Port Security
Combines and extends IEEE 802.1X and MAC authentication to provide MAC-based network access control
• ARP attack protection
The ARP detection feature enables access devices to block ARP packets from unauthorized clients to prevent user
spoofing and gateway spoofing attacks.
• Automatic VLAN assignment
assigns users automatically to the appropriate VLAN based on their identity, location and time of day
• STP BPDU port protection
blocks Bridge Protocol Data Units (BPDUs) on ports that do not require BPDUs, preventing forged BPDU attacks
• STP root guard
protects the root bridge from malicious attacks or configuration mistakes
• Automatic denial-of-service protection
monitors for malicious attacks and protects the network by blocking the attacks
• Management password
provides security so that only authorized access to the Web browser interface is allowed
Performance
• Half- and full-duplex auto-negotiating capability on every port
doubles the throughput on every port
• Selectable queue configurations
allows for increased performance by selecting the number of queues and associated memory buffering that best meet the
requirements of the network applications
• IGMP snooping
improves network performance through multicast filtering, instead of flooding traffic to all ports
• Fiber uplink
provides greater distance connectivity using Gigabit Ethernet fiber uplinks
Layer 2 switching
• Spanning Tree Protocol (STP)
supports standard IEEE 802.1D STP, IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) for faster convergence, and
IEEE 802.1s Multiple Spanning Tree Protocol (MSTP)
• BPDU filtering
drops BPDU packets when STP is enabled globally but disabled on a specific port
• Jumbo frame support
supports up to 10 kilobyte frame size to improve the performance of large data transfers
• VLAN support and tagging
supports IEEE 802.1Q with 4,094 simultaneous VLAN IDs
Layer 3 services
• Address Resolution Protocol (ARP)
determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection
of duplicate IP addresses; proxy ARP allows normal ARP operation between subnets or when subnets are separated by a
Layer 2 network
• DHCP relay
simplifies management of DHCP addresses in networks with multiple subnets
Layer 3 routing
• Static IPv4/IPv6 routing
