To do... Use the command... Remarks
Set the speed of the
Ethernet port
speed { 10 | 100 | 1000 | auto }
Optional
z By default, the speed of an
Ethernet port is determined
through auto-negotiation (the auto
keyword).
z Use the 1000 keyword for Gigabit
Ethernet ports only.
z The optical interface of an SFP
port does not support the 10 or
100 keyword
Set the medium
dependent interface
(MDI) mode of the
Ethernet port
mdi { across | auto | normal }
Optional
Be default, the MDI mode of an
Ethernet port is auto.
Set the maximum frame
size allowed on the
Ethernet port to 9,216
bytes
jumboframe enable
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
1,536 bytes, use the undo
jumboframe enable command.
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.
z If you expect that 10 Mbps is the only available auto-negotiation speed of the port, you just need to
configure speed auto 10.
z 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.
z 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.
Follow these steps to configure auto-negotiation speeds for a port:

z By default, the port speed is
determined through
auto-negotiation.
z Use the 1000 keyword for Gigabit
Ethernet ports only.
