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:
