Logging into the HTTP Interface

Once the AP has a valid IP Address and an Ethernet connection, you may use your web browser to monitor network statistics.

The Command Line Interface (CLI) also provides a method for viewing network statistics using Telnet or a serial connection. This section covers only use of the HTTP interface. For more information about viewing network statistics with the CLI, refer to Command Line Interface (CLI).

Follow these steps to monitor an AP’s operating statistics using the HTTP interface:

  1. Open a Web browser on a network computer.
  2. The HTTP interface supports the following Web browser:
      • Microsoft Internet Explorer 6 with Service Pack 1 or later
      • Netscape 6.1 or later
  3. If necessary, disable the Internet proxy settings. For Internet Explorer users, follow these steps:
    • Select Tools > Internet Options....
    • Click the Connections tab.
    • Click LAN Settings....
    • If necessary, remove the check mark from the Use a proxy server box.
    • Click OK twice to save your changes and return to Internet Explorer.
  4. Enter the Access Point’s IP address in the browser’s Address field and press Enter.
    • Result: The AP Enter Network Password screen appears.
  5. Enter the HTTP password in the Password field and click OK. Leave the User Name field blank. (By default, the HTTP password is “public”).

This screen displays the following information for each Access Point component:

  • Serial Number: The component’s serial number, if applicable.
  • Component Name
  • ID: The AP identifies a system component based on its ID. Each component has a unique identifier.
  • Variant: Several variants may exist of the same component (for example, a hardware component may have two variants, one with more memory than the other).
  • Version: Specifies the component’s version or build number. The Software Image version is the most useful information on this screen for the typical end user.

Version Information Screen


ICMP

This tab provides statistical information for both received and transmitted messages directed to the AP. Not all ICMP traffic on the network is counted in the ICMP (Internet Control Message Protocol) statistics.

ICMP Monitoring Screen


IP/ARP Table

This tab provides information based on the Address Resolution Protocol (ARP), which relates MAC Address and IP Addresses.

IP/ARP Table


Learn Table

This tab displays information relating to network bridging. It reports the MAC address for each node that the device has learned is on the network and the interface on which the node was detected. There can be up 10,000 entries in the Learn Table.

Learn Table


IAPP

This tab displays statistics relating to client handovers and communications between Avaya Access Points.

IAPP Screen


RADIUS

This tab provides RADIUS authentication, EAP/802.1x authentication, and accounting information for both the Primary and Backup RADIUS servers.

RADIUS authentication and accounting must be enabled for this information to be valid.

RADIUS Monitoring Screen


Interfaces

This tab displays statistics for the Ethernet and wireless interfaces. The Operational Status can be up, down, or testing.

Wireless Interface Monitoring


Link Test

This tab displays information on the quality of the wireless link to clients and other APs in the Wireless Distribution System. During a Link Test, the Access Point and the selected device exchange a series of packets to test the strength of the connection. The devices start by exchanging packets at the 11 Mbits/sec rate but fall back to the slower rates if necessary.

This feature is not available for an 802.11b/g AP. Also, this feature is not available if you are using a non-Avaya client with an 802.11b AP.

Follow these steps to perform a Link Test:

  1. Open the Remote Link Test screen.
  2. Click Explore.

Result: A list of detected stations will appear. If the list does not appear automatically, click Refresh.

Remote Link Test Screen

  1. Select a Station from the list by clicking the circle to the left of the Station’s entry.
  2. Click Link Test to start the test.

Result: A new Link Test window opens and displays the following information for the Access Point (referred to as the Initiator Station) and the wireless client (referred to as the Remote Station):

    • Station Name: The Access Point’s System Name or the client’s Windows Networking name.
    • MAC Address
    • SNR (dB): The Signal to Noise ratio for the received signal. The displayed value is the running average since the start of the test and is reported in decibels (dB). Higher numbers correspond to a stronger link. The bar graph also displays the relative strength of the link (a green bar indicates a strong link, a yellow bar indicates a fair link, and a red bar indicates a weak link).
    • Signal (dBm): The strength of the received signal in dBm (decibels referenced to 1 milliwatt). The displayed value is the running average since the start of the test and is reported as a negative number. Higher numbers correspond to a stronger link. For example, -40 dBm corresponds to a stronger signal than -50 dBm. The bar graph also displays the relative strength of the signal (a longer bar represents a stronger signal).
    • Noise (dBm): The strength of the noise detected at the receiver reported in dBm (decibels referenced to 1 milliwatt). The displayed value is the running average since the start of the test and is reported as a negative number. Noise can interfere with the received signal so a smaller noise value corresponds to a stronger link. For example, a noise level of -95 dBm is more desirable than a noise level of -89 dBm. The bar graph displays the relative strength of the noise level (a shorter bar represents a weaker noise level and is more desirable than a longer bar).
    • 11 Mbps (pkts): The number of packets received at the 11 Mbits/sec transmit rate since the start of the Link Test. In general, most packets will be received at the 11 Mbits/sec rate if the devices have a strong link.
    • 5.5 Mbps (pkts): The number of packets received at the 5.5 Mbits/sec transmit rate since the start of the Link Test.
    • 2 Mbps (pkts): The number of packets received at the 2 Mbits/sec transmit rate since the start of the Link Test.
    • 1 Mbps (pkts): The number of packets received at the 1 Mbits/sec transmit rate since the start of the Link Test.
    • Click the Refresh button periodically to update the test results. The test screen does not refresh automatically.

SNR Report Screen

  1. Click Close to end the Link Test.
