Introduction
This user’s guide is targeted to provide information on installing, configuring
and maintaining the AMG 902x/906x Multi-service Ethernet switches.
AMG 902x/906x Multi-Service Ethernet Switch has all capabilities to support
ruggedized Layer2 Managed Ethernet functionality. In addition to Layer2 &
some Layer3 functionality, these products also support integration of lowspeed I/O, allowing Serial Ports, Alarm Contacts, Audio Devices and
Analogue Video to be directly connected to the switch, without requirement
for any additional hardware.
Historically, this requirement has been dealt with through the use of thirdparty serial port, audio, and Contact-closure I/O servers, resulting in a
disparate, multi-vendor product mix and corresponding issues with product
integration. AMG 902x/906x Multi-Service Ethernet switches eliminate all
these issues with a one-box solution. These switches offer a common web
management interface for configuration of all aspects of the device - Ethernet
as well as serial ports, audio ports and Alarm I/O.
The AMG 902x/906x management features are designed to minimize
administrative management effort, while enhancing and improving network
traffic control.
AMG 902x/906x supports easy management and configuration through
SNMP or WEB GUI.

2.5 Power over Ethernet
Power over Ethernet (PoE) is a provision to power over Ethernet cables. So,
an Ethernet cables carries both data and current together to operate devices
like IP cameras. This is very helpful to install devices in remote places such
as ceilings, where it is hard to find power outlets. Only smaller devices can
be powered using the PoE, as it carries limited power over the Ethernet.
The original IEEE 802.3af-2003 PoE standard provides up to 15.4 W of DC
power (minimum 44V DC and 350 mA) to each device Only 12.95 W is
assured to be available at the powered device as some power is dissipated
in the cable. The updated IEEE 802.3at-2009 PoE standard also known as
PoE+ or PoE plus, provides up to 25.5 W of power.
Here are POE/POE+ specifications of AMG 902x/906x series devices:

VLAN
VLAN (Virtual LAN) module logically segments the shared media LAN to
form virtual workgroups. It fully utilizes the forwarding support available in the
switch hardware. It redefines and optimizes the basic transparent bridging
functionalities such as learning, forwarding, filtering, flooding and so on.
VLAN operates in the following modes. They are:

Transparent bridging – Allows the user to connect two similar network
segments to each other at the data link layer in a manner transparent to
end stations, so the end stations do not participate in the bridging
algorithm.

VLAN aware bridging – Allows the end stations at different LAN
segments to be interconnected and to communicate with each other
using VLANs.
To access VLAN screens, click Layer2 Management > VLAN.
The VLAN related parameters are configured through the pages displayed by

MSTP
MSTP (Multiple Spanning Tree Protocol) is used to configure spanning
tree on per VLAN basis or multiple VLANs per spanning tree. It allows the
user to build several MST over VLAN trunks, and group or associate VLANs
to spanning tree instances, so the topology of one instance is independent of
the other instance. It provides multiple forwarding paths for data traffic and
enables load balancing. It improves the overall network fault tolerance, as
failure in one instance does not affect the other instances.
The MSTP provides an optional capability for:

High availability

Executing multiple instances of the protocol

Provider bridging
To access MSTP screens, click Layer2 Management > MSTP.
The MSTP related parameters are configured through the screens displayed

RSTP
RSTP (Rapid Spanning Tree Protocol) is a portable implementation of the
IEEE 802.1D standard. It provides rapid recovery of connectivity following the
failure of a bridge/bridge port or a LAN. It reduces the time to reconfigure the
active topology of the network when physical topology or topology
configuration parameters changes. It provides increased availability of MAC
service when there is a reconfiguration or failure of components in a bridged
LAN. It can inter-operate with legacy STP bridges without any change in the
configuration.
The RSTP provides an optional capability for:

High availability

Executing multiple instances of the protocol

Provider bridging

LLDP
LLDP (Link Layer Discovery Protocol) is a vendor-neutral Data Link Layer
(neighbour discovery) protocol used by network devices for advertising their
identity, capabilities, and interconnections on an IEEE 802 LAN network. The
protocol is formally referred to by the IEEE as Station and Media Access
Control Connectivity Discovery specified in standards document 802.1AB.
LLDP performs functions similar to several proprietary discovery protocols,
from Cisco, Nortel (SONMP), and Microsoft LLTD (Link Layer Topology
Discovery).
LLDP data is stored in the device as a management information database
(MIB) and can be queried with the Simple Network Management Protocol
(SNMP) as specified in RFC 2922. The topology of an LLDP-enabled
network can be discovered by querying this database.
To access LLDP screens, click Layer2 Management > LLDP.
The LLDP related parameters are configured through the screens displayed

