CX910 Switch Module V100R001C00 User Guide 22

This document describes the CX910 10GE switch module (CX910 for short) of the Tecal E9000 server in terms of its features, installation, removal, and configuration. This document applies to the CX910 whose GE/10GE switching planes use the software versions of 1.1.x.x.x, and 1.23-1.99.

Logging In to the CLI of Each Switching Plane

Logging In to the CLI of Each Switching Plane

Scenarios

You can log in to the CLI of each switching plane for the CX910 by using one of the following methods:

  • Over SSH: Remotely log in to the CLI of each switching plane for the CX910 over an Ethernet. You do not need to reconnect the network cable when switching between the CLIs of different switching planes for the CX910.
  • Over SOL: Select a serial port for logging in to a switching plane of the CX910 by using the MM910 SOL user interface (UI) to log in to the CLI.
  • Over a serial port: Directly connect to the SYS serial port of the CX910 by using a serial cable to log in to the CLI, without using an IP address.

Prerequisites

Data

Table 4-7 lists the default data to be prepared.

Login Method

10GE switching plane

  • User name: root
  • Password: Huawei12#$
  • Serial port
  • SSH
  • SOL

Tools

If you want to log in to a server CLI over a serial port, prepare the following hardware:

  • PC with an RS232 serial port
  • DB9-RJ45 cable

Procedure

  • Log in to the CLI of a switching plane over SSH.
  1. Connect the Ethernet port on a PC to the MGMT network ports on the panels of the active and standby MM910s over a local area network (LAN).
  2. Use an SSH connection tool to connect to the IP address of a switching plane to log in to the CLI of the switching plane.

    This document describes how to use PuTTY to log in over SSH. For details, see Logging In to a Server Over a Network Port by Using PuTTY.

Log in to the CLI of a switching plane over SOL.

  1. Connect the Ethernet port on the PC to the MGMT port on the active or standby MM910.

    Figure 4-3 shows the network connections.

    Figure 4-3 Network connections
    NOTE:
    • For MM910 (U54) 2.25 or earlier, the MM910s communicate with external network devices through the ports on switch modules in slots 2X and 3X by default. For MM910 later than (U54) 2.25, the MM910s communicate with external network devices through their MGMT ports by default. To query the MM910 version, see MM910 Management Module V100R001 User Guide.
    • You can run the outportmode command to change the MM910 management network port connection mode. If the MM910s communicate with external network devices through the switch module ports, do not connect the MM910 MGMT ports and the switch module ports to the same network. Otherwise, a network storm will occur and the network will be interrupted. For details, see MM910 Management Module V100R001 Command Reference.

  2. Open an SSH connection tool and enter the floating IP address of the MM910 to visit the MM910 CLI.

    In this document, PuTTY is used as an example during login over SSH. For details, see Logging In to a Server Over a Network Port by Using PuTTY.

  3. Log in to the CLI of a switching plane over MM910 SOL.

    For details, see Logging In to a Compute Node or a Switch Module over SOL.

  • Log in to the CLI of a switching plane over a serial port.
  1. Connect the PC RS232 serial port to the BMC serial port on the CX910 panel by using a DB9-RJ45 cable.
  2. Use a serial port communication tool to log in to the BMC CLI.

    The key communication parameters are as follows:

    • Serial Line to connect to: COMn
    • Speed (baud): 115200
    • Data bits: 8
    • Stop bits: 1
    • Parity: None
    • Flow control: None
    NOTE:

    n indicates the serial port number, and the value is an integer.

    This document describes how to use PuTTY to log in over a serial port. For details, see Logging In to a Server Over a Serial Port by Using PuTTY.

  3. Run the following command on the BMC CLI to switch the SYS serial port to the switching plane to which you want to log in:

    ipmcset -d systemcom -v <option>

    In the command, option indicates the ID for a switching plane. The value ranges from 0 to 2.

    • 1: Fabric Com, which corresponds to the 10GE switching plane of the CX910.
    • 2: Thirty Com. This value is meaningless.

      For example, if you want to switch the SYS serial port to the 10GE switching plane, run the following command:

      root@BMC:/#ipmcset -d systemcom -v 1

      If the switching is successful, the following information is displayed:

      Set systemcom successfully! 
      Serial port direction is:Fabric Com     

  4. Use a DB9-RJ45 cable to connect the RS232 serial port of the PC to the SYS serial port on the CX910 panel.
  5. Use a serial port communication tool to log in to the CLI of a switching plane.

    The key communication parameters are as follows:

    • Serial Line to connect to: COMn
    • Speed (baud): 115200 bit/s
    • Data bits: 8
    • Stop bits: 1
    • Parity: None
    • Flow control: None
    NOTE:

    n indicates the serial port number, and the value is an integer.
