	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
	VLAN:
	Support for up to 256 VLANs simultaneously (out of 4096 VLAN IDs)
	Port-based and 802.1Q tag-based VLANs
	MAC-based VLAN
	Management VLAN
	Private VLAN Edge (PVE), also known as protected ports, with multiple uplinks
	Guest VLAN
	Unauthenticated VLAN
	Voice Lan:
	Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS
	Generic VLAN Registration Protocol (GVRP)/ Generic Attribute Registration Protocol (GARP):
	Protocols for automatically propagating and configuring VLANs in a bridged domain
	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 256 multicast groups (source-specific multicasting is also supported)
	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
Layer 3	IPv4 Routing: Wirespeed routing of IPv4 packets Up to 32 static routes and up to 32 IP interfaces Classless Inter-Domain Routing (CIDR): Support for CIDR 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
Security	Secure Shell Protocol (SSH): SSH secures Telnet traffic to and from the switch; SSH v1 and v2 are supported
	Secure Sockets Layer (SSL): SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch
	IEEE 802.1X (Authenticator role): RADIUS authentication and accounting, MD5 hash; guest VLAN; unauthenticated VLAN, single/multiple host mode and single/multiple sessions
	Supports time-based 802.1X
	Dynamic VLAN assignment
	Layer 3 isolation: Allow / disallow routing between IP subnets or directly connected IP networks
	Layer 2 isolation Private VLAN Edge (PVE) with community VLAN: PVE (also known as protected ports) provides Layer 2 isolation between devices in the same VLAN, supports multiple uplinks

	Storm control: Broadcast, multicast, and unknown unicast
	DoS prevention: DoS attack prevention
	Congestion avoidance:
	A TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization
