Switch Cisco SG220-26 26-port (SG220-26-K9)

Switch Cisco SG220-26 26-port (SG220-26-K9)

24-port Gigabit; 2 Combo mini-GBIC ports.
Performance: Switching capacity 52 Gbps.
Layer 2: Port grouping up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation, Support for up to 256 VLANs simultaneously (out of 4096 VLAN IDs), Head-of-line (HOL) blocking HOL blocking prevention.
Internet Group Management Protocol(IGMP) versions 1 and 2 snooping: IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 256 multicast groups.
QoS: Priority levels 4 : hardware queues, Scheduling: Priority queuing and weighted round-robin (WRR), Queue assignment based on DSCP and class of service (802.1p/CoS).

Layer 2 Switching
Spanning Tree Protocol (STP)Standard 802.1d STP support
Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default
Port groupingSupport for IEEE 802.3ad Link Aggregation Control Protocol (LACP): Up to 8 groups, Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation
VLANSupport for up to 256 VLANs simultaneously
Port-based and 802.1Q tag-based VLANs
Management VLAN
Guest VLAN
Auto voice VLANVoice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS
QinQ VLANVLANs transparently cross a service provider network while isolating traffic among customers
Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP)Protocols for automatically propagating and configuring VLANs in a bridged domain
Head-Of-Line (HOL) blockingHOL blocking prevention
Loopback detectionLoopback detection provides protection against loops by transmitting loop protocol packets out of ports on which loop protection has been enabled. It operates independently of STP.
Automatic Media-Dependent Interface Crossover (MDIX)Automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight-through) is installed.
Security
ACLsDrop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, Differentiated Services Code Point (DSCP)/IP precedence, TCP/UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag
Support up to 512 rules
Port securityCreates the ability to lock source MAC addresses to ports; limits the number of learned MAC addresses
IEEE 802.1X (authenticator role)802.1X: RADIUS authentication; guest VLAN;
RADIUS, TACACS+Supports RADIUS and TACACS authentication; switch functions as a client
MAC address filteringSupported
Storm controlBroadcast, multicast, and unknown unicast
DoS protectionDOS attack prevention
STP Bridge Protocol Data Unit (BPDU) GuardThis security mechanism protects the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port
Spanning Tree Loop GuardThis feature provides additional protection against Layer 2 forwarding loops (STP loops).
Secure Shell (SSH) ProtocolSSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported
Secure Sockets Layer (SSL)SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch
Quality of Service
Priority levels8 hardware queues
SchedulingStrict priority and weighted round-robin (WRR)
Queue assignment based on differentiated services code point (DSCP) and class of service (802.1p/CoS)
Class of servicePort based, 802.1p VLAN priority based, IPv4/v6 IP precedence/type of service (ToS)/DSCP based, Differentiated Services (DiffServ)
