Rubber Boot Minimum operation time with batteries 6h. GBE loopback device operating at layers L1/L2/元/L4. It is lightweight, rugged design protected with rubber boot, and can operate either with ALBEDO Ether.XX family of tester or any of the industry test and measurements devices. Ether.Loop provides Ethernet loop back for all levels of service testing and monitoring in a compact, battery operated unit that can manage Ethernet frames, IP and TCP/UDP (Layer 1 to 4) at wirespeed operation.Įvery Ethernet frame / IP packet received is inspected and the following parameters are automatically swapped and returned including Source/Destination MAC, IP address, and TCP/UDP ports. It has both a electrical RJ-45 and optical SFP interfaces. All you need in an battery operated Loop-backĮther.Loop is an Ethernet loop-back reflector, flexible and low cost. Is and probably the most cost-effective solution to test end-to-end SLAs. Pairs with ALBEDO testers or any compatible device.
#Loopback device Patch#
I hope HP will come out with a patch for this issue ASAP.Ether-Loop is a battery GbE loopback device that can operate over optical/electrical Loopback devices test a connection for link, data transmission capabilities, or verify if the connection works. The issue should be fixed permanently in the next IMC patch release.įor now I have filtered all duplicate IP alarms out, but as you write, it's not a good solution as I won't see any real IP conflict alarms. When referring to a hardware device, loopback refers to a physical connection that loops either between two devices of the same type, or loops back to itself. However I wouldn't recommend that as you won't get alarms for any duplicate IPs at all anymore. Edit the file, adding the line at the end of the file: Back up $IMC/server/conf/nf to the desktop.ģ. You can also turn duplicate IP alarms off completely if you prefer:Ģ. Note that you should also add an alarm parameter specifically to filter out only 127.0.0.1 alarms, so that you still get alarms for other duplicate IPs across your devices. Virtual network interface that loops back any data sent to it to be immediately received on the same interface. The workaround was posted above to filter the duplicate IP alarms. For us the workaround was to create a trap filter (Alarm -> Trap Management -> Filtering Trap) with the following details: Support told us that this bug will be corrected in a future patch.
Stay tuned and calm with HPE/Aruba Development team anyway Million warning alarms of Device IP Conflict relating to the loopback interface 127.0.0.1, which are very frustrating and hilarious in our NMS at the moment. We all got the same issue with the latest patch E0706H07. Not sure if this is a code flaw or a new "feature"? How would I go about adding an exception for 127.0.0.1? I've never seen this one triggered like this before.
#Loopback device software#
Interface InLoopBack0 of device at 10.2.0.212 and interface HP ProCurve Switch software loopback interface of device at 10.3.0.208 have a conflicting IP address 127.0.0.1.
#Loopback device upgrade#
I just upgrade from E0705 to E0706P06 and I'm getting warnings from every device in my network: Saw the error as you mentioned and it wasn't there in E0705P12 Just updated and did the log4j disable in startup.bat.
