Configuring Auto Negotiation And Crossover Settings; Enabling And Disabling Auto Negotiation - Alcatel OmniSwitch 6800 Series Network Configuration Manual

Configuring Ethernet Ports
To configure the inter-frame gap on a range of ports enter interfaces, followed by the slot number, a slash
(/), the first port number, a hyphen (-), the last port number, ifg, and the desired inter-frame gap value. For
example, to set the inter-frame gap value on ports 20 through 22 on slot 2 to 10 bytes enter:
-> interfaces 2/20-22 ifg 10
As an option, you can document the interface type by entering ethernet, fastethernet, or gigaethernet
before the slot number. For example, to set the inter-frame gap value on port 20 on slot 2 to 10 bytes and
document the port as Gigabit Ethernet enter:
-> interfaces gigaethernet 2/20 ifg 10
Note. Since the interfaces ifg command is only supported on Gigabit interfaces only the gigaethernet
keyword should be used.

Configuring Auto Negotiation and Crossover Settings

The following subsections describe how to enable and disable auto negotiation (see
Disabling Auto Negotiation" on page
over Settings" on page

Enabling and Disabling Auto Negotiation

By default, auto negotiation is enabled. To enable or disable auto negotiation on a single port, a range of
ports, or an entire slot use the
page 1-16 and "Setting Combo Ethernet Port Parameters" on page 1-17
To enable or disable auto negotiation on an entire switch enter interfaces followed by the slot number,
autoneg, and either enable or disable. For example, to enable auto negotiation on slot 2 enter:
-> interfaces 2 autoneg enable
To enable or disable auto negotiation on a single port enter interfaces followed by the slot number, a slash
(/), the port number, autoneg, and either enable or disable. For example, to enable auto negotiation on
port 3 on slot 2 enter:
-> interfaces 2/3 autoneg enable
To enable or disable auto negotiation on a range of ports enter interfaces followed by the slot number, a
slash (/), the first port number, a hyphen (-), the last port number, autoneg, and either enable or disable.
For example, to enable auto negotiation on ports 1 through 3 on slot 2 enter:
-> interfaces 2/1-3 autoneg enable
As an option, you can document the interface type by entering ethernet, fastethernet, or gigaethernet
before the slot number. For example, to enable auto negotiation on port 3 on slot 2 and document the port
as Ethernet enter:
-> interfaces ethernet 2/3 autoneg enable
