Usage Guidelines

For the interface-path-id argument, use the following guidelines:

  • If specifying a physical interface, the naming notation is rack/slot/module/port/subport. The slash between values is required as part of the notation. An explanation of each component of the naming notation is as follows:

    • rack: Chassis number of the rack.

    • slot: Physical slot number of the line card.

    • module: Module number.

    • port: Physical port number of the interface.

    • subport: Physical port number of the sub-interface.

Usage Guidelines


Note

The enhanced FEC mode supported on the Cisco CRS Router (ITU-T G.975.1 I.7) and the Cisco ASR 9000 Series Router (ITU-T G.975.1 I.4) are different and therefore, incompatible. To support interoperability of DWDM between these routers, standard FEC must be configured.

The g709 fec command can be used only when the DWDM controller port is in the out-of-service administrative state. You stop operation using the admin-state out-of-service command.

The G.709 wrapper must be enabled to enable forward error correction (FEC) mode on the controller.

Standard FEC is the default mode; therefore, if you use the no g709 fec command, standard FEC is used.

To display the FEC mode, use the show controller dwdm command.

Command Description

controller dwdm

Configures a DWDM controller.  

transport-mode (WAN/OTN)

To specify the transport mode for a 10-Gigabit Ethernet interface, use the transport-mode command in interface configuration mode. To return to the default mode, use the no form of this command.

transport-mode {wan | otn bit-transparent {opu1e | opu2e}}

Syntax Description

wan

Configures the interface for 10GBASE-W WAN SONET/SDH (9.95328Gb/s) transport.

otn bit-transparent

Configures the interface for 10-Gigabit Ethernet over Optical Transport Network (ITU-T G.709) with 10GBASE-R transparently mapped into OTU-2.

opu1e

Configures the interface for 10GBASE-R over OPU1e without fixed stuffing (11.0491Gb/s).

opu2e

Command History

Release

Modification

Release 3.9.0

This command was introduced.

Usage Guidelines

Three modes are supported for a 10-Gigabit Ethernet interface: LAN, WAN, or OTN on these Ethernet line cards and Modular Port Adaptors (MPAs):

  • 2-Port 10-Gigabit Ethernet, 20-Port Gigabit Ethernet Combination line card (A9K-2T20GE-B and A9K-2T20GE-L)

  • 8-Port 10-Gigabit Ethernet line card (A9K-8T-L, -B, or -E)

  • 16-Port 10-Gigabit Ethernet SFP+ line card (A9K-16T/8-B and A9K-16T/8-B+AIP)

  • 24-Port 10-Gigabit Ethernet line card (A9K-24X10GE-SE/TR)

  • 36-Port 10-Gigabit Ethernet line card (A9K-36X10GE-SE/TR)

  • 2-Port 10-Gigabit Ethernet Modular Port Adaptor (A9K-MPA-2x10GE)

  • 4-Port 10-Gigabit Ethernet Modular Port Adaptor (A9K-MPA-4x10GE)

  • 8-Port 10-Gigabit Ethernet Modular Port Adaptor (A9K-MPA-8x10GE)

Limitation:

On TenGig breakout interface of Cisco ASR 9000 High Density 100GE Ethernet (8x100G and 4x100G) line cards, configure same transport mode (OPU1E or OPU2E) on both ends of the interface. Different transport modes at both ends results in flapping of the interface status and the router console displays continuous interface UP/DOWN messages.

If you want to configure the interface for DWDM support, configure the 10-Gigabit Ethernet interface for OTN transport mode.

These 40GE MPAs support LAN and OTU3 modes:

  • A9K-MPA-1x40GE

  • A9K-MPA-2x40GE


Note

Before Cisco IOS XR Software Release 4.2.0, only transport-mode wan was used under the interface configuration mode to set WAN PHY controller. Then, both Operational Mode and Configuration Mode would be changed to WAN Mode.

After Cisco IOS XR Software Release 4.2.0, you can use transport-mode wan under the interface configuration mode to use basic function of WAN PHY. In addition, we can use wanmode on under the wanphy controller mode to use alarm function and BIP counter.


