Magnum™ Managed Networks Software (MNS), combined with a Magnum 6K Fiber Switch, provides power and efficiency in a managed Ethernet platform.  A full range of industry-standard software functions in the MNS-6K software product enable the versatile Magnum 6K Switches to perform efficiently in a wide range of managed LAN applications, including redundant topologies.

Use of the Internet and high performance software applications continues to grow at a rapid pace. Factory automation, industrial control, video streaming, database queries, communications systems, and file transfers all place a premium on performance, reliability and security. Today’s managed networks need quick response times with trusted services when delivering and receiving data.

Magnum 6K fiber switches can be configured to include a user-selected mix of 10/100 Mb copper, 10 Mb and 100 Mb fiber, and Gigabit (1000 Mb) Ethernet segments. With MNS-6K, network managers are able to manage their traffic and control their network operations for security, fault-tolerance, and performance.

The Magnum 6K-series software, MNS-6K (Rel. 3.0), supports the following:
• SNMP, rich commands including access control
• SNMPv3, for encrypted authentication & access security
• Secure Web Management, graphical user interface (GUI)
• RMON with statistics, history, alarms and events
• GUI with Hubview/Bitview support
• CLI with multi-level Password Security
• VLANs, Port-based, Tag-based, with GVRP
• Spanning Tree Protocol (STP), 802.1d
• Rapid Spanning Tree Protocol (RSTP), 802.1w
• S-Ring™ product and Link-Loss-Learn for redundant rings
• QoS, multi-level 802.1p, ToS and DiffServ
• IGMP Snooping, and multicast pruning
• Telnet, both client and server support
• Remote Access Security
• Port Security, controlled access by MAC address
• Port Mirroring for selective traffic analysis
• Event Log for the 1000 most recent events
• Port Settings Control, copper and fiber ports
• Alarm Relay Contact, for s/w indication of traps & events
• SMTP, for email alerts of traps and events
• SNTP with world-wide time zones
• FTP and TFTP for load/save convenience
• BootP/DHCP for auto-configuration


SNMP (Simple Network Management Protocol) v1, v2, v3
SNMP provides basic network management by using agent software in the
Magnum 6K that collects and saves pre-defined data, and responds to queries
and commands from a network manager station. v1 is implemented per RFC1155,
RFC1157, RFC1212, RFC1213 (MIB II), Bridge MIB RFC1493, and RFC1757 plus
security enhancements. v2 is per RFC 1091-08. v3 provides encrypted authentication
& access security and is per RFC 2271-75. All are supported by TCP/IP
and UDP/IP.
RMON (Remote Monitoring)
A network management protocol more extensive and more powerful than
SNMP. The Magnum 6K Managed Networks Software supports four groups of
RMON (statistics, history, alarms, and events).
STP (Spanning Tree Protocol)
The IEEE 802.1d standard Spanning Tree Protocol provides interoperable support
for redundant paths and connections while preventing loops in the network.
Note: For S-Ring see applicable datasheet.
RSTP (Rapid Spanning Tree Protocol), IEEE 802.1w
Similar to STP but faster in changing interconnection direction. Typically used in
redundant mesh networks. See S-Ring for ring structure solutions.
Link-Loss-Learn feature (patent pending)
The Link-Loss-Learn (LLL) is a unique feature of the Magnum line of managed
switches (patent pending). LLL simplifies and speed up fault recovery for Ethernet
switches used in redundant LAN topologies. When LINK is lost on a port on
which this function is enabled, the address table of the switch is immediately
reset and the address learning process is re-initiated. This allows rapid re-configuration
and fast fault recovery, rather than waiting for switch buffers to age
Alarm Relay Contact
Software operated alarm contact with user-selected alarm conditions.
Port Mirroring
The Magnum 6K can be software configured to mirror (i.e., monitor) any port on
a specific user-designated target port, a handy feature for network troubleshooting.
The user can connect a network probe on a mirrored target port to
analyze the network.
BootP (Bootstrap Protocol)/ DHCP Client (Dynamic Host Config.)
These tools simplify initializing and maintaining a 6K managed switch, maintaining
the user’s software and configuration settings for more convenient access on
designated servers. DHCP as per RFC 1531 and BootP as per RFC951.
Telnet (Terminal over the Network)
A program that enables access to the 6K console functions from a remote user,
coming in over the Ethernet LAN instead of via connecting to the physical
console port itself. Telnet functions are per RFC854 standards. Telnet inbound
and Telnet outbound are both supported.
Password Security
A multi-level CLI log-in is enforced to ensure that only authorized persons can
execute commands on the console device. The Administrator is the highest
level, and there are 4 levels for system operators.
Remote Access Security
Remote access to SNMP via web and Telnet can be controlled by the Switch
Administrator at the IP address level as desired, providing additional remote
access security beyond traditional software capabilities.
Secure Web Management
See applicable datasheet.
Port Security
The MAC addresses that are secure may be either entered by the system
manager, or learned by the Magnum 6K Switch. When Port Security is enabled,
illegal MAC addresses are either dropped or disabled. Applicable events are
noted in the Event log. CLI commands enable the system manager to control
this Port Security function.

SNTP (Simple Network Time Protocol)
Automatically synchronizes the Magnum 6K’s internal clocks with other
devices on the LAN, handling time-zones worldwide as well as time
changes for Daylight Savings. SNTP is per RFC1769.
QoS, 802.1p Prioritization, ToS, DiffServ
Priority traffic is handled with user-established multi-level priorities based
on IEEE 802.1p standards. QoS processes packets through the Switch
based on priority and type of traffic. MNS-6K supports ToS (Layer 3) Type-
Of-Service, which is important with the deployment of Microsoft Windows
2000 ™. MNS-6K supports the DiffServ standard, which marks VoIP and
other real-time traffic using this field.
IGMP Snooping and Multicast Pruning
Field Bus Industrial Ethernet protocols make use of publisher/subscriber
models by multicasting packets onto the network, creating heavy traffic.
IGMP provides the ability to “snoop” and “prune” multicast traffic to
prevent flooding. IGMP, for example, enables video-over-Ethernet multicast
streams from cameras to be directed to multiple viewing sites for
surveillance and incident management.
Port-based VLANs
A user may configure LAN segmentation via groups of ports. All nodes on
the ports in a defined VLAN group can communicate with each other, and
are secure from activity on other 6K switch ports and those associated
Tag-based VLANs, 802.1q
Users may configure 6Ks so that traffic is segmented into VLANs according
to packet tags. Tagging information is used for VLANs and QoS (Quality of
Service) priority identification to be distributed
across multiple managed switches. Static and dynamic (with GVRP) tagged
VLANs are supported.
CLI (Command Line Interface)
CLI, for the Magnum 6K’s console port, offers a rich set of switch
commands, including Tab Key Help feature, through a VT100 character
terminal or equivalent emulation.
Port Settings Control
Individual ports may be configured (or set) to operate according to the
system manager’s selections. Commands for settings include port enable/
disable, speed selection, full-or half-duplex selection, and auto-negotiation
on-off selection, flow control and back pressure enable/disable.
SMTP (Simple Mail Transfer Protocol)
Users may configure the 6K to send an email message upon recognizing
certain traps and events. RFC 821.
Event Log
System events are recorded in a log in memory, enabling the system manager
to track and analyze what has happened within the Magnum 6K system
operations. The predefined MNS-6K system events relate to all of the MNS-
6K software modules and functions, including intruder detection events,
and cover varying system severity levels. The log holds up to 1000 of the
most recent MNS-6K events.
