MAC Address Table Size

Up to 8000 MAC addresses

Frame Sizes

Jumbo Frames: up to 10 KB supported on 10/100 and Gigabit interfaces

Switching Method


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


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

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


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):

802.1X: 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


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


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

Quality of Service

Priority Levels: 4 hardware queues


Strict priority and weighted round-robin (WRR)

Queue assignment based on DSCP and class of service (802.1p/CoS)

Class of Service:

Port based; 802.1p VLAN priority based; IPv4/v6 IP precedence/type of service (ToS)/DSCP based; Differentiated Services (DiffServ); classification and re-marking ACLs, trusted QoS

Rate Limiting:

Ingress policer; egress shaping and rate control; per VLAN, per port, and flow based
