Management and Monitoring Capabilities
To configure the 520wl for your needs, set your specific network, wireless interface, and bridge parameters. The HTTP
(web browser) Interface provides easy configuration and management.
Wireless clients (computers connected to your network through wireless access) use configuration software for
network access. Once connected, users can roam from one coverage cell to another while maintaining their
connection.
There are four management and monitoring interfaces available to the network administrator to configure and manage
the 520wl unit(s) in the network:
1. HTTP/HTTPS Interface
2. Command Line Interface
3. Full SNMP configuration capabilities
4. SNMPv3 Secure Management
HTTP/HTTPS Interface
The HTTP Interface (Web browser Interface) provides easy access to configuration settings and network statistics
from any computer in the network. Use the HTTP Interface through your LAN (switch, hub, and so forth), through the
Internet, or with a crossover Ethernet cable connected directly to your computer’s Ethernet Port.
HTTPS provides an HTTP connection over a Secure Socket Layer. HTTPS is one of two available secure
management options on the AP; the other secure management option is SNMPv3. Enabling HTTPS allows the user to
access the AP in a secure fashion using Secure Socket Layer (SSL) over port 443. The AP supports SSLv3 with a
128-bit encryption certificate maintained by the AP for secure communications between the AP and the HTTP client.
All communications are encrypted using the server and the client-side certificate.
The AP comes with all required SSL files: default certificate, private key and SSL Certificate Passphrase, installed.
Command Line Interface
The Command Line Interface (CLI) represents a set of keyboard commands and parameters used for configuring and
managing the 520wl.
Users enter Command Statements, composed of CLI Commands and their associated parameters. Statements may
be issued from the keyboard for real time control, or from scripts that automate configuration. For example, when
downloading a file, administrators enter the
download
CLI Command along with IP Address, file name, and file type
parameters.
Q
If necessary, use the CLI with your computer serial port to initialize the proper IP address for your network.
Q
The CLI provides configuration and management access for most generic Telnet and Terminal clients. Use the CLI
through your computer serial port, over your LAN, through the Internet, or with a crossover Ethernet cable
connected directly to your computer.
Details of the CLI commands used to manage the 520wl device along with syntax and specific parameters names can
be found in “
SNMP Management
In addition to the HTTP and the CLI interfaces, you can also manage and configure a 520wl using the Simple Network
Management Protocol (SNMP). This requires an SNMP manager program, like HP Openview or Castlerock’s SNMPc.
The 520wl supports several Management Information Base (MIB) files that describe the parameters that can be
viewed and/or configured over SNMP:
Q
MIB-II (RFC 1213)
Q
Bridge MIB (RFC 1493)
Q
Ethernet-like MIB (RFC 1643)
Q
802.11 MIB
Q
Enterprise MIB
HP provides these MIB files on the 520wl CD and through the HP ProCurve website at
http://www.hp.com/go/hpprocurve
. You need to compile one or more of the above MIBs into your SNMP program’s
database before you can manage the 520wl. Refer to the documentation that came with your SNMP manager for
instructions on how to compile MIBs.
The Enterprise MIB defines the read and read-write objects that can be viewed or configured using SNMP. These
objects correspond to most of the settings and statistics that are available with the other management interfaces. Refer
to the Enterprise MIB for more information; the MIB can be opened with any text editor, such as Microsoft Word or
WordPad.