802.1x
802.1x or PNAC provides a means of authenticating devices attached to a
bridge port. It prevents access to a port when the authentication fails. 802.1X
defines (802.1X) port-based authentication as a client-server based access
control and authentication protocol that restricts unauthorized clients from
connecting to a LAN through publicly accessible ports. An authentication
server validates each supplicant (client) connected to an authenticator
(network access switch) port before making available any services offered by
the switch or the LAN.
Until the authentication is provided, 802.1X access control allows only
EAPOL (Extensible Authentication Protocol Over LAN) traffic through the
port. When the authentication is provided, normal traffic is allowed through
the port.
To access PNAC screens, click Layer2 Management > 802.1X.
The 802.1x related parameters are configured through the screens displayed
in the following tabs:


feature in the switch. The default option is Enable. The options are::


Enable – Enables 802.1x based port security feature in the switch. The
switch initiates authentication and sends an EAP-request/identity frame
to the client to request its identity (typically, the switch sends an initial
identity/request frame followed by one or more requests for
authentication information). Upon receipt of the frame, the client
responds with an EAP-response/identity frame.

Disable – Disables 802.1x based port security feature in the switch.
EAPOL frames from the client are dropped. If the client does not
receive an EAP-request/identity frame after three attempts to start
authentication, the client transmits frames as if the port is in the
authorized state

IP Management
IP (Internet Protocol) is an identifier for a computer or device on a TCP/IP
network. Networks using the TCP/IP protocol route messages based on the
IP address of the destination. The format of an IP address is a 32-bit numeric
address written as four numbers separated by periods. Each number can be
zero to 255. Example: 10.5.25.180.
Every computer that communicates over the Internet is assigned an IP
address that uniquely identifies the device and distinguishes it from other
computers on the Internet. Within an isolated network, IP addresses can be
assigned at random as long as each one is unique. However, to connect a
private network to the Internet, the registered IP addresses must be used
(called Internet addresses) to avoid duplicates. The four numbers in an IP
address are used in different ways to identify a particular network and a host
on that network.
Four regional Internet registries -- ARIN, RIPE NCC, LACNIC and APNIC -assign Internet addresses from the following three classes.

Class A - supports 16 million hosts on each of 126 networks

Class B - supports 65,000 hosts on each of 16,000 networks

Class C - supports 254 hosts on each of 2 million networks
The number of unassigned Internet addresses is running out, so a new
classless scheme called CIDR (Classless Inter-Domain Routing) is gradually
replacing the system based on classes A, B, and C and is tied to adoption of
IPv6.

CHAPTER 23 : IP MANAGEMENT
ICMP (Internet Control Message Protocol) is an extension to the IP defined
by RFC 792. ICMP supports packets containing error, control, and
informational messages. For example the ping command uses ICMP to test
an Internet connection.
IP (Internet Protocol) functions at the network layer. IP delivers/forwards
packets to the higher layer and to other hosts/routers. The forwarding table
maintained by IP consists of the Static Routers and the Routes learnt from
other Routing Protocols.

DHCP Server
DHCP (Dynamic Host Configuration Protocol) is used in a wide variety of
devices like ISDN routers, firewalls, etc., for assigning IP addresses to
workstations. Besides obtaining IP address, other configuration parameters
for a workstation can also be configured in a DHCP server. DHCP clients can
retrieve these parameters along with the IP address.
DHCP is based on the client-server architecture. DHCP servers are
configured with an IP address and several other configuration parameters.
DHCP clients, typically workstations obtain this IP address at start-up. The
client obtains the address for a time period termed as the “lease” period.
DHCP clients renew the address by sending a request for the IP address
before the lease expires.
DHCP uses UDP as its transport protocol and a UDP port for communication.
DHCP relay Agents connect servers present on one LAN with the client
present on another.
DHCP server is responsible for dynamically assigning unique IP address and
other configuration parameters such as gateway, to interfaces of a DHCP
client. The IP address is leased to the interface only for a particular time
period as mentioned in the DHCP lease. The interface should renew the
DHCP lease once it expires. The DHCP server contains a pool of IP address
from which one address is assigned to the interface.
To access DHCP screens, click IP Management > DHCP Server.

