What is the default vPC peer-keepalive timeout on the Cisco Nexus 7000 Series switch?
A. 5 seconds
B. 256 milliseconds
C. 500 milliseconds
D. 1 second
Correct Answer: D
Explanation/Reference:
Explanation:
If one of the vPC peer devices fails, the vPC peer device on the other side of the vPC peer link senses the failure by not receiving any peer-keepalive messages. The default interval time for the vPC peer-keepalive message is 1 second, and you can configure the interval between 400 milliseconds and 10 seconds.
