Auto voice capabilities deliver networkwide zero-touch deployment of voice endpoints and call control devicesMulticast TV VLANMulticast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs. This feature is also known as Multicast VLAN Registration (MVR)VLAN translationSupport for VLAN One-to-One Mapping. In VLAN One-to-One Mapping, on an edge interface, Customer VLANs (C-VLANs) are mapped to service provider VLANs (S-VLANs) and the original C-VLAN tags are replaced by the specified S-VLANQ-in-QVLANs transparently cross over a service provider network while isolating traffic among customersSelective Q-in-QSelective Q-in-Q is an enhancement to the basic Q-in-Q feature and provides, per edge interface, multiple mappings of different C-VLANs to separate S-VLANsSelective Q-in-Q also allows configuration of the EtherType (TPID) of the S-VLAN tagLayer 2 protocol tunneling over Q-in-Q is also supportedGVRP/GARPGeneric VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domainUDLDUnidirectional Link Detection (UDLD) monitors physical connections to detect unidirectional links caused by incorrect wiring or port faults to prevent forwarding loops and blackholing of traffic in switched networksDHCP relay at Layer 2Relay of DHCP traffic to a DHCP server in a different VLAN. Works with DHCP option 82IGMP (versions 1, 2, and 3) snoopingInternet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to only the requesters; it supports 4000 multicast groups (source-specific multicasting is also supported)IGMP querierUsed to support a Layer 2 multicast domain of snooping switches in the absence of a multicast routerHOL blockingHead-Of-Line (HOL) blockingLayer 3IPv4 routingWirespeed routing of IPv4 packetsUp to 990 static routes and up to 128 IP interfacesWirespeed IPv6 static routingUp to 245 static routes and up to 106 IPv6 interfacesLayer 3 interfaceConfiguration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interfaceCIDRSupport for Classless Interdomain Routing (CIDR)DHCP serverSwitch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools and scopesSupport for DHCP optionsDHCP 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 packetsStackingHardware stackUp to four units in a stack. Up to 208 ports managed as a single system with hardware failoverHigh availabilityFast stack failover delivers minimal traffic loss. Supports link aggregation across multiple units in a stackPlug-and-play stacking configuration and managementMaster and backup for resilient stack controlAuto-numberingHot swap of units in stackRing and chain stacking options, auto-stacking port speed, flexible stacking port optionsHigh-speed stack interconnectsCost-effective high-speed 10G fiber and copper interfaces. Support LAG as stacking interconnects for even higher bandwidthHybrid stackA mix of SG350X, SG350XG, and SX350X switches in the same stack (Gigabit and 10 Gigabit Ethernet)SecuritySSHSecure Shell (SSH) is a secure replacement for Telnet traffic. Secure Copy (SCP) also uses SSH. SSH versions 1 and 2 are supportedSSLSecure Sockets Layer (SSL) encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switchIEEE 802.1X (authenticator role)RADIUS authentication and accounting, MD5 hash, guest VLAN, unauthenticated VLAN, single- and multiple-host mode, and single and multiple sessionsSupports time-based 802.1X dynamic VLAN assignmentIEEE 802.1X supplicantA switch can be configured to act as a supplicant to another switch. This enables extended secure access in areas outside the wiring closet (such as conference rooms)Web-based authenticationWeb-based authentication provides Network Admission Control (NAC) through a web browser to any host devices and operating systemsSTP BPDU GuardA security mechanism to protect the networks from invalid configurations. A port enabled for Bridge Protocol Data Unit (BPDU) Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loopsSTP Root GuardPrevents 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 IPSG 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 address in the ARP packet. This prevents man-in-the-middle attacksIP/MAC/Port Binding (IPMB)The preceding features (DHCP snooping, IPSG, and DAI) 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 auto-configuration. Access to view the sensitive data as plain text or encrypted is provided according to the user-configured access level and the access method of the userTrustworthy systemsTrustworthy systems provide a highly secure foundation for Cisco productsRun-time defenses (Executable Space Protection [X-Space], Address Space Layout Randomization [ASLR], Built-In Object Size Checking [BOSC])Image signing and Secure Boot on select models (SG350X-12PMV, SG350X-24PV, SG350X-48PV, and all SX350X models)Private VLANProvides security and isolation between switch ports, which helps ensure that users cannot snoop on other users’ traffic; supports multiple uplinksPort securityProvides the ability to lock source MAC addresses to ports and limit the number of learned MAC addressesRADIUS and TACACS Supports RADIUS and TACACS authentication. Switch functions as a clientRADIUS accountingThe RADIUS accounting functions allow data to be sent at the start and end of services, indicating the amount of resources (such as time, packets, bytes, and so on) used during the sessionStorm controlBroadcast, multicast, and unknown unicastDoS preventionDenial-of-Service (DoS) attack preventionRelated
