802.1X provides port-based authentication, which involves communication between a supplicant, authenticator,
and authentication server. Port refers to a single point of attachment to the LAN infrastructure. Supplicant is often
software on a client device, such as a laptop; authenticator is a network device, such as an Ethernet switch or
wireless access point; authentication server is typically a host running software supporting the RADIUS and EAP
protocols.
Port-based Network access control (PNAC) ensures that all the users are authorized before being granted an
access to the network. User authentication is carried out using any standard-based RADIUS server.
802.1X Configuration
Mode: Enables or disables 802.1X globally for all ports. The 802.1X protocol should be enabled globally
for the switch before the port settings are active (Default: Disabled)
RADIUS IP: Address of authentication server
RADIUS UDP Port: Network port of authentication server used for authentication messages (Range: 1-
65535; Default: 1812)
RADIUS Secret: Sets the text string used for encryption between the switch and the RADIUS server. This
key is used to authenticate logon access for the client. Do not use blank spaces in the string. (Max. length:
48 characters).
IGMP Snooping
IGMP Snooping is the process of listening to IGMP network traffic. IGMP Snooping allows a layer 2 switch to
“listen in” on the IGMP conversation between hosts and routers by processing the layer3 IGMP packets sent in a
multicast network.
When IGMP Snooping is enabled, it analyzes all IGMP packets between hosts connected to the switch and
multicast routers in the network. When a switch hears an IGMP report from a host for a given multicast group, the
switch adds the host’s port number to the multicast list for that group. When the switch hears an IGMP Leave, it
removes the host’s port from the table entry. It prevents flooding of IP multicast traffic, and limits bandwidth
intensive video traffic to the subscribers only.
IGMP Configuration
IGMP Enabled: When enabled, the switch monitors network traffic to determine which hosts want to
receive multicast traffic.
Router Ports: Set if ports are connecting to the IGMP administrative routers.
