CBS220 Smart 8-port GE, Ext PS, 2x1G SFP

Model CBS220-8FP-E-2G-EU
● 8 10/100/1000 ports with 130W power budget
● 2 Gigabit SFP

Switching Capacity

Forwarding rate in millions of packets per second (mpps; 64-byte packets)
● 14.88

Switching capacity in Gigabits per second 
● 20

Layer 2 switching

MAC table
● Up to 8,192 Media Access Control (MAC) addresses

Spanning Tree Protocol (STP)
● Standard 802.1d Spanning Tree support, enabled by default Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]) Multiple Spanning Tree instances using 802.1s (MSTP) 16 instances are supported

Port grouping
● Support 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 Load balance based on source and destination MAC address, or source and destination MAC/IP

VLAN
● Support for up to 256 VLANs simultaneously Port-based and 802.1Q tag-based VLANs Management VLAN Guest VLAN

Auto voice VLAN
● Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS

QinQ VLAN
● VLANs 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) blocking
● HOL blocking prevention

Jumbo frame
● Frame sizes up to 9,216 supported

Loopback detection
● Loopback 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 MediaDependent Interface Crossover (MDIX)
● Automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight through) is installed.

Security

ACLs
● Drop 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

QoS

Priority levels
● 8 hardware queues per port

Scheduling
● Strict priority and Weighted Round-Robin (WRR) queue assignment based on DSCP and class of service (802.1p/CoS)

Multicast

Internet Group Management Protocol (IGMP) Versions 1, 2, and 3 Snooping
● IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 256 multicast groups

Management

Web user interface
● Built-in switch configuration utility for easy browser-based device configuration (HTTP/HTTPS). Supports configuration, system dashboard, system maintenance, and monitoring

Remote Monitoring (RMON)
● Embedded RMON software agent supports 4 RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis

Port mirroring
● Traffic on a port or VLAN 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. Four sessions are supported.
