Configuring Ethernet Interfaces; Configuring A Management Ethernet Interface - H3C S7500X Series Interface Configuration Manual

Configuring Ethernet interfaces

The Switch Series supports Ethernet interfaces, management Ethernet interfaces, and Console
interfaces.
Your device supports the following types of Ethernet interfaces:
•
Layer 2 Ethernet interfaces—Physical Ethernet interfaces operating at the data link layer
(Layer 2) to switch packets.
•
Layer 3 Ethernet interfaces—Physical Ethernet interfaces operating at the network layer
(Layer 3) to route packets. You can assign an IP address to a Layer 3 Ethernet interface.
•
Layer-configurable Ethernet interfaces—Physical Ethernet interfaces that can be configured
to operate in bridge mode as Layer 2 Ethernet interfaces or in route mode as Layer 3 Ethernet
interfaces.
•
Layer 3 Ethernet subinterfaces—Logical interfaces operating at the network layer. You can
assign an IP address to a Layer 3 Ethernet subinterface. On a Layer 3 Ethernet interface, you
can create multiple Layer 3 subinterfaces.
This chapter describes how to configure management Ethernet interfaces and Ethernet interfaces.

Configuring a management Ethernet interface

About management Ethernet interface
A management Ethernet interface uses an RJ-45/LC connector. You can connect the interface to a
PC for software loading and system debugging, or connect it to a remote NMS for remote system
management.
Restrictions and guidelines
The management Ethernet interface can be a copper port or fiber port.
•
By default, the duplex mode is auto for a copper port and full for a fiber port. The duplex
command cannot modify the duplex mode to any value other than the default for the copper port
or fiber port.
•
By default, the speed is auto for a copper port and 1000 Mbps for a fiber port. The speed
command cannot modify the speed to any value other than the default for the copper port or
fiber port.
In standalone mode, when the switch has multiple management Ethernet interfaces, only the
management Ethernet interface on the active MPU processes management traffic.
In IRF mode, when an IRF system has multiple management Ethernet interfaces, only the
management Ethernet interface on the global active MPU processes management traffic.
Configuration procedure
