SNMP
The Harmony 802.11a Access Point supports SNMP version 2c (SNMPv2c) and a
subset of the following Management Information Base (MIB) files:
• System Group, Interface Group, and IP Group of MIB-II (RFC 1213)
• Ethernet-like MIB (RFC 1643)
• IEEE 802.11 MIB
These MIBs describe the 802.11a AP parameters and statistics that can be viewed
and/or configured over SNMP. You may need to compile one or more of the above
MIBs into your SNMP program’s database before you can manage the Access Point
over SNMP. Refer to the documentation that came with your SNMP manager for
instructions on how to compile MIBs. The MIBs are available for download on
Proxim’s Web site.

SNMP Supported Traps
A device that is managed via SNMP occasionally sends unsolicited messages to the
SNMP manager; these messages are known as Trap-PDUs (Protocol Data Units) or
traps. A trap is typically generated in response to a specific event. For example,
during boot up, an SNMP-managed device sends a Cold Start trap to the SNMP
manager.
The following traps are supported by the Harmony 802.11a Access Point and are sent
to the configured Trap Destination IP Address when they occur:
•
Cold Start
: An Access Point generates this trap when the unit is powered on or
rebooted and its configuration may have been altered.
•
Warm Start:
An Access Point generates this trap when the unit is rebooted and its
configuration has not been altered.
•
Link Up/Wireless Station Association
: An Access Point generates this trap each
time a wireless Station associates with it.
•
Link Down/Wireless Station Disassociation
: An Access Point generates this trap
each time an association with a wireless Station is terminated.
SNMP Configuration
You can configure the following SNMP settings for the Harmony 802.11a Access Point:
•
Use SNMP
: Set this parameter to
Yes
to enable SNMP management. When
enabled, additional options appear on the Network Configuration screen.
•
Read-Only Community
: This parameter specifies a community supported by the
Access Point. Actions permitted by this community are read-only (GET and
GET-NEXT). SET attempts using this community will result in rejection of the
attempt with a general error response. By default, this community is set to
“public.”
