Enabling and disabling 100BaseFX on Chassis-based and stackable devices

Note: The following procedure applies to Stackable devices and to Chassis-based 100/1000 Fiber interface modules only. The CLI syntax for enabling and disabling 100BaseFX support on these devices differs than on a Compact device. Make sure you refer to the appropriate procedures.
Note: For ICX 8200-24F and ICX 8200-48F devices, 100Base-FX is enabled by default.

FastIron devices support the following types of SFPs for 100BaseFX:

  • Multimode SFP—maximum distance is 2 kilometers
  • Intermediate Reach (IR) —maximum distance is 15 kilometers

For information about supported SFP and SFP+ transceivers on FastIron devices, refer to the RUCKUS Optics Family Datasheet.

Note: Connect the 100BaseFX fiber transceiver after configuring both sides of the link. Otherwise, the link could become unstable, fluctuating between up and down states.

To enable support for 100BaseFX on a fiber port or on a stackable switch, enter commands such as the following. 

device(config)# interface ethernet 1/1/6
device(config-if-1/1/6)# 100-fx

The above commands enable 100BaseFX on port 6 in slot 1.

To disable 100BaseFX support on a fiber port, enter the no form of the command. You must disable 100BaseFX support before inserting a different type of module In the same port. Otherwise, the device will not recognize traffic traversing the port.
