I - About the iMcV-Giga-FiberLinX-II Overview The iMcV-Giga-FiberLinX-II™ allows network operators to deploy managed Ethernet services, with a full range of remote management, traffic monitoring, and alarm reporting features. This unit converts 1000 Mbps fiber to 10/100/1000 Mbps copper. In addition, a range of fiber connectors (SC, ST, or SFP) and a variety of wavelengths, supporting higher density CWDM and single-strand fiber operation are available.
The iMcV-Giga-FiberLinX-II module is a double-slot, chassis-mounted module.
iView2 Management Software iView² is the IMC Networks management software designed specifically for the IMC Networks “iMcV” family of modules. It features a graphical user interface (GUI) and gives network managers the ability to monitor and control the manageable IMC Networks products. iView2 is available in several versions and can also function as a snap-in module for HP OpenViewTM Network Node Manager.
About Dynamic Host Control Protocol (DHCP) The iMcV-Giga-FiberLinX-II module includes a Dynamic Host Control Protocol (DHCP) client. By default, the DHCP client is disabled. When a DHCP server is enabled on the network, the DHCP client will initiate a dialogue with the server during the boot up sequence. The server will then issue an IP address, Default Gateway address and Subnet mask to the module. After the new IP address is received, the iMcV-Giga-FiberLinX-II will reboot with the new IP address.
II - LED Operation The following are iMcV-Giga-FiberLinX-II diagnostic LEDs. In this example, the functions for a 1x9 fiber port version (SC fiber) are shown below. NOTE In the SFP/SFP version the LNK/ACT and FDX/COL LEDs replace EXT 1000 and DATA 1000 for the top SFP, which does not have built-in LEDs like the RJ-45 DATA port. In addition, the copper SFP LNK/ACT LED glows green (does not flicker). Port LEDs FDX/COL: • Glows yellow when port is operating in Full-Duplex.
III - Hardware Configuration Before installing the module in a chassis, there are two features that must be selected using the DIP switches. These selections are: • • Enable or disable management on each port (DIP switches 1, 2, and 3) Configure the module as a standalone, a host, or a remote (DIP switches 7 and 8) DIP Switch Settings Before installing the iMcV-Giga-FiberLinX-II, use the DIP switches to set the hardware-configurable features.
queried by SNMP. As a Remote unit, the iMcV-Giga-FiberLinX-II will respond to requests for management information from an attached Host unit. The iMcV-Giga-FiberLinX-II default configuration is as a Standalone unit (DIP switches 7 and 8 = OFF). Management Although the iMcV-Giga-FiberLinX-II provides a twisted pair port solely for management (EXT MGMT), you can configure iMcV-Giga-FiberLinX-II to accept IPbased management traffic from any of its three ports.
IV - Installation Instructions Each iMcV-Giga-FiberLinX-II module requires two slots in an iMediaChassis or MediaChassis. To install the module in a chassis, remove the blank faceplates covering the slots where you want to install the module. Then slide the module into the chassis card guides until the module is seated securely in the connector. Secure the module to the chassis by tightening the captive screw. The iMcV-Giga-FiberLinX-II module includes on-board SNMP logic.
Assigning IP Information When the iMcV-Giga-FiberLinX-II is installed in an iMediaChassis, you can use UMA to manage your iMcV-Giga-FiberLinX-II without an IP address (refer to the iView² online help for more information on UMA). When the iMcV-Giga-FiberLinX-II is not installed in an iMediaChassis, SNMP-management is not accessible until the iMcVGiga-FiberLinX-II IP information (e.g., IP address, subnet mask, etc.) is configured (using iConfig, a serial port DB-9 connection, or DHCP).
Advertising, rather than Force Mode, when connecting to devices that only use autonegotiation. Refer to Port Configuration on page 19 for more information. Bandwidth Control Link Speed (Mbps) 10 100 1000 Speed Increments (Kbps) 4.88 48.8 244 The iMcV-Giga-FiberLinX-II includes bidirectional bandwidth control in increments of 244 Kbps per second at gigabit speed (configurable via iView2).
FiberAlert FiberAlert minimizes the problems associated with the loss of one strand of fiber. Normally when a single strand of fiber is lost, the transmitting side of the connection is unaware that there is a fault. FiberAlert returns faults back on the fiber they came in on.
Loopback Testing on Remote or Standalone The following functions are available during loopback testing. During loopback testing, management traffic entering the uplink port is still capable of managing the device. Address Swap A Layer 2 Ethernet switch will discard all received packets with the same MAC address as sent packets. To avoid this issue the Loopback feature can swap the source and destination MAC addresses on the looped data.
