What Is an RTU License?

Right to Use (RTU) is an authorization mode for selling hardware capabilities, such as the number of flows, capacity, and ports. An RTU license cannot be migrated after being bound to a device. RTU is a part of hardware value, and its life cycle is the same as that of the corresponding hardware.

Table 1-1 lists the licenses supported by S series switches. An RTU license is a type of resource license.

Table 1-1 License classification

License Type

Description

Functional license

A functional license controls  the use of a specific function on a device. If a user wants to use a  restricted function, the user must be authorized to use the function.

For example, if you want to  use the distributed Virtual Extensible LAN (VXLAN) gateway and BGP Ethernet  VPN (EVPN) functions, you need to purchase the VXLAN enhanced function  authorization license.

Resource license

Resource licenses control the  number of resource items available to users. If a user wants to use a  resource item, the user must be authorized to use the resource item.

Based on actual service  requirements, you can use default resources supported by the product without  purchasing resource licenses, or purchase one or more resource licenses. The  resource quantity is the sum of all resources in all selected resource  licenses.

Based on the resource type,  resource licenses are classified into software and hardware resource  licenses.

·          Software resource license: For example, the S5700 supports a maximum  of 16 APs by default. To increase the number of APs that can be connected to  the S5700, purchase the WLAN access controller AP resource license. This  license is a software resource license.

·          Hardware resource license: RTU  license For example, the default interface rate of the  S5732-H24UM2CC is 2.5 Gbit/s. To increase the interface rate to 10 Gbit/s,  purchase the RTU license for upgrading a 2.5GE interface to a 10GE interface.

RTU Licenses Supported by S5700 Switches

The RTU licenses supported by the S5700 series switches are used to increase the interface rate of the switches. The following table lists the license control items. Different models of S5700 series switches support different RTU licenses. For details, see "License Control Items" in the S5700 Series Switches License Usage Guide.

How to Use RTU Licenses of S5700 Switches

How to Use the RTU License for Increasing the Rate of 40GE Uplink Interfaces

·         The rate of six fixed uplink interfaces must be increased at a time.

·         After the license is loaded, run the assign port-type 100GE [ slot slotid | all ] command and restart the device to increase the interface rate to 100 Gbit/s.

How to Use the RTU License for Increasing the Rate of a Group of Interfaces Fixed Mappings Between Groups and Interfaces

Mappings between groups and interfaces are fixed and cannot be modified. To check the mappings, run the display device group-speed configuration command.

<HUAWEI> display device group-speed configuration

How to Make the Increased Interface Rate Take Effect

After the license is loaded, run the assign group-speed [ slot slotnumber ] group group-number speed command and restart the device. For example, to increase the rate of 12 interfaces in group 1 to 5 Gbit/s, run the following commands:

<HUAWEI> system-view

[HUAWEI] assign group-speed group 1 5000  //After this command is run, restart the device to make the increased interface rate take effect.

Guidelines to Follow When the Command Configuration Is Inconsistent with the License Control Item

Table 1-3 Guidelines to follow when the command configuration is inconsistent with the license control item

Guidelines

Example

If the interface rate  configured in the command is less than that supported by a license control  item, the interface rate configured in the command takes effect.

For example:

The assign group-speed group 1 5000 command  increases the rate of 12 interfaces in group 1 from 2.5 Gbit/s to 5 Gbit/s.  The control item in the license file is to increase the rate of 2.5GE  interfaces to 10 Gbit/s.

After the license is activated  and the device is restarted, the rate of 12 interfaces in group 1 is  increased from 2.5 Gbit/s to 5 Gbit/s.

If the interface rate  configured in the command is greater than that supported by a license control  item, the interface rate supported by the license control item takes effect.

For example:

The assign group-speed group 1 10000 command  increases the rate of 12 interfaces in group 1 from 2.5 Gbit/s to 10 Gbit/s.  The control item in the license file is to increase the rate of 2.5GE  interfaces to 5 Gbit/s.

After the license is activated  and the device is restarted, the rate of 12 interfaces in group 1 is  increased from 2.5 Gbit/s to 5 Gbit/s.

If license control items are  insufficient, the rate of interfaces in groups with smaller group IDs is  increased.

For example:

The assign group-speed group 0 10000 and assign group-speed group 1  10000 commands increase the rate of 12 interfaces in  groups 1 and 2 from 2.5 Gbit/s to 10 Gbit/s, and there is only license  control item for increasing the rate of 2.5GE interfaces to 10 Gbit/s.

After the license is activated  and the device is restarted, only the rate of 12 interfaces in group 1 can be  increased from 2.5 Gbit/s to 10 Gbit/s.

  Increasing the Interface Rate Using Multiple Licenses

The rate of a group of interfaces can be increased using multiple licenses.

For example, you have purchased a license for increasing the rate of 2.5GE interfaces to 5 Gbit/s and have increased the interface rate to 5 Gbit/s. Due to service expansion, the interface rate needs to be increased to 10 Gbit/s. In this case, purchase a license for increasing the rate of 5GE interfaces to 10 Gbit/s.

For another example, you have purchased a license for increasing the rate of 2.5GE interfaces to 5 Gbit/s and a license for increasing the rate of 5GE interfaces to 10 Gbit/s. Due to service development, the rate of 2.5GE interfaces needs to be increased to 10 Gbit/s. In this case, you can use the two purchased licenses to increase the interface rate to 10 Gbit/s, removing the need to purchase the license for increasing the rate of 2.5GE interfaces to 10 Gbit/s.

