Type: 100BASE-FX is the technical name of Fast Ethernet over fiber optic cables
Usage:
Fast Iron ICX devices support the following types of SFPs for 100BaseFX:
- Multimode SFP—maximum distance is 2 kilometers
- Long Reach (LR)—maximum distance is 40 kilometers
- Intermediate Reach (IR) —maximum distance is 15 kilometers
Configuration:
After installing a 100Base-FX transceiver, you must use this command to enable 100Base-FX support on the device.
The following example enables support for 100Base-FX on a fiber port.
Device# config t
device(config)# interface ethernet 1/1/6
device(config-if-e1000-1/1/6)# 100-fx
Note:
- The transceiver needs to be installed in the switch for the command to work
Firmware needed to use 100-Fx feature in different models:
The above table gives information on firmware needed on different ICX models for 100-Fx support.

Known Issues:
1) For compatible ICX Switches, it is noticed that configuration 100-fx gets wiped out upon reload.
Details Noticed:
- We notice this issue only when the device is in a stack
- Standalone switch does not have this issue
Workaround:
- Make sure that the member 1 is always active and has higher priority
- Devices needing 100-fx support needs to be part of member 1 only
Note:
- Make sure not to use any other member other than member 1 to be highest priority and active since if any other member is made active other than member 1, 100-fx is noticed to wipe out from active member as well
Fix for this issue: upgrade to 9010f
2) For ICX switches “optical monitor” command cannot be enabled firmware version 9010a to 9010c
