Description of Software Features

The switch provides a wide range of advanced performance enhancing features.
Flow control eliminates the loss of packets due to bottlenecks caused by port
saturation. Broadcast storm suppression prevents broadcast traffic storms from
engulfing the network. Port-based, private VLANs and protocol-based VLANs, plus
support for automatic GVRP VLAN registration provide traffic security and efficient
use of network bandwidth. CoS priority queueing ensures the minimum delay for
moving real-time multimedia data across the network. While multicast filtering
provides support for real-time network applications. Some of the management
features are briefly described below.

Configuration Backup and Restore – You can save the current configuration
settings to a file on a TFTP server, and later download this file to restore the switch
configuration settings.

Authentication – This switch authenticates management access via the console
port, Telnet or web browser. User names and passwords can be configured locally or
can be verified via a remote authentication server (i.e., RADIUS or TACACS+).
Port-based authentication is also supported via the IEEE 802.1X protocol. This
protocol uses the Extensible Authentication Protocol over LANs (EAPOL) to request
user credentials from the 802.1X client, and then verifies the client’s right to access
the network via an authentication server.

Other authentication options include HTTPS for secure management access via the
web, SSH for secure management access over a Telnet-equivalent connection, IP
address filtering for SNMP/web/Telnet management access, and MAC address
filtering for port access.

Access Control Lists – ACLs provide packet filtering for IP frames (based on
address, protocol, or TCP/UDP port number) or any frames (based on MAC address
or Ethernet type). ACLs can be used to improve performance by blocking
unnecessary network traffic or to implement security controls by restricting access to
specific network resources or protocols.

Port Configuration – You can manually configure the speed, duplex mode, and
flow control used on specific ports, or use auto-negotiation to detect the connection
settings used by the attached device. Use the full-duplex mode on ports whenever
possible to double the throughput of switch connections. Flow control should also be
enabled to control network traffic during periods of congestion and prevent the loss
of packets when port buffer thresholds are exceeded. The switch supports flow
control based on the IEEE 802.3x standard.

Description of Software Features

Rate Limiting – This feature controls the maximum rate for traffic transmitted or
received on an interface. Rate limiting is configured on interfaces at the edge of a
network to limit traffic into the network. Traffic that falls within the rate limit is
transmitted while packets that exceed the acceptable amount of traffic are dropped.

Port Mirroring – The switch can unobtrusively mirror traffic from any port to a
monitor port. You can then attach a protocol analyzer or RMON probe to this port to
perform traffic analysis and verify connection integrity.

Port Trunking – Ports can be combined into an aggregate connection. Trunks can
be manually set up or dynamically configured using IEEE 802.3ad Link Aggregation
Control Protocol (LACP). The additional ports dramatically increase the throughput
across any connection, and provide redundancy by taking over the load if a port in
the trunk should fail. The switch supports up to 32 trunks.

Broadcast Storm Control – Broadcast suppression prevents broadcast traffic from
overwhelming the network. When enabled on a port, the level of broadcast traffic
passing through the port is restricted. If broadcast traffic rises above a pre-defined
threshold, it will be throttled until the level falls back beneath the threshold.

Static Addresses – A static address can be assigned to a specific interface on this
switch. Static addresses are bound to the assigned interface and will not be moved.
When a static address is seen on another interface, the address will be ignored and
will not be written to the address table. Static addresses can be used to provide
network security by restricting access for a known host to a specific port.

IEEE 802.1D Bridge – The switch supports IEEE 802.1D transparent bridging. The
address table facilitates data switching by learning addresses, and then filtering or
forwarding traffic based on this information. The address table supports up to 8K
addresses.

Store-and-Forward Switching – The switch copies each frame into its memory
before forwarding them to another port. This ensures that all frames are a standard
Ethernet size and have been verified for accuracy with the cyclic redundancy check
(CRC). This prevents bad frames from entering the network and wasting bandwidth.

To avoid dropping frames on congested ports, the SMC8126L2 and SMC8150L2
provide 4 Mbits respectively for frame buffering. This buffer can queue packets
awaiting transmission on congested networks.

Spanning Tree Algorithm – The switch supports these spanning tree protocols:

Spanning Tree Protocol (STP, IEEE 802.1D) – This protocol provides loop detection
and recovery by allowing two or more redundant connections to be created between
a pair of LAN segments. When there are multiple physical paths between segments,
this protocol will choose a single path and disable all others to ensure that only one
route exists between any two stations on the network. This prevents the creation of
network loops. However, if the chosen path should fail for any reason, an alternate
path will be activated to maintain the connection.

Rapid Spanning Tree Protocol (RSTP, IEEE 802.1w) – This protocol reduces the
convergence time for network topology changes to 3 to 5 seconds, compared to 30

1-3

Introduction

1

seconds or more for the older IEEE 802.1D STP standard. It is intended as a
complete replacement for STP, but can still interoperate with switches running the
older standard by automatically reconfiguring ports to STP-compliant mode if they
detect STP protocol messages from attached devices.

Multiple Spanning Tree Protocol (MSTP, IEEE 802.1s) – This protocol is a direct
extension of RSTP. It can provide an independent spanning tree for different VLANs.
It simplifies network management, provides for even faster convergence than RSTP
by limiting the size of each region, and prevents VLAN members from being
segmented from the rest of the group (as sometimes occurs with IEEE 802.1D STP).

Virtual LANs – The switch supports up to 256 VLANs. A Virtual LAN is a collection
of network nodes that share the same collision domain regardless of their physical
location or connection point in the network. The switch supports tagged VLANs
based on the IEEE 802.1Q standard. Members of VLAN groups can be dynamically
learned via GVRP, or ports can be manually assigned to a specific set of VLANs.
This allows the switch to restrict traffic to the VLAN groups to which a user has been
assigned. By segmenting your network into VLANs, you can:

• Eliminate broadcast storms which severely degrade performance in a flat network.

• Simplify network management for node changes/moves by remotely configuring
VLAN membership for any port, rather than having to manually change the network
connection.

• Provide data security by restricting all traffic to the originating VLAN.

• Use private VLANs to restrict traffic to pass only between data ports and the uplink
ports, thereby isolating adjacent ports within the same VLAN, and allowing you to
limit the total number of VLANs that need to be configured.

• Use protocol VLANs to restrict traffic to specified interfaces based on protocol type.

Traffic Prioritization – This switch prioritizes each packet based on the required
level of service, using four priority queues with strict or Weighted Round Robin
Queuing. It uses IEEE 802.1p and 802.1Q tags to prioritize incoming traffic based on
input from the end-station application. These functions can
independent priorities for delay-sensitive data and best-effort data.

This switch also supports several common methods of prioritizing layer 3/4 traffic to
meet application requirements. Traffic can be prioritized based on the DSCP field in
the IP frame. When these services are enabled, the priorities are mapped to a Class
of Service value by the switch, and the traffic then sent to the corresponding output
queue.

Quality of Service – Differentiated Services (DiffServ) provides policy-based
management mechanisms used for prioritizing network resources to meet the
requirements of specific traffic types on a per-hop basis. Each packet is classified
upon entry into the network based on access lists, IP Precedence or DSCP values,
or VLAN lists. Using access lists allows you select traffic based on Layer 2, Layer 3,
or Layer 4 information contained in each packet. Based on network policies, different
kinds of traffic can be marked for different kinds of forwarding.
