Programmable SNMP v1/v2/v3 Trap Support
Simple Network Management Protocol (SNMP) facilitates the exchange of management information
between network devices. SNMP uses Management Information Bases (MIBs) to manage the device
configuration and monitor Internet devices in remote locations. MIB information accessed via SNMP is
defined by a set of managed objects called Object Identifiers (OIDs). An object identifier (OID) is used to
uniquely identify each object variable of a MIB.
SNMP allows a network administrator to configure the access point, manage network performance, find
and solve network problems, and plan for network growth. The access point supports SNMP
management functions for gathering information from its network components. The access point’s
download site contains the following 2 MIB files:
● EXTR-CC-adp35xx-MIB-2.0 (standard/common MIB file)
● EXTR-adp35xx-MIB (Altitude 35xx specific MIB file)
The access point’s SNMP agent functions as a command responder and is a multilingual agent
responding to SNMPv1, v2c and v3 managers (command generators). The factory default configuration
maintains SNMPv1/2c support of community names, thus providing backward compatibility.
For detailed information on configuring SNMP traps, see “Configuring SNMP Settings” on page 86.
Power-over-Ethernet Support
When users purchase an Extreme Networks WLAN solution, they often need to place access points in
obscure locations. In the past, a dedicated power source was required for each access point in addition
to the Ethernet infrastructure. This often required an electrical contractor to install power drops at each
access point location.
The Altitude 3550 Power Tap is also a single-port, 802.3af compliant Power over Ethernet hub
combining low-voltage DC with Ethernet data in a single cable connecting to the access point. However,
the Power Tap is designed and ruggedized for use with an Altitude 3550’s outdoor deployment. For
detailed information on using the Power Tap, see “Power Tap Systems” on page 40.
MU-MU Transmission Disallow
The access point’s MU-MU Disallow feature prohibits MUs from communicating with each other even if
on the same WLAN, assuming one WLAN is configured to disallow MU-MU communication.
Therefore, if an MU’s WLAN is configured for MU-MU disallow, it will not be able to communicate
with any other MUs connected to this access point.
For detailed information on configuring an Altitude 35xx WLAN to disallow MU to MU
communications, see “Creating/Editing Individual WLANs” on page 135.
Voice Prioritization
Each Altitude 35xx access point WLAN has the capability of having its QoS policy configured to
prioritize the network traffic requirements for associated MUs. A WLAN QoS page is available for each
enabled WLAN on both the 802.11a and 802.11b/g radio.
Use the QoS page to enable voice prioritization for devices to receive the transmission priority they may
not normally receive over other data traffic. Voice prioritization allows the access point to assign
