Can an S series switches be used without a license

27

Basic functions of S series (except the S1700) and E series switches can be used without a license. Some features cannot be used without a license, such as SVF and traffic distribution. To use these features, apply for licenses for them.

Whether S series switches support NAT
S series switches do not support NAT, but S series modular switches configured with SPUs support NAT. 1. S series fixed switches do not support NAT. 2. S7700 and S9700 series modular switches configured with SPUs support NAT. 3. S9300 series modular switches configured with SPUs support NAT. 4. S12700 series modular switches do not support NAT.

IP address configuration on S series switch
An S series switch, except S1700, supports primary and sub IP addresses on interfaces. Each Layer 3 interface can have multiple IP addresses, including one primary IP addresses and multiple sub IP addresses. (Note: Sub IP addresses become invalid when the primary address is deleted.)Each interface on the modular switch supports 255 sub IP addresses, and each interface on the fixed switch supports 8 sub IP addresses. For example, configure a primary IP address 10.1.0.1 and a sub IP address 10.2.0.1 for VLANIF10, with subnet mask 255.255.255.0. [HUAWEI] interface vlanif 10 [HUAWEI-Vlanif10] ip address 10.1.0.1 255.255.255.0 [HUAWEI-Vlanif10] ip address 10.2.0.1 255.255.255.0 sub (Note: After IP addresses are configured for a VLANIF interface, the clients connected to the switch use one of the IP addresses as gateway address. After sub IP addresses are configured, users can change them as required, but the new IP addresses must be on the same subnet as the primary or one sub IP address; otherwise, the subnets cannot communicate with each other.)For most models in V200R005C00 and later versions, run the undo portswitch command to switch a Layer 2 interface to a Layer 3 interface, and then configure an IP address for the interface. For example, configure a primary IP address 10.1.0.1 and a sub IP address 10.2.0.1 for GE1/0/1, with subnet mask 255.255.255.0. [HUAWEI] interface gigabitethernet 1/0/1 [HUAWEI-GigabitEthernet1/0/1] undo portswitch [HUAWEI-GigabitEthernet1/0/1] ip address 10.1.0.1 255.255.255.0 [HUAWEI-GigabitEthernet1/0/1] ip address 10.2.0.1 255.255.255.0 sub

License classification on S series switch
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.

Does the clock work properly after an S series fixed switch is powered off
If some models and versions of S series fixed switches (except S1700 switches) are powered off, the clock can recover. For some other models and versions, the clock cannot recover. For details, see the following: - For switches running a version earlier than V100R006: The system clock of a switch is implemented by the software. The system saves the system clock if the switch is powered off and restarted manually. If the switch is powered off due to a power failure, the system time is restored to the factory setting. - For switches running V100R006 or V200R001: The system clock of the S3700HI, S5700HI, or S6700 is implemented by the hardware. The system obtains the clock from the hardware if the switch is powered off and restarted manually. System clocks of other models are implemented by the software. The system saves the system clock if a switch is powered off and restarted manually. If the switch is powered off due to a power failure, the system time is restored to the factory setting. - For switches running V200R002 and V200R003: The system clock of the S5700HI or S6700 is implemented by the hardware. The system obtains the clock from the hardware if the switch is powered off and restarted manually. System clocks of other models are implemented by the software. The system saves the system clock if the switch is powered off and restarted manually. If the switch is powered off due to a power failure, the system time is restored to the factory setting. - For switches running V200R005 or a later version: The system clock of the S5700 or S6700 is implemented by the hardware. The system obtains the clock from the hardware if the switch is powered off and restarted manually. System clocks of other models are implemented by the software. The system saves the system clock if a switch is powered off and restarted manually. If the switch is powered off due to a power failure, the system time is restored to the factory setting.
