Configure Controllers

Controllers

A controller identifier is a location value that

  • uses the Rack/Slot/Instance/Port format,

  • identifies the optical controller that you configure or display, and

  • uses values such as 0/1/0/1 for a specific controller location.

OTS controllers

An Optical Transport Section (OTS) controller is an optical interface controller that

  • stores the optical parameters for the OTS interfaces,

  • exposes parameters based on hardware capabilities such as photodiode, variable optical attenuator (VOA), amplifier, optical channel monitor (OCM), and

  • supports receive and transmit section parameters when the hardware supports them.

When an OTS controller is created, each hardware capability is enabled or disabled. For example, when a photodiode is present, the OTS controller can read the total optical power.

You can configure OTS parameters such as low power threshold, VOA attenuation set point, amplifier gain range, amplifier tilt, amplifier gain set point, channel power, and safety control mode. OTS interface descriptions cannot be added in the same way as descriptions on the optical amplifier module.

Span loss calculation

Span loss calculation is an automatic software function that

  • calculates span losses between NCS 1001 systems,

  • uses transmit and receive total power on EDFA ports, and

  • supports protected or nonprotected linear topologies, with or without intermediate inline amplifier (ILA) nodes.

The feature is available for the OTS controller and can be enabled or disabled through the hw-module configuration. The calculation runs automatically every five minutes and when there is a configuration change.

Calculation methods and parameters

Span loss calculation first uses remote node configuration and, if unavailable, uses OSC through OSPF.

The show controllers ots command displays these span loss parameters for EDFA cards:

  • RX Span Loss

  • TX Span Loss

Limitation

Span loss calculation considers total power at the transmit end and receive end on EDFA ports. If the PSM card is connected to the span, such as in a path-protection topology, the span boundaries are assumed to be the closer EDFA ports.

Configure span loss calculation

Configure span loss calculation across the local and remote NCS 1001 systems that participate in the optical span.

Table 3. Feature History

Feature Name

Release Information

Description

IPv6 Support for Span Loss Calculation

Cisco IOS XR Release 7.10.1

You can now perform span loss calculations on IPv6 spans connecting two NCS 1001 nodes. As a result, the advantages of larger address space can be leveraged by configuring IPv6 addresses on the management interfaces used for communication between the two nodes.

Starting with Cisco IOS XR Release 7.10.1, span loss calculation supports IPv6 addresses in addition to IPv4 addresses. The IPv6 addresses must be configured on the management interfaces of IPv6 enabled NCS 1001 nodes.

The feature uses DCN or OSC (OSPF) so NCS systems can exchange power measurements needed to calculate span losses. In both cases, you must enable the feature and specify the node type (TERM or ILA) on each system.


Note

Configure either IPv4 or IPv6, but not both, for span loss calculation.

Span loss calculation with IPv6 is not supported on OSC management interfaces of NCS 1001 nodes. Even with OSPFv3, neighbor discovery returns the IPv4 router ID instead of the IPv6 router ID. This prevents automatic IPv6 address resolution.

Procedure

Step 1

Enable span loss calculation on the TERM node. See Enable span loss calculation on a TERM node.

Step 2

Enable span loss calculation on the ILA node, if the span includes an ILA node. See Enable span loss calculation on an ILA node.

Step 3

Configure the remote node with IPv4 or IPv6 addresses. See Configure a span loss remote node with IPv4 or Configure a span loss remote node with IPv6.

Step 4

Review topology examples for terminal-to-terminal and terminal-to-ILA-to-terminal designs. See Span loss calculation use cases.

Step 5

Wait for 5 minutes for the first automatic calculation or trigger the calculation manually. See Trigger span loss calculation.

Display span loss calculation

After the feature is enabled and the first calculation runs, the show controllers ots command displays RX Span Loss and TX Span Loss. These values are calculated from the difference between TX Total Power and RX Total Power at the span edge.

Procedure

Step 1

Display span loss for a TERM node line port.

Example:

#show controllers ots 0/1/0/1
RX Span Loss = 15.20 dB
TX Span Loss = 14.80 dB

Step 2

For an ILA node, display RX Span Loss on the line port and TX Span Loss on the COM port.

Example:

#show controllers ots 0/3/0/1
RX Span Loss = 12.40 dB
#show controllers ots 0/3/0/0
TX Span Loss = 11.90 dB

Dual IP addresses

Dual independent XR interfaces are management Ethernet interfaces that

  • connect two Ethernet interfaces to different switches in different or same subnets,

  • use separate MGMT RJ45 and optical SFP MGMT ports to the CPU from Release 6.5.1, and

  • support management connectivity through MgmtEth0/RP0/CPU0/0 and MgmtEth0/RP0/CPU0/1 .

Management Ethernet interfaces

  • MgmtEth0/RP0/CPU0/0 represents the RJ45 port.

  • MgmtEth0/RP0/CPU0/1 represents the SFP port.

iPXE is not supported at power-on over the new optical interface. If you upgraded from a previous release and used only SFP, management connectivity may be lost. In this case, configure the system through the console port. Before using both interfaces, upgrade the BIOS and reload the 0/RP0 location.

OTS OCH controllers

An Optical Transport Section Optical Channel (OTS OCH) controller is a channel-level controller that

  • represents the optical channel monitor (OCM) device on an OTS optical interface,

  • provides channel granularity over the OTS interface, and

  • stores wavelength information with controller numbers that start at 1 and match ITU channel identifiers.

The system creates 48 OTS OCH controllers for a 100 GHz grid and 96 OTS OCH controllers for a 50 GHz grid.
