Key Features and Benefits
The SMC8900 series is a stackable Gigabit Ethernet routing switch with a choice of 24 or 48 Gigabit 10/100/1000BASE-T ports, 4
combo Gigabit Ethernet SFP slots and 2 optional 10 Gigabit Ethernet slots and 2 stacking ports on the rear panel. The SMC8900
series is ideal for service provider edge aggregation, Enterprise wiring closets, data center aggregation and network core deployment.
It provides high performance, resilient stacking, wire speed L2 switching and L3 routing, comprehensive QoS and advanced security
to deliver the scalability and resiliency to increase your company’s productivity while reducing operation cost.
Product Overview
SMC8926EM/50EM
Managed 24/48 port Gigabit Stackable
L3 Ethernet Switch with 4 combo SFP slots
Resilient Stacking up to 8 units
The SMC8900 series currently includes 2 different models
SMC8926EM and SMC8950EM with dual optional10 Gigabit Ethernet
uplinks. The two models provide fully non-blocking performance to fulfill
the most network demands for voice and video streaming. Optional
10GBASE-XFP10 transceivers can support up to 40km for fiber uplinks.
The SMC8900 series provides two stacking ports for hardware stacking
up to 320Gbps throughput. Any combination of SMC8900 series units
can be stacked up to 8 units high or to a maximum of 400 ports. The
stack acts as a single switching unit that is managed by a master switch,
elected from one of the member switches. The master switch
automatically creates and updates all the switching and optional routing
Enhanced Security
The SMC8900 series provides enhanced security features for
connectivity and access control, including ACLs, authentication and
port-level security with IEEE 802.1X. Access Control Lists (ACLs) can
be used to restrict access to sensitive network resources by denying
packets based on L2/L3/L4 headers. SSH and RADIUS authentication
protect data communication and ensure data privacy. IEEE 802.1X
port-based access control ensures dynamic, port-based security and
user authentication for network access
IP source guard prevents a malicious user from spoofing or taking over
another user's IP address by creating a binding table between client's
IP and MAC address, port, and VLAN.
automatically creates and updates all the switching and optional routing
tables. A working stack can add new members or delete old ones
without service interruption.
High Availability
With IEEE 802.1w Rapid Spanning Tree Protocol, the SMC8900 series
provides a loop free network and redundant links to the core network
with rapid convergence less than 2 second. IEEE 802.1s Multiple
Spanning Tree Protocol allows a spanning-tree instance per VLAN, for
Layer 2 load sharing on redundant links.
The SMC8900 series supports IEEE 802.3ad Link Aggregation Control
Protocol (LACP). It increases bandwidth by automatically aggregating
several physical links together as a logical trunk and offers load
balancing and fault tolerance for uplink connections.
Adding Optional Redundant Power Supply ensures that the SMC8900
series delivers the stable and redundant power support for today’s high-
availability, mission-critical environments.
Comprehensive QoS
The SMC8900 series offers advance QoS for marking, classification,
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 across the stack.
Traffic is prioritized according to 802.1p, DSCP, IP precedence and
TCP/UDP port number to provide optimal performance to real-time
applications. Weight Round Robin (WRR) and strict priority ensure
differential prioritization of packet flows and avoid congestion of ingress
and egress queues.
With bidirectional rate-limiting, per port or traffic class, the SMC8900
series preserves network bandwidth and allows full control of network
resources.
IP and MAC address, port, and VLAN.
Simplified Management
For IP multicast traffic, the SMC8900 series enables IGMP snooping to
provide fast client joins and leaves of multicast streams. It prevents
flooding of IP multicast traffic, and limits bandwidth intensive video
traffic to only the subscribers.
The SMC8900 series supports IPv6 management functions in
SNMP/HTTP/Telnet/TFTP/ICMP, SSH, RADIUS/TACACS+
authentication and IPv6 QoS remapping when connecting to the switch
or stack.
The SMC8900 series can be managed through By industry standard
Command Line Interface (CLI) which provides a common industry look
and feel to reduce training and operating costs. It also provides easy-of
use Web GUI interface through a standard web browser.
With four groups of RMON, the SMC8900 series can easily backup and
restore Firmware and configuration files via TFTP.
Advanced IPv6 and IPv4 Routing
The SMC8900 series supports hardware based IPv6 and IPv4 routing
hardware for maximum performance. It provides seamless migration
path from IPv4 to IPv6 for future network upgrades and investment
protection.
Advanced routing protocols such as RIP and OSPF provide dynamic
routing by exchanging routing information with other Layer 3 switches
or routers. Multicast routing is supported under independent multicast
protocol, including PIM-DM*, and PIM-SM*. DVMRP* is also supported
to interconnect two multicast-enabled networks across non-multicast
networks. VRRP prevents your system from failing by dynamically
backing up multiple L3 switches for routing.
