Can a switch's IP address and a user's IP and MAC addresses be carried when a Portal authentication page is pushed on an S series switch

No, this function is not supported.

Types of packets checked by S series switches with IPSG enabled
For S series switches (except S1700 switches), IPSG takes effect only for IP packets (except DHCP packets) but not for packets of other types such as ARP or PPPoE. With IPSG enabled, an S series switch checks only IPv4 packets in versions earlier than V200R001 and checks all IPv4 and IPv6 packets in V200R001 and later versions.

How to bind the IP address, MAC address, and interface
The Switch implements binding between an interface and a MAC address through the traffic policy and DHCP snooping. Then the interface allows only the packets with the bound MAC address and packets matching the DHCP snooping binding table to pass through. The Switch does support binding of IP address + MAC address + interface. For example, to configure Ethernet 0/0/1 to allow only the packets with the source MAC address being 0-02-02 apart from of the packets matching the DHCP snooping binding table, and discard other packets, do as follows: # Enable DHCP snooping globally. [HUAWEI] dhcp snooping enable# Create an ACL that permits only the packets with the source MAC address being 0-02-02. [HUAWEI] acl 4000 [HUAWEI-acl-L2-4000] rule permit source-mac 0-02-02 ffff-ffff-ffff [HUAWEI-acl-L2-4000] rule deny# Create a traffic classifier that matches ACL 4000. [HUAWEI] traffic classifier c1 [HUAWEI-classifier-c1] if-match acl 4000# Create a traffic behavior and a traffic policy. [HUAWEI] traffic behavior b1 [HUAWEI-behavior-b1] permit [HUAWEI] traffic policy p1 [HUAWEI-trafficpolicy-p1] classifier c1 behavior b1# Apply the traffic policy to Ethernet 0/0/1 so that the interface allows only the packets with the source MAC address 0-02-02 to pass through apart from of the packets matching the DHCP snooping binding table. In V100R005C00 and later versions, the configuration is as follows: [HUAWEI] interface Ethernet 0/0/1 [HUAWEI-Ethernet0/0/1] port default vlan 4094 [HUAWEI-Ethernet0/0/1] ip source check user-bind enable [HUAWEI-Ethernet0/0/1] traffic-policy p1 inbound

Can one IP address be bound to multiple MAC addresses in a binding table for IPSG on an S series switch
For S series switches, one IP address cannot be bound to multiple MAC address while one MAC address can be bound to multiple IP addresses. - If you need to bind discontinuous IP addresses to a MAC address, enter 1 to 10 IP addresses in the command. For example, bind IP addresses 10.1.1.2, 10.1.1.5, and 10.1.1.12 to MAC address 0001-0001-0001. [HUAWEI] user-bind static ip-address 10.1.1.2 10.1.1.5 10.1.1.12 mac-address 0001-0001-0001 - If you need to bind continuous IP addresses to a MAC address, enter 1 to 10 IP address segments in the command. The entered IP address segments cannot overlap. For example, bind IP address segments ranging from 10.2.1.1 to 10.2.1.10 and from 10.2.1.20 to 10.2.1.30 to MAC address 0002-0002-0002. [HUAWEI] user-bind static ip-address 10.2.1.1 to 10.2.1.10 10.2.1.20 to 10.2.1.30 mac-address 0002-0002-0002
