Switch Cisco SF220-48 48-Port (SF220-48-K9)

Switch Cisco SF220-48 48-Port (SF220-48-K9)

48 10/100 Mbps ports; 2 Combo mini-GBIC ports.
Performance: Switching capacity 13.6 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).
