SI and EI ports in the same section of the switch are the same. What is the difference?

First, the difference between the SI port and the EI port in the same section of the switch:

1), which supports protocol-based VLAN；; ;

2) Support VoiceVLAN.

3) Support the configuration of user IP+MAC address+port combination binding;

4) Support DLDP (Device Link Detection Protocol);

5) Support configuration to prohibit VLAN from learning MAC address;

6) Support the rapid deployment of EAD (Endpoint Access Defense);

7) Support the application of Option82; In DHCP snooping function;

8) Support basic/advanced ACL (the basic/advanced ACL defined on S 3100-Si series switches can only be used when it is referenced by upper-level software and cannot be assigned to hardware; Acls defined on S3 100-EI series switches can be referenced by upper software and sent to hardware);

9), support layer 2 ACL；;

10), which supports QoS profile;

1 1), supporting SSH 1 version;

12), which supports VLAN mapping; ;

13, supporting BPDU tunnel; ;

14, supporting flexible QinQ；;

15, which supports IPv6 address configuration;

16, supporting Ping, Traceroute, TFTP and Telnet applications based on IPv6;

Support dynamic domain name resolution;

18, supporting intelligent link; ;

19, which supports monitoring links; ;

20. Support multi-service VLAN planning;
