5.2.2 Auto-negotiation 
Auto-negotiation is a mechanism that takes control of the cable when a connection is es-
tablished to a network device. Auto-negotiation detects the various modes that exist in the 
network device on the other end of the wire and advertises it own abilities to automatically 
configure the highest performance mode of interoperation. As a standard technology, this 
allows simple, automatic connection of devices that support a variety of modes from a va-
riety of manufacturers. 
To enable/disable the auto-negotiation on an Ethernet port, use the following command. 
Command Mode 
Description 
port nego
 PORTS {on | off} Bridge 
Configures the auto-negotiation of the specified port, 
enter the port number. 
For the hiD 6615 S223/S323, you can configure transmit rate and duplex mode as stan-
dard to configure transmit rate or duplex mode of connected equipment even when auto-
negotiation is enabled. For example, when you configure transmit rate as 10Mbps with 
configured auto-negotiation, a port is worked by the standard 10Mbps/full duplex mode. 
By default, auto-negotiation is activated in 10/100/1000Base-TX port of the hiD 6615 
S223/S323. However you cannot configure auto-nego in fiber port. 
 
The following is an example of deleting auto-negotiate of port 7 and 8, and showing it. 
SWITCH(bridge)# 
SWITCH(bridge)# port nego 7-8 off

5.2.3 Transmit 
Rate 
To set transmit rate of Ethernet port, use the following command. 
Command Mode 
Description 
port speed
 PORTS {10 | 100 | 1000} Bridge 
Sets transmit rate of Ethernet port as 
10/100/1000Mbps, enter the port num-
ber. 
 
When auto-nego is activated, it is impossible to change transmit rate. 
 
The following is an example of configuring transmit rate of port 1 as 10Mbps and showing 
it.
