ethernet portMode ethernet portMode ✓ 3500 ✓ 9000 9400 ✓ 3900 9300 213 Sets the port speed (10 Mbps or 100 Mbps) and the duplex mode (full-duplex or half-duplex) on individual ports. Valid Minimum Abbreviation e portm Important Considerations ■ You can use this command to configure the same setting on multiple ports simultaneously. When you specify multiple port numbers, the system prompts you to choose the setting and then applies it to all of the ports. ■ The device that is connected to each port must be configured for the same port mode. If the port speeds differ, the link does not come up. If the duplex modes differ, link errors occur. ■ Gigabit Ethernet ports do not support mode options. The value all refers only to ports that support port mode options. ■ If you change to full-duplex mode on the port, a message indicates that collision detection will be disabled unless you configure the connected device to the same duplex mode. ■ Disable autonegotiation on any port on which you are setting a specific port mode. ■ 10/100BASE-TX supports the following modes and speeds: ■ ■ 10 Mbps, full-duplex mode ■ 10 Mbps, half-duplex mode ■ 100 Mbps, full-duplex mode ■ 100 Mbps, half-duplex mode 100BASE-FX supports the following modes and speeds: ■ 100 Mbps, full-duplex mode ■ 100 Mbps, half-duplex mode
