Extreme Networks Evaluation Guide: Altitude 4511 Access Point
© 2011 Extreme Networks, Inc. All rights reserved.
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.

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.
Login
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.

Use the Operations menu to reload firmware, restart, or view the running configuration. Navigate to Operations ->
Devices. Select the action from the list at the bottom of the page.
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.

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.

Network View
The Dashboard view provides quick status of the
network and clients. One key feature of the Dashboard is
the Network View where the administrator can color
code the wireless clients using quality indicators.
The indicators are RF Quality, Utilization, SNR, and
Threat. For each indicator, a filter can be applied with
Low, Medium, and High thresholds.
Use the Dashboard Network View to quickly gauge the
status of the wireless clients and identify if corrective
action is needed.
Double click on a client to see detailed statistics about
the connection.