IGMP Snooping
IGMP (Internet Group Management Protocol) is the protocol, a host uses
to inform a router when it joins (or leaves) an Internet multicast group. IGMP
is only used on a local network; a router must use another multicast routing
protocol to inform other routers of group membership. IGS (IGMP Snooping)
is a feature that allows the switch to listen in on the IGMP conversation
between hosts and routers.
In IGS, a host computer uses IGMP to inform a router that it intends to listen
to a specific multicast address. If another computer snoops such packets, the
other computer can learn the multicast sessions to which the computers on
the local network are listening.
IGS significantly reduces traffic from streaming media and other bandwidthintensive IP multicast applications.


Snooping Mode - Select the IGMP snooping mode. Modes are provided
with redundancy support. The default option is MAC Based. The list
contains:


IP based – IGS protocol operation is based on the IP address and
group address. This mode is chosen if the hardware supports
programming of S, G and *, and G entries

MAC based - Hardware supports only MAC based multicast tables and
the snooping protocol operation is based only on the group address.
Proxy Reporting - Select the Proxy Reporting status in the switch. IGS
network traffic gets reduced. The default option is Enabled. The list
contains:


Enabled - Switch generates reports and forwards them to the router,
based on the available host information.

Disabled – Switch acts as transparent snooping bridge. The switch
forwards all v3 reports and a single v2 report to the router.
Snoop Leave Level - Select the leave processing mechanism to be
implemented at the VLAN level or at port level. When the switch intercepts a
leave group message on a switch port, it normally sends a query to that
multicast group through the same switch port. If no hosts respond to the
query and no multicast routers have been discovered on the switch port,
that port is removed from the multicast group. The default option is Vlan
Based. The list contains:


Vlan Based – Configures the leave mechanism at the VLAN level. In
Vlan based leave processing mode, the fast leave functionality
configurable per VLAN or normal leave configurations are available for
processing leave messages.

Port Based – Configures the leave mechanism at port level. In port
based leave processing mode, the explicit host tracking functionality,
the fast leave functionality or normal leave configurable on an interface
can be used for processing the leave messages.
Snoop report Process Config Level - Select the report processing
mechanism to be used for handling the incoming report messages to be
processed. The default option is Non-RouterPorts. The list contains:


Non-RouterPorts – The incoming report messages are processed only
in the non-router ports. Report message received on the router ports
are not processed.

All-Ports – The incoming report messages are processed in all the
ports inclusive of router ports.
Enhanced Mode - Select the operating status of snooping module. The
default option is Disabled. The list contains:

Enabled – The snooping module operates in enhanced mode. It is a
mode of operation provided to enhance the operation of IGMP snooping
module to duplicate Multicast traffic by learning Multicast group entries
based on the Port and Inner Vlan. This mode of operation is applied
when the downstream devices are less intelligent or not capable of
duplicating Multicast traffic. The module multicasts from an Outer VLAN
(SVLAN) to a set of ports & Inner VLANs (CVLAN). In this mode, an S-
235
AMG SYSTEMS LTD.
tagged multicast data or query packet from one port can result in
multiple copies of the packet on the same egress port, each with a
different C-tag. The Inner VLAN (CVLAN) will typically have a valid
value within the designated range.

Disabled – The snooping module operates in default mode. This mode
of operation is applied when downstream device is capable of
performing duplication of Multicast traffic. In the this mode, the module
multicasts from an Outer VLAN (SVLAN) to a set of ports. The Inner
VLAN (CVLAN) will typically have a value of zero. In this mode, an Stagged multicast data or query packet from one port can result in
multiple packets on separate egress ports, but only one packet on any
one egress port with an S-tag or with no tag.
 Enhanced mode is in enabled state only when the snooping mode
is set as IP Based

Sparse Mode - Select whether the snooping module operates in the
sparse mode or non-sparse mode. This option is to select whether the
unknown multicast traffic should be dropped or flooded when there is no
interested listener. The default option is disabled. The list contains:

Enabled – The IGS module drops the unknown multicast traffic when
there is no listener for the multicast data

Disabled – The IGS module forwards the unknown multicast traffic. The
multicast data gets flooded to the member port of VLAN.
 Sparse mode is in enabled state, only when the snooping mode is
set as IP Based.

Proxy Status - Select the status of the Proxy in the system. In proxy mode
all the reports and queries generated by the switch will be having the switch
IP as the source IP. The list contains:

Enabled – Enables proxy in the system. The switch act as querier for
all downstream interfaces and act as host for all upstream interfaces.

