10/100Base-TX Twisted Pair Ports

The 10/100Base-TX twisted pair ports featured on the Converteon™ line cards are described below.
Converteon Media Converter Line Cards Reference Guide
Type of
Connector
The 10/100Base-TX twisted pair ports feature 8-pin RJ-45 connectors. Only four of the pins are used when a port is operating at 10 or 100 Mbps. For the port pinouts, refer to “RJ-45 Twisted Pair Port Pinouts” on page 89.

Speed The twisted pair ports are 10/100Base-TX compliant and are capable of

both 10 megabits per second (Mbps) and 100 Mbps speeds. Since the ports are IEEE 802.3u Auto-Negotiation compliant, you can let the converter set the port’s speed automatically. With Auto-Negotiation, the converter automatically matches the highest possible common speed between the converter port and the end-node. For example, if an end­node is capable of only 10 Mbps, the converter sets the port connected to the end-node to 10 Mbps. Alternatively, you can set the port speed through the management software.
Note
Auto-Negotiation is activated as the default on the twisted pair port on the converter. To deactivate Auto-Negotiation and set the speeds manually, refer to the AT-S70 Management Software User’s Guide.

Duplex Mode The10/100Base-TX twisted pair ports on a Converteon™ line cards can

operate in either half- or full-duplex mode. The twisted pair ports are IEEE
802.3u-compliant and will Auto-Negotiate the duplex mode setting.
If desired, Auto-Negotiation on the converter ports can be disabled so that you can set the duplex mode manually through the converter’s AT-S70 management software.
Maximum
Distance
The maximum operating distance of the 10/100Base-TX twisted pair ports is 100 meters (328 feet).

Type of Cable For 10 Mbps, the port requires Category 3 or better (100 ohm shielded or

unshielded) twisted pair cabling. For 100 or 1000 Mbps, the port requires Category 5 or Enhanced Category 5 (5E) (100 ohm shielded or unshielded) twisted pair cabling.
29
Page 30
Chapter 1: Converteon™ Fast Ethernet and Gigabit Ethernet Line Cards
Auto MDI/
MDI-X
The 10/100Base-TX twisted pair ports are auto-MDI/MDI-X. They automatically configure themselves as either MDI or MDI-X, depending on the configuration of the port on the end node. This feature allows you to use either straight-through or crossover twisted pair cables to connect devices to the ports.
Note
The auto-MDI/MDI-X feature on a port is available only when the port is set to Auto-Negotiation. If you disable Auto-Negotiation and set a port’s speed and duplex mode manually, the port defaults to MDI-X. For instructions on configuring a port, refer to the AT-S70 Management Software User’s Guide.

Port Pinouts For port pinouts when the port is operating at 10 or 100 Mbps in the MDI

configuration, refer to Table 20 on page 89.

Maximum
Distance
The10/100/1000Base-T twisted pair ports have a maximum operating distance of 100 meters (328 feet).

Type of Cable For 10 Mbps, the port requires Category 3 or better 100 ohm shielded or

unshielded twisted pair cabling. For 100 or 1000 Mbps operation, the ports require Category 5 or Enhanced Category 5 (5E) 100 ohm shielded or unshielded twisted pair cabling.
Auto-MDI/
MDI-X
The10/100/1000Base-T twisted pair ports are auto-MDI/MDI-X. They automatically configure themselves as either MDI or MDI-X. This feature allows you to use a straight-through twisted pair cable to connect any type of device to a port.

DIP Switches

Some of the Converteon™ line cards support the following features by configuring their DIP switches:
Link TestMissingLink™ ModeSmart MissingLink ModeOAM Capability
Note
For additional information on how the Link Test (LK), MissingLink (ML), and Smart MissingLink (SML) LEDs function on the Converteon™ line cards, refer to “Link Test, MissingLink™, and Smart MissingLink LED Functionalities” on page 98.

Link Test The link test is a fast and easy way for you to test the connections

between the converter ports and the end-nodes that are connected to the ports. If a network problem occurs, you can perform a link test to determine which port is experiencing a problem, and so be able to focus your troubleshooting efforts on the cable and end-node where the problem resides.
The LK LED for the twisted pair port should be green, indicating that it was able to establish a link with its end-nodes. If the LK LED is off, the port could not establish a link. Refer to “Troubleshooting” on page 83 for suggestions on how to remedy the problem.
For more information on how the LK LED functions, refer to “Link Test, MissingLink™, and Smart MissingLink LED Functionalities” on page 98.
Performing a link test does not interfere with a converter’s ability to pass network traffic.

