Table 2-4. Fast Ethernet (10/100) Port Parameters

Parameter

Definition

 

 

Speed Mode

Allows you to select the speed of the port manually

 

(to either 10 or 100 Mbps).

 

Note: If auto-negotiation is enabled, this setting

 

is ignored.

 

 

Duplex Mode

Allows you set the port duplex mode (half- or full-

 

duplex).

 

Note: If auto-negotiation is enabled, this setting

 

is ignored.

 

 

Flow Control

Determines whether flow control is used on this

Mode

port. For half-duplex links, active backpressure

 

jams the sending Ethernet channel until the port’s

 

buffers can receive more packets. This prevents lost

 

or dropped packets.

 

For full-duplex links, IEEE 802.3z pause control

 

allows the port to stop a sending station from

 

sending more packets if the receiving port’s buffers

 

are full.

 

For TX and FX ports, there is an additional option

 

for Enable with Aggressive Backoff. This option

 

limits the size of the bursts.

 

Flow Control is recommended for use primarily on

 

end-station connections. Using flow control on

 

trunk ports can cause unnecessary congestion on

 

the network.

 

 

Auto

Allows you to set the port to auto-negotiate a speed

Negotiation

and duplex mode. Auto-negotiation works best

Mode

when the connection on the other end of the link is

 

set to auto-negotiate as well. If you set a port to

 

auto-negotiate, and the connection is not

 

successful, set the port speed and duplex mode

 

manually.

 

 

Auto

Determines what information the port advertises

Negotiation

when it starts auto-negotiating. In most cases,

Speed/Duplex

10/100 and Half/Full are the best settings, but

Advertisement

there may be cases when you want to auto-

 

negotiate one parameter, while keeping the other

 

fixed.
