Configure the EDFA2 line card

You can configure the EDFA2 grid mode, define channel properties, and manually set gain and attenuation parameters for various amplifier stages to achieve desired optical power levels.

The EDFA2 configuration comprises three distinct stages, each performing specific amplification and control functions:

  • Stage 1: Ingress (COM RX Port) This stage includes the EDFA2 Booster 1 (BST1) amplifier, which operates with a fixed gain. Tasks for this stage involve setting the gain value and configuring the gain range.

  • Stage 2: Egress (LINE Port) This stage incorporates the wavelength blocker (WB), EDFA2 Booster 2 (BST2) amplifier, and a Variable Optical Attenuator (VOA) on the LINE TX port. Tasks for this stage include setting the gain value, configuring attenuation for WB slices, setting the EDFA2 Egress gain, adjusting TX VOA attenuation, and performing tilt adjustments.

  • Stage 3: Egress (COM TX Port) This stage is associated with the Pre-amplifier (PRE) and a VOA on the COM TX ports. Tasks for this stage involve setting the gain value, configuring the gain range, and setting VOA attenuation.

Configure the EDFA2 grid mode and ingress amplifier settings

Use this task to configure the EDFA2 grid mode and ingress amplifier settings.

Procedure

Step 1

Configure the EDFA2 to operate in flex grid mode and define its channel properties.

Example:

RP/0/RP0/CPU0:ios(config)
RP/0/RP0/CPU0:ios(config)#hw-module location 0/slot/NXR0 terminal-ampli grid-mode flex channel-id <channel_id> centre-freq <frequency_in_MHz> width <width_in_GHz>
RP/0/RP0/CPU0:ios(config)#commit
RP/0/RP0/CPU0:ios(config)#end

Step 2

Set up the Ingress EDFA2 (Booster 1 amplifier) by configuring its gain range and gain value.

Example:
RP/0/RP0/CPU0:ios#config
RP/0/RP0/CPU0:ios(config)#controller Ots0/slot/0/1 ingress-ampli-gain-range <normal|extended>
RP/0/RP0/CPU0:ios(config)#controller Ots0/slot/0/1 ingress-ampli-gain <gain_value_in_tenths_of_dB>
RP/0/RP0/CPU0:ios(config)#commit

The EDFA2 is configured for flex grid mode with the specified channel properties, and the Ingress EDFA2 (Booster 1 amplifier) gain range and value are set.


Configure the wavelength blocker for egress EDFA gain and VOA

The NCS1K14-EDFA2 line card features a Wavelength Blocker (WB), an advanced optical component designed to provide precise and dynamic management of optical signals that selectively attenuates or blocks specific wavelengths within a fiber optic signal, providing dynamic control to manage individual channels in the amplified signal. The wavelength blocker enables the selective attenuation or blocking of specific wavelengths—or channels—within a fiber optic signal.

You can set the gain for the second-stage amplifier (BST2), define attenuation values for individual Wavelength Blocker (WB) slices, and configure the VOA attenuation for the LINE TX port.

The optical spectrum operates within the C-band, spanning a frequency range of 4.975 THz (from 191.200 THz to 196.175 THz). It is divided into individual 6.25 GHz slices, numbered from 0 to 796. Each slice can be assigned a specific attenuation value to customize the channel’s power profile as needed.

In Release 25.1.1, the attenuation for all slices within the channel must be set manually. In later releases, APC can be enabled to automatically manage slice attenuation, eliminating the need for manual configuration. The specific slices involved depend on the channel's center frequency and width. In release 25.1.1, manual channel configuration is required to activate the system.

Use this task to configure the wavelength blocker.

Before you begin

Ensure you know the channel's center frequency and width.

Procedure

Step 1

Determine the width and number of slices by dividing the channel width (in GHz) by 6.25; for example, a 150 GHz channel width yields 24 slices (150 / 6.25 = 24), while a 50 GHz channel width yields 8 slices (50 / 6.25 = 8). channel width.

Step 2

Locate the channel slice. The EDFA2 can operate over the C-band with a 4.975 THz frequency range (from 191.200 THz to 196.175 THz) and a 6.25 GHz granularity (where the first slice starts at 191.200 THz), the central slice corresponds to the channel's center frequency and determines its slice range; for example, a 191.375 THz center frequency corresponds to central slice 29, covering slices 17 to 40.

Step 3

Use the command controller Ots0/slot/0/0 egress-channel-slice to manually configure the attenuation values for all slices covered by the channel.

Ensure that the attenuation values align with the desired channel profile.

