License classification on S series switch

15

Licenses are classified as follows:
Depending on purpose, licenses are classified into commercial (COMM) licenses and non-commercial (DEMO) licenses.
Commercial license
Generally, these licenses are purchased according to contracts, and are permanently valid.

Non-commercial license
These licenses are used for special purposes such as testing and trial, and are strictly controlled.

Depending on authority, licenses are classified into feature licenses and capacity licenses.
Feature license
License-controlled features cannot be used without a license.
An enhanced feature takes effect only after the value-added feature or another enhanced feature it depends on takes effect. Therefore, both the license for the enhanced function and the license for the dependent function must be installed.

Capacity license
These licenses are used to expand dynamic resources on the product. A capacity license takes effect only after the corresponding feature takes effect. If the feature is a license-controlled one, the license for the feature must be loaded before the capacity license.
Customers can choose not to purchase a capacity license and use the default number of resources supported by the product, or purchase one or more licenses to obtain the total number of resources supported by the purchased licenses.

Firewall license classification
The licenses of firewalls are classified into the following types: -Commercial license It refers to a license purchased with a formal contract. If you need to use functions or features, or extra resources controlled by a license, you need to purchase a license. The commercial licenses are classified into commercial permanent license and commercial temporary license. In principle, license certificates must be issued for commercial permanent licenses (commercial license for short. If otherwise specified, the commercial licenses mentioned in this document refer to commercial permanent license), and license files are issued as e-copies. Generally, commercial temporary licenses are used in the trial or trial before payment scenario. -Non-commercial license It refers to a license used for non-sales purposes such as internal testing, demonstration, or training. No contract is required. The non-commercial license has a certain use period. In principle, the user period of a non-commercial license cannot exceed three months.

Classification of Eth-Trunks on S series switches
Eth-Trunks can work in manual load balancing mode or LACP mode. Eth-Trunk in manual load balancing mode: The manual load balancing mode is a basic link aggregation mode. In this mode, you must manually create an Eth-Trunk, add member interfaces to the Eth-Trunk, and specify active member interfaces. This mode does not involve LACP. All active interfaces forward data and evenly share load. If an active link fails, the remaining active links automatically share the traffic evenly. Eth-Trunk in LACP mode: In LACP mode, you must manually create an Eth-Trunk and add member interfaces to the Eth-Trunk. Different from the Eth-Trunk in manual load balancing mode, active member interfaces in LACP mode are selected using LACP protocol packets. When a group of interfaces are added to an Eth-Trunk, the devices at both ends determine active interfaces and inactive interfaces through the LACP packets. The LACP mode is also called M:N mode. This mode supports both load balancing and redundancy backup functions. In the link aggregation group, M links are active links responsible for data forwarding and load balancing, whereas N links are inactive links working as backup links and do not forward data. If an active link becomes faulty, the system selects the link with the highest priority from the N inactive links to replace the faulty link. The inactive link becomes active and starts to forward data.

License support on S series switch
S series switches support licenses as follows: Among S series fixed switches, only S5720HI switches in V200R006C00 and later versions support license files.(The S5720HI can increase the number of IPv4 FIB entries or connected APs by loading different licenses.) All S series modular switches support license files.

Functions available only after licenses are loaded to S series switch
S series fixed switches: In V200R007 and earlier versions, fixed switches, except S5720HI, do not support license files. All functions are available without the need of license. The S5720HI can increase the number of IPv4 FIB entries or connected APs by loading different licenses. In V200R007, the SVF function is provided by S5720HI after a license is loaded. Other basic functions do not need licenses. S series modular switches: The MPLS, NQA, IPv6, traffic distribution, and SVF features of the S7700&S9700&S12700 are controlled by licenses. Without the corresponding licenses loaded, the commands can be executed, but the functions do not take effect. After the corresponding licenses are loaded, X1E boards can support more FIB entries, PPPoE users, or APs. The MPLS, NQA, IPv6, traffic distribution, and service port cluster features of the S9300 are controlled by licenses. Without the corresponding licenses loaded, the commands can be executed, but the functions do not take effect. In addition, by using different licenses, X1E boards can extend FIB entries. Note: On an S9300, before a service port cluster is established, load licenses to both active/standby chassis.
