SMC8028L2

Managed 28 Port Gigabit
Standalone L2 Ethernet Switch

Product Overview

The SMC8028L2 is a standalone G igabit Et hernet Lay er 2 switch with 24 10/100/1000 ports and 4 combo Gigabit
Ethernet RJ-45/SFP ports. The SMC8028L2 is a fully managed sw itch that supports power saving. It offers advanced
administration through a user-friendly web interface. Sophisticated QoS and VLAN support provide great scalability for
mission-critical applications. Switching ports can be aggregated to create a high bandwidth pipe to the networ k.
Comprehensive netw ork management functions such as STP/RST P/ MSTP protocol for standard bridging, SNM P,
RMON and advanced security are fully supported.

Key Features and Benefits
Performance and Scalability

With 56Gbps switching capacity, the SMC8028L2 delivers
non-blocking and wire-speed switching performance for all
gigabit connections. The supports 24 10/100/ 1000 port s and 4
combo Gigabit Ethernet RJ-45/S F P ports with flexible choices
for copper or fiber uplinks. It allows users to take full
advantage of existing high-performance.

High Availability

With IEEE 802.1w Rapid Spanning Tree Protocol , the
SMC8028L2 provides a loop-free net work and redundant li nks
to the core network with rapid convergence less than 1 second.

IEEE 802.1s Multiple Spanning Tree Protocol allows a
spanning –tree instance per VLAN for Layer 2 load sharing on
redundant links.

IEEE 802.3ad Link Aggregation Control Protocol (LACP)
increases bandwidth by automatically aggregating several
physical links together as a logic al trunk and offers load
balancing and fault toleranc e for uplink connections.

IGMP snooping provides fast client joins and leaves of
multicast streams, prevents flooding of IP multicast traffic, and
limits bandwidth intensive video t raf fic to the subscribers only.

Q-in-Q allows service providers to provide business us er with
secure L2 Virtual Private Network between Headquarter with
branch offices without changing the existing VLAN
configuration.

Comprehensive QoS

The SMC8028L2 offers advanced Quality of Service for
traffic classificati on, marking and scheduling to deliver best-in
class performance for data, voice and video traffic at wire
speed.

8 egress queues per port enable differentiated management of
up to 8 traffic types.

Traffic is prioritized according to IEEE 802.1p, DSCP, IP
precedence and TCP/UDP port number, to provide optimal
performance to real-time applications.

Asymmetric bidirectional rate-limiting per port or per traffic
class preserves network bandwidth and allows maximum
control of network resources.

Enhanced Security

The SMC8028L2 provides enhanced security functions to
protect the network from the edge.

The IEEE 802.1x port-based access control ens ures only
authorized users and devices are al l owed to access the
network.

After users and devices access the network, the network
resources can be restricted per access right.

Access Control Lists (ACLs) restrict users and devices from
accessing sensitive network resources by denying packets
based on L2 /L3/L4headers.

Security Shell (SSH) and Secure Sockets Layer (SSL/HTTPS)
encrypt network management information via Telnet and web,
providing secure network management.

TACACS+/RADIUS authentication enables centralized control
of the switch and restrict s unauthorized users from altering the
configuration of the s witch.

Private VLAN isolates edge ports to ensure user privacy.

Superior Management

The SMC8028L2 support IPV6 management functions in Web/
SNMP / Telnet / TFTP allows it to be used in I P v6 net work for
future investment protection

The SMC8028L2 can be managed through by industry
standard Command Line Interface (CLI) which provides a
common industry look and feel to reduc e training and
operations costs. It also provides easy-of-use web GUI
interface through a standard web browser.

With four groups of RMON, the SMC8028L2 can easily backup
and restore firmware and configurat i on files via TFTP.