Disabled – Disables proxy in the system.
 Proxy status can be enabled only if Proxy-reporting is disabled

Filter Status - Select the filter status. The default option is Disabled. The
list contains:


Enabled – Enables the IGS filtering feature. The channel registration is
restricted from addition to the database if it is to be filtered. In
transparent snooping, the filtered packet will not be added to the
snooping database but will be forwarded upstream.

Disabled – Disables the IGS filtering feature. All filter related
configurations are allowed but the incoming report will not be subjected
to the filter process. IGS module programs the hardware to remove the
configured rate limit. It flushes all the registrations learnt through a port
if a threshold limit is configured for this interface.
Multicast Vlan - Select the multicast VLAN status. Multicast VLAN feature
can be used for applications where wide-scale deployment of multicast
traffic is necessary. MVLAN registration allows a subscriber on a port to
subscribe and unsubscribe to a particular multicast stream on any of the
multicast VLANs. Multicast VLANs enable efficient multicast data flow in
USER MANUAL AMG 902X/906X
236
CHAPTER 25 : IGMP SNOOPING
separate M-VLANs, while normal data flows through other/different VLANs.
The default option is Disabled. The list contains:


Enabled – Enables the multicast Vlan feature. Router sends a single
copy of the data for the particular MVLAN, instead of forwarding a
separate copy of the multicast data to each VLAN. This saves the
network bandwidth.

Disabled – Disables the multicast Vlan feature. A separate copy of the
multicast data has to be forwarded from the router in the absence of MVLAN.
Report Forwarding - Select whether the report must be forwarded on all
ports or only on router ports. The port which receives the query message
from the router is the Router port. The default option is Router Ports. The
list contains:


Router Ports – Forwards reports only on the router ports

All Ports – Forwards reports on all ports of the VLAN

Non-edge - Forwards the reports on non-edge ports detected by
spanning tree protocol
Query Forwarding - Select whether the query to be forwarded to the
entire member ports of the VLAN or to Non-router Ports. The default option
is Non-Router Ports. The list contains:


All Ports – The query messages are forwarded to all the member ports
of the VLAN.

Non-Router Ports – The query messages are forwarded only to the
non-router ports.
Retry Count - Enter the maximum number of group specific queries sent
on a port on reception of an IGMPv2 leave message. This values ranges
between 1 and 5. The default value is 2.
 When the switch receives leave message on a port, it sends group
specific query to check if there are any other interested receivers for
the group. The Retry Count defines the maximum number of
queries sent by the switch before deleting the port from the group
membership information in the forwarding database. If the
maximum retry count exceeds the RetryCount, then the port will be
deleted from the multicast group membership information in the
forwarding database and received leave message will be forwarded
onto the router ports if there are no interested receivers for the
group.

Query Transmit on TC - Select path redundancy for IGMP Snooping
queries transmission to be enabled or disabled whenever topology changes.
The default option is Disabled. The list contains:

Enabled - Provides path redundancy while preventing undesirable
loops in the network. When enabled allows the path to exchange
information so that only one of them will handle a given message that is
being sent between two computers within the network.

Disabled - Path redundancy is disabled and it leads to flooding of data.

CHAPTER 25 : IGMP SNOOPING

IGMP Snooping Status - Select the status of IGMP snooping on the
specified VLAN. The default option is Disabled. The list contains:


Enabled – IGS is enabled on the specified VLAN. A switch will listen for
IGMP messages from the host connected on those interfaces and build
the software. This ensures that only the ports that require a given
multicast stream actually receive it.

Disabled - IGS is disabled on the specified VLAN.
Operating Version/ Configured Version - Select the Operating
Version of IGS for the specified VLAN. The default option is Version 3. The
list contains:


Version 1 – The port list connected to listeners of Multicast groups is
built based on IGMP membership Reports, Query and Leave messages

Version 2 – The port list connected to listeners of Multicast groups is
built based on IGMP membership Reports, Query and Leave
messages, added support for low leave latency, that is, a reduction in
the time it takes for a multicast router to learn that there are no longer
any member of a particular group present on an attached network.

Version 3 - The port list is based on source filtering information sent by
IGMPv3 hosts in their membership reports to build Source specific
Multicast groups. Support for source filtering, that is, the ability for a
system to report interest in receiving packets only from specific source
addresses, or from other than specific source addresses, sent to a
particular multicast address.
Fast Leave - Select the Fast Leave status of IGS. The default option is
Disabled. The list contains:


Enabled - On receipt of a single leave message, the port information is
immediately removed from the multicast group entry. The switch
immediately removes the port from the forwarding table without sending
a group specific query. The fast leave functionality does not verify if
other interested receivers are still present for the multicast group on the
same port.