Multiple Interfaces Sharing the Same License

A license can be used by multiple interfaces.

For example, you have purchased a license for increasing the rate of 2.5GE interfaces to 10 Gbit/s. Due to service development, the rate of 12 interfaces in one group needs to be increased from 2.5 Gbit/s to 5 Gbit/s and the rate of 12 interfaces in the other group needs to be increased from 5 Gbit/s to 10 Gbit/s without changing the networking. In this case, you can use the purchased license without having to purchase another two licenses.

Processing RTU Licenses in a Stack

Similar to other licenses, the licenses of a stack are determined by the licenses of the stack master switch. For details, see "How Do I Install a License for a Stack of S Series Switches?"

Method to Use RTU Licenses to Increase the Interface Rate

Introduction to Huawei Fixed Switches

Introduction to Huawei Fixed Switches

Huawei Campus Switch includes S1700, S2300, S2700, S3300, S3700, S5300, S5700, S600-E, S6300, S6700, S7700, S7900, S9300, S9300X, S9700, S12700 Series. In this article, HongTelecom will introduce the Huawei Fixed Switches .

Distinguish Switch Models Based on Layer 3 Features

Huawei fixed switches consist of the S1700, S2700, S3700, S5700 and S6700 series.

What Constraints on USB-based deployment of Huawei S5700 Series Switch

The file system format of the USB flash drive must be FAT32, and standard for the USB interface is USB2.0 (USB1.1 interface on the S5700LI). To ensure compatibility between USB flash drives and devices, use Huawei-certified USB flash drives to configure the Huawei devices. Table 2 lists the USB flash drives applicable to a switch.

Only one USB flash drive can be connected to a device.

In V200R005C00 and later versions, USB-based deployment using a smart_config.ini index file is supported, and this deployment mode is supported in a stack. The USB flash drive must be connected to the master switch of the stack. If it is connected to the standby switch or a slave switch, the USB-based deployment process will not start.

USB-based deployment using the usbload_config.txt index file can only be performed in a single switch, not a stack of multiple switches. In a stack of multiple switches, if the USB flash drive is connected to the standby switch or a slave switch, the USB-based deployment process will not start. If the USB flash drive is connected to the master switch, the USB indicator blinks red fast, indicating that the USB-based deployment fails. In this case, the switch records an error report including the following information: The usbload_config.txt index file cannot be used for USB deployment of a multi-member stack.

The S5710-X-LI, S5720SI, S5720S-SI, S6720EI, S6720S-EI, S5720EI and S5720HI series switches support only the smart_config.ini format.

The S5700S-28X-LI-AC, S5700S-52X-LI-AC, and S5700S-28P-PWR-LI-AC in the S5700S-LI series support only the smart_config.ini format.

Fields in an index file are restricted by the current system version. For example, if some fields in the index file are not supported by the current system version, these fields are invalid for an upgrade to a later version.

USB-based deployment is mutually exclusive with the SVF, web initial login mode and EasyDeploy functions.

How configure IP Multicast of Huawei Switch

Involved Network Elements

An IPv6 multicast network consists of the following network elements:

Multicast source: sends multicast data to receiver hosts. For example, a video server is a multicast source.

Device running IPv6 Protocol Independent Multicast (PIM): uses the PIM (IPv6) protocol to generate and maintain multicast routing entries and forwards multicast data based on multicast routing entries. On an IPv6 multicast network, all Layer 3 devices must run PIM (IPv6); otherwise, multicast forwarding paths cannot be established.

MLD querier: exchanges MLD messages with receiver hosts to create and maintain group memberships. On a multicast network, Layer 3 devices connected to network segments of receivers must run the MLD protocol or be configured with static MLD groups. Otherwise, upstream PIM devices cannot know the multicast groups that users want to join, and therefore cannot establish multicast forwarding paths.

Device running MLD snooping: listens on MLD messages exchanged between upstream Layer 3 multicast devices and receiver hosts to create and maintain Layer 2 multicast forwarding entries, which are used for accurate multicast data forwarding on a Layer 2 network. To prevent broadcasting of multicast packets on a Layer 2 network and conserve network bandwidth, it is recommended that you configure MLD snooping on Layer 2 devices.

Receiver: multicast user that receives multicast data. A receiver can be a PC, a set top box, or any device with multicast client installed.

The "MLD Configuration" chapter mainly describes how to configure a Layer 3 device as an MLD querier.

What’s the Feature Dependencies and Limitations When Link Aggregation of Huawei Switch (2)

Configuration Notes After an Eth-Trunk Is Configured

An Ethernet interface can be added to only one Eth-Trunk. To add an Ethernet interface to another Eth-Trunk, delete it from the original one first.

After an interface is added to an Eth-Trunk, only the Eth-Trunk learns MAC address entries or ARP entries, but the member interface does not.

Before deleting an Eth-Trunk, delete member interfaces from the Eth-Trunk.

Specifications

Link aggregation mode:

Manual

LACP

Link aggregation modes supported by the device

Intra-device: Member interfaces of an Eth-Trunk are located on the same device.

Inter-stack-device: Member interfaces of an Eth-Trunk are located on member devices of a stack. For details, see Link Aggregation in Stack Scenarios.