VI - Using Telnet You must assign the iMcV-Giga-FiberLinX-II an IP address before using a Telnet session (this is not necessary when you are using UMA). Refer to the Assigning IP Information section for more information. All of the configurations that you can perform from the serial port can also be performed using a Telnet session. You can only use one Telnet session at a time. The three levels for Telnet account access are: • • • User–view status, change own password, and reboot.
Basic Device Configuration After running through an initial self test, the prompt: “Press for Device Configuration” displays. Press Enter to open the Main Configuration screen: Saved Values. IP Address - 10.10.10.10 Subnet Mask - 255.0.0.0 DHCP is not active Default Gateway - 000.000.000.000 Server IP Addr - 000.000.000.000 New PROM File - filename Current Values. IP Address - 10.10.10.10 Subnet Mask - 255.0.0.
NOTE After making any modifications to the Saved Values, reboot the unit for your changes to take effect. To reboot, type the word reboot at the prompt on the Main Configuration screen. (I) - Assigning IP Information Press I to modify the Saved Parameter Values (i.e., assign the IP address and subnet mask). You will be prompted to enter the IP address and subnet mask for the connected device. Press Enter after each entry.
(T) - Assigning SNMP Trap Destinations Traps are sent by the manageable device to a management PC when a certain event takes place. To enter a trap destination, press T. At the prompt, “Enter a New IP Address,” type the IP address of the destination device, and then press Enter. Next, type the name of the community string (that the destination device has been configured to accept) and press Enter. Select whether the trap is for SNMP version 1 or 2c and press Enter.
(U) - Deleting All SNMP Community Strings To delete all community strings and start over, press U. You will then be prompted, “Are you sure you want to delete all community strings?” Press Y to proceed, N to abort. Press Enter to finish. This function will delete all community strings. If you want to be able to selectively delete community strings, use iConfig to configure your device. (E) - Ending Your Session Ensure you press E to end the session before disconnecting the serial cable.

7. The download progress displays and ends with a successful download message or with an error message. 8. Press Q or F4 to return to the Device-Specific Options screen. When the iMcV-Giga-FiberLinX-II is installed in a managed chassis, you have the option of using UMA to update the firmware (refer to the iView2 online help for more information on using UMA with iConfig, iMediaChassis and iMcV-Giga-FiberLinX-II).
Advertise Ctrl–Selective advertising is used in combination with autonegotiation to advertise your selected speed and duplex mode for the DATA and EXT MGMT ports. This allows you to advertise all speeds and duplex modes. You must enable autonegotiation for selective advertising to work. NOTE If a specific speed and/or duplex mode are desired, IMC Networks recommends using selective advertising, instead of force mode (FO), when connecting to devices that can only autonegotiate.
NOTE Default mode is the factory default and is provided as a starting point from which to configure the iMcV-Giga-FiberLinX-II modules. This mode does not provide full management isolation and is not recommended for normal use. This section describes the Telnet/serial port screens and fields available for configuring the iMcV-Giga-FiberLinX-II modes. The iMcV-Giga-FiberLinX-II modes are configured using the config command from the Device-Specific Options screen.
Transparent Mode Setup This parameter allows you to use all untagged data as the management domain by entering N, or allows you to define a VLAN ID tag for the management domain by entering Y. When you enter Y, this field expands to display the Management Tag field and the Management Priority field.
TRANSPARENT MODE SETUP Is a VLAN tag required on Management packets? [ Y ] The Management Tag is [7 ] Management Priority is [0 ] Are VLAN Tags required on the EXT Port? [ N] Do you want to enter the Extra Tag mode? Enter Y for Extra Tagging. Enter N if you do not want Extra Tags [ N ] Type S or F3 to save the new information Type Q of F4 to quit and cancel changes Reboot is required for any change to take affect.
No VLANs are defined allowing only untagged packets to pass through the unit. Port VLAN on OPTICS (or UPLINK) port This parameter allows you to restrict traffic to a single VLAN ID tag for the OPTICS (or UPLINK) port by entering Y in the Tags column of the Optics row. In the VLAN IDs Saved column of the Data row, enter the VLAN ID tag to be used (in this example, 13). This VLAN ID will be added to all untagged traffic entering the DATA port and removed from all traffic leaving the DATA port.
must enter Y in the Tags column for both the Optics row and Data row. Enter up to 32 VLAN IDs in the Data VLANs fields, plus one for SNMP. Saved VLAN Values . Current VLAN Values .
