Security features that keep the network in order
IP-MAC-Port-VID binding, port security, storm control and DHCP snooping protect the network against broadcast storms and ARP attacks. ACLs restrict access by MAC or IP address, TCP/UDP port or VLAN ID, and 802.1X with a RADIUS server lets only authenticated devices onto the network. Voice VLAN and QoS give IP phones and video priority, while the two SFP slots allow a fibre link to another floor or building.
