Configuring An Ethernet Subinterface - H3C S7500X Series Interface Configuration Manual

Step
5. Set the speed for the
Ethernet interface.
6. Set the expected
bandwidth for the
Ethernet interface.
7. Restore the default
settings for the Ethernet
interface.
8. Bring up the Ethernet
interface.

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.
To configure an Ethernet subinterface:
Step
1. Enter system view.
2. Create an Ethernet
subinterface.
3. Set the description for the
Ethernet subinterface.
4. Restore the default settings
for the Ethernet subinterface.
5. Set the expected bandwidth
for the Ethernet subinterface.

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.
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.
By default, the expected bandwidth (in
kbps) is the interface baud rate divided by
1000.

B y default, an Ethernet interface is up.
The shutdown, port up-mode, and
loopback commands are mutually
exclusive.
