Nimbostratusthe Graph in the dashboard has a 30.5mb as peak over a week, hardly any traffic. Some new findings 1. When i do a tcpdump to capture all traffic from and to the server and while doing a file transfer i can see there is a 30 sec pause at one stage which doesnt have any traffic for that node on the F5. 2. I tried do a continuous ping with packet size set to 1500 and that failed straight away. I found that the max value i could use for the packet size was 1454 anything above that fails even when the node is pinging its own gateway on the f5. I have checked the F5 vlan settings and the mtu is 1500. so i would assume this should just work. 3. I have verified ESXi server and the Switch MTU Size which are default and a VM in the ESXi host can ping the switch with packet size 1500. So this is def not relating to the Cisco Switch etc.
I am leaning towards the large packet size causing this issue. Any ideas?