Configuration screen, press the space bar, type unit, and press Enter to open the Unit Control Settings screen. In this screen you can view the unit FlowControl, FiberAlert/LinkLoss, Loopback, Maximum Frame Size, and 802.1p Base Priority (logging-in as a User in a Telnet session allows you to view these settings but prevents you from changing the settings).
Unit Max FrameSz–enter the maximum frame size on the unit by using the number keys. The valid values are 1518 to 12196. 802.1p Base Pri–set the threshold between low and high priority on the unit. For example, when the Base VLAN Priority is set to 4, priority settings of 0 through 3 are low priority and settings of 4 through 7 are high priority. When the Base VLAN Priority is set to 3, priority settings of 0 through 2 are low priority and priority settings of 3 through 7 are high priority.
NOTE It is not recommended to set both the RX and TX Bandwidth limits at the same time. Unit RateControl Enable/Disable–enable or disable the bandwidth limiting feature on this unit.
Will you define VLAN IDs? When you want to use VLAN traffic with specific tags on any/all of the DATA ports, you will need to disable Transparency and define VLAN IDs (refer to VLAN Configuration section). When you want to use both VLAN tagged, untagged, or double-tagged traffic, enable Transparency. When you want to use only untagged traffic, set the unit to Default mode.
Transparent with Untagged Management Transparent with Untagged Management mode passes tagged traffic between the DATA port and the OPTICS (or UPLINK) port and allows untagged traffic to be considered management domain traffic (untagged). To configure this mode, do the following: 1. Set the management DIP switch ON for the ports using management (in this example it is the OPTICS (or UPLINK) port: 3 = ON). To enable External Management (EXT MGMT), set DIP Switch 1 to ON.
NOTE The flow of management domain traffic is defined by the DIP switches. For example, if the management DIP switches are on the OPTICS and DATA ports, management domain traffic is allowed to flow through those ports.
Transparent with Tagged Management Transparent with Tagged Management mode passes both tagged and untagged traffic between the DATA port and the OPTICS (or UPLINK) port. By using a VLAN Tag you can isolate and route the management path in the module. This method can be used with or without continuing the management path down the EXT MGMT port. To configure this mode, do the following: 1.
d. Enter the management tag (VLAN ID) and the priority (optional). Is a VLAN tag required on Management packets? [ Y ] The Management Tag is [7 ] Management Priority is [0 ] e. Ensure the Are VLAN Tags required on the EXT Port? field is set to N. Are VLAN Tags required on the EXT Port? [ N ] f. Press S or F3 to save the settings. This will set all traffic with VLAN ID 7 as management. g. Type reboot.
Transparent with Extra Tagging (Q-in-Q) Transparent with Extra Tagging mode can add an extra tag to data received on the DATA port. By using Extra Tagging in a Host/Remote iMcV-Giga-FiberLinX-II pair, all data received on the Remote iMcV-Giga-FiberLinX-II DATA port can be extra-tagged and sent out of the Host iMcV-Giga-FiberLinX-II DATA port with a unique tag for identification in the Host cloud.
Enter the extra tag VLAN ID (for example, 8) and the Priority (optional). These values must be identical on both iMcV-Giga-FiberLinX-II modules. The Data Tag is [8 ] Data Priority is [0 ] Are Extra Tags left on the Data Port? [ N ] 4. On the Host iMcV-Giga-FiberLinX-II module, enter Y in the Are Extra Tags left on the Data Port? field to accept only the Extra Tag VLAN ID on the DATA port.
Port VLAN The Port VLAN mode allows you to configure the iMcV-Giga-FiberLinX-II to accept only data tagged with one specific VLAN ID. This mode can be configured for either the OPTICS (or UPLINK) port or the DATA port. VLAN on DATA Port–Configuration To configure this mode, perform the following: 1. In the Main Configuration screen, press the space bar and type config.
In the SNMP field, type Y. VLAN IDs Current Saved Priorities Current Saved Tags Ports Data VLANs are used only Optics [0 ] [13 ] [0 ] [0 ] [ N ] if Tags are enabled on both Data [0 ] [0 ] [0 ] [0 ] [ Y ] the Optics and Data Ports. Management VLAN.........................EXT Mgmt Tag SNMP....[0 ] [20 ] [0 ] [0 ] [ Y ] 4. Press S or F3 to save the settings. 5. Type reboot. Now the iMcV-Giga-FiberLinX-II is configured to pass only VLAN ID 13 from the DATA port to the OPTICS (or UPLINK) port.