Example:
RP/0/RP0/CPU0:ios#config
RP/0/RP0/CPU0:ios(config)#controller Ots0/slot/0/0 egress-channel-slice <slice_number> attn
<attenuation_value_in_tenths_of_dB>
RP/0/RP0/CPU0:ios#commit

  • Channel center frequency: 191.375 THz

  • Slices involved: 24 slices (150 / 6.25)

  • Central slice:Slice 29

RP/0/RP0/CPU0:ios(config)#commit

Note

 
  • Configure all slices within the channel's range for proper attenuation.

  • Ensure alignment between the channel's physical parameters (center frequency and width) and the WB slice configuration.

Performance monitoring for EDFA2 card

Service providers use performance monitoring (PM) parameters to gather performance data, store it, set thresholds, and report it. This helps with early detection of network issues.

You can configure and retrieve PM counters at intervals of 30 seconds, 15 minutes, or 24 hours. These parameters simplify troubleshooting operations and increase the amount of data that can be collected directly from the equipment.

The tables list the PM counters for the OTS, OTS-OCH, OSC, Optics, CoherentDSP, and OSC optical controllers.

Feature Description

OSC support on EDFA-2 card

Cisco IOS XR Release 25.1.1

The EDFA2 card includes Optical Service Channel (OSC) ports, which enable the creation of a bidirectional communication channel to connect two nodes in a DWDM network. It includes two OSC controllers: one representing the OSC channel towards LINE-TX and the other representing the OSC physical port towards the OSC pluggable.

To establish an OSC channel between two nodes, you configure the Gigabit Ethernet interface, which serves as the packet layer for the OSC channel, along with the OSPF protocol on the nodes. The OSC channel is beneficial for:

  • verifying fiber continuity between two nodes.

  • enabling remote node management.

  • discovering network topology.

  • calculating span loss.

CLI commands are:

  • controller Osc R/S/I/P tx-low-threshold value

  • controller Osc R/S/I/P rx-low-threshold value

  • controller Osc R/S/I/P transmit-power value

  • controller Osc R/S/I/P sec-admin-state { maintenance | normal }

  • controller Osc R/S/I/P shutdown

An Optical Service Channel (OSC) is a bidirectional communication channel that connects two nodes within a DWDM network. The OSC controller is responsible for representing the optical capabilities, configuration, and monitoring of the OSC laser. Its associated Gigabit Ethernet interface acts as the packet layer of an OSC channel representing Ethernet capabilities, configuration, and monitoring.

Functions of OSC

Key functions of the OSC include:

  • Providing a communication channel for traffic originating from a UDC port.

  • Acting as a channel probe to verify fiber continuity between two nodes.

  • Enabling remote node management.

  • Discovering topology

  • Calculating span loss

Operation frequency

The OSC is generated and terminated on each line side, operating at a frequency of 198.50 THz.

OSC controllers in EDFA2 card

The EDFA2 card has two OSC ports. The OSC controllers associated with the OSC optical port on the NCS1K14-EDFA2 line card are denoted as follows:

  • controller osc 0/<slot-id>/0/0 : This represents the OSC channel towards LINE-TX.

  • controller osc 0/<slot-id>/0/4 : This represents the OSC physical port towards the OSC pluggable.

Configure OSC controller parameters

There are multiple parameters for the OSC controllers. You can configure the parameters that are required for the different configuration for an OSC controller on the NCS1K14-EDFA2 line card.

The parameters are:

  • transmit-power

  • sec-admin-state

  • tx-low-threshold

  • rx-low-threshold

  • shutdown

Use this task to configure the OSC parameters:

Procedure

Use the controller osc R/S/I/P command to configure the OSC controller.

  1. Use the transmit-power <value> keyword to specify the transmit-power value.

    Example:

    Line side OSC port:

    RP/0/RP0/CPU0:ios#config
    RP/0/RP0/CPU0:ios(config)#controller osc 0/3/0/0
    RP/0/RP0/CPU0:ios(config-Osc)#transmit-power 20
    Wed Feb 12 13:01:19.298 IST
    WARNING! Changing TX power can impact traffic
    RP/0/RP0/CPU0:ios(config-Osc)#commit

    Pluggable side OSC port:

    RP/0/RP0/CPU0:ios#config
    RP/0/RP0/CPU0:ios(config)#controller osc 0/3/0/4
    RP/0/RP0/CPU0:ios(config-Osc)#transmit-power -100
    Wed Feb 12 13:02:16.123 IST
    WARNING! Changing TX power can impact traffic
    RP/0/RP0/CPU0:ios(config-Osc)#commit

    Note

     

    To ensure the protection of the OSC pluggable receiver, regardless of the configured transmit power on the OSC controller located at 0/slot-id/0/4, the maximum transmit power will be limited to -9 dBm.

