ICX Switch Model 100Base-FX SFP optic support, configuration, firmware and known issues

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:

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
