Dynamic Host Configuration Protocol (DHCP) Layer 2 relay: Forwarding DHCP traffic to a DHCP server on different VLANs, Works with DHCP Option 82 Internet Group Management Protocol (IGMP) versions 1, 2, and 3 (snooping): IGMP restricts bandwidth-intensive multicast traffic to supplicants only Supports 1K multicast groups/source-specific multicast GMP Querier: IGMP Querier is used to support layer 2 multicast domain switch tracking in the absence of a multicast router Loopback Detection: Provides loopback protection by forwarding protocol packets from ports on which loop protection is enabled, operates independently of STP Layer 3: IPv4: Wirespeed routing of IPv4/static packets up to 1K routes and up to 128 IPv6 IP interfaces: Wirespeed routing of IPv6 packets Classless Inter-Domain Routing (CIDR) Layer 3 interface configuration on physical port, LAG, VLAN/loopback interface DHCP traffic relaying over IP addresses Protocol relaying custom x datagram (UDP): Relay broadcast information in layer 3 domains for application discovery or forwarding of bootP/DHCP packets DHCP server: The switch acts as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes Supports DHCP options Quality of Service: Layers Priority: 8 hardware queues Scheduling: Strict priority and Weighted Round-Robin (WRR)/Queuing based on DSCP and Class of Service (802.1p/CoS) Class of Service: Port

without any packet loss when the switch detects connection resumes Cable length detection: adjusts signal strength based on cable length/reduces power consumption for cables shorter than 10m LEDs can be manually turned off to save power Detection: The switch advertises itself using Bonjour protocol Link Level Detection Protocol (LLDP) (802.1 ab) with LLDP-MED extensions: LLDP allows the switch to advertise its identity, configuration, and capabilities to neighboring devices that store data in the MIB LLDP-MED is an enhancement to LLDP that adds extensions required for IP phones The product advertises itself using the Cisco protocol Discovery and through it learns the connected device, its Power over Ethernet (PoE) characteristics: Supports 802.3at PoE+, 802.3af Maximum power of 60W on

single/multi-host mode, and single/multi-session Supports transient 802.1X Purpose dynamic VLAN Web Authentication: Web Authentication provides network access control through a web browser on any Former Host Devices and Operating Systems STP Protocol Packet Security (BPDU): A security mechanism to protect the network from invalid configurations A port enabled for BPDU security is disabled if a BPDU message is received on that port to network administrator control, become Spanning Tree Protocol root nodes DHCP Snooping: Filters DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces Prevents rogue devices from acting as DHCP servers IP Source Guard (IPSG): When IP Source Guard is enabled on a port, the Switch drops IP packets received from the port unless the source IP addresses of the packets have been statically configured or dynamically learned from DHCP snooping. This prevents IP address spoofing Dynamic ARP Inspection (DAI): The switch drops ARP packets from a port if there are no static or dynamic IP/MAC bindings, or if there is a discrepancy between source/destination addresses in an ARP packet. This prevents man-in-the-middle attacks IP/MAC/Port Binding (IPMB): DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection work together to prevent DOS attacks on the network, thereby increasing network availability Secure Core Technology (SCT): Provides control switch to receive and handle protocol traffic no matter how much traffic is received Secure Sensitive Data (SSD): A mechanism to manage sensitive data (such as passwords, keys), populate this data on other devices, and protect autoconfig Access to view sensitive data in the form of an open /ciphertext is provided according to user's access level/method Layer 2 Private Edge VLAN (PVE) isolation with community VLAN: PVE (also known as secure ports) provides layer 2 isolation between devices in the same VLAN, supports multiple uplinks Security Ports: Ability to block source MAC addresses in RADIUS/TACACS+: Supports RADIUS and TACACS+ authentication Switch operates as a client Storm control: Broadcast, multicast, and unknown unicast , bytes) used during a session DoS: Prevention of Denial of Service (DOS) Access Control Lists ACLs: Support for up to 512 rules Limit or rate limit based on source/destination MAC address, VLAN ID/IP address, protocol, port , Differentiated Services Code Points (DSCP), TCP/UDP Source and Destination Ports, 802.1p Priority, Ethernet Type, Control over Internet Protocol (ICMP) Messages, IGMP Packets, TCP Flag, ACLs Supported with Timed
