Licensing Requirements and Limitations for Ethernet Interfaces

Licensing Requirements and Limitations for Ethernet Interfaces

Involved Network Element

Other network elements are not required.

Licensing Requirements

Ethernet interface configuration commands are available only after the S1720GW, S1720GWR, and S1720X have the license (WEB management to full management Electronic RTU License) loaded and activated and the switches are restarted. Ethernet interface configuration commands on other models are not under license control.

For details about how to apply for a license, see S Series Switch License Use Guide.

    • Rate: 100 Mbit/s, 1000 Mbit/s, 2500 Mbit/s, 5000 Mbit/s, and 10000 Mbit/s
    • Duplex mode: When the rate is 100 Mbit/s, full-duplex and half-duplex are supported. When the rate is 1000 Mbit/s, 2500 Mbit/s, 5000 Mbit/s, or 10000 Mbit/s, only full-duplex is supported.
    • Auto-negotiation: supported
    • Flow control: supported
    • Flow control auto-negotiation: supported
    • Only the S5720-14X-PWH-SI-AC, S5720-28X-PWH-LI-AC, S6720-32C-SI-AC, S6720-32C-SI-DC, S6720-32C-PWH-SI-AC, S6720-52X-PWH-SI, S6720-56C-PWH-SI-AC, S6720-56C-PWH-SI, and S6720-32C-PWH-SI support MultiGE interfaces.
    • Only the S6720-32C-SI-AC, S6720-32C-SI-DC, S6720-32C-PWH-SI-AC, S6720-52X-PWH-SI, S6720-56C-PWH-SI-AC, S6720-56C-PWH-SI, and S6720-32C-PWH-SI support the rate of 5000 Mbit/s and 10000 Mbit/s.
    • You can set the rate of a MultiGE interface to 100 Mbit/s and duplex mode to half-duplex only when the interface works in auto-negotiation mode on the S5720-14X-PWH-SI-AC. This limitation does not apply to MultiGE interfaces on other switches.
    • After the rate decrease auto-negotiation function is configured on a MultiGE interface of the S5720-28X-PWH-LI-AC and a network cable is removed and reinstalled on the interface in Down state continuously, the interface rate automatically decreases to 1000 Mbit/s. You can remove and reinstall the network cable again after the interface goes Up or run the shutdown and undo shutdown commands on the remote interface to restore the interface rate to 2500 Mbit/s.

    • After running the speed auto-negotiation command to configure rate auto-negotiation on a GE optical interface working in auto-negotiation mode, you cannot configure flow control auto-negotiation on the interface.
    • GE optical interfaces on the S5700S-LI do not support the rate of 100 Mbit/s.
    • GE optical interfaces on the S5700-52X-LI-48CS, S5700-28X-LI-24S, and S5701-28X-LI-24S-AC, the first 24 GE optical interfaces on the S5700-28P-LI-24S-BAT and S5700-28P-LI-24S-4AH support the rate of 100 Mbit/s.

    • The last four GE interfaces (based on the interface number) on the S5720-PC-EI and S5720-P-EI support only GE optical modules and GE copper modules, and the interface rate can only be 1000 Mbit/s.
    • On the S5720S-28P-SI-AC, S5720S-52P-SI-AC, S5720-28P-SI-AC, and S5720-52P-SI-AC, the last four GE interfaces cannot have FE optical modules installed and do not support the rate auto-negotiation configuration.
    • All combo optical interfaces support the rate of 100 Mbit/s.

    • Duplex mode: full-duplex
    • Auto-negotiation: not supported
    • Flow control: supported
    • Flow control auto-negotiation: not supported
    • The XGE interfaces on the ES5D21X02S01 card of the S5720EI and the ES5D21X04S01 card of the S5720HI support XGE optical modules.
    • Only XGE optical interfaces on the S6720LI, S6720S-LI, S6720SI, S6720S-SI, S6720EI and S6720S-EI in V200R009 and later versions can automatically negotiate the rate to 100 Mbit/s after having GE copper modules installed.
    • When used for data transmission between service ports, copper cables can only connect switches of the same subseries, and cannot be used between switches of different subseries or between Huawei and non-Huawei switches.

    40GE optical interfaces

    When the transmission medium is a 40GE optical module:

    • Flow control: supported
    • Flow control auto-negotiation: not supported

    When you run the display interface command on a 40GE optical interface that has a high-speed cable installed, the command output shows that auto-negotiation is enabled. However, you cannot run the negotiation auto command to configure the auto-negotiation mode.

    • All devices providing MultiGE interfaces that comply with the 802.3bz standard
  • On the S5700SI, S5700EI, and S5700HI in V200R003 or V200R005, a GE interface can go Up after it has a GE copper module installed. However, you cannot run corresponding commands to configure the rate, duplex mode, auto-negotiation, MDI, flow control, and virtual cable test on the interface. The 10GE interfaces on the S5700EI do not support GE copper modules.
  • For switches in V200R003C00 and earlier versions, only Layer 2 Ethernet interfaces on the S5700HI, S5710EI, and S5710HI can be configured as Layer 3 interfaces. For switches in V200R005C00 and later versions, only Layer 2 Ethernet interfaces on the S5700HI, S5710EI, S5710HI, S5700EI, S6700EI, S5720EI, S5720HI, S6720EI, and S6720S-EI can be configured as Layer 3 interfaces.
  • Only the S1720GFR and S5700-X-LI support the IFG configuration.

  • Only the XGE optical interfaces that have XGE optical modules installed support unidirectional single-fiber communication without requiring a license. XGE optical interfaces on the S5720-EI, S6720-EI, and S6720S-EI also support unidirectional single-fiber communication after GE optical modules are installed without requiring a license. The S5720HI does not support unidirectional single-fiber communication.

    40GE optical interfaces support unidirectional single-fiber communication only when no optical module is installed or 40GE optical modules are installed.

  • If the license is loaded and activated on the S5720-28P-LI-AC, S5720-28P-PWR-LI-AC, S5720-52P-LI-AC, or S5720-52P-PWR-LI-AC in V200R011C00 and later versions and the switch is restarted, GE optical interfaces upgrade into XGE optical interfaces, which work at a rate of 10 Gbit/s as compared with 1 Gbit/s of GE optical interfaces. If the license becomes invalid or is deactivated, GE optical interfaces on the switch are still displayed as XGE optical interfaces in the command output before the switch is restarted. After the switch is restarted, XGE optical interfaces restore to GE optical interfaces.
  • If the license is loaded and activated on the S5720-28P-LI-AC, S5720-28P-PWR-LI-AC, S5720-52P-LI-AC, and S5720-52P-PWR-LI-AC in V200R011C00 and later versions and the switch is restarted, configuration information will be lost in the following scenarios. Reconfigure the device and run the save command to save the configuration.
    1. In the standalone and stack systems, when the configuration file contains configurations implemented using commands in which GE uplink interfaces are specified and no key word interface is before the specified GE uplink interfaces in views excluding the interface view, such configurations are completely lost if the switch is restarted after the license is loaded.
    2. In the standalone and stack systems, when the configuration file contains configurations implemented using commands in which the key work interface is contained and the specified interfaces are GE uplink interfaces in views excluding the interface view, such configurations and configurations of the GE uplink interfaces are lost if the switch is restarted after the license is loaded.
    3. Assume that a stack system configuration file contains the configuration of a GE uplink port of a member switch. Load the license and restart the stack system. The GE uplink port configuration will be lost if this switch joins the stack system after the stack system is set up.
