Issue
The Web Applications Alarm tab periodically displays "Cannot Read Alarm Data". The event cannot be acknowledged and continues to show in the list.
Product Line
Power Monitoring Expert (PME) 7.2.x, 8.x
Environment
Web Applications "Alarms"
Cause
Interference from IPv6 local area network adapters enabled on the computer.
Resolution
**NOTE** IPv6 support has been added for version PME 9.0 along with completely new and improved alarm functionalities.
For information on upgrading your system please contact Technical Support.
For PME 7.2.x and PME 8.x:
Disable all IPv6 properties in LAN adapters. This will require confirmation from your network department that this protocol is not being used for any of your other utilities on this server.
1.) Open LAN adapter properties in the Network and Sharing Center.
a.) Go to Start> Control Panel
b.) Click on Network and Sharing Center
c.) On the left select Change adapter settings
d.) Right click all adapters one at a time and select properties
e.) Insure that Internet Protocol Version 6 (TCP/IPv6) is deselected for all adapters.
2.) Disable adapters that are not visible in the Network and Sharing Center
a.) Open a command prompt window
b.) Type ipconfig
c.) Note the listings of adapters available.
d.) Anything listed as ISATAP, TEREDO, or 6to4 must be disabled. Disconnected is not sufficient.
e.) To disable each adapter type the following lines individually and press enter. You should receive an OK if completed correctly.
netsh int ipv6 isatap set state disabled
netsh int ipv6 6to4 set state disabled
netsh interface teredo set state disabled
This should disable IPv6 on the host device and stop the IPv6 stacks from interfering with communication of the software.
~~Notes:
ISATAP (Intra-Site Automatic Tunnel Addressing Protocol) is an IPv6 transition mechanism meant to transmit IPv6 packets between dual-stack nodes on top of an IPv4 network.
In computer networking, Teredo is a transition technology that gives full IPv6 connectivity for IPv6-capable hosts that are on the IPv4 internet but have no native connection to an IPv6 network.
