    1.1.4 VLAN Interface Hosts in different VLANs cannot communicate with each other directly unless routers or Layer 3 switches are used to do Layer 3 forwarding. The S3100-52P Ethernet switch supports VLAN interfaces configuration to forward packets in Layer 3.

  • Page 6: Vlan Classification

    1.2.1 Link Types of Ethernet Ports The link type of an Ethernet port on the S3100-52P can be one of the following: Access: An access port can belong to only one VLAN, and is generally connected to a user PC.

    Supported (0x809B) 1.3.5 Implementation of Protocol-Based VLAN S3100-52P Ethernet switch assigns the packet to the specific VLAN by matching the packet with the protocol template. The protocol template is the standard to determine the protocol to which a packet belongs. Protocol templates include standard templates and user-defined templates: The standard template adopts the RFC-defined packet encapsulation formats and values of some specific fields as the matching criteria.

    The operation of enabling/disabling a VLAN’s VLAN interface does not influence the physical status of the Ethernet ports belonging to this VLAN. An S3100-52P switch can be configured with a single VLAN interface only, and the VLAN must be the management VLAN. For details about the management VLAN, refer to the “Stack-Cluster Configuration”...

    1/0/10 on the S3100-52P switch. IP network and AppleTalk network workstations (hosts) coexist in the Workroom. The S3100-52P switch connects to VLAN 100 (using IP network) through Ethernet 1/0/11 and to VLAN 200 (using AppleTalk network) through Ethernet 1/0/12. Configure the switch to automatically assign the IP and AppleTalk packets to proper VLANs for transmission, so as to ensure the normal communication between the workstations and servers.
