router and their associated port labels on the equipment. Default Configuration When you first boot up your Cisco router, some basic configuration has already been performed. All of the LAN and WAN interfaces have been created, console and vty ports are configured, and the inside interface for Network Address Translation (NAT)has been assigned. Use the show running-config command to view the initial configuration, as shown in the following example.

These PVC parameters are typically virtual path identifier (VPI), virtual circuit identifier (VCI), and traffic-shaping parameters. –Determine the number of PVCs that your service provider has given you, along with their VPIs and VCIs. –For each PVC determine the type of AAL5 encapsulation supported. It can be one of the following: AAL5SNAP—This can be either routed RFC 1483 or bridged RFC 1483. For routed RFC 1483, the service provider must provide you with a static IP address. For bridged RFC 1483, you may use DHCP to obtain your IP address, or you may obtain a static IP address from your service provider.
3-5 Cisco 860 and Cisco 880 Series Integrated Services Routers Software Configuration Guide OL-xxxxx-xx Chapter 3 Basic Router Configuration Configuring Basic Parameters AAL5MUX PPP—With this type of encapsulation, you need to determine the PPP-related configuration items. If you plan to connect over an ADSL or G.SHDSL line: –Order the appropriate line from your public telephone service provider. For ADSL lines—Ensure that the ADSL signaling type is DMT (also known as ANSI T1.413) or DMT Issue 2. For G.SHDSL lines—Verify that the G.SHDSL line conforms to the ITU G.991.2 standard and supports Annex A (North America) or Annex B (Europe). Once you have collected the appropriate information, you can perform a full configuration on your router, beginning with the tasks in the “Configuring Basic Parameters” section on page 3-5. If you plan to connect voice equipment: –Seethe Cisco IOS Voice Port Configuration Guide If you plan to install 3G backup: –See Chapter 5, “Configuring Backup Data Lines and Remote Management” To obtain or change software licenses: –See Software Activation on Cisco Integrated Routers Configuring Basic Parameters To configure the router, perform one or more of these tasks: Configuring Global Parameters Configuring the Fast Ethernet LAN Interfaces Configuring WAN Interfaces Configuring a Wireless Interface Configuring a Loopback Interface Configuring Command-Line Access A configuration example is presented after each task to show the network configuration.
3-6 Cisco 860 and Cisco 880 Series Integrated Services Routers Software Configuration Guide OL-xxxxx-xx Chapter 3 Basic Router Configuration Configuring Basic Parameters Configuring Global Parameters To configure selected global parameters for your router, perform these steps: For complete information on the global parameter commands, see the Cisco IOS Release 12.4(15)XZ documentation set. Configuring the Fast Ethernet LAN Interfaces The Fast Ethernet LAN interfaces on your router are automatically configured as part of the default VLAN and are not configured with individual addresses. Access is provided through the VLAN. You may assign the interfaces to other VLANs if you want. For more information about creating VLANs, see Chapter 7, “Configuring the Ethernet Switches.” Configuring WAN Interfaces The Cisco 860 and Cisco 880 series ISRs each have one interface for a WAN connection. Configure the WAN interface for your router using one of the following as appropriate: CommandPurpose Step 1configure terminal Example: Router> enable Router# configure terminal Router(config)# Enters global configuration mode, when using the console port. If you are connecting to the router using a remote terminal, use the following: telnet router name or addressLogin: login id Password: ********* Router> enable Step 2hostname name Example: Router(config)# hostname Router Router(config)# Specifies the name for the router. Step 3enable secret password Example: Router(config)# enable secret cr1ny5hoRouter(config)# Specifies an encrypted password to prevent unauthorized access to the router. Step 4no ip domain-lookup Example: Router(config)# no ip domain-lookup Router(config)# Disables the router from translating unfamiliar words (typos) into IP addresses.

Step 5Router(config-ctrl)# line-rate 4608Specifies the DSL line rate for the SHDSL port. The range is 192 to 2312 kb/s. The default is auto (negotiated between the SHDSL port and the DSLAM). NoteIf different DSL line rates are configured at opposite ends of the DSL uplink, the actual DSL line rate is always the lower rate. NoteThe maximum peak cell rate is 8 kb/s less than the line rate. Step 6Router(config-ctrl)# interface atm0Enters ATM configuration mode for interface ATM 0. Step 7Router(config-ctrl)#ip-address IP-address Assigns an IP address to the DSL ATM interface. Step 8Router(config-ctrl)#load-interval 3 Step 9Router(config-ctrl)# no atm ilmi-keepalive0(Optional) Disables Integrated Local Management Interface (ILMI) keepalives. If you enable ILMI keepalives without specifying the number of seconds, the default time interval is 3 seconds. Step 10Router(config-ctrl)# pvc 0/35Enters atm-virtual-circuit (interface-atm-vc) configuration mode, and configures a new ATM PVC by assigning a name (optional) and VPI/VCI numbers. The default traffic shaping is UBR; the default encapsulation is AAL5+LLC/SNAP. Command Purpose
