3.3.2 AUTO-NEGOTIATION

Configures the Ethernet interface so that it operates in auto-negotiation mode. Here, the duplex mode is set and the
interface's speed is configured in accordance with the characteristics of the rest of the devices connected to the Eth-
ernet. The device with the worst characteristics limits the rest of devices connected to the Ethernet. If, for example,
several devices can operate at 100 Mbps and one can only operate at 10 Mbps, auto-negotiation configures the in-
terface to 10 Mbps.
Syntax:
ethernetX/X config>auto-negotiation
Example:
ethernet0/0 config>auto-negotiation
ethernet0/0 config>
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.
3.3.2.1 AUTO-NEGOTIATION ADVERTISE
Configures the characteristics advertised in auto-negotiation. To disable the advertising of characteristics, use the
auto-negotiation no advertise option. The following characteristics can be configured:
• flow-control: advertises all flow control options available (symmetric or both symmetric and asymmetric).
• flow-control asymmetric: advertises asymmetric flow control (does not advertise symmetric flow control).
• flow-control symmetric: advertises symmetric flow control (does not advertise asymmetric flow control).
