24 10/100/1000 ports

4 Gigabit SFP

Rack-mountable



- Jumbo frames Frame: sizes up to 9K bytes. The default MTU is 2K bytes

- MAC table: 8K addresses

- Switching capacity in gigabits per second (Gbps): 56 Gbps

Layer 2 switching

- Spanning Tree Protocol (STP):

. Standard 802.1d spanning tree support

. Fast convergence using 802.1w (Rapid Spanning Tree Protocol [RSTP]), enabled by default

. Multiple spanning tree instances using 802.1s (MSTP); 8 instances are supported

. Per-VLAN Spanning Tree Plus (PVST+); 126 instances are supported

. Rapid PVST+ (RPVST+); 126 instances are supported

- Port grouping/link aggregation:

Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)

● Up to 4 groups

● Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad Link Aggregation Group (LAG)

- VLAN:

. Support for up to 255 active VLANs simultaneously

. Port-based and 802.1Q tag-based VLANs

. Management VLAN

. Guest VLAN

- Voice VLAN: Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS. Voice Services Discovery Protocol (VSDP) delivers networkwide zero-touch deployment of voice endpoints and call control devices

- Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP): Protocols for automatically propagating and configuring VLANs in a bridged domain

- IGMP (versions 1, 2, and 3) snooping: Internet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to only the requesters; supports 255 multicast groups (source-specific multicasting is also supported)

- IGMP querier : Used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router

- HOL blocking: Head-of-Line (HOL) blocking prevention

- 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

- Unit dimensions: 445 x 240 x 44 mm

- Unit weight: 2.63kg
