Layer	Layer 2, 3 Switching

Spanning Tree Protocol	Standard 802.1d spanning tree support Fast convergence using 802.1w (Rapid Spanning Tree
	[RSTP]),enabled by default Multiple spanning tree instances using 802.1s (MSTP); 16 instances
	Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)

Port grouping/link aggregation	Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)
	Up to 32 groups
	Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad LAG

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.

VLAN	Support for up to 4094 active VLANs simultaneously; port-based and 802.1Q tag-based VLANs;
	MAC-based VLAN Management VLAN Private VLAN with promiscuous, isolated, and community port
	Guest VLAN, unauthenticated VLAN, protocol-based VLAN, IP subnet-based VLAN, CPE VLAN
	Dynamic VLAN assignment using RADIUS server along with 802.1x client authentication

Multicast TV VLAN	Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers
	main in separate VLANs. This feature is also known as Multicast VLAN Registration (MVR).

Unidirectional Link Detection (UDLD)	UDLD monitors physical connection to detect unidirectional links caused by incorrect wiring or port
	faults to prevent forwarding loops and blackholing of traffic in switched networks.

DHCP relay at Layer 2	Relay of DHCP traffic to DHCP server in a different VLAN. Works with DHCP option 82.

IGMP (versions 1, 2, and 3) snooping	Internet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to only the
	equesters; supports 4K 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.

HOL blocking	Head-of-line (HOL) blocking.

IPv4 routing	Wirespeed routing of IPv4 packets, Up to 7K routes and up to 256 IP interfaces

Wirespeed IPv6 static routing	Up to 7K routes and up to 256 IPv6 interfaces

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

CIDR	Support for classless interdomain routing

RIP v2	Support for Routing Information Protocol version 2 for dynamic routing

VRRP	Virtual Router Redundancy Protocol (VRRP) delivers improved availability in a Layer 3 network by
	providing redundancy of the default gateway servicing hosts on the network. VRRP versions 2 and 3 are
	supported. Up to 255 virtual routers are supported

Policy-based routing (PBR)	Flexible routing control to direct packets to different next hop based on IPv4 or IPv6 ACL

DHCP server	Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes.
	Support for DHCP options

DHCP relay at Layer 3	Relay of DHCP traffic across IP domains

User Datagram Protocol (UDP) relay	Relay of broadcast information across Layer 3 domains for application discovery or relaying of
	BOOTP/DHCP packets

Console port	Cisco Standard RJ45 console port

OOB management port	Dedicated Gigabit management port for out-of-band management on SG550XG models

RPS	RPS connector

USB slot	USB Type-A slot on the front panel of the switch for easy file and image management

Buttons	Reset button

Cabling type	Unshielded twisted pair (UTP) Category 5 or better; fiber options (SMF and MMF); coaxial SFP+

LEDs	System, master, fan, RPS, stack ID, link/speed per port

Power	100 - 240V 47 - 63 Hz, internal, universal

Certification	UL (UL 60950), CSA (CSA 22.2), CE mark, FCC Part 15 (CFR 47) Class A
