Usage Guidelines

You can run the display isis cost interface command to check costs of an IS-IS interface, including the link cost and route prefix cost that the interface uses in each topology, and how the costs are generated.

Example

# Display costs of VLANIF 100 and how they are generated.

<HUAWEI> display isis cost interface vlanif 100

Interface: Vlanif 100
                             Level-2 interface cost
 Topology base(0):
  Link effective cost: 10(A)                           enabled by circuit cost
  IP prefix effective cost:
   10.10.7.0/24                    cost: 10            enabled by circuit cost
   10.10.8.0/24                    cost: 10            enabled by circuit cost
   10.10.9.0/24                    cost: 10            enabled by circuit cost
 Topology red(7):
  Link effective cost: 87(A)                           enabled by circuit cost
  IP prefix effective cost:
   10.10.7.0/24                    cost: 87            enabled by circuit cost
   10.10.8.0/24                    cost: 87            enabled by circuit cost
   10.10.9.0/24                    cost: 87            enabled by circuit cost

                    Flags: R-Relative cost  A-Absolute cost