Note

On the Cisco A9K-4T16GE-TR and Cisco A9K-4T16GE-SE line cards, mixed use of LAN and WAN transport modes is not supported due to hardware limitation. In other words, WAN PHY is configured on all the four 10GigE ports to be operated either in LAN mode or WAN mode for 10 GigE ports 16, 17, 18 and 19.

On applying the configuration change from LAN to WAN or back on port 16, the same configuration shall be applied on all the other 10 GigE ports 17, 18, and 19. The ports 17, 18 or 19 cannot be used to make configuration changes using the transport-mode command. Also, the running configuration shows the configuration change only on port 16.

RP/0/RSP0/CPU0:router# config
RP/0/RSP0/CPU0:router(config)# interface 10gigabitethernet 0/1/0/1
RP/0/RSP0/CPU0:router(config-if)# transport-mode wan 
RP/0/RSP0/CPU0:router(config-if)# commit

The following configuration is needed to operate in WAN PHY mode: 


RP/0/RSP0/CPU0:router# config
RP/0/RSP0/CPU0:router(config)# controller wanphy <>
RP/0/RSP0/CPU0:router(config)# wanmode on 
RP/0/RSP0/CPU0:router(config)# commit

This example shows how to configure a DWDM interface using OTN transport: 


RP/0/RSP0/CPU0:router# config 
RP/0/RSP0/CPU0:router(config)# interface 10gigabitethernet 0/5/0/7/0 
RP/0/RSP0/CPU0:router(config-if)# transport-mode otn bit-transparent opu1e
RP/0/RSP0/CPU0:router(config-if)# commit

The following additional configuration is also needed: 


RP/0/RSP0/CPU0:router# config
RP/0/RSP0/CPU0:router(config)# controller dwdm <>
RP/0/RSP0/CPU0:router(config)# admin-state in-service 
RP/0/RSP0/CPU0:router(config)# commit

This example shows how to return the interface configuration to its default LAN mode from OTN or WAN PHY mode: 


RP/0/RSP0/CPU0:router# config
RP/0/RSP0/CPU0:router(config)# interface 10gigabitethernet 0/1/0/1
RP/0/RSP0/CPU0:router(config-if)# no transport-mode 
RP/0/RSP0/CPU0:router(config-if)# commit

Command Description

controller wanphy

Enters WAN physical controller configuration mode in which you can configure a 10-Gigabit Ethernet WAN PHY controller.  

wavelength

To set the wavelength on a DWDM controller to a specific ITU channel or to define a specific frequency or wavelength to a DWDM controller, use the wavelength command in DWDM configuration mode. To return the wavelength to its default value, use the no form of this command.

Note

ASR 9000 64-bit (eXR) does not support the wavelength 100MHz-Grid frequency command.

wavelength { 50GHz-grid {channel-number | frequency frequency | update wavelength}} | {100MHz-grid frequency frequency}

Syntax Description

50GHz-grid

Specifies 50-GHz frequency grid.
100MHz-grid

Specifies 100-GHz frequency grid.
channel-number

ITU channel number. ITU channel numbers have predefined frequencies as defined by Multi Source Agreement (MSA) International Telecommunication Union (ITU) grid.

  • The range is 1 to 100 for conventional band (C-band)

frequency frequency

Keyword that specifies the frequency for the DWDM controller.

Enter the 5-digit frequency value in the range of 19115 to 19610 GHz. For example, enter frequency 19580 to specify 195.8 THz.

update wavelength

Keyword that defines a specific wavelength for the DWDM controller.

Enter the 7-digit frequency value in the range of 1528773-1563863 micrometers (mm). For example, enter update 1532290 to specifiy 1532.29 nanometers (nm).

Command Default

The default channel is 96.

Modification

Release 4.3.0

This command was introduced.

Release 5.3.2

50 GHZ or 100 GHz options were introduced.

Usage Guidelines

You can set the wavelength to a specific ITU channel, that is represented by a channel number in the Multi Source Agreement (MSA) ITU grid.

The spacing between wavelengths is 50 GHZ or 100 GHz. Use the show controllers dwdm command with the wavelength-map keyword to view the channel numbers and wavelengths that are supported for a particular controller.

The controller must be in the out-of-service state before you can use the wavelength command.
