Extreme Networks Evaluation Guide

This document will describe the industrial design and

modularity, and provide step-by-step conﬁgurations for

typical use cases in multi-tenant markets such as hotels.

The glossary of features lists the webUI screens, along

with a short description of the functionality. The high-

powered radio will need to be tested by comparing the

Altitude™ 4511 with other, “known” access points. When the

comparison is made, the value of the Altitude 4511 will

become more apparent.

Evaluation Guide

Extreme Networks Evaluation Guide: Altitude 4511 Access Point

The Extreme Networks Altitude 4511 Access Point can

change the way wireless networks are installed, while

lowering the deployment and operations expense

associated with a wireless network.

When evaluating the Altitude 4511, take note of these

three key features and their cost saving advantages:

Advanced Industrial Design –

“Hide-in-Plain-Sight”

The Altitude 4511 access point installs in minutes

anywhere a CAT 5/6 cable is located. Due to its tiny size,

the Altitude 4511 will hide in plain sight; ceiling mount,

tabletop, or wall surface. A patent-pending mechanical

design is optimized for installation over any structured

wiring CAT 5/6 wall jack. The wallplate form factor is

25mm (1 inch) thick, and ﬂush mounted to the wall

surface. The AP does not protrude into the wall cavity.

This design allows for ecient heat transfer and a

universal installation over any structured wiring plate.

The modular design allows the end-user to add switched

Ethernet ports as needed, and snap in any keystone or

Leviton QuickPort® style connector to the wallplate.

High-Powered 802.11a/b/g/n Radio

Under the sleek exterior, the Altitude 4511 packs a 26dBm

transmitter along with dual omni-directional 3dBi peak

gain antennas. The AP supports either 2.4Ghz or 5.2Ghz

operating bands. 2x2 multiple-input and multiple-output

(MIMO) technology and support for legacy 802.11a/b/g is

ideal for supporting a wide range of laptops, portable

media players, tablets, mobile computers, Wi-Fi phones

and wireless enabled smartphones.

Controller AP

The Altitude 4511 can be managed via CLI or webUI as a

standalone access point. When more than one AP is

installed, any single Altitude 4511 can operate as a

Controller AP for a network of up to 25 Altitude 4511s. By

using the hardware of an access point to run controller

features, the Altitude 4511 dramatically lowers the cost of

a managed, RF controller-based network for small

hotels. All the features you want from an RF controller

are here; ﬁrmware management, central conﬁguration,

status and statistics. Also advanced features such as fast

roaming, Smart RF, and Rogue AP detection are all

included in the Controller AP function.

Scope of this Document

This document will describe the industrial design and

modularity, and provide step by step conﬁgurations for

typical use cases in multi-tenant markets such as hotels.

The glossary of features lists the webUI screens, along

with a short description of the functionality. The high

powered radio will need to be tested by comparing the

Altitude 4511 with other, “known” access points. When

the comparison is made, the value of the Altitude 4511

will become more apparent.

Use Case 1: Conﬁgure a single AP as a standalone AP

using the conﬁguration overrides.

Use Case 2: Use the Initial Setup Wizard to conﬁgure a

Controller AP and dependent APs with one WLAN.

Use Case 3: Use the conﬁguration screens to conﬁgure a

Controller AP with two WLANs; one open and one

secure. VLANs will be added to WLANs and switched

Ethernet ports.

Keystone Connector

The snap-in port is designed to accept any keystone-

style or Leviton QuickPort® connector. These connectors

are a popular mechanical form factor for RJ-11, RJ-45,

F-connector and many more network and communica-

tions connectors.

Snap out the blanking plug on the wallplate and snap in

the connector of your choice. The latch on the keystone

connector should always face toward the top of the AP.

One-Port RJ-45 Ethernet Module

The keystone port also accepts a one-port RJ-45 Ethernet

Module. This module is supplied in the shipping box with a

pigtail connector terminating in a 9-pin header. Snap in

the RJ-45 connector and connect the header pin to the

matching header on the back of the unit, labeled “FE1”

Vital Information Before

We Begin

Power

The Altitude 4511 requires Power over Ethernet. Connect

an 802.3af PoE switch or PoE midspan injector to the

port labeled UP1/PoE on the back of the unit. The AP

will draw between 6.5W and 9W of power depending on

the number of Ethernet ports connected and the trans-

mission speed.

The AP takes three minutes to completely boot up. At two

minutes, the Web server is active and will respond to a

Web browser. However, the backend database will not

authenticate user login for another minute.

The Altitude 4511 can be accessed from a webUI or CLI.

This guide will use the webUI login.

The webUI requires the Adobe Systems ﬂash plugin. If it is

not installed, the webUI will prompt the administrator to

install ﬂash.

For instructions on upgrading the system ﬁrmware, see

the Appendix.

Default user name: admin

Default password: admin123

Default IP address: IP address assigned by DHCP client, or

zero-conﬁg IP address where the last two octets in the IP

address are the decimal equivalent of the last two bytes in

the MAC address.

Example: MAC address 00:C0:23:00:F0:0A

Zero-conﬁg IP address: 169.254.240.10

To use the zero-conﬁg IP address, manually set your PC to

same IP subnet. See the Appendix for further assistance

converting the MAC bytes in hex to its decimal equivalent.

After the ﬁrst login following a factory default conﬁgura-

tion, the administrator will be prompted to change the

password.

Controller AP

A Controller AP is any single Altitude 4511 that is conﬁg-

ured to operate as an RF controller. The Controller AP

provides a necessary set of management features

required for a small facility. Key features of the Controller

AP include:

• Automatic adoption of dependent APs

• Central conﬁguration for all APs

• Firmware upgrade on all APs

• One IP address for the network management. The

dependent APs are managed via a secure Layer 2

protocol. IP addresses can be assigned to depen-

dent APs if desired

• Central status and statistics for APs and connected

wireless clients

• IPS/IDS for rogue AP detection

• SmartRF for ecient spectrum management

and redundancy

– Automatic channel selection

– Automatic transmit power adjustment

– Neighbor AP recovery

• Fast roaming for mobile devices

• Role-based client access

• Layer 2 and Layer 3 access control

By default, an AP will be dependent if a Controller exists

in the network. Adoption is automatic.

A dependent AP obtains its conﬁguration from a proﬁle

stored on the Controller AP. Any manual conﬁguration

changes on a dependent AP will be overwritten by the

Controller upon reboot. Up to 24 dependent APs can be

connected to a Controller AP.

Extreme Networks Evaluation Guide: Altitude 4511 Access Point

Initial Setup Wizard

The Wizard will run automatically after a factory reset. It

will walk the administrator through a set of minimum

required conﬁgurations. Once complete, proﬁles will be

created and assigned to the device. To restart the

Wizard, you must reset the unit to factory defaults. See

the Appendix for instructions on resetting the factory

default conﬁguration.

The conﬁguration screens in the Setup Wizard include:

Operating Mode: Standalone AP; Controller AP;

Dependent AP

Basic System Info: Password, Timezone, Country,

Network Access

VLAN and IP Address: Set the native VLAN and member

VLANs for all interfaces. Set whether the interface is an

access or trunk port. Assign the IP address to the uplink

LAN port.

WLAN Conﬁguration: Set up multiple WLANs and set

the minimum required information such as SSID,

Authentication, and VLAN. If needed, set up a RADIUS

server to authenticate a WLAN.

Policies, Proﬁles and Adoptions

Policies

Most (but not all) conﬁguration elements such as

Firewall and WLAN are conﬁgured as a policy. Multiple

policies can be created and edited. Once a policy is

created, it must be mapped onto a device proﬁle. If a

policy is edited, those edited changes are automatically

applied to any device mapped to that policy.

Note that there are policies inside of policies. For

example, Wireless Clients can be allowed or denied

access to the network based on an IP or MAC ﬁrewall

policy. Thus, the Wireless Client Roles policy requires a

Firewall policy.

Policies can be created at any time. When the adminis-

trator is presented with a drop down box to select a

policy, there will always be a “create” and “edit” button

to allow the additional policy to be created at that time.

To keep the conﬁguration steps clear, we recommend

creating a core set of policies at the beginning. Thus,

these policies will be ready for selection when the device

proﬁles are created.

Device Proﬁles

Device Proﬁles are a container for policies and other

conﬁgurations, and are assigned to devices either

manually or by an adoption policy. Device proﬁles should

be created for major groups of devices. For example, a

typical network would have at least two proﬁles; one

proﬁle for the Controller AP, and one proﬁle for all

dependent APs. If APs will service distinct areas of a

hotel; such as guest rooms and meeting rooms, then a

unique dependent AP proﬁle may be created for each of

these unique applications.

Device Overrides

Note that any proﬁle conﬁguration can be overridden by

speciﬁcally conﬁguring the device. It is recommended

that device overrides be used at a minimum. Commonly,

a device override is used to assign the management IP

address and default gateway to a Controller AP. Another

use for device overrides is to quickly conﬁgure a

standalone AP. If a device conﬁguration is overridden, be

certain to document the conﬁguration to prevent

confusion later.

Extreme Networks Evaluation Guide: Altitude 4511 Access Point

Adoption

Dependent APs are adopted by a Controller AP. By default, each AP is standalone or dependent. When a new AP is

installed in the network, it will begin the network discovery process to ﬁnd a Controller AP. On the Controller AP, an

adoption policy can be created to control which APs are adopted. The policy rules can include MAC address, serial

number, DHCP option, and other parameters.

Policies Available for Conﬁguration

Refer to the Appendix for a description of each of these policies. The core policies that will always be conﬁgured are

shown in green. Note that there are policies inside of policies. Also, some policies, notably ﬁrewall policies, can be

selected in multiple screens.

TIP

Conﬁgure Policies ﬁrst then map policies to Device Proﬁles.

In a simple network, edit the “default” policy to match your requirements rather than create new policies.
