NimbostratusF5 VE latency and sync issues
We recently moved our two F5 VE Lab appliances from an older VMware 5.1 environment to new host with 5.5. Since that move we have not been able to get the devices to sync and are also seeing higher than normal latency when pinging Self-IP's on the F5's. Both VM's are running 11.6.
Whenever you try to sync the two you always receive " did not receive the last sync successfully". While monitoring /var/log/ltm you can see the peer connection drop then re-establish and also a message constantly coming up with "Bandwidth utilization is 8 Mbps, exceeded 75% of Licensed 8 Mbps".
Another thing that is noticed is with latency while pinging Self-IP's from the F5 and to it. Even when both VE's are on the same host and ping each other's peer IP address we see 1-2ms, if you raise the MTU size up that starts going up. When using a 1500 MTU it goes up to 5-6ms, when using 9000 (9000mtu is enabled) it goes up to 70-80ms.
I have built new VM's from F5 OVA image and re-licensed but the two new ones still see the exact same issue. I built an Ubuntu VM and put it on the same host and peer IP VLAN it has NO problems. If I use the Ubuntu host to ping the peer IP on each F5, all on the same VLAN, I see the latency with the F5.
Any thoughts are suggestions would be much appreciated. Thanks.
UPDATE:
Noticed this from both VM's as well, one is receiving the sync other is sending