MissingLink™ The MissingLink™ feature enables the ports on the media converter to

pass the “Link” status of their connections to each other. When the media converter detects a problem on one of the ports, such as the loss of connection to an end-node, the media converter shuts down the connection to the other port, thus notifying the end-node that the connection has been lost.
For more information on how the ML LED functions, refer to “Link Test, MissingLink™, and Smart MissingLink LED Functionalities” on page 98.
For example, if the twisted pair cable to the 10/100Base-TX port on the media converter were to fail, the unit would respond by dropping the link
44
Page 45
Converteon Media Converter Line Cards Reference Guide
on the 100Base-FX fiber optic port. In this way, the media converter notifies the end-node connected to the fiber optic port that the connection on the twisted pair port has been lost. If the failure had started with the fiber optic cabling, the unit would drop the link to the twisted pair port.
The value to this type of network monitoring and fault notification is that some devices can be configured to take a specific action in the event of the loss of connection on a port. In some cases, the unit can be configured to seek a redundant path to a disconnected end-node or send out a trap to a network management station, and so alert the network administrator of the problem.
Smart
MissingLink
The Smart MissingLink feature performs exactly the same function as MissingLink™ with one additional feature. When a link is lost on a port, the LK LED of the port that still has a valid connection to its end-node starts to blink. This allows you to quickly determine which port still has a valid connection (LK LED blinking) and which port has lost its connection (LK LED Off).
For more information on how the SML LED functions, refer to “Link Test, MissingLink™, and Smart MissingLink LED Functionalities” on page 98.
For example, if the network twisted pair cable to the 10/100Base-TX port on the media converter fails, the LK LED on the 100Base-FX fiber optic port blinks, indicating a failed connection on the twisted pair port. If the failure starts with the fiber optic cabling, the LK LED on the twisted pair port blinks.
The value to this type of network monitoring and fault notification is so that you can quickly see which port has failed and troubleshoot your network accordingly.

OAM Overview OAM refers to the tools and utilities to install, monitor, test, and trouble-