Disabled - Normal leave functionality gets enabled. The switch checks
if there are any interested receivers for the group by sending a group
specific query before removing the port from the forwarding table.
Querier Status/ Configured Querier Status - Select whether the
switch is configured as a querier in a VLAN. The default option is Disabled.
The list contains:


Enabled – The switch starts acting as a querier and sends query
messages until it receives best querier information. The switch sends
general queries at regular time intervals. This querier message takes
part in querier election.

Disabled – The switch is configured as non-querier, does not propagate
any general query messages and does not take part in querier election.
Startup Query Count - Enter the number of queries to be sent during
startup of querier election process at the interval of startup query interval.
This value ranges from 2 to 5. The default value is 2.
241
AMG SYSTEMS LTD.

Startup Query Interval(secs) - Enter the interval (in seconds) between
the startup general query messages sent by the switch (querier) during the
startup of querier election process. This value ranges from 15 to 150
seconds. The default value is 32 seconds.
 This value should be less than or equal to one fourth of query
interval value configured for the VLAN.

Querier Interval (secs) - Enter the time period between which the
general queries are sent by IGMP snooping, when the switch is configured
as querier on a VLAN. The switch waits for the configured time period after
sending a general query message. On the expiry of this query interval, the
switch again sends the general query message and restarts the timer. This
value range between 6 and 600 seconds. The default value is 125 seconds.

Other Querier Present Interval(secs) - Enter the time period (in
seconds) that must pass before a multicast router decides that there is no
longer another multicast router which should be the querier. This value
ranges from 120 to 1215 seconds. The default value is 255 seconds.
 This value must be >= ((Robustness Variable * Query Interval) +
(Query Response Interval/2)).
 The Robustness Variable tunes IGMP to expected losses on a link.
IGMPv3 is robust to (Robustness Variable - 1) packet losses.

Router Port List - Enter the static Router port list for VLAN. When the
snooping switch receives a Router advertisement message through a port,
the port is identified as router port and is added in the router port list. The
default option is None.

Blocked Router Port List - Enter the list of ports which are configured
statically as blocked router ports. On a blocked router port the software
discards queries, PIM/DVMRP and Data Messages and prevents the port
from ever becoming a router port. The blocked router port feature does not
involve any hardware programming. Multicast data is dropped on a blocked
router port. Reports are not forwarded to a blocked router port. Reports
coming from blocked router port are not processed. The default option is
None.
 A port cannot be configured as blocked router port, if it is already
configured as static router port

Multicast Vlan Profile - Select the multicast profile identification
configured for a particular VLAN and is used for multicast VLAN
classification. When any untagged report or leave message is received and
the Group & Source address in the received packet matches any rule in this
profile, the received packet is classified to be associated with the VLAN to
which this profile is mapped.

Max Response Code - Enter the maximum response code advertised in
queries which are sent over this VLAN. This value ranges from 0 to 255
tenths of a second. The default value is 100.

Current Version - Displays the working IGMP Version on the given
VLAN. The value can be version 1, version 2 or version 3.


Interface Index - Select the interface index of the port from the list
specified already in the system.

Leave Mode - Select the mechanism to be used for processing leave
messages in the down stream interface. The default option is Normal
Leave. The list contains:

Explicit Tracking – Leave messages are processed using the explicit
tracking mechanism. On receipt of the leave message, the switch uses
its learnt database to determine whether the specified multicast group
has a single receiver or multiple receivers attached to the port. The
243
AMG SYSTEMS LTD.
switch removes the port from the multicast group entry only when no
other receivers are present in the same group.

Fast Leave – Leave messages are processed using the fast leave
mechanism. On receipt of a single leave message the port is
immediately removed from the group entry. The fast leave functionality
does not verify if other interested receivers are still present in the
multicast group on the same port. Hence the feature can be used
effectively only in a point-to-point connection

Normal Leave – A group or group specific query is sent on the interface
when a leave message is received. Once snooping switch sends the
leave message for a multicast group, the snooping switch sends out
query messages and waits for a specified time for the membership
reports from the interested receivers for the given multicast group.
 This field can be configured only when the Snoop Leave Level is
set to Port Based.

Threshold Limit Type - Select the type of limit to be applied for the
interface. The threshold limit will be applied when reports are received from
the downstream interface. The default option is None. The list contains:

None – No limiting is done.

