Remarks
By default, the duplex mode is
auto
for
Ethernet interfaces.
For interfaces at two ends of a physical
link to operate correctly, configure the
same duplex mode for them.
Interfaces that operate in 1000 Mbps or a
higher speed do not support the
half
keyword and cannot autonegotiate the
half duplex mode with the peer.
5.
Set the speed for the
Ethernet interface.

By default, an Ethernet interface
autonegotiates the speed with its peer.
Support for the keywords of this command
varies by interface type. For more
information, execute the
speed ?
command in interface view.
For interfaces at two ends of a physical
link to operate correctly, configure the
same speed for them.
The speed of a 10-Gbps or faster fiber
port cannot be configured or
autonegotiated as 100 Mbps or lower.
6.
Set the expected
bandwidth for the
Ethernet interface.
bandwidth
bandwidth-value
By default, the expected bandwidth (in
kbps) is the interface baud rate divided by
1000.
7.
Restore the default
settings for the Ethernet
interface.

8.
Bring up the Ethernet
interface.
undo shutdown
B y default, an Ethernet interface is up.
The
shutdown
,
port
up-mode
, and
loopback
commands are mutually
exclusive.
Configuring an Ethernet subinterface
When you configure an Ethernet subinterface, follow these restrictions and guidelines:
•
To transmit packets between a local Ethernet subinterface and a remote Ethernet subinterface,
configure them with the same subinterface number and VLAN ID.
•
Do not use the VLAN whose ID is an Ethernet subinterface number.