shoot a network, helping carriers run their networks more efficiently. Without management features to monitor and troubleshoot the network, it is rather expensive and time consuming to have the problems diagnosed and resolved by having the technicians coming out to the location.
In the enterprise, Ethernet links and networks have been managed via SNMP. Although SNMP provides a very flexible management solution, it is not always efficient and is sometimes inadequate to the task. First, using SNMP assumes that the underlying network is operational because SNMP relies on IP connectivity; however, you need management functionality even more when the underlying network is non-operational. Second, SNMP assumes every station is IP accessible. This requires provisioning IP on every station and instituting an IP overlay network even if the ultimate end-user service is an Ethernet service. This is impractical in a carrier environment.
45
Page 46
Chapter 1: Converteon™ Fast Ethernet and Gigabit Ethernet Line Cards
For these reasons, carriers look for management capabilities at every layer of the network. The Ethernet layer has not traditionally offered inherent management capabilities, so the 802.3ah OAM capabilities act as a first step at providing them. 802.3ah OAM is applicable to the following Ethernet in the First Mile (EFM) technologies:
Ethernet in the First Mile over Copper (EFMC)Ethernet in the First Mile over Fiber (EFMF)Ethernet in the First Mile using Passive Optical Networks (EPON)
Note
Note that these capabilities are not intended to replace SNMP as a management utilities, but are there to enhance it.
Network operators have the freedom to choose and mix the three EFM topologies (copper, fiber, or passive optical networking) based on their business models, network architectures, and subscriber needs. They can configure and upgrade their access networks with multiple EFM topologies and manage them with a common set of tools and OAM procedures.
Additionally, EFM OAM is backwards compatible with any existing full­duplex Ethernet technology, and can be implemented on non-EFM Ethernet links. This compatibility was facilitated by the decision to use standard Ethernet frames as the transport mechanism for management information.
OAM Main Features
Although EFM OAM is compatible with any Ethernet technology and can be used on even small campus networks, it is geared towards reducing expenditures for first mile operators. The OAM work of the IEEE 802.3ah task force addresses three key operational issues when deploying Ethernet across geographically disparate locations: link performance monitoring, fault detection and fault signaling, and loopback testing.
Link Performance Monitoring – Introduces some basic error definitions
for Ethernet so entities can detect failed and degraded connections.
Fault Detection and Fault Signaling – Provides mechanisms for one
entity to signal another that it has detected an error.
Loopback Testing – Is often used to troubleshoot networks, allows one
station to put the other station into a state whereby all inbound traffic is immediately reflected back onto the link.
46
Page 47
Converteon Media Converter Line Cards Reference Guide
OAM Protocol
The operation of OAM on an Ethernet interface does not adversely affect data traffic as OAM is a slow protocol with very limited bandwidth potential, and it is not required for normal link operation. This slow protocol can be implemented in hardware or software, ensuring media independence. By utilizing the slow protocol MAC address, OAM frames are intercepted by the MAC sublayer and cannot propagate across multiple hops in an Ethernet network. This implementation assures that OAM Protocol Data Units (OAMPDUs) only affect the operation of the OAM protocol itself and not user data traffic.
OAMPDU Types
The architecture of the OAM protocol is based on OAMPDU, which are exchanged between two Ethernet ports. OAMPDUs are normal Ethernet frames that use a specific multicast destination address and EtherType.
Most of the OAMPDU types also define a set of standard type-length-value (TLV) encoding of attributes within the type.
Information OAMPDUs
Information OAMPDUs are used for discovery; they are variable-length OAMPDUs.
The different TLVs for Information PDUs are Local Information, Remote Information, and Organizational Specific.
Local and Remote Information is used in the discovery process. The Organizational Specific Information TLV is used for vendor extensions. It is encoded here because the source MAC address is not a simple indication of organization identification as many organizations have multiple OUIs assigned. The 32-bit vendor specific information is not defined and is used to encode the model or version of the platform. The platform identity held is intended to allow simple identification of the hardware device.
Event OAMPDUs
The data field in the Event OAMPDUs contains one or more link event TLVs. This variable-length PDU is used for link monitoring. The link event TLVs may be sent multiple times to increase the likelihood of reception (for example, in the case of high bit-errors). These TLVs may include a time reference when generated.
Loopback Control OAMPDUs
The Loopback Control OAMPDU provides the loopback command.
Variable Request/Response OAMPDUs
The variables accessible through OAM must be in the Ethernet branch of the MIB tree. The process of variable retrieval involves transferring Ethernet counters and statistics via Variable Containers/Descriptors.
47
Page 48
Chapter 1: Converteon™ Fast Ethernet and Gigabit Ethernet Line Cards
Organizational Specific OAMPDUs
Organizations may define events that are of variable-length and are distinguish by the OUI. This is a variable-length TLV.
Unsupported OAMPDUs
Unknown/unsupported OAMPDUs are sent to the OAM Client. This is different from typical Ethernet (802.3x) behavior, which filtered unsupported opcodes.
OAM Discovery
Discovery is the first phase of the IEEE 802.3ah OAM protocol, and relies on what are termed information OAMPDUs. During discovery, information about OAM entities capabilities, configuration, and identity are exchanged.
The discovery process allows a local Data Terminating Entity (DTE) to detect OAM on a remote DTE. Once OAM support is detected, both ends of the link exchange state and configuration information (such as mode, PDU size, loopback support, etc.). If both DTEs are satisfied with the settings, OAM is enabled on the link. However, the loss of a link or a failure to receive OAMPDUs for five seconds may cause the discovery process to restart.
This is one important aspect of the IEEE 802.3ah OAM spec is that an OAM entity may be in either Active or Passive mode.
Active Mode – Active-mode DTEs instigate OAM communications
and can issue queries and commands to a remote station.
Passive Mode – Passive-mode DTEs generally wait for the peer
station to instigate OAM communications and respond to, but do not instigate, commands and queries.
By default, the card should come up in Passive mode for OAM discovery (as per the IEEE 802.3ah). In order to initiate OAM discovery, the card should change from Passive mode to Active mode by the CPM card within a chassis. Therefore, if a line card is in a chassis with no CPM card, it should come up in Passive mode.
The difference between the modes is that an active-mode station can exert more control on its peer than a passive-mode station. For example, an active-mode OAM entity can put a passive-mode OAM entity into loopback mode, but not vice versa.

OAM Loopback
OAM provides a data link layer frame-level loopback mode, which is controlled remotely. Loopback is used to test the performance of a link. Statistics from both the local and remote station can be queried and compared at any time while the remote station is in OAM loopback mode. These queries can take place before, during, or after loopback frames have been sent to the remote station. In addition, an implementation may analyze loopback frames to determine additional information about the health of the link (in example, determine which frames are being dropped due to link errors).
The Converteon™ line cards feature one or two sets of DIP switches, depending on the model. The DIP switches are Diagnostic Mode and Port Configuration DIP switches.
The Diagnostic Mode DIP switches are used to configure the
diagnostic mode positions of the line card.
The Port Configuration DIP switches are used to manually configure
the operating characteristics of the twisted pair port.

