What kind of security of switches provided or supported?
There are two ways to use a switch to improve network security: VLAN: A network administrator can define several VLANs and block access to each VLAN to prevent users from accessing servers for which they don’t have access permission. Mac address filtering: A network administrator can define a DA (Destination Address) so that packets can only be received from port A (a hub) and only allow those same packets to be forwarded to port B (a server connection, for example). Using MAC address filtering, only users that are connected to port A can access the server connected to port B, other packets from other ports, even those whose DA is for the server on port B, will be dropped.
