It operates independently of STPLayer 3IPv4 routingWirespeed routing of IPv4 packets Up to 1K static routes and up to 256 IP interfacesIPv6 routingWirespeed routing of IPv6 packetsClassless Interdomain Routing (CIDR)Support for CIDRLayer 3 InterfaceConfiguration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interfaceDHCP relay at Layer 3Relay of DHCP traffic across IP domainsUser Datagram Protocol (UDP) relayRelay of broadcast information across Layer 3 domains for application discovery or relaying of bootP/DHCP packetsDHCP ServerSwitch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes Support for DHCP optionsSecuritySecure Shell (SSH) ProtocolSSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supportedSecure Sockets Layer (SSL)SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switchIEEE 802.1X (Authenticator role)802.1X: RADIUS authentication and accounting, MD5 hash; guest VLAN; unauthenticated VLAN, single/multiple host mode and single/multiple sessions Supports time-based 802.1X Dynamic VLAN assignmentWeb-based authenticationWeb based authentication provides network admission control through web browser to any host devices and operating systemsSTP Bridge Protocol Data Unit (BPDU) GuardA security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that portSTP Root GuardThis prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodesDHCP snoopingFilters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP ServersIP Source Guard (IPSG)When IP Source Guard is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP Address SpoofingDynamic ARP Inspection (DAI)The switch discards ARP packets from a port if there are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination addresses in the ARP packet. This prevents man-in-the-middle attacksIP/MAC/Port Binding (IPMB)The preceding features (DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection) work together to prevent DOS attacks in the network, thereby increasing network availabilitySecure Core Technology (SCT)Makes sure that the switch will receive and process management and protocol traffic no matter how much traffic is receivedSecure Sensitive Data (SSD)A mechanism to manage sensitive data (such as passwords, keys, and so on) securely on the switch, populating this data to other devices, and secure autoconfig. Access to view the sensitive data as plaintext or encrypted is provided according to the user-configured access level and the access method of the userLayer 2 isolation Private VLAN Edge (PVE) with community VLANPVE (also known as protected ports) provides Layer 2 isolation between devices in the same VLAN, supports multiple uplinksPort securityThe ability to lock source MAC addresses to ports and limits the number of learned MAC addressesRADIUS/TACACS+Supports RADIUS and TACACS authentication.
