Applies to

  • ONTAP 9
  • Networking

Description

  • A misconfigured netmask value on a LIF will prevent some IP addresses from being reachable.
  • The netmask is used to derive the network number / routing prefix for the interface from the LIF's IP address.
  • If the configured value is incorrect, the wrong network number / prefix will be derived, which will make it impossible for some IP addresses to be reached.
  • It is best to get confirmation from the network team what the correct values are before making a change.
