Physical links represent the actual physical configuration of network connections between ports. You can view and manage physical links from the equipment window, physical topology map, and the Manage Equipment list form of the NFM-P, on each router using the CLI. Because several key parameters on each end of the physical link depend on each other, configuration errors are possible. An RCA audit can identify configuration errors in physical links. The NFM-P does not provide a solution for configuration problems that the RCA audit identifies for physical links.

By default, the RCA audit detects the following configuration errors in physical links:

• physical port parameters

  • mismatched MTU values

  • mismatched speeds

• Ethernet port parameters

  • Auto-negotiate parameter misconfiguration

  • Duplex parameter misconfiguration

You can configure the RCA audit policy for the physical link to include additional physical link properties in the audit.
