Command History
Version Description
9.7(0.0) Introduced on the M I/O Aggregator.
Usage Information
Use this command to congure the protocol-specic resolution value that converts the actual metric of an IPv4
route in the routing table to a scaled metric in the range 0 to 255.
The UP/DOWN state of a tracked IPv4 route is determined by a user-congurable threshold (the threshold
metric command) for the route’s metric in the routing table. To provide a common tracking interface for dierent
clients, route metrics are scaled in the range 0 to 255, where 0 is connected and 255 is inaccessible.
The protocol-specic resolution value calculates the scaled metric by dividing a route's cost by the resolution value
set for the route protocol:
• For ISIS, you can set the resolution in the range 1 to 1000, where the default is 10.
• For OSPF, you can set the resolution in the range 1 to 1592, where the default is 1.
• The resolution value used to map static routes is not congurable. By default, Dell Networking OS assigns a
metric of 0 to static routes.
• The resolution value used to map RIP routes is not congurable. The RIP hop-count is automatically multiplied
by 16 to scale it. For example, a RIP metric of 16 (unreachable) scales to 256, which considers the route to be
DOWN.
