Port Aggregation multiplies the bandwidth between the devices, increases port flexibility, and provides link redundancy. Each LAG is composed of ports of the same speed, set to full-duplex operations.
Page 104 User’s Manual of IGS-5227-Series 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.

Page 112: Ieee 802.1Q Vlan
User’s Manual of IGS-5227-Series 4.6.2 IEEE 802.1Q VLAN In large networks, routers are used to isolate broadcast traffic for each subnet into separate domains. This Industrial Managed Switch provides a similar service at Layer 2 by using VLANs to organize any group of network nodes into separate broadcast domains.
Page 113 User’s Manual of IGS-5227-Series ■ 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 114 User’s Manual of IGS-5227-Series 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.

User’s Manual of IGS-5227-Series ■ Port Overlapping Port overlapping can be used to allow access to commonly shared network resources among different VLAN groups, such as file servers or printers.

Authentication Initiation and Message Exchange  The switch or the client can initiate authentication.

User’s Manual of IGS-5227-Series 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 237 User’s Manual of IGS-5227-Series MD5-Challenge, PEAP, and TLS. The important thing is that the authenticator (the switch) doesn't need to know which authentication method the supplicant and the authentication server are using, or how many information exchange frames are needed for a particular method. The switch simply encapsulates the EAP part of the frame into the relevant type (EAPOL or RADIUS) and forwards it.

Multi 802.1X Multi 802.1X is - like Single 802.1X - not an IEEE standard, but a variant that features many of the same characteristics. In Multi 802.1X, one or more supplicants can get authenticated on the same port at the same time. Each supplicant is authenticated individually and secured in the MAC table using the Port Security module.
Page 239 User’s Manual of IGS-5227-Series 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.
