Metric

Last Updated: 12/12/2016

Metric specifies the interface metric for the IPv4 protocol. When routes are chosen, the overall metric used to determine the preference is the sum of the route metric and the interface metric.

Typically, the interface metric gives preference to a particular interface, assuming two adapters and interfaces are available with connectivity to the same destination. If a preference is not specified, the stack will apply the automatic metric, generated by the stack for each interface.

This scenario will typically apply in a server scenario where the server has multiple Ethernet NICs and will not apply in a client scenario due to the new WCM feature.

If a preference is not specified, the stack will choose an automatic metric, such as automatically preferring wired over wireless.

Values

metric

Specifies the interface metric for the IPv4 protocol. The range is from five (more than 2 gigabytes (GB) per second) to fifty (less than 500 kilobytes (KB) per second).
