Basic port parameter configuration
Enabling and disabling support for 100BaseTX
For FastIron X Series devices, you can configure a 1000Base-TX SFP (part number E1MG-TX) to
operate at a speed of 100 Mbps. To do so, enter the 100-tx command at the Interface level of the
CLI.
Brocade(config-if-e1000-11)# 100-tx
After the link is up, it will be in 100M/full-duplex mode, as shown in the following example.
The show media command will display the SFP transceiver as 1G M-TX.
Syntax: [no] 100-tx
To disable support, enter the no form of the command.
100BaseTX configuration notes
• This feature requires that autonegotiation be enabled on the other end of the link.
• Although combo ports (ports 1 – 4) on Hybrid Fiber (HF) models support the 1000Base-TX SFP,
they cannot be configured to operate at 100 Mbps. The 100 Mbps operating speed is
supported only with non-combo ports (ports 5-24).
• The FCX624S-F is the only FCX model that supports the 1000Base-TX SFP module, and only on
the non-combo ports (ports 5-24). The FCX624S-F does not have a specific command to
enable the 1000Base-TX SFP optic at 100 Mbps. You must manually configure it with the
speed-duplex 100-full command. Refer to “Port speed and duplex mode configuration syntax”
on page 41.
• 1000Base-TX modules must be configured individually, one interface at a time.
• 1000Base-TX modules do not support Digital Optical Monitoring.
• This module requires a Cat5 cable and uses an RJ45 connector.
• Hotswap is supported for this module when it is configured in 100M mode.
Enabling and disabling support for 100BaseFX
Some Brocade devices support 100BaseFX fiber transceivers. After you physically install a
100BaseFX transceiver, you must enter a CLI command to enable it.
NOTE
The CLI syntax for enabling and disabling 100BaseFX support on a FESX Compact device differs
from the syntax for Chassis-based and Stackable devices. Follow the appropriate instructions below.
Enabling and disabling support for 100BaseFX is not supported on ICX devices. For information
about supported SFP and SFP+ transceivers on ICX devices, refer to the following Brocade website:
