AP-5131 Introduction
1-15
SNMP allows a network administrator to configure the AP-5131, manage network performance, find
and solve network problems, and plan for network growth. The AP-5131 supports SNMP management
functions for gathering information from its network components. The AP-5131 CDROM and the (AP-
5131 downloads site) contains the following 2 MIB files:
• Symbol-CC-WS2000-MIB-2.0 (standard Symbol MIB file)
• Symbol-AP-5131-MIB (AP-5131 specific MIB file)
The AP-5131 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 the community names, hence providing backward compatibility.
For detailed information on configuring SNMP traps, see Configuring SNMP Settings on page 4-17.
1.2.13 Power-over-Ethernet Support
When users purchase a Symbol 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.
An approved power injector solution merges power and Ethernet into one cable, reducing the burden
of installation and allows optimal AP-5131 placement in respect to the intended radio coverage area.
The AP-5131 can only use a Power-over-Ethernet device when connected to the LAN port.
The Symbol Power Injector (Part No. AP-PSBIAS-T-1P-AF) is a single-port, 802.3af compliant Power
over Ethernet hub combining low-voltage DC with Ethernet data in a single cable connecting to the
AP-5131. The Power Injector’s single DC and Ethernet data cable creates a modified Ethernet cabling
environment on the AP-5131’s LAN port eliminating the need for separate Ethernet and power cables.
For detailed information on using the Symbol Power Injector, see Symbol Power Injector System on
page 2-8.
1.2.14 MU-MU Transmission Disallow
The AP-5131’s MU-MU Disallow feature prohibits MUs from communicating with each other even if
they are on different WLANs, assuming one of the WLAN’s 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 AP-5131.
For detailed information on configuring an AP-5131 WLAN to disallow MU to MU communications,
see Creating/Editing Individual WLANs on page 5-24.
