Auto voice capabilities deliver network-wide zero touch deployment of voice endpoints and call control devices. Multicast TV VLANMulticast VLAN used for video applications. Q-in-QVLANs transparently cross over a service provider network while isolating traffic among customers. GVRP/GARPGeneric VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domain. DHCP Relay at Layer 2Relay of DHCP traffic to DHCP server in a different VLAN. Works with DHCP Option 82. IGMP (versions 1, 2, and 3) snoopingInternet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to only the requesters;supports 1000 multicast groups (source-specific multicasting is also supported). IGMP querierIGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router. HOL blockingHead-of-line (HOL) blocking. Layer 3IPv4 routingWirespeed routing of IPv4 packetsUp to 128 static routes and up to 128 IP interfacesCIDRSupport for Classless Inter-Domain RoutingRIP v2 (on 500X)Support for Routing Information Protocol version 2, for dynamic routingVRRP (on 500X)Virtual Router Redundancy Protocol (VRRP) delivers improved availability in a Layer 3 network by providing redundancy of the default gateway servicing hosts on the network. VRRP versions 2 and 3 are supported. Up to 255 virtual routers are supported. DHCP Relay at Layer 3Relay of DHCP traffic across IP domains. User Datagram Protocol (UDP) RelayRelay of broadcast information across Layer 3 domains for application discovery or relaying of BOOTP/DHCP packets. StackingHardware stackUp to 200 ports managed as a single system with hardware failover. High availabilityFast stack failover delivers minimal traffic loss. Plug-and-play stacking configuration/managementMaster/backup for resilient stack controlAuto-numberingHot swap of units in stackRing and chain stacking optionsAuto stacking port speedFlexible stacking port optionsHigh-speed stack interconnectsCost-effective 5G copper and high-speed 10G Fiber and Copper interfaces. Mixed stacking supportA stack can consist of a mix of SF500 and SG500 models (mix of 10/100 and Gigabit in the same stack). Hybrid stack (future)A mix of SF500, SG500, and SG500X in the same stack (10/100, Gigabit, and 10 Gigabit). SecuritySSHSecure Shell (SSH) Protocol secures Telnet traffic to and from the switch. SSH versions 1 and 2 are supported. SSLSecure Sockets Layer (SSL) encrypts all HTTPS traffic, allowing secure access to the browser-based managementUI in the switch. IEEE 802.1X (Authenticator role)RADIUS authentication and accounting, MD5 hash, guest VLAN, unauthenticated VLAN, single/multiple host mode and single/multiple sessionsSupports time-based 802.1XDynamic VLAN assignmentSTP 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. STP Root GuardPrevents a port from being selected as a root port, effectively preventing bridges in the LAN segment connected to the port from being a root bridge. DHCP snoopingFilters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. IP 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. Dynamic ARP Inspection (DAI)The switch discards ARP packets from a port if there is no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination address in the ARP packet. Secure Core Technology (SCT)Ensures that the switch will receive and process management and protocol traffic no matter how much traffic is received. Layer 2 isolation (PVE) with community VLAN*Provides Layer 2 isolation between devices in the same VLAN; supports multiple uplinks. Port securityAbility to lock MAC addresses to ports, and limit the number of learned MAC addresses. RADIUS/TACACS+Supports RADIUS and TACACS authentication. Switch functions as a client. RADIUS 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 session. Storm controlBroadcast, multicast, and unknown unicast. DoS preventionDoS attack prevention. Congestion avoidanceA TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization. Multiple user privilege levels in CLILevels 1, 7, and 15 privilege levels.

Up to 8 source ports can be mirrored to one destination port. VLAN mirroringTraffic from a VLAN can be mirrored to a port for analysis with a network analyzer or RMON probe. Up to 8 source LANs can be mirrored to one destination port. DHCP (Options 66, 67, 82, 129, and 150)DHCP options facilitate tighter control from a central point (DHCP Server), to obtain IP address, auto configuration with configuration file download, and DHCP relay. Autoconfiguration with Secure Copy (SCP) file downloadEnables secure mass deployment with protection of sensitive data. Text-editable configsConfig files can be edited with a text editor and downloaded to another switch, facilitating easier mass deployment. SmartportsSimplified configuration of QoS and security capabilities. Auto SmartportsAutomatically applies the intelligence delivered through the Smartports roles to the port based on the devices discovered over Cisco Discovery Protocol or LLDP-MED. This facilitates zero touch deployments. Cisco Configuration Assistant ManagementManage devices from Cisco Configuration Assistant Management application.

Reduces the power consumption for cable shorter than 10m. supported on Gigabit Ethernet models. EEE compliant (802.3az)Supports IEEE 802.3az on all Gigabit copper ports. GeneralJumbo framesFrame sizes up to 10K. Bare supported on 10/100 and Gigabit Ethernet interfaces. The default MTU is 2K. MAC table16,000 MAC addresses. DiscoveryBonjourThe switch advertises itself using the Bonjour protocol. LLDP (802.1ab) with LLDP-MED extensionsLink Layer Discovery Protocol (LLDP) allows the switch to advertise its identification, configuration, and capabilities to neighboring devices that store the data in a MIB. LLDP-MED is an enhancement to LLDP that adds the extensions needed for IP phones. Cisco Discovery ProtocolThe switch advertises itself using the Cisco Discovery Protocol (CDP). It also learns the connected device and its characteristics via CDP.
