Figure 12-10 VAS over 10G Topology: Failover
•
The VAS link does not revert automatically. It will be switched again only if required due to a VAS
server group failure on this link.
• The system always checks only one set of the VAS servers; those on the active VAS link.
Note There is a user-configurable parameter that controls the link-switch rate if there has not been a successful
health check on the current VAS link. The default value of this parameter is less than the failure detection
time. It is recommended to configure a larger value.
Once there is a successful health check on the VAS link, the link switches immediately upon failure (see
How to Configure the Minimum Time between Link Switches, page 12-42).
