Management Interfaces and Management IP Addresses of S Series Switches

Console Port

You can log in to a switch through the console port of the switch when you log in to the switch for the first time or cannot remotely log in to the switch, or the switch cannot start. To log in to a switch through the console port of the switch, connect the serial port of your PC to the console port of the switch using a dedicated console cable. Then you can perform related configurations to manage the switch locally. For details, see First Login Through the Console Port. As the basic login mode, login through the console port is out-of-band management mode and is the basis for other login modes such as Telnet login and STelnet login. Figure 1-1 shows the connection between a PC and a switch through the console port.

Mini USB Port

If no console port is available on a switch, use a mini USB cable to connect the USB port of a PC to the mini USB port of the switch for the first login to the switch and then configure and manage the switch. For details, see First Login Through the Mini USB Port. Communication parameters and login configurations are the same between login through the mini USB port and login through the console port, and the only difference is the connection mode. Management through mini USB port or a console port is out-of-band management. When both the mini USB port and console port have a cable connected, only the mini USB port works. Figure 1-2 shows the connection between a PC and a switch through the mini USB port.

Ethernet Management Port

An Ethernet management port is a special Ethernet interface that can be assigned an IP address but does not transmit services. Management through an Ethernet management port is out-of-band management. The Ethernet management port of a fixed switch refers to the MEth interface, and that of a modular switch refers to the ETH interface. Figure 1-3 shows the connection between a PC and a switch through the Ethernet management port.

Service Interface

A service interface is an Ethernet interface that transmits services. When you configure and manage a switch through its service interface, the management data and service data on the network are transmitted over the same link, that is, in-band management is used. Figure 1-4 shows the connection between a PC and a switch through a service interface.

Configuring a Management IP Address on an Ethernet Management Port

• For fixed switches:
  1. Run the interface MEth 0/0/1 command to enter the MEth interface view.

     <HUAWEI> system-view 
     [HUAWEI] interface MEth 0/0/1

  2. Run the ip address ip-address { mask | mask-length } command to configure an IP address for the MEth interface. The following assumes that the IP address of the Ethernet management port is 10.1.1.1/24.

     [HUAWEI-MEth0/0/1] ip address 10.1.1.1 24

• For modular switches:
  1. Run the interface Ethernet 0/0/0 command to enter the ETH interface view.

     <HUAWEI> system-view 
     [HUAWEI] interface Ethernet 0/0/0

  2. Run the ip address ip-address { mask | mask-length } command to configure an IP address for the ETH interface. The following assumes that the IP address of the Ethernet management port is 10.1.1.2/24.

     [HUAWEI-Ethernet0/0/0] ip address 10.1.1.2 24

Configuring a Management IP Address on a Service Interface

• Configure a management IP address on a service interface after the interface is changed to Layer 3 mode.
  1. Run the interface interface-type interface-number command to enter the Ethernet interface view. The following assumes that the interface connecting the switch to the PC is GigabitEthernet0/0/1.

     <HUAWEI> system-view 
     [HUAWEI] interface GigabitEthernet 0/0/1

  2. Run the undo portswitch command to change the working mode of the interface to Layer 3. By default, an Ethernet interface works in Layer 2 mode.

     [HUAWEI-GigabitEthernet0/0/1] undo portswitch

  3. Run the ip address ip-address { mask | mask-length } command to configure an IP address for the interface. The following assumes that the IP address of the Layer 3 interface is 10.1.1.3/24.

     [HUAWEI-GigabitEthernet0/0/1] ip address 10.1.1.3 24

• Configure a management IP address on a VLANIF interface of the VLAN to which a service interface is added.
  1. Run the interface interface-type interface-number command to enter the Ethernet interface view. The following assumes that the interface connecting the switch to the PC is GigabitEthernet0/0/1.

     <HUAWEI> system-view 
     [HUAWEI] interface GigabitEthernet 0/0/1

  2. Run the port link-type access command to set the link type to access.

     [HUAWEI-GigabitEthernet0/0/1] port link-type access

  3. Run the port default vlan vlan-id command to configure the default VLAN for the interface and add the interface to the VLAN.

     [HUAWEI-GigabitEthernet0/0/1] port default vlan 4094
     [HUAWEI-GigabitEthernet0/0/1] quit

  4. Run the interface Vlanif vlan-id command to create a VLANIF interface for the specified and enter the VLANIF interface view.

     [HUAWEI] interface Vlanif 4094

  5. Run the ip address ip-address { mask | mask-length } command to configure an IP address for the VLANIF interface. The following assumes that the IP address of the VLANIF interface is 10.1.1.4/24.

     [HUAWEI-Vlanif4094] ip address 10.1.1.4 24
