Redundancy

• The 3 mechanisms

15
Hiper Ring

• Connexium Ring

• One Redundancy Manager (RM) per ring
• Configured with RM DIP switch on front panel
• Ring member ports must be forced to 100 Mbs Full
  Duplex
• RM creates an open in the ring by not sending
  traffic on last segment

• RM sends heartbeat packets around the ring
• The Heartbeat returns, the ring is intact
• The Heartbeat does return
• The open is somewhere else in the ring
• Traffic is forwarded on the last segment
• the Heartbeat is received again, the previous
  ring state is restored

Rapid Spanning Tree Protocol

• Principle
• STP and RSTP are a redundant topology design
  which routes Ethernet around broken links
• STP recovery time up to 60 seconds (too long for
  industrial applications)
• RSTP recovery time up to 3 seconds (mechanism
  using by switch connexium)

ROOT BRIDGE
ROOT BRIDGE
The Root Bridge can be configured or
automatically elected
The Root Bridge sends out periodic messages
throughout the network. If messages are not
received by all other switches, a Topology Change
Notification is sent to reconfigure the network.

Traffic optimization

• Port access control
• Flow control
• Prioritzation
• Multicast - Global data

24
Port access control

• Port security

Choice the MAC address or IP address of the
access control
Switch checks the access control either the MAC
address or the IP address ot each port
The swicth reponds in 3 selectable ways to an
unauthorized access no action, message by
sending a trap or disabling a port.

• The Ethernet frame supports 4 priority contained
  in the tag field.

4 priority classes are available - 1 2 low

26
Prioritization

• Connexium port priority
• Frames without tag priority, it is possible to
  assign the priority at the level port of the
  switch.

- 1 Select the port configuration item to open
the port configuration menu
-2 Enter the port priority for each port ( 0 to
7).
Nota The tag priority is over the port
priority.
27
Flow control

• Description
• It is a mechanism which acts as an overload
  protection. During periods of heavy traffic it
  holds off additional traffic.
• Before the overload, the switch sends a request
  to the transmitter to include a small break in
  the sending transmission.

28
Multicast - Global data

• GARP Multicast Registration Protocol (GMRP)
• Describes how multicast information is
  distributed to other switches on layer 2 level.
  Using Multicast messages a single node can send a
  restricted Broadcast to a group of recipients.

Filtering - Broadcast limiter

• Description
• Excessive broadcasts can be disruptive to network
  end device.
• Broadcast Limiter limits the number of broadcasts
  transmitted from a port per second.

- 1 Select the broadcast control mode.
- 2 Enter the broadcast number sent per second (0
no limitation). Yellow indicates that the value
has been changed.
- 3 Click on Set to download the new value and
select the Save menu to save the configuration.
32
Filtering - Virtual LANs

• Principle
• A VLAN is used to isolate traffic on a network
  into workgroups
• A switch can then be configured to separate the
  ports into multiple VLANs

Example Using of VLAN 1 for automation
products and VLAN2 for Office PCs
Traffic or broadcasts from Office PCs will not
disrupt Automation products.
33
Filtering - Virtual LANs

• VLAN configuration

256 VLANs available (VLAN ID range 1 to 4042)
Option of Port configuration - or F not a
member of VLAN M a member of VLAN (packet
sent with a tag) U a member of the VLAN
(packet sent without a tag)

• SNMP Protocol

• Switch connexium supports the Standard Network
  Management Protocol that allows network
  information to be gathered at a central station.
  It provides a rich set of data, current and
  historical, that helps determine the performance
  of the network (packets sent, packets dropped,
  statistics by host, ).

Traffic Capture

• Using a HUB

• Using a Switch

Traffic must be intercepted to be captured. The
switch option port mirroring copies the traffic
to another port for capture.

With Port Mirroring, traffic is copied from the

• The hub allows you to capture all traffic but it
  interrupts the device

Traffic Capture

• Port Mirroring configuration
• Copies all of the traffic from a source port to a
  destination port
• Ports must be in the same VLAN

Synchronizing the system time of the network

• Description
• It allows to synchronize the system time of the
  network. Connexium switches allow you to use
  either the Simple Network Time Protocol (SNTP) or
  the Precision Time Protocol (PTP).
• SNTP Precision of 1 ms. Offers a low-cost
  solution Areas of application of this protocol
  are log entries, time stamping of production
  data, production control.
• PTP Precision in the order of fractions of
  microseconds. An algorithm measures the cable
  delay and device delay to eliminate them.

The local time of switch is synchronized by a
master clock. All clients are synchronized by the
switch and not by the master clock. Imposed delay
by the switch is eliminated.