Groups – Limits the IGMP report message based on the group
registration allowed per downstream interface.

Channels – Limit is applied only for IGMPv3 Include and Allow reports
based on the S, G registration that are allowed per downstream
interface.
 The channel limit is applied only for IGMPv3 include and allow
reports. The group limit is applied for all IGMP reports.

Threshold Limit - Enter the maximum number of unique entries (channel
or group) which can be learned simultaneously on the interface. The
software allows the configuration of threshold limit per downstream
interface. Downstream interface refers to a physical port in the default mode
of operation or to a combination of inner VLAN and physical port in the
enhanced mode of operation of the switch. This value ranges from 0 to
4294967295. The default value is 0.
 This field can be configured only when the Threshold Limit Type is
set.

Rate Limit - Enter the rate limit for a down stream interface in the units of
the number of IGMP packets per second. The software calls an NPAPI to
configure this limit into the data path/hardware. The MDL rate limit per port
will eliminate bursts or attacks coming from the specific physical port and
thereby eliminates the case of exhausting the system resources. This value
ranges from 0 to 4294967295. The default value is 4294967295.


TAC
TAC (Transmission and Admission Control) is a utility module that can be
used by multicast protocols for filtering multicast packets and multicast VLAN
classification.
TAC module creates and maintains a set of Group addresses and/or Source
addresses in a profile. These profiles are used for purposes of filtering.
Profiles in this TAC module can also be used for M-VLAN Classification. The
profile table and filter table present in the TAC module are built through
administrator configuration. All configured addresses are stored as address
ranges. When a report is received on a particular interface, the
corresponding profile mapped to this interface is obtained and filter rule table
is scanned to determine if a match exists for the address present in the
incoming report. If the address is present in the profile with permission as
permit, the reports are processed else they are dropped

Contact Closure I/O over IP
The AMG 902x/906x series of Multi Port Ethernet Switches also support
built-in I/O ports. These I/O ports allow serial data ports, alarm contacts,
audio devices and analogue video to be directly connected to the switch.
AMG 902x/906x web management interface has the provision to configure
these I/O features and facilitate connectivity of low speed I/O devices.
Web pages corresponding to I/O ports are available only when device is
configured with serial data / contact closure data ports.
The navigation pane only has I/O menu when serial data / contact closure
ports are present in the device. Number of contact closures in
configuration/status pages correspond to contact closures present in the
device.
To access contact closures I/O screens, click I/O > Contact Closures
There are four examples of use cases of contact closures IO :

Point-to-point

Multiple point-to-point

Point to multipoint

Multipoint-to-point
USER MANUAL AMG 902X/906X

CHAPTER 28 : CONTACT CLOSURE I/O OVER IP
28.1 Contact Closures Applications
The Contact Closures I/O over IP application can be used in several ways,
but the use cases can be divided into three typical applications:

Point-to-Point

Point-to-Multipoint (typically a master-slave application)

Multipoint-to-Point "OR”ing (unicast or broadcast)
Contact Closures Point to Point
When each AMG 902x/906x Contact Closure input is mapped (over IP) to a
Contact Closure output on one AMG 902x/906x switch (Unicast), a single
input controls a single output.
Contact Closures Point-to-multipoint (broadcast / unicast)
When an AMG 902x/906x Contact Closure input is mapped (over IP) to a
Contact Closure output on more than one AMG 902x/906x switch
(Broadcast), a single input controls one output on several AMG 902x/906x
switches.
Multipoint-to-Point "OR”ing
When more than one Contact Closure input is mapped (over IP) to a Contact
Closure output (Multiple Unicast or Multiple Broadcast), the output is
effectively controlled by more than one AMG 902x/906x. In this case the
value of each Contact Closure input is logically “OR”d with all other
corresponding Contact Closure inputs for this output.
This means that ANY AMG 902x/906x Contact Closure input can turn a
corresponding Contact Closure output ON, but ALL incoming Contact
Closure inputs must be OFF before the Contact Closure output is turned
OFF.
28.2 Contact Closure Configuration
Contact Closure inputs & outputs of AMG 902x/906x devices are transferred
through IP protocol. AMG 902x/906x web management interface gives
provision to configure I/O participation and destination IP address(s) of AMG
902x/906x device that are involved in this control.
AMG 902x/906x devices can be configured as point-to-point, point-tomultipoint or multipoint-to-point (with logical “OR”ing function) control through
web management interface.
AMG 902x/906x web management interface has provision to configure input
enable, target IP address and output enable of contact closure.
