Support for the DHCP snooping location transition function on S series switch
S series switches (except S1700 switches) in V100R003 and later versions support the DHCP snooping location transition function, which is enabled by default.

What is the support of DHCP on an AR
The support for DHCP functions on the AR is as follows: - DHCP server: All AR models of all versions support the DHCP server. - DHCP relay: All AR models of all versions support the DHCP relay agent. - DHCP snooping: Starting from V200R003C00, all AR models support DHCP snooping. - DHCP client: All AR models of all versions support the DHCP client.

Which versions do not support user level change
Run the super password command to set the password used to change a user from a lower level to a higher level. By default, the system does not set the password used to change a user from a lower level to a higher level. Set this password to ensure successful user level changes. Only V100R006C03, V100R006C05, V200R003 and V200R005 do not support the super password command for setting the password used to change a user from a lower level to a higher level. NOTICE: Huawei switches use the combination of user name, password, and level to control users' operation rights. If you use the super command to switch user levels, this right control method will become invalid. Moreover, any user can use the super password of a higher level to obtain high-level operation rights. Therefore, you are not advised to use the super command to switch user levels.

In which situation is a DHCP snooping binding entry generated
Information about generating DHCP snooping binding entries is as follows: 1. When the dhcp snooping enable command is not run on the user-side interface and the network-side interface is not configured as a trust interface, users can go online, but no DHCP snooping binding entry is generated. 2. When the dhcp snooping enable command is not run on the user-side interface and the network-side interface is configured as a trust interface, users can go online, but no DHCP snooping binding entry is generated. 3. When the dhcp snooping enable command is run on the user-side interface and the network-side interface is not configured as a trust interface, users cannot go online, but no DHCP snooping binding entry is generated. 4. When the dhcp snooping disable command is run on the user-side interface, users can go online, but no DHCP snooping binding entry is generated no matter whether the network-side interface is configured as a trust interface. 5. When the dhcp snooping enable command is run on the user-side interface and both user-side and network-side interfaces are configured as trust interfaces, users can go online, but no DHCP snooping binding entry is generated. If the DHCP snooping function has been enabled but no DHCP snooping entry is generated, you can check device configuration in the preceding aspects.
