Disable a Switch Chip Port

On occasion, you might need to turn off a port. For example, a cable might become damaged and cause symbol errors that affect the switch chip's performance. Use the disableswitchport command to disable a switch chip port and its respective cable connection.

• On the management controller, type.

  FabMan@switch_name->disableswitchport [--reason=reason] Switch port

  where:

  • reason is the reason for disabling the port, Blacklist or Partition.

  • port is the number of the port (1 to 36).

  Alternatively, type.

  FabMan@switch_name->disableswitchport [--reason=reason] connector

  where connector is the number of the QSFP connector (0A to 17B).

  For example:

  FabMan@switch_name->disableswitchport Switch 22
  Disable connector 1A Switch port 22
