Updatable Firmware
Extreme Networks periodically releases updated versions of device firmware to the Extreme Networks
Web site. If the firmware version displayed on the System Settings page (see
“Configuring System
Settings” on page 68 ) is older than the version on the Web site, Extreme Networks recommends
updating the access point to the latest firmware version for full feature functionality.
For detailed information on updating the Altitude 35xx firmware using FTP or TFTP, see “Updating
Device Firmware” on page 107 .
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.
