Performance

Switching Capacity in Millions of Packets per Second (mpps) (64-byte packets)

41.67

Switching Capacity in Gigabits per Second (Gbps)

56.0

Management

Web user interface

Built-in web user interface for easy browser-based configuration (HTTP/HTTPS)

SNMP

SNMP versions 1 and 2c with support for traps

SNMP MIBs

RFC1213 MIB-2, RFC2863 interface MIB, RFC2665 Ether-like MIB, RFC1493 bridge MIB, RFC2674 extended bridge MIB (P-bridge, Q-bridge), RFC2819 RMON MIB (groups 1, 2, 3, and 9 only), RFC2737 entity MIB, RFC 2618 RADIUS client MIB

RMON

Embedded RMON software agent supports 4 RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis.

Firmware upgrade

• Web browser upgrade (HTTP)

• Trivial File Transfer Protocol (TFTP) upgrade

Port mirroring

Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe.

Other management

• RFC854 Telnet (menu-driven configuration)

• SSH and Telnet management

• SSL security for web user interface

• Switch audit log

• Dynamic Host Configuration Protocol (DHCP) client

• BOOTP

• Simple Network Time Protocol (SNTP)

• Xmodem upgrade

• Cable diagnostics

• Ping

Security Features

IEEE 802.1X

802.1X - RADIUS authentication. MD5 encryption

Access control

• Filtering: MAC based

• MAC source address (SA)/destination address (DA)

• IP SA/DA

• Ethernet type field

• Protocol

• TCP/UDP port numbers

Availability

Link aggregation

• Link aggregation using IEEE 802.3ad Link Aggregation Control Protocol (LACP)

• Up to 8 ports in up to 8 trunks

Storm control

Broadcast, multicast, and unknown unicast

Spanning Tree

IEEE 802.1d Spanning Tree, IEEE 802.1w Rapid Spanning Tree, Fast Linkover

IGMP snooping

IGMP (version 1 and 2) snooping provides for fast client joins and leaves of multicast streams and limits bandwidth-intensive video traffic to only the requestors.

QoS Quality of Service

Priority levels

4 hardware queues

Scheduling

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.

Congestion avoidance

A TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization.

Class of service (CoS)

• Port based

• 802.1p VLAN priority-based CoS

• IPv4 DSCP-based CoS

• IPv4 ToS/IP precedence-based CoS

Layer 2

Spanning Tree Protocol (STP)

Standard 802.1d Spanning Tree support

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

8 instances are supported

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 4096 VLANs simultaneously 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

Dynamic VLAN assignment via Radius server along with 802.1x client authentication

CPE VLAN

Voice VLAN

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

Auto voice capabilities deliver network-wide zero touch deployment of voice endpoints and call control devices.

Layer 3

IPv4 routing

Wirespeed routing of IPv4 packets

Up to 512 static routes and up to 128 IP interfaces

Classless Inter-Domain Routing (CIDR)

Support for CIDR

Layer 3 Interface

Configuration of layer 3 interface on physical port, LAG, VLAN interface or Loopback interface

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

DHCP Server

Switch functions as an IPv4 DHCP Server serving IP addresses for multiple DHCP pools/scopes

Support for DHCP options
