Configuring Ethernet interfaces by using the command line

You can configure the Ethernet interfaces by using the command interface.

About this task

To configure an Ethernet interface from the command line, you enter Ethernet configuration mode, specifying the interface to configure, and enter the required Ethernet commands.

Note: There are restrictions on changing the IP addresses of the Ethernet ports used by high availability and disaster recovery configurations. See Changing IP addresses in high availability configurations and Changing IP addresses in disaster recovery configurations.

Procedure

  1. Connect to the IBM® MQ Appliance as described in Command line access. Log in as an administrative user.
  2. Type config to enter global configuration mode.
  3. Type the following command to configure an Ethernet interface: 
    ethernet name
    Where name identifies the interface that you want to configure and has one of the following values:
    • eth10
    • eth11
    • eth12
    • eth13
    • eth14
    • eth15
    • eth16
    • eth17
    • eth20
    • eth21
    • eth22
    • eth23
    • eth30
    • eth31
    • eth32
    • eth33
    • eth40
    • eth41
    • mgt0
    • mgt1
  4. Use the following Ethernet interface commands to configure the interface:
    Command Description
    admin-state Sets the administrative state for the configuration.
    flow-control Sets the flow control mode of the Ethernet interface.
    ip-address Assigns the primary network address for the Ethernet interface.
    ip-config-mode Identifies the configuration mode for the Ethernet interface.
    ip-route Manages static routes in the routing table for the Ethernet interface.
    ip-secondary-address Manages secondary network addresses for the Ethernet interface.
    ipv4-default-gateway Designates the default IPv4 gateway for the Ethernet interface.
    ipv6-dadtransmits Sets the number of IPv6 duplication address detection attempts for the Ethernet interface.
    ipv6-default-gateway Designates the default IPv6 gateway for the Ethernet interface.
    ipv6-nd-retransmit-timer Sets the interval between IPv6 neighbor discovery attempts for the Ethernet interface.
    link-aggegation-model Indicates whether the Ethernet interface is part of an aggregate interface.
    mac-address Changes the MAC address for the Ethernet interface.
    mode Sets the interface speed and direction.
    mtu Sets the maximum transmission unit of the Ethernet interface.
  5. Use the following commands to control the interface, if required:
    Command Description
    disable-ethernet-hardware-offload Manages the temporary disabling of hardware offload.
    packet-capture Manages a packet-capture for the Ethernet interface session.
  6. After you configure the Ethernet interface, enter exit to save the configuration and exit, or type cancel to exit without saving.

Example

The following commands configure interface eth10 to use DHCP: 
mqa# config
Global configuration mode
mqa(config)# ethernet eth10
Modify Ethernet Interface configuration

mqa(config ethernet eth10)# ip-config-mode dhcp
mqa(config ethernet eth10)# exit
mqa(config)# write memory
Overwrite previously saved configuration? Yes/No [y/n]: y
Configuration saved successfully.