  2. Use the sec-admin-state { maintenance | normal } keyword to configure the administrative state of the controller as maintenance or normal.

    Example:

    Line side OSC port:

    RP/0/RP0/CPU0:ios#config
    RP/0/RP0/CPU0:ios(config)#controller osc 0/3/0/0
    RP/0/RP0/CPU0:ios(config-Osc)#sec-admin-state normal 
    RP/0/RP0/CPU0:ios(config-Osc)#commit

    Pluggable side OSC port:

    RP/0/RP0/CPU0:ios#config
    RP/0/RP0/CPU0:ios(config)#controller osc 0/3/0/4
    RP/0/RP0/CPU0:ios(config-Osc)#sec-admin-state normal 
    RP/0/RP0/CPU0:ios(config-Osc)#commit
  3. Use the tx-low-threshold <value> keyword to specify the low transmit power threshold value.

    Example:

    Line side OSC port:

    RP/0/RP0/CPU0:ios#config
    RP/0/RP0/CPU0:ios(config)#controller osc 0/3/0/0
    RP/0/RP0/CPU0:ios(config-osc)#tx-low-threshold 20 
    RP/0/RP0/CPU0:ios(config)#commit

    Pluggable side OSC port:

    RP/0/RP0/CPU0:ios#config
    RP/0/RP0/CPU0:ios(config)#controller osc 0/3/0/4
    RP/0/RP0/CPU0:ios(config-osc)#tx-low-threshold 20 
    RP/0/RP0/CPU0:ios(config)#commit
  4. Use the rx-low-threshold <value> keyword to specify the low receive power threshold value.

    Example:

    Line side OSC port:

    RP/0/RP0/CPU0:ios#config
    RP/0/RP0/CPU0:ios(config)#controller osc 0/3/0/0
    RP/0/RP0/CPU0:ios(config-osc)#rx-low-threshold 50 
    RP/0/RP0/CPU0:ios(config)#commit

    Pluggable side OSC port:

    RP/0/RP0/CPU0:ios#config
    RP/0/RP0/CPU0:ios(config)#controller osc 0/3/0/4
    RP/0/RP0/CPU0:ios(config-osc)#rx-low-threshold 50 
    RP/0/RP0/CPU0:ios(config)#commit
  5. If you want to disable the configuration of the controller, use the shutdown keyword.

Example:

Line side OSC port:

RP/0/RP0/CPU0:ios#config
RP/0/RP0/CPU0:ios(config)#controller osc 0/3/0/0 shutdown 
RP/0/RP0/CPU0:ios(config)#commit

Pluggable side OSC port:

RP/0/RP0/CPU0:ios#config
RP/0/RP0/CPU0:ios(config)#controller osc 0/3/0/4 shutdown 
RP/0/RP0/CPU0:ios(config)#commit

Verify OSC controller configurations

Use these steps to verify various OSC controller configurations:

Procedure

Example:

RP/0/RP0/CPU0:ios#show controllers description | In Osc
Wed Feb 12 12:59:02.294 IST
Osc0/3/0/0                  up               
Osc0/3/0/4                  up               

Step 4

Use the show controllers osc R/S/I/P command to display the status and configuration information of the OSC controllers on the NCS1K14-EDFA2 card.

Example:

sh controllers osc 0/3/0/0
Wed Feb 12 13:01:44.325 IST

 Controller State: Up

Step 5

Use the command show interfaces gigabitEthernet R/S/I/P to view the parameters of the Gigabit Ethernet interface associated with the OSC channel.

Example:

RP/0/RP0/CPU0:ios#sh interfaces gigabitEthernet 0/3/0/5 
Wed Feb 12 13:05:29.153 IST
GigabitEthernet0/3/0/5 is up, line protocol is up 
  Interface state transitions: 1
  Hardware is GigabitEthernet, address is c4ab.4d1b.9380 (bia c4ab.4d1b.9380)

  Last input Unknown, output Unknown
  Last clearing of "show interface" counters Unknown
  5 minute input rate 0 bits/sec, 0 packets/sec
  5 minute output rate 0 bits/sec, 0 packets/sec

Step 6

Use the command show ipv4 interface brief to view the IPv4 address of a Gigabit Ethernet interface.

Example:
show ipv4 interface brief 
Wed Feb 12 13:05:41.784 IST

Interface                      IP-Address      Status          Protocol Vrf-Name
GigabitEthernet0/3/0/5         192.0.2.1         Up              Up       default 
MgmtEth0/RP0/CPU0/0            209.165.201.3     Up              Up       default 
PTP0/RP0/CPU0/0                unassigned        Shutdown        Down     default 
MgmtEth0/RP0/CPU0/1            10.127.126.176    Up              Up       default 

The Gigabit Ethernet interface must be in Up state for the OSC laser to turn up. When the node comes up, the Gigabit Ethernet interface turns to Down state. Run these commands on the Gigabit Ethernet interface to bring it up.

