Cisco 48 Port Gigabit + 2 SFP Managed Switch / SG350-52

SG350-52 Specification

Feature

Description

Spanning Tree Protocol (STP)

• Standard 802.1d Spanning Tree support

• Fast convergence using 802.1w or Rapid Spanning Tree (RSTP), enabled by default

• 8 instances are supported

• Multiple Spanning Tree instances using 802.1s (MSTP)

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

Virtual Local Area Network (VLAN)

• Support for up to 4096 VLANs simultaneously

• Port-based and 802.1Q tag-based VLANs

• Media Access Control (MAC)-based VLAN

• Management VLAN

• Private VLAN Edge (PVE), also known as protected ports, with multiple uplinks

• Guest VLAN

• Unauthenticated VLAN

• Dynamic VLAN assignment via RADIUS server along with 802.1x client authentication

• Customer Premises Equipment (CPE) VLAN

Voice VLAN

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

• Auto voice capabilities deliver networkwide zero-touch deployment of voice endpoints and call control devices.

Multicast TV VLAN

Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs, also known as Multicast VLAN Registration(MVR)

Q-in-Q 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

Unidirectional Link Detection (UDLD)

UDLD monitors physical connection to detect unidirectional links caused by incorrect wiring or cable/port faults to prevent forwarding loops and blackholing of traffic in switched networks

Dynamic Host Configuration Protocol (DHCP) Relay at Layer 2

Relay of DHCP traffic to DHCP server in different VLAN; works with DHCP Option 82

Internet Group Management Protocol (IGMP) versions 1, 2, and 3 snooping

IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 1K multicast groups (source-specific multicasting is also supported)

IGMP Querier

IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router

Head-of-Line (HOL) Blocking

HOL blocking prevention

Jumbo Frame

Up to 9K (9216) bytes

IPv4 routing

Wirespeed routing of IPv4 packets

Up to 512 static routes and up to 128 IP interfaces

Classless Interdomain Routing (CIDR)

Support for CIDR

Layer 3 Interface

Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface
