Installing the Access Point in the Network

Figure 1-1 Cisco Aironet 1810 Series OfficeExtend AP Network Deployment Overview

Note In some cases your broadband modem may have an integrated router capability and therefore you do not

require a separate router placed between the broadband modem and the Cisco Aironet 1810 Series OfficeExtend Access Point.

To install the Cisco Aironet 1810 Series OfficeExtend AP, follow these steps:

Step 1 Insert one end of the Ethernet cable into the Ethernet port of your home router/gateway and the other end

into the LAN port of the AP.

Step 2 Power up the AP.

While the AP boots up the status LED blinks green. After association with the controller, the LED changes to chirping green, When a wireless client associates with the AP, the LED stays green.

For information on the status LED indications, see the Getting Started Guide.

Step 3 If your IT administrator has not pre-provisioned the 1810 Series Office Extend AP with the IP address

of the Wireless Controller, continue with the following steps.

Step 4 Obtain the IP address of your Wireless LAN Controller from your company’s IT professional.

Step 5 Connect your laptop to the Console port of the access point.

Step 6 Open an Internet browser and go to the IP address of the access point. The default IP address is 10.0.0.1

Note Make sure your laptop is not connected to your company’s network using a virtual private

network (VPN) connection.

Step 7 At the OfficeExtend Access Point login window, click Login, and then enter the username and password

to log into the access point. The default username and password are admin and admin.

Chapter 1 Installing and Configuring the Access Point

The AP connects to the controller and downloads the current software image. Allow 5 minutes for the device to download and reboot with the new code and configuration.

Note The AP restarts when any change is applied on local the GUI. For example, changing the settings

for the personal SSID causes interruption to the corporate SSID. It recovers only after the AP rejoins the controller.

Note You do not need to configure any SSIDs for your AP to connect to your company network. The

access point receives the company SSID when it connects to the company network by way of the Internet. If you have problems connecting to your company network, contact your IT administrator. You can configure your local SSID WLAN for other devices. See the“Configuring

Radio Channels on the Access Point” section on page 1-4.

Note Cisco Aironet 1810 Series OfficeExtend access points are designed to work behind a router or

other gateway device that is using network address translation (NAT). NAT allows a device, such as a home router or gateway, to act as an agent between the Internet (public) and a personal network (private), thereby enabling an entire group of computers to be represented by a single IP address. There is not limit to the number of Cisco Aironet 1810 Series OfficeExtend access points that can be deployed behind a single NAT device.

• Set the rule for all LAN clients or only for clients in a specified IP address range.

–

To set the rule for all local clients, check the All Clients check box.

–

To set the rule for a range of IP address, specify the Local IP Address Range.

• Set the rule to filter access to applications using the any of the following protocols:

–

FTP

–

Telnet

–

SMTP

–

DNS

–

TFTP

–

HTTP

–

POP3

–

NNTP

Configuration Page

Port Forwarding

Chapter 2 Understanding the Access Point GUI

–

SNMP

–

HTTPS

Select the required protocol for the rule by choosing it from the Protocol drop-down list.

• Set the rule to filter the traffic to specified destination port range, or to TCP or UDP ports as a whole.

Depending on your requirement, you can use the Destination Port Range fields, or select TCP or UDP from the Protocol drop-down list.

• Set the rule as an allow or disallow rule for the combination of the aforementioned parameters.

Check the Allow check box to make this an allow rule. Else, uncheck it.

The Port Forwarding settings allow you to configure port forwarding rules for packets from WAN port to Local LAN clients and back. A maximum of 10 Port Forwards can be set, but their ranges should be of the same size and should not overlap. For each rule you can set the following parameters:

• Protocol—You select either of the following options as per your requirements:

–

Select TCP or UDP and then set the WA N Po r t S ta r t and WA N Po rt E nd values.

DMZ

–

Select one of these protocols— FTP, Telnet, SMTP, DNS, TFTP, HTTP, POP3, NNTP, SNMP, or HTTPS

• WAN port range—You can manually set this, using the WAN Po rt St a rt and WA N Po rt En d fields,

only if the protocol is specified as TCP or UDP. For all other protocols this range displays the pre-configured port number.

• Local IP address—Specify the Local LAN client IP Address where the traffic is to be forwarded to.

• LAN port range—Set this range using the Local Port Start and Local Port End fields.

The DMZ feature allows one network computer connected to a local LAN or WLAN to be exposed to the Internet for using special-purpose services such as Internet gaming. The DMZ feature forwards all the ports terminating on a WAN IP, which is set as the DMZ IP Address, at the same time to one PC.

The DMZ feature, if enabled, will forward all incoming WAN packets to the LAN machine, except the CAPWAP control/data and packets which are destined to any ports and which have a port forwarding rule. The DMZ feature is not applicable to corporate networks such as Remote-LAN and Corp WLAN.

However, the Port Forwarding feature is more secure, compared to DMZ feature because the former only opens the ports you want to have opened, while DMZ opens all the ports of one computer, exposing the computer to the Internet/WAN.

Network Diagnostics

The functionalities of the Network Diagnostics tab are as follows:

• Speed Test—The Speed test feature calculates both the download and upload speeds (DTLS and

non-DTLS) between the controller and the AP. It provides the network speed with DTLS and Non-DTLS connections. Using the Speed Test feature you can determine the non-DTLS throughput of the system, by running a speed test on demand. This allows for root cause failure analysis and debugging of network bottlenecks.

• Link Test—The Link test provides the link latency and the jitter values. Link latency monitors the

round-trip time of the CAPWAP packets (echo request and response) from the access point to the controller. The round-trip time is calculated in milliseconds. The jitter value is then calculated using the link latency values. Jitter is the amount of variation in latency/response time, in milliseconds.

• Network Diagnostics Last Run—Shows the details of the last run diagnostics along with its

timestamp.

Note You can run the Speed and Link tests from the AP’s GUI, the controller’s GUI, and the controller’s CLI.
