Specifications

Performance

Capacity in Mpps (64-byte packets): 14.88

Switching Capacity in Gbps: 20.0

Layer 2 Switching

Spanning Tree Protocol: Standard 802.1d Spanning Tree support

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

Multiple Spanning Tree instances using 802.1s

Port Grouping: Support for IEEE 802.3ad Link Aggregation Control Protocol

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, also known as protected ports, with multiple uplinks

Guest VLAN

Unauthenticated VLAN

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

Q-in-Q VLAN: VLANs transparently cross a service provider network while isolating traffic among customers

Generic VLAN Registration Protocol/Generic Attribute Registration Protocol: Protocols for automatically propagating and configuring VLANs in a bridged domain

Dynamic Host Configuration Protocol Relay at Layer 2: Relay of DHCP traffic to DHCP server in different VLAN. Works with DHCP Option 82

Internet Group Management Protocol 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: Support for CIDR

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

User Datagram Protocol Relay: Relay of broadcast information across Layer 3 domains for application discovery or relaying of BootP/DHCP packets

Quality of Service

Priority Levels: 4 hardware queues

Scheduling: Strict priority and weighted round-robin

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/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

General Features

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

MAC Table: Up to 8000 MAC addresses
