User’s Manual of GS-5220-48T4X 1. INTRODUCTION PLANET L2+ 48-Port 10/100/1000Mbps + 4-Port Shared SFP + 4-Port 10G SFP+ Managed Switch with Hardware Layer3 IPv4/IPv6 Static Routing, GS-5220-48T4X, comes with the multi-port Gigabit Ethernet Switch and SFP fiber optic connectibility and robust layer 2 features. “Managed Switch” is used as an alternative name in this user’s manual.
Page 10: Product Description
IPv6 / IPv4 Dual Stack Supporting both IPv6 and IPv4 protocols, the GS-5220-48T4X helps the SMBs to step in the IPv6 era with the lowest investment as its network facilities need not to be replaced or overhauled if the IPv6 FTTx edge network is set up.
Page 11 Powerful Security The GS-5220-48T4X offers a comprehensive layer 2 to layer 4 Access Control List (ACL) for enforcing security to the edge. It can be used to restrict network access by denying packets based on source and destination IP address, TCP/UDP ports or defined typical network applications.
Page 12 SNMP protocol. For reducing product learning time, the GS-5220-48T4X offers Cisco-like command via Telnet or console port and customer doesn’t need to learn new command from these switches. Moreover, the GS-5220-48T4X offers secure remote management by supporting SSH, SSL and SNMPv3 connection which encrypt the packet content at each session.

User’s Manual of GS-5220-48T4X 4.5 Link Aggregation Port Aggregation optimizes port usage by linking a group of ports together to form a single Link Aggregated Groups (LAGs). Port Aggregation multiplies the bandwidth between the devices, increases port flexibility, and provides link redundancy.
Page 91 User’s Manual of GS-5220-48T4X The Link Aggregation Control Protocol (LACP) provides a standardized means for exchanging information between Partner Systems that require high speed redundant links. Link aggregation lets you group up to eight consecutive ports into a single dedicated connection. This feature can expand bandwidth to a device on the network. LACP operation requires full-duplex mode, more detail information refer to the IEEE 802.3ad standard.

User’s Manual of GS-5220-48T4X 4.6.2 IEEE 802.1Q VLAN In large networks, routers are used to isolate broadcast traffic for each subnet into separate domains. This Managed Switch provides a similar service at Layer 2 by using VLANs to organize any group of network nodes into separate broadcast domains.

User’s Manual of GS-5220-48T4X ■ 802.1Q VLAN Tags The figure below shows the 802.1Q VLAN tag. There are four additional octets inserted after the source MAC address. Their presence is indicated by a value of 0x8100 in the Ether Type field. When a packet's Ether Type field is equal to 0x8100, the packet carries the IEEE 802.1Q/802.1p tag.
Page 101: Default Vlans
User’s Manual of GS-5220-48T4X Every physical port on a switch has a PVID. 802.1Q ports are also assigned a PVID, for use within the switch. If no VLAN are defined on the switch, all ports are then assigned to a default VLAN with a PVID equal to 1. Untagged packets are assigned the PVID of the port on which they were received.

The disadvantage is that MAC addresses can be spoofed by malicious users, equipment whose MAC address is a valid RADIUS user can be used by anyone, and only the MD5-Challenge method is supported.

Authentication Initiation and Message Exchange  The switch or the client can initiate authentication. If you enable authentication on a port by using the dot1x port-control auto interface configuration command, the switch must initiate authentication when it determines that the port link state transitions from down to up.
Page 215: Authentication Configuration
User’s Manual of GS-5220-48T4X Ports in Authorized and Unauthorized States  The switch port state determines whether or not the client is granted access to the network. The port starts in the unauthorized state. While in this state, the port disallows all ingress and egress traffic except for 802.1X protocol packets. When a client is successfully authenticated, the port transitions to the authorized state, allowing all traffic for the client to flow normally.

Page 221 User’s Manual of GS-5220-48T4X packets also encapsulate EAP PDUs together with other attributes like the switch's IP address, name, and the supplicant's port number on the switch.

In this mode, the Port Security module is used to secure a supplicant's MAC address once successfully authenticated.

Page 223 User’s Manual of GS-5220-48T4X the 802.1X standard. The advantage of MAC-based authentication over port-based 802.1X is that several clients can be connected to the same port (e.g. through a 3rd party switch or a hub) and still require individual authentication, and that the clients don't need special supplicant software to authenticate.

If present and valid, the port's Port VLAN ID will be changed to this VLAN ID, the port will be set to be a member of that VLAN ID, and the port will be forced into VLAN unaware mode.
