SSH versions 1 and 2 are supported. , Congestion avoidance A TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization. , RADIUS accounting The 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. , Layer 2 isolation (PVE) with community VLAN , Dynamic ARP Inspection (DAI) prevents man-in-the-middle attacks. , 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 , Multiple user privilege levels in CLI Levels 1, 7, and 15 privilege levels. , SSL Secure Sockets Layer (SSL) encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch. , Storm control Broadcast, multicast, and unknown unicast. , Port security Ability to lock MAC addresses to ports, and limit the number of learned MAC addresses. , Secure Core Technology (SCT) Ensures that the switch will receive and process management and protocol traffic no matter how much traffic is received. , 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. , ACLs Support for up to 2000 rules on 500 Series and 3000 on 500X series. , 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 assignment , DoS prevention DoS attack prevention. , RADIUS/TACACS+ Supports RADIUS and TACACS authentication. Switch functions as a client. , Secure Sensitive Data (SSD) , 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 , 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. , Capacity in mpps (64-byte packets) :9.52 , Switching Capacity (Gbps) : 28.8 , Layer 2 Switching :Spanning Tree Protocol :Standard 802.1d Spanning Tree Support Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default , GVRP/GARP Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domain. , High availability Fast stack failover delivers minimal traffic loss. , DHCP Relay at Layer 3 Relay of DHCP traffic across IP domains. , Rate limiting Ingress policer; egress shaping and ingress rate control; per VLAN, per port, and flow based , CIDR Support for Classless Inter-Domain Routing , Scheduling Strict Priority and weighted round-robin (WRR) , HOL blocking Head-of-line (HOL) blocking. , 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. , 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 options , User Datagram Protocol (UDP) Relay Relay of broadcast information across Layer 3 domains for application discovery or relaying of BOOTP/DHCP packets. , RIP v2 (on 500X) Support for Routing Information Protocol version 2, for dynamic routing , 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 , Jumbo Frames Frames up to 10K in length. , Port grouping/link aggregation:Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP) :Up to 8 groupsUp to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad LAG , IGMP (versions 1, 2, and 3) snooping Internet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to only the requesters; supports 1000 multicast groups (source-specific multicasting is also supported). , Q-in-Q VLANs transparently cross over a service provider network while isolating traffic among customers. , High-speed stack interconnects Cost-effective 5G copper and high-speed 10G Fiber and Copper interfaces. , Stacking:Hardware stack Up to 200 ports managed as a single system with hardware failover. , VRRP (on 500X) VRRPdelivers 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. , Queue assignment based on differentiated services code point (DSCP) and class of service (802.1p/CoS) , Layer 3:IPv4 routing Wirespeed routing of IPv4 packets Up to 128 static routes and up to 128 IP interfaces , Quality of Service Priority levels 4 hardware queues (8 future) , IGMP querier IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router. , Voice VLAN , Protocol-based VLAN , PVE (Private VLAN Edge), also known as Protected Port, with multiple uplinks , Port-based and 802.1Q tag-based VLANs , Multicast TV VLAN , CPE VLAN , Guest VLAN , MAC-based VLAN , Dynamic VLAN assignment via Radius server along with 802.1x client authentication , Unauthenticated VLAN , Management VLAN , Support for up to 4096 VLANs simultaneously - sf500-24p-k9-g5
