3. Configure the Minimum Packets field to define a minimum packet throughput value for
trap generation.
4. Click Apply to save any changes to the SNMP RF Traps screen. Navigating away from the
screen without clicking the Apply button results in all changes to the screen being lost.
5. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the
settings displayed on SNMP RF Traps screen to the last saved configuration.

4.5 Configuring Network Time Protocol (NTP)
Network Time Protocol (NTP) manages time and/or network clock synchronization in the AP-5131-
managed network environment. NTP is a client/server implementation. The AP-5131 (an NTP client)
periodically synchronizes its clock with a master clock (an NTP server). For example, the AP-5131
resets its clock to 07:04:59 upon reading a time of 07:04:59 from its designated NTP server.
Time synchronization is recommended for the AP-5131’s network operations. For sites using Kerberos
authentication, time synchronization is required.
Use the Date and Time Settings screen to enable NTP and specify the IP addresses and ports of
available NTP servers.
% Dropped Enter a maximum threshold for the total percentage of packets
dropped for each device. Dropped packets can be caused by poor
RF signal or interference on the channel.
% Undecryptable Define a maximum threshold for the total percentage of packets
undecryptable for each device. Undecryptable packets can be the
result of corrupt packets, bad CRC checks or incomplete packets.
Associated MUs Set a maximum threshold for the total number of MUs associated
with each device.
Minimum number of
packets required for a
trap to fire Enter the minimum number of packets that must pass through the
device before an SNMP rate trap is sent. Symbol recommends
using the default setting of 1000 as a minimum setting for the field.
