(Optional) Creating Bond Ports

You are advised to use the bond port mode for the service network of the HDFS service. bond4 is supported. After being created, this port applies to Global Zone and NameNode Zone. Global Zone and NameNode Zone can use the same bond port, but their IP addresses must be planned separately.

If the bond port mode is not used, skip this step. The following uses eth0 and eth1 of a node as an example to describe how to create bond ports for the HDFS service network.

Prerequisites

The port for which bond ports are created must be a port without configuring an IP address.

Procedure

  1. Log in to the CLI. For details, see Logging In to the CLI.
  2. Run the following command on each node to create a bond port:

    The following uses the 25GE TCP networking as an example to describe how to create bond4 for the eth1 and eth2 ports of a node (management IP address: 192.168.239.56). Table 1 describes more parameters.

    create bond_port general transfer_protocol=TCP bond_name=bond_test1 bond_mode=bond4 port1_name=eth1 port2_name=eth2 node_ip=192.168.239.56

    Table 1 Parameters

    Parameter

    Description

    Value

    transfer_protocol

    Transport protocol
    The value is TCP.
    NOTE:

    The HDFS service network supports only the TCP protocol.

    bond_name

    Bond port name The port name of the HDFS service network can contain only digits, letters, periods (.), hyphens (-), and underscores (_), and must start with a letter and end with a digit or letter. A maximum of 13 characters are allowed.

    hdfs_bond

    bond_mode

    Bond mode
    bond4: mode 4, that is, dynamic link aggregation mode.
    NOTE:

    The HDFS service network supports only the bond4 mode.

    port1_name

    Name of port 1

    eth1

    port2_name

    Name of port 2

    eth2

    node_ip

    Management IP address of a node

    192.168.239.56

    The command output is as follows:

    admin:/>create bond_port general transfer_protocol=TCP bond_name=bond_test1 bond_mode=bond4 port1_name=eth1 port2_name=eth2 node_ip=192.168.239.56
