Configuring An Auto-Negotiation Transmission Rate - HP 4800G Series Configuration Manual

Auto-negotiation mode (auto). Interfaces operating in this mode determine their duplex mode
through auto-negotiation.
Similarly, if you configure the transmission rate for an Ethernet interface by using the speed command
with the auto keyword specified, the transmission rate is determined through auto-negotiation too. For a
Gigabit Ethernet interface, you can specify the transmission rate by its auto-negotiation capacity. For
details, refer to

Configuring an Auto-negotiation Transmission Rate

Follow these steps to configure an Ethernet interface:
To do...
Enter system view
Enter Ethernet
interface view
Set the description
string
Set the duplex mode
Set the transmission
rate
Shut down the
Ethernet interface
10-Gigabit Ethernet ports do not support the duplex command or the speed command.
Configuring an Auto-negotiation Transmission Rate
Usually, the transmission rate on an Ethernet port is determined through negotiation with the peer end,
which can be any rate within the capacity range. With auto-negotiation rate configured, you can enable
the Ethernet port to negotiate only part of the transmission rates within its capacity.
Use the command...
system-view
interface interface-type
interface-number
description text
duplex { auto | full | half }
speed { 10 | 100 | 1000 | auto }
shutdown
1-2
Remarks

—
Optional
By default, the description of an interface
is the interface name followed by the
"interface" string, GigabitEthernet1/0/1
Interface for example.
Optional
auto by default.
The optical interface of an SFP port and
the electrical interface of an Ethernet port
whose port rate is configured as 1000
Mbps do not support the half keyword
Optional
The optical interface of an SFP port does
not support the 10 or 100 keyword.
By default, the port speed is in the
auto-negotiation mode.
Optional
By default, an Ethernet interface is in up
state.
To bring up an Ethernet interface, use the
undo shutdown command.