A Few Basics about Media Converters

An Ethernet media converter can interconnect network devices over large distances by transferring Ethernet traffic between twisted pair port and fiber optic cabling.
MAC Address
Table
A Converteon™ media converter line card has a MAC address table that can store up to 2K to 32K MAC addresses, depending on the line card model, as listed below:
AT-CM20x Series – 2K MAC AddressesAT-CM212x/1 Series – 2K MAC AddressesAT-CM70S – 2K MAC AddressesAT-CM2K0S – 8K MAC AddressesAT-CV10x Series – NO MAC Address Table (non-bridging card)AT-CV1KSS – NO MAC Address Table (non-bridging card)
The line card uses the table to store the MAC addresses of the network end nodes connected to the ports, along with the port number on which each address was learned.
A line card learns the MAC addresses of the end nodes by examining the source address of each packet received on a port. It adds the address and port on which the packet was received to the MAC table if the address had not already been entered in the table. The result is a table that contains all the MAC addresses of the devices that are connected to the line card’s ports, and the port number where each address was learned.
When the line card receives a packet, it also examines the destination address and, by referring to its MAC address table, determines the port on which the destination end node is connected. It then forwards the packet to the appropriate port and on to the end node. This increases network bandwidth by limiting each packet to the appropriate port when the intended end node is located, freeing the other line card ports for receiving and transmitting data.
If the line card receives a packet with a destination address that is not in the MAC address table, it floods the packet to all the ports on the line card. If the ports have been grouped into virtual LANs, the line card floods the packet only to those ports which belong to the same VLAN as the port on which the packet was received. This prevents packets from being forwarded into inappropriate LAN segments, increasing network security. When the destination an end node responds, the line card adds its MAC address and port number to the table.
If the line card receives a packet with a destination address that is on the same port on which the packet was received, it discards the packet
58
Page 59
Converteon Media Converter Line Cards Reference Guide
without forwarding it on to any port. Because both the source end node and the destination end node for the packet are located on the same port on the line card, there is no reason for the line card to forward the packet.

Duplex Mode Duplex mode refers to the manner in which an end node receives and

transmits data. If an end node can receive or transmit data, but not both simultaneously, the end node is operating in what is referred to as half­duplex mode. If an end node can both receive and transmit data simultaneously, the end node is said to be operating in full-duplex mode. Naturally, an end node capable of operating in full-duplex can handle data much faster than an end node that can only operate in half-duplex mode.
The twisted pair ports on the Converteon™ line cards can operate in either half- or full-duplex mode. The twisted pair ports are IEEE 802.3u­compliant and will Auto-Negotiate the duplex mode setting for you.
By allowing the line card to configure the duplex mode for each port, you will not need to change the setting for a port on the line card should you replace an end node with an end node that has a different duplex mode capability. With Auto-Negotiation, the line card automatically resets the port to a new duplex mode setting.
Store-and-
Forward
If desired, you can disable Auto-Negotiation on the line card ports so that you can set the duplex mode manually through the management software.
In order for a line card port to successfully Auto-Negotiate its duplex mode with an end node, the end node should also be using Auto-Negotiation. Otherwise, a duplex mode mismatch can occur. A line card port, using Auto-Negotiation, defaults to half-duplex if it detects that the end node is not using Auto-Negotiation. This results in a mismatch if the end node is operating at a fixed duplex mode of full-duplex.
Consequently, when you connect an end node with a fixed duplex mode of full-duplex to a line card port, you should use the AT-S70 management software to disable Auto-Negotiation on the port and set the port speed and duplex mode manually.
The bridging media converter line cards, for example the AT-CM20x Series, AT-CM2K0S, and CM212x/1 Series line cards, use store-and­forward as the method for receiving and transmitting frames. When an Ethernet frame is received on a line card port, the line card does not retransmit the frame out the destination port until it has received the entire frame and stored the frame in a port buffer. It then examines the frame to determine if it is a valid frame. Invalid frames, such as fragments or runts, are discarded by the line card. This ensures that only valid frames are transmitted out the line card ports and that damaged frames are not propagated on your network.

If the LK LEDs for the fiber optic ports on two AT-CV102 line cards are flashing when they are operating back-to-back in SML mode, do the following:
Unplug the twisted pair port on either of the two AT-CV102's for at least
20 seconds, then re-insert it.
If you are still experiencing problems after testing and troubleshooting the installation, contact Allied Telesis Technical Support for assistance. Refer to “Contacting Allied Telesis” on page 14 or visit our web site at www.alliedtelesis.com for support information.
