- Page 39 Setting up an M-LAG system Multichassis Link Aggregation (M-LAG) virtualizes two physical devices into one system through multichassis link aggregation to provide device-class high availability and load sharing. Compared to IRF, M-LAG offers higher network reliability and shorter service interruption during upgrade.

Connect the grounding cable and power cords for the member "Grounding the switch" and "Connecting the power cord." switches. Power on the switches. Configure the M-LAG system For detailed information about M-LAG, see M-LAG configuration in settings.
- Page 41 As a best practice, establish a dedicated direct link between two M-LAG member devices as a keepalive link. Do not use the keepalive link for any other purposes. Make sure the M-LAG member devices have Layer 2 and Layer 3 connectivity to each other over the keepalive link. You can use management Ethernet interfaces, Layer 3 Ethernet interfaces, Layer 3 aggregate interfaces, or interfaces with a VPN instance bound to set up the keepalive link.
- Page 42 Figure4-4 Top of rack connection scheme Configuring the M-LAG system settings After you install the M-LAG member switches, start and log in to each member switch to configure basic M-LAG system settings, including: • M-LAG system MAC address. • M-LAG system ID. •...
- Page 43 Verifying the configuration To verify the running status of the M-LAG system: Create a Layer 3 interface on a member device, assign it an IP address, and make sure the device and the remote network management station can reach each other. Use Telnet or SNMP to access the device remotely.
- Page 44 Setting up an IRF fabric You can use H3C IRF technology to connect and virtualize switches into a large virtual switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and manageability. A switch can set up an IRF fabric only with switches from the same switch series.

Connect grounding cables and "Grounding the switch" and "Connecting the power cord." power cords Power on the switches Configure basic IRF settings See Virtual Technologies Configuration Guide for the switch series.
- Page 46 You connect the IRF member switches through IRF ports, the logical interfaces for the connections between IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 and IRF-port 2. To use an IRF port, you must bind a minimum of one physical port to it. When connecting two neighboring IRF member switches, you must connect the physical ports of IRF-port 1 on one switch to the physical ports of IRF-port 2 on the other switch.
- Page 47 Figure5-3 IRF fabric in ring topology Identifying physical IRF ports on the member switches Identify the physical IRF ports on the member switches according to your topology and connection scheme. Table5-1 shows the physical ports that can be used for IRF connection and the port use restrictions.
- Page 48 For a long-distance IRF connection, use SFP+/SFP28/QSFP+/QSFP28 transceiver modules and optical fibers. The following subsections describe several H3C recommended IRF connection schemes by using SFP+ cables and SFP+ transceiver modules and fibers. All these schemes use a ring topology. IMPORTANT: In these schemes, all physical IRF ports are located on the same side.
