Why so high Ping Latencies in VE LTM ?
Hello, I'm evaluating a VE LTM Trial, 25 Mbps, BIG-IP 12.1.1 Build 2.0.204 Hotfix HF2 It's running on Hyper-V on Windows Server 2012R2. When I run ping from the Hyper-V console window of the LTM VM I can measure the following times: ping -I 172.27.50.1 172.27.50.151 = **7 ms .. 30 ms** (pinging from the LTM internal static self-IP to another VM attached to the same Virtual Switch) ping -I 172.27.50.1 172.27.50.161 = **7 ms .. 30 ms** (pinging from the LTM internal static self-IP to another VM reached through the external network, through a physical switch) ping -I 172.27.50.1 172.27.51.1 < 1 ms (pinging from the LTM internal static self-IP to the LTM external static self-IP) ping -I 172.27.50.1 172.27.52.1 < 1 ms (pinging from the LTM internal static self-IP to the LTM management address) ping -I 172.27.50.1 172.27.51.51 = **2 ms .. 4 ms** (pinging from the LTM internal static self-IP to any of the configured LTM Virtual Servers) pings between the two devices over the HA VLAN are even higher: tens of ms ! I reserved what I judge to be the recommended amounts of vCPU and memory to the LTM VE. I have also disable Virtual Machine Queues in the PhyNICs and in the LTM VNICs. Has someone suggestions of configurations to check/change, or troubleshooting procedures to reveal the cause of the high latencies above ? Many thanks!
"Managed by BIG-IQ" message not removed from BIG IP LTM
I have added BIG-IP LTM device in BIG-IQ and now wanted to add this device to other BIG-IQ but it is not allowing this. when I removed the device from BIG-IQ system, it is no more reflecting in BIG-IQ, however on the LTM GUI top left it is still showing as "Managed by BIG-IQ". when I click on "Managed by BIG-IQ", it opens the same old BIG-IQ, however the device removed from there.