RP/0/RP0/CPU0:ios#config
RP/0/RP0/CPU0:ios(config)#no interface gigabitEthernet 0/3/0/5  shutdown
RP/0/RP0/CPU0:ios(config)#commit

Step 7

Use the commands show controllers switch summary and show controllers switch statistics to view the status OSC ports in the NCS1K14-EDFA2 line card.

Example:

RP/0/RP0/CPU0:ios#show controllers switch summary 
Wed Feb 12 13:06:07.130 IST

UDC OSC connection

The OSC channel carries both UDC and OSC traffic. The EDFA2 card has a single OSC port that supports one OSC channel at a time. To carry UDC traffic over OSC channel, attach a UDC port to a specific OSC port on the EDFA2 card by using a CLI command.

The NCS 1014 chassis does not have dedicated UDC ports but includes two PTP ports. You can convert these PTP ports into UDC ports and connect them to the OSC channel using a CLI command. See Convert PTP ports to UDC ports.


Note


The NCS 1014 chassis has only two PTP ports, you can connect maximum 2 ports on two EDFA2 cards.


Convert PTP ports to UDC ports

Follow this step to convert the PTP ports available in the NCS 1014 controller into UDC ports and attach them to the Ethernet port corresponding to the OSC channel.

Procedure

Step 1

Enter the command hw-module location to convert the PTP ports to UDC ports and attach them to the GigabitEthernet interface of the OSC.

Example:

The output shows the conversoin of two PTP ports into UDC ports.

RP/0/RP0/CPU0:ios(config)#hw-module location 0/RP0/CPU0 ptp 0 port-mode udc attach interface GigabitEthernet 0/0/0/5
RP/0/RP0/CPU0:ios(config)#hw-module location 0/RP0/CPU0 ptp 1 port-mode udc attach interface GigabitEthernet 0/1/0/5

Step 2

Enter the command show controllers switch summary to verify the UDC ports information. After converting the PTP ports to UDC, check the link ports 2 and 6 for UDC information.

Step 4

(Optional) Use the clear controller switch statistics location to reset the statistics information.

  1. Check for the applicable locations for controller statistics.

    Example:
    RP/0/RP0/CPU0:ios#clear controller switch statistics location ?
      0/0/NXR0    Fully qualified location specification
      0/1/NXR0    Fully qualified location specification
      0/2/NXR0    Fully qualified location specification
      0/3/NXR0    Fully qualified location specification
      0/RP0/CPU0  Fully qualified location specification
      WORD        Fully qualified location specification
  2. Use the controller location, 0/RP0/CPU0, to clear the switch statistics information for the UDC ports.

    Example:
    RP/0/RP0/CPU0:ios#clear controller switch statistics location 0/RP0/CPU0
    Mon Jul 21 13:26:31.913 IST

How OSC UDC connection works

The process involves these stages:

  • After you convert the PTP ports to UDC ports using CLI configuration, the NCS 1014 maps each UDC port to its OSC channel and sends packets from each UDC port through its channel.

  • The packets received on the CPU-OSC interface will be transmitted as "untagged" over the OSC channel, whereas UDC packets will be transmitted as "tagged".

  • When two OSC ports are directly connected between nodes, the NCS 1014 uses the same tagging method for both sent and received packets.


Note


Traffic will be interrupted during a controller cold reset or during a software upgrade when the controller undergoes a cold reset due to a BIOS or any other FPD upgrade. UDC traffic is not impacted during a controller warm reset.

  • Embedded optical coupler optical splitter.

  • The interoperability function with a EDFA2 line card aggregate signals from transponders.

  • Seperate port for coherent probe support.

  • USB 2.0 for inventory, PD reading, and LED control.

  • RX and TX ports for OCH and OMS contoller channels.

  • FPD upgrade support.

Limitations
  • Loopback is not supported.

  • Passive line card reload not supported.

Performance monitoring for NCS1K-MD-32x-CE

Service providers use performance monitoring (PM) parameters to gather performance data, store it, set thresholds, and report it. This helps with early detection of network issues.

You can configure and retrieve PM counters at intervals of 30 seconds, 15 minutes, or 24 hours. These parameters simplify troubleshooting operations and increase the amount of data that can be collected directly from the equipment.

You can view and configure the performance monitoring parameters for optics on OCH and OMS controllers.

The table list the PM counters for the OCH and OMS controllers.
