Configuring the ProCurve Wireless Edge Services xl Module
Management Interfaces
SNMP v3 encrypts management communications. For example, SNMP v3
support secures messages between the Java applet running the Web browser
interface and your management workstation even when you use HTTP rather
than HTTPS.
SNMP Communities. SNMP v1/v2c uses communities to control various
types of management access. In order for an SNMP v1/v2c server to access
the SNMP agent running on a device such as the Wireless Edge Services xl
Module, the server must know at least one of the community names configured
on the device. Each community name is assigned an access control: read-only
or read-write. The access control assigned to the community determines the
operations that an SNMP server can complete on the Wireless Edge Services
xl Module.
A server that knows a device’s read-only community name can view, but not
alter, settings and other information stored on that device. For example, you
might want a particular SNMP server to only monitor traffic on the device. An
SNMP server that knows a device’s read-write community name can change
its configuration in addition to viewing information about it.
The Wireless Edge Services xl Module uses the following community names:
■ public
■ private
■ trap
By default, the public and trap communities have read-only access, and the
private community has read-write access.
For more information on configuring communities, see “SNMP Communities”
on page 2-108. For more information on setting up traps, see “Enabling SNMP
Traps” on page 2-113.
You can also control management access and traps with SNMP v3, as
described in the next section.
SNMP v3 Users.
The management users for the Wireless Edge Services xl
Module are controlled through SNMP v3.
SNMP v3 allows you to create multiple users with different levels of access.
For example, instead of configuring a community name on an SNMP v3 server,
you can configure it with its own username, password, and management
privileges.
