Watch Display Summary Calculations
The Watch Results display has been improved and now resembles the Statistics Summary
display. Percentages and totals are now displayed for Transmitted Packets, Transmitted
Payloads, Received and Expected Responses and Received Payloads. RSSI, SQ and RNA
have also been added to the Watch Results display.
Gratuitous ARP
The EUM now transmits a “gratuitous” ARP (an ARP for its own IP address) two seconds after
power up. This gratuitous ARP can be used to determine the IP address of an EUM if it is not
already known. The operator can either sniff the ARP packet on the Ethernet interface, or look
in the ARP table of a connected host.
Network LED Change
The Network LED now flashes slowly during Ethernet-only traffic, instead of being on solid.
EUMID of Duplicate IP Address Packet
The CCU detects packets that are received over the air with the CCU IP address as the
source address. This is considered a “duplicate IP address” and the packet is discarded. The
CCU increments the Routing Protocol statistic Rx Radio Err - Duplicate IP address (Discard).
It also records the EUMID of the EUM from which the packet was received (Last Duplicate IP
from EUMID XX:XX:XX).
Problem Fixes
The following problems were resolved in Version 4.3:
• The RADIUS period is now entered in minutes. Conversion of the previous value from
seconds will occur automatically if it has been changed.
• The size of the Bridge Table has been increased to 1800.
• Telnet no longer truncates very large tables.
• The SNMP MIBII sysName has been changed to LMS3000.
• RADIUS parameters are now reported, whether the client is enabled or not.
• The radio interface MTU is now correctly reported as 1500.
• Rx No Match is now displayed correctly in the CCU statistics summary display.
