Bug Id: | CSCuq29087 | Title: | Periodic BFD Session Flaps on CSR1000v running 3.13.0 |
|
Status: | Fixed |
|
Severity: | 2 Severe |
Description: | Symptom:
The primary symptom in this case is intermittent BFD session flaps on the CSR. The session flaps occur when the CSR does not send necessary BFD control packets within the appropriate time interval. Those packets are late because the associated timer events are lost. Bad host BIOS settings that increase the time it takes the VM to resume running on a physical processor can aggravate this issue.
Conditions:
CSR VM running on vSphere 5.5 (should only affect VMs > 2 vCPUs)
More likely to occur on host with less than optimal BIOS settings related to power management
Workaround:
This issue is resolved in later CSR releases: 3.13.4, 3.14.3, 3.15.2, and 3.16. An upgrade to one of these releases is the best solution.
You can also try to modify the host BIOS settings, exact settings vary depending on type of host.
Generally, you want to do the following things:
1. Disable C-states
2. Disable Package C-states
3. Set any power-saving related option to maximum performance setting
VMware documentation and server documentation will generally provide guidance on low-latency BIOS settings that are generally best for hosts with CSR VMs.
Further Problem Description:
CSR1000v sensitivity to environmental time loss.
