Note
If devices connected with set speeds connect to an Ethernet interface where auto-negotiation is con-
figured, problems may arise.
The auto-negotiation mode with set speeds will be unable to detect the duplex mode of the other end.
Thus, it will configure in half-duplex mode.
Auto-negotiation is mandatory for Gigabit connections. If the speed is set to 1000 Mbps, the device will
internally switch to auto-negotiation mode.
7.6.8.3 autonegotiation advertise
Configures the characteristics advertised in auto-negotiation. To disable advertising for a characteristic, use the
auto-negotiation no advertise option. The following characteristics can be configured:
• Speed 1Gbps, full duplex mode.
• Speed 1 Gbps, half duplex mode.
• Speed 100Mbps, full duplex mode.
• Speed 100Mbps, half duplex mode.
• Speed 10Mbps, full duplex mode.
• Speed 10Mbps, half duplex mode.
• Flow control: advertise all available flow control options (symmetric or both symmetric and asymmetric).
• Flow control asymmetric: advertise asymmetric flow control (do not advertise symmetric flow control).
• Flow control symmetric: advertise symmetric flow control (do not advertise asymmetric flow control).
Example:
Configuring port 1 to negotiate duplex mode (half or full), forcing the speed to 10Mbps.