VLAN on OPTIC Port–Configuration To configure this mode, do the following: 1. In the Main Configuration screen, press the space bar and type config. The Configuration screen displays: Transparent Mode – with either (not both) Data and Optics Mgmt dipswitches set to on, all traffic passes between Optics and Data port EXCEPT what has been defined as the Management Domain. The Management Domain can either be defined as untagged traffic or traffic with a specified VLAN ID.
5. Press S or F3 to save the settings. 6. Type reboot. The iMcV-Giga-FiberLinX-II is now configured to pass only VLAN ID 13 from the OPTICS (or UPLINK) port to the DATA port. Untagged packets arriving at the DATA port (Tags = N) receive a tag (VLAN ID = 13) before being sent out of the OPTICS (or UPLINK) port. The VLAN ID number used for a port must be different than the number used for the Management VLAN ID.
Port VLAN Filter The VLAN filter mode allows you to isolate a segment of the network to only accept data using some or all of the 32 available VLAN IDs. To configure this mode, do the following: 1. In the Main Configuration screen, press the space bar and type config. The Configuration screen displays: Transparent Mode – with either (not both) Data and Optics Mgmt dipswitches set to on, all traffic passes between Optics and Data port EXCEPT what has been defined as the Management Domain.
Enter up to 32 VLAN IDs in the Data VLANs rows. VLAN IDs can range from 1 to 4094. Only the VLANs in this list will pass through the unit. Data VLAN VLAN VLAN VLAN VLAN VLAN VLAN VLAN VLAN VLAN VLAN VLANs Data> 1 [0 ] [101 ] VLAN 12 2 [0 ] [102 ] VLAN 13 3 [0 ] [103 ] VLAN 14 4 [0 ] [104 ] VLAN 15 5 [0 ] [105 ] VLAN 16 6 [0 ] [106 ] VLAN 17 7 [0 ] [107 ] VLAN 18 8 [0 ] [108 ] VLAN 19 9 [0 ] [109 ] VLAN 20 10 [0 ] [110 ] VLAN 21 11 [0 ] [111 ] VLAN 22 5. Press S or F3 to save the settings.
Now the iMcV-Giga-FiberLinX-II is configured to pass only packets with tags containing the VLAN IDs defined in the Data VLANs table. VLAN ID numbers defined in this table must not be the same as the number used for the Management VLAN ID.
IX - Troubleshooting • If two iMcV-Giga-FiberLinX-II Host/Remote units are not communicating properly, make sure one is a Host (DIP switch #8) and the other is a Remote (DIP switch #7). If the second unit is not configured as a Remote, it will be recognized as a Standalone unit and the Host and Remote units will not communicate with each other properly. Setting the OPTICS (or UPLINK) port management DIP switch #3 to the ON position on both modules will allow you to perform a simple ping test.
• To restore the unit to factory default settings, use the cleandb function via the serial port (refer to the Device-Specific Options from the Command Line section for more information). This is especially helpful if you feel you have configured the module improperly. If restarting to factory defaults is necessary, IMC Networks recommends using this function on both units in Host/Remote applications, and then reconfiguring all settings.
Troubleshooting LinkLoss/FiberAlert/Link Fault Pass-Through The following diagrams show you how the different troubleshooting configurations for the iMcV-Giga-FiberLinX-II. The iMcV-Giga-FiberLinX-II also sends out link pulses from its copper and fiber transmitters, but normally has no way of knowing whether the cable to the other device is intact and the link pulses are reaching the other end.
FX LinkLoss Normally when a fault occurs on the fiber segment of an iMcV-Giga-FiberLinX-II conversion, only the fiber port LEDs on the modules indicates a fault. None of the devices connected to the RJ-45 ports are aware of the fault. When FX LinkLoss is enabled on the iMcV-Giga-FiberLinX-II module, the fiber fault is forwarded to that module’s RJ-45 connection. This turns off the link on the RJ-45 port which can then be detected by the connected device.
TX LinkLoss When a fault occurs on a twisted pair segment joining a device to an iMcV-Giga-FiberLinX-II module, the link fault is not detected by the device connected to the iMcV-Giga-FiberLinX-II module by fiber. When TX LinkLoss is enabled on the remote iMcV-Giga-FiberLinX-II module, a twisted pair fault turns off the fiber port transmitter. This allows the fiber-connected device to detect a link fault. When the fiber uplink port is set to AN, the LED is OFF.
FiberAlert ***WARNING*** Do not enable FiberAlert at both ends. This can cause the fiber link to lock up. When FiberAlert is enabled on the remote module (preferred use), a fault on the receive side of the OPTICS (or UPLINK) port causes the transmitter side to turn off. This allows the fiber connected device to detect a fault in its transmission fiber.
