Layer 2 Switching

Spanning Tree Protocol (STP):

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)

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

Port security: Locks MAC addresses to ports, and limits the number of learned MAC addresses

RADIUS/TACACS+: Supports RADIUS and TACACS authentication. Switch functions as a client

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

ACLs: Support for up to 512 rules

Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, differentiated services code point (DSCP)/IP precedence, TCP/ UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag
