Preface

Terminology	Refer to this table for terms used in this publication.
Table 1 - Managed Switch Terminology
Term	Description
1783-EMS	All references to 1783-EMS in this manual refer to catalog numbers 1783-EMS04T and 1783-EMS08T.
Auto-MDIX	Automatic Medium-dependent Interface Crossover.
	Allows the switch to detect the required cable type (straight-through or crossover) for copper Ethernet connections and configures the interfaces
	accordingly.
BOOTP	Commonly used with Allen-Bradley Ethernet products, the BOOTP protocol is used by a client machine to locate its IP address and network mask.
DHCP	Dynamic Host Configuration Protocol.
	A network protocol that is used to configure devices, so that they can communicate on an IP network. A client machine uses this protocol to acquire
	configuration information, such as an IP address and default gateway, from a server running the protocol. The client then uses this information to
	configure itself.
DNS	Domain Name Server.
	Translates domain names into IP addresses, for example, www.example.com can translate to 192.168.100.100.
Domain	A group of computers and devices on a network that are controlled as a unit with common rules and procedures.
IGMP	Internet Group Management Protocol.
	A protocol that manages how adapters and other components join and leave multicast groups. IGMP snooping is a feature of IGMP that allows Ethernet
	switches to look (snoop) inside packets to determine which destinations really need to receive the data.
QoS	Quality of service.
	A method of managing network resources through the classification of Ethernet traffic into high and low priority queues.
SMS	Short Message Service.
	A communication service that allows text messaging between mobile phones.
SNMP	Simple Network Management Protocol.
	A protocol that exchanges messages with devices on a network for the purpose of monitoring the devices.SNMP enables a switch to be remotely
	managed through other network management software.
Spanning Tree	Refers to Rapid Spanning Tree Protocol (RSTP) or Spanning Tree Protocol (STP).
	Used with network topologies that provide more than one physical path between two devices, spanning tree protocol manages path redundancies
	while preventing undesirable loops in the network. If a fault should occur on an active port, the switch will begin transmitting out one of the blocked
	ports.
TCP	Transmission Control Protocol.
	TCP enables two hosts to establish a connection and exchange streams of data.
	TCP guarantees delivery of data and also guarantees that packets are delivered in the same order in which they were sent.
UDP	User Datagram Protocol.
	This protocol offers a minimal transport service. UDP is used by applications that do not require the level of service of TCP or use communication
	services (for example, multicast or broadcast delivery) not available from TCP.
	An application program running over UDP must deal directly with end-to-end communication anomalies that a connection-oriented protocol would
	have handled - for example, retransmission for reliable delivery, packetization and reassembly, flow control, and congestion avoidance, when these are
	required.
	This is commonly seen with I/O type devices that send out information at an RPI rate.
VLAN	Virtual local-area network.
	A logical segment of network users and resources grouped by function, team, or application. This segmentation is without regard to the physical
	location of the users and resources.

This chapter covers how to access the switch’s web interface home page. It also includes information about how to set an IP address and security, work with miscellaneous options, and understand status indicators.

Use these steps to access the web interface home page for the switch.

IMPORTANT	Before connecting to the network, set the IP address of the switch as
	described in Set the IP Address.

1.Connect the switch to your computer’s LAN card.

This connection is required before you can access the home page. For information about how to establish this connection, see the Stratix 6000 Ethernet Managed Switch Installation Instructions, publication 1783-IN004.

2.Open your web browser once the connection is established.

3.In the address bar of your web browser, type your switch's IP address. For example, to use the default IP address, type http://192.168.1.1.

4.From the user name and password dialog box, leave the user name empty and type the following case-sensitive password: PASSWORD

If the web browser does not open, verify this information:

•The IP address of the switch. The default IP address is 192.168.1.1.

1.Put the switch on a network with a BOOTP server.

2.Cycle power to the switch.

The 1783-EMS switch attempts to obtain an IP address several times from the server before timing out and defaulting to the factory preset address of 192.168.1.1.

IMPORTANT	The MAC address of the switch is on the home page.
	192.168.1.1 could interfere with another device on the network.

We recommend changing the administrator and read-only password before you place the switch in service.

The administrator password is used for the management interface (HTTP session), Telnet, and the FTP interface (used to upgrade the firmware). The user name is verified for the FTP session only. The user name for the HTTP session is not checked (therefore can be anything). The read-only password is used for read-only access to the management interface (HTTP session).

Use these steps to change your administrative or read-only user name and password.

1.From the navigation pane, expand the Basic Configuration folder and select Set Security to display the Set Security tab.

Network Services Setup

SNMP

This chapter covers information related to network services setup using the switch’s web interface, including how to configure these protocols:

•Simple Network Management Protocol (SNMP)

•Internet Group Management Protocol (IGMP)

•Dynamic Host Configuration Protocol (DHCP)

For information about how to access the web interface for the switch, refer to Chapter 1.

Simple Network Management Protocol (SNMP) specifies the diagnostic data that a host computer must maintain for network management software. Hosts typically keep statistics on the status of their network interfaces, incoming and outgoing traffic, dropped datagrams, and error messages generated. Network management protocols let network management software access these statistics.

SNMP is based on three concepts:

•SNMP managers, also known as client software or SNMP browsers

•SNMP agents, also known as network devices or SNMP servers

•Management Information Base (MIB)

The SNMP manager runs SNMP management software. Network devices to be managed, such as bridges, routers, servers, and workstations, have an agent software module. The agent provides access to a local MIB of objects that reflects the resources and activity of the device. The agent also responds to manager commands to retrieve values from the MIB. The agent and the MIB are on the switch. To configure SNMP on the switch, you define the relationship between the manager and the agent.

The Stratix 6000 switch supports SNMP versions 1 and 2.

•SNMP versions 1 and 2 are generally used for network monitoring without network control.

•The supported versions use a community-based form of security. SNMP managers can access the agent MIB through passwords referred to as community names.

•The Stratix 6000 switch automatically recognizes the SNMP version from an incoming request, but you must manually set the version for SNMP trap destinations, as described on page 24.

Supported MIBs

The Stratix 6000 switch supports the MIBs listed below.

•MIB-II—The published definition of MIB-II has been modified for the Stratix 6000 switch, as described in MIB-II Modifications below. For a detailed definition of MIB-II, refer to RFC 1213 at http://www.ietf.org/ rfc/rfc1213.txt.

•ETHERLIKE-MIB—For a detailed definition, refer to RFC 1643 at http://tools.ietf.org/html/rfc1643.

•RMON-MIB—The Stratix 6000 supports only the Ethernet Statistics Group in the RMON-MIB. For a detailed definition, refer to RFC 2819 at http://tools.ietf.org/html/rfc2819.

SNMP Configuration

Enable SNMP if you want to run SNMP on your network. SNMP is disabled by default.

Before configuring SNMP settings, understand these concepts:

•Community names—Community names are passwords to the switch Management Information Base (MIB) that allow a remote manager readonly or read-write access to the switch. The Stratix 6000 switch supports one read-only community name and one read-write community name. You can change the default names.

•SNMP traps—SNMP traps are unsoliticited messages sent to a remote manager from an agent. Traps are an efficient way to inform managers that are connected to a large number of devices with many objects. By providing unsolicited messaging, traps can reduce SNMP polling by a manager. The Stratix 6000 switch supports two destination traps that can be enabled or disabled. By default, both traps are disabled.

Use these steps to configure SNMP.

1.From the navigation pane, expand the Network Services Setup folder and select SNMP Configuration.

Rockwell Automation Publication 1783-UM001D-EN-P - January 2013

23

Chapter 2 Network Services Setup

2.From the SNMP Enabled pull-down menu, choose Enabled to use SNMP.

3.Change the deault case-sensitive community names if desired.

•The read-only community enables the switch to validate Get (readonly) requests from a network management station. If you set the SNMP read community, users can access MIB objects, but cannot change them.

•The read-write community enables the switch to validate Set (readwrite) requests from a network management station.

4.In the System Info area, provide optional information about the switch for informational purposes only.

a. In the Location field, type the physical location of the switch, such as the building where the switch is locatd.

b. In the Contact field, type the switch name or network administrator.

5.Identify up to two trap destinations by completing the fields below.

Trap Destination Field	Description
Enabled	Check to enable trap messages to be sent.
IP Address	Type the IP address of the SNMP trap recipient.
Port	Type the UDP port number to which traps will be sent.
	The default port number is 162.
Community	Type the read-only or read-write SNMP community name to be used in
	traps sent to the destination.
	Community names are case-sensitive.
SNMP Version	Choose the SNMP version to use.

6.Click Apply Changes.

The changes will take effect immediately without requiring you to cycle power to the switch.

IGMP

Internet Group Management Protocol (IGMP) snooping sorts multicasting devices into groups. This limits the multicast packets received by hosts that do not need the information and makes the network more efficient and deterministic.

Option	Description
Broadcast	Without IGMP snooping, an I/O module acts like a broadcasting device and all
	devices on the subnet are flooded with I/O traffic.

Multicast	IGMP snooping filters the I/O traffic from devices that are not in the intended
	multicast group.

Unicast	A message instruction from one Logix controller to another is an example of
	unicast; it contains one source and one destination address.

By default, IGMP is disabled. Enable IGMP snooping when I/O is running on your network. IGMP helps to isolate this UDP traffic to ports that need to receive it. When it is not used, other devices may be slowed down by the continuous flow of UDP packets.

IGMP Product Support

Rockwell Automation products support IGMP, version 2.

When using the Logix Designer application to configure your switch, consider the following:

•Settings on the IGMP page in the Add-on Profile overwrite settings made on the web management interface.

•If you are scanning the 1783-EMS switch with the Logix Designer application, use the IGMP page in the Add-on Profile to configure IGMP to avoid confusion. See Appendix E for more information.

The switch manages a report of IGMP information, including multicast groups, querier information, and IGMP states per virtual local-area network (VLAN). The report is available through the web interface. For more information about this report, refer to IGMP Report on page 45.

Chapter 2 Network Services Setup

IGMP Querier

The IGMP querier function can be enabled to query your network for group information at a specified time interval. The configuration options available for IGMP querier depend on whether VLANs are enabled on your network.

•If you plan to use VLANs on your network, the IGMP querier function can be enabled for only one VLAN per switch. The IP address of the querier may be different on each VLAN.

You can choose to assign the querier to the management VLAN or a custom VLAN. The querier is assigned to the management VLAN by default.

–If the querier is assigned to the management VLAN, the querier IP address is the IP address defined on the Network Configuration tab, as described in Set the IP Address on page 15.

–If you want to assign the querier to a custom VLAN, you must first set up the custom VLAN on the VLAN Configuration tab, as described in VLAN Configuration on page 57. Assigning the querier to a custom VLAN requires you to know which IP address you want to assign to the querier.

•If you do not plan to use VLANs on your network, you can enable or disable a single querier instance on the network. The querier function is enabled by default. If more than one querier instance is detected on the network, only the querier with the lowest IP address is active. All other queriers are silent.

4.If VLAN is not enabled on the switch, choose to enable or disable the IGMP querier function from the Querier Mode pull-down menu.

or

If VLAN is enabled on the switch, choose one of these options from the Querier Mode pull-down menu:

•Disabled—The IGMP querier function is disabled on all VLANs.

•Enabled on Management VLAN—The IGMP querier function is enabled and assigned to the management VLAN only. This is the default setting. For more information about setting up the management VLAN, refer to VLAN Configuration on page 57.

•Enabled on Custom VLAN—The IGMP querier function is enabled and assigned to a custom VLAN. If you choose this option, you must also specify the querier VLAN and IP address as described in step 6.

5.In the Querier Period field, specify a time interval in minutes, 1…60, to determine how often your network is queried for group information.

The default querier period is 2 minutes.

IMPORTANT Specify the same number of minutes on all switches in the network. The querier period must be specified even if the querier function is disabled.

6.If you chose the Enabled on Custom VLAN querier mode, complete the fields described below.

•Querier VLAN—Choose the custom VLAN to which to assign the querier.

•Querier IP Address—Type the IP address of the querier running on the custom VLAN.

Additional fields appear when you choose the Enabled on Custom VLAN querier mode.

7.In the Router Ports Configuration area, choose the methods to use for detecting when a multicast router is connected to a switch port.

When a multicast router, including IGMP querier, is connected to a switch port, all multicast packets and IGMP reports are forwarded on that port. This behavior is important for the proper functioning of IGMP snooping.

You can enable one or both of the following options:

•Autodetect—Accept the default setting of Enabled if you want the switch to automatically determine whether an end station or multicast router is connected to its ports. To determine which type of device is connected to a port, the switch uses Cisco Discovery Protocol (CDP) or Multicast Router Discovery (MRD).

•Manual—Enable this setting if you need to connect a switch from a different vendor that does not support CDP or MRD protocols. When

you enable the Manual setting, a series of checkboxes appears, so you can specify which ports will be connected to a router that does not support CDP or MRD protocols.

8.From the Multicast Packets Forwarding pull-down menu, choose where to forward multicast packets.

•To Listeners Only—The switch forwards multicast packets to ports in the Listening state only.

•To Listeners and Uplink Port—The switch forwards multicast packets to ports in the Listening state and the uplink port. This is the default setting.

TIP	This setting is useful if you need to route multicast packets between
	two networks.

•To Listeners and All Snooper Ports (Standard)—The switch forwards multicast packets to ports in the Listening state and to all multicast routers, or snoopers. Use this setting if you want multicast traffic to be filtered only on ports where end stations are connected and not between switches.

9.From the Uplink Port pull-down menu, choose Autodetect (Querier) if you want the Stratix 6000 switch to automatically determine the uplink port. Otherwise, set the uplink port manually by choosing a specific port.

10.Click Apply Changes.

The changes will take effect immediately without requiring you to cycle power to the switch.
