Configuring Port Auto-Negotiation Speed

You can configure an auto-negotiation speed for a port by using the speed auto command.
Take a 10/100/1000 Mbps port as an example.
If you expect that 10 Mbps is the only available auto-negotiation speed of the port, you just need to
configure speed auto 10.
If you expect that 10 Mbps and 100 Mbps are the available auto-negotiation speeds of the port, you
just need to configure speed auto 10 100.
If you expect that 10 Mbps and 1000 Mbps are the available auto-negotiation speeds of the port,
you just need to configure speed auto 10 1000.
Use the command...
system-view
interface interface-type
interface-number
undo shutdown
description text
duplex { auto | full | half }
speed { 10 | 100 | 1000 | auto }
mdi { across | auto | normal }

Optional
By default, the port is enabled.
Use the shutdown command to
disable the port.
Optional
By default, the description string of an
Ethernet port is null.
Optional
By default, the duplex mode of the
port is auto (auto-negotiation).
Optional
By default, the speed of an
Ethernet port is
through auto-negotiation (the auto
keyword).
Use the 1000 keyword for Gigabit
Ethernet ports only.
Optional
Be default, the MDI mode of an
Ethernet port is auto.
Optional
By default, the maximum frame size
allowed on an Ethernet is 9,216
bytes. To set the maximum frame
size allowed on an Ethernet port to
1,522 bytes, use the undo
jumboframe enable command.
