Queue assignment based on differentiated services code point (DSCP) and class of service (802.1p/CoS) RIP v2 (on 500X) :Support for Routing Information Protocol version 2, for dynamic routing Hybrid stack (future) :A mix of SF500, SG500, and SG500X in the same stack (10/100, Gigabit, and 10 Gigabit). IPv6 over IPv4 network with ISATAP tunnel support USGv6 and IPv6 Gold Logo certified Layer 2 Switching: Spanning Tree Protocol: Standard 802.1d Spanning Tree Support Fast convergence using 802.1w ([RSTP]), enabled by default Multiple spanning tree instances using 802.1s (MSTP). 16 instances are supported DHCP Relay at Layer 2 :Relay of DHCP traffic to DHCP server in a different VLAN. Works with DHCP Option 82. DHCP Relay at Layer 3 :Relay of DHCP traffic across IP domains. IPv6 applications :Web/SSL, Telnet Server/SSH, Ping, Traceroute, SNTP, TFTP, SNMP, RADIUS, Syslog, DNS client IGMP querier :IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router. Stacking : Hardware stack : Up to 200 ports managed as a single system with hardware failover. Quality of Service: Priority levels 4 hardware queues (8 future) Plug-and-play stacking configuration/management: Master/backup for resilient stack control Auto-numbering Hot swap of units in stack Ring and chain stacking options Auto stacking port speed Flexible stacking port options Class of service: Port based; 802.1p VLAN priority based; IPv4/v6 IP precedence/ToS/DSCP based; DiffServ; classification and re-marking ACLs, Trusted QoS CIDR : Support for Classless Inter-Domain Routing Mixed stacking support :A stack can consist of a mix of SF500 and SG500 models (mix of 10/100 and Gigabit in the same stack). IPv6: IPv6 Host Mode IPv6 over Ethernet Dual IPv6/IPv4 stack IPv6 Neighbor and Router Discovery (ND) IPv6 Stateless Address Autoconfiguration Path MTU Discovery Duplicate Address Detection (DAD) ICMPv6 Management: Firmware upgrade: • Web browser upgrade (HTTP/HTTPS) and TFTP and SCP • Upgrade can be initiated through console port as well • Dual images for resilient firmware upgrades Localization :Localization of GUI and documentation into multiple languages. Login banner :Configurable login banners for web as well as CLI. VLAN mirroring:Traffic from a VLAN can be mirrored to a port for analysis with a network analyzer or RMON probe. Up to 8 source VLANs can be mirrored to one destination port. Other management:Traceroute; single IP management; HTTP/HTTPS; SSH; RADIUS; port mirroring; TFTP upgrade; DHCP client; BOOTP; Simple Network Time Protocol (SNTP); Xmodem upgrade; cable diagnostics; Ping; syslog; Telnet client(SSH secure support) Autoconfiguration with Secure Copy (SCP) file download :Enables secure mass deployment with protection of sensitive data. SNMP Smartports : Simplified configuration of QoS and security capabilities. IPv4 and IPv6 Dual Stack Secure Copy (SCP) :Securely transfer files to and from the switch. Textview CLI :Scriptable CLI. A full CLI as well as a menu CLI is supported. Cloud Services Support for Cisco Small Business and Cisco OnPlus. Port mirroring:Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe. Up to 8 source ports can be mirrored to one destination port. Time-based port operation :Link up or down based on user-defined schedule (when the port is administratively up). DHCP (Options 12, 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), DHCP Relay, and host name. Web user interface Automatic time settings from Management Station. Text-editable configs :Config files can be edited with a text editor and downloaded to another switch, facilitating easier mass deployment. RMON Auto Smartports :Automatically 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. Securitate: 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.This prevents man-in-the-middle attack SSH : SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH versions 1 and 2 are supported. Congestion avoidance A TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization. Secure Sensitive Data (SSD) IEEE 802.1X (Authenticator role): 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 assignment ACLs : Support for up to 2000 rules on 500 Series and 3000 on 500X series. Time-based ACLs supported. Port security : Ability to lock MAC addresses to ports, and limit the number of learned MAC addresses. STP Root Guard:Prevents 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. RADIUS accounting IP Source Guard (IPSG):This prevents IP Address Spoofing. DoS prevention : DoS attack prevention. Secure Core Technology (SCT):Ensures that the switch will receive and process management and protocol traffic no matter how much traffic is received. SSL : Secure Sockets Layer (SSL) encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch. Multiple user privilege levels in CLI Levels 1, 7, and 15 privilege levels. Layer 2 isolation (PVE) with community VLAN*:Private VLAN Edge provides security and isolation between switch ports, which helps ensure that users cannot snoop on other users' traffic; supports multiple uplinks. STP BPDU Guard: A 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 loops. RADIUS/TACACS+ : Supports RADIUS and TACACS authentication. Switch functions as a client. DHCP snooping:Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as a DHCP Server. Storm control :Broadcast, multicast, and unknown unicast. Conectivitate: Cabling type Unshielded twisted pair (UTP) Category 5 or better; Fiber options (SMF and MMF); Coaxial SFP+ for stacking purposes 48GE + 4 10GE
