What it Means

Check the following output fields and verify that the output shows the intended configuration of IS-IS-enabled interfaces:

• Interface—Interface configured for IS-IS
• State—Internal implementation information
• Circuit id—Circuit identifier
• Circuit type—Configured level of IS-IS:
  • 1—Level 1 only
  • 2—Level 2 only
  • 3—Level 1 and Level 2
• LSP interval—Time between IS-IS information messages
• Sysid—System identifier
• L or Level—Type of adjacency:
  • 1—Level 1 only
  • 2—Level 2 only
  • 3—Level 1 and Level 2
• Adjacencies—Adjacencies established on the interface
• Priority—Priority value established on the interface
• Metric—Metric value for the interface
• Hello(s)—Intervals between hello PDUs
• Hold(s)—Hold time on the interface
