Interface and Hardware Component Command Reference for the Cisco NCS 6000 Series Routers

admin-state

To configure the transport administration state on a DWDM port, use the admin-state command in DWDM configuration mode. To return the administration state from a DWDM port to the default, use the no form of this command.

Note

ASR 9000 64-bit (eXR) does not support the admin-state in-service and admin-state out-of-service commands.

admin-state {in-service | maintenance | out-of-service}

Syntax Description


in-service	Places the DWDM port in In Service (IS) state, to support all normal operation.
maintenance	Places the DWDM port in Out of Service Maintenance (OOS-MT) state to perform configuration, while the laser and G.709 framer remain up.
out-of-service	Places the DWDM port in Out of Service (OOS) state. The laser is turned off and all traffic flow is stopped. This is the default.

Command Default

Out-of-service is the default transport administration state.

Command Modes

DWDM configuration

Command History


Release	Modification
Release 3.9.0	This command was introduced. It replaced the laser and shutdown (DWDM) commands.
Release 3.9.1	The maintenance keyword was added.
Release 3.9.0	This command was introduced.
Release 5.2.3	This command was introduced.

Usage Guidelines

When you configure admin-state maintenance , the DWDM port is placed in OOS-MT state and any configuration of maintenance disable for the port can be overridden. The laser for the port and the G.709 framing remains enabled, and Fast Re-Route (FRR) is triggered. This form of the command is usually used in FRR context for traffic to move over backup path while maintenance is going on.

When you configure admin-state out-of-service , the DWDM port is placed in OOS state. The laser is turned off, traffic flow is stopped, and proactive protection is disabled. However, configuration changes can still be made on the port.

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. A physical layer interface module (PLIM) is always 0.
- port: Physical port number of the interface.
- subport: Physical port number of the sub-interface.
If specifying a virtual interface, the number range varies, depending on interface type.

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 OC-768c/STM-256c DWDM PLIM on the Cisco CRS Router supports enhanced FEC mode only. Disabling FEC or enabling standard FEC is not supported.

The g709 fec command can be used only when the DWDM controller port is not operational. In Cisco IOS XR releases prior to Cisco IOS XR Release 3.9.0, you stop operation using the shutdown (DWDM) command. Beginning in Cisco IOS XR Release 3.9.0, 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.

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

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.

Related Commands

Command	Description
show controller dwdm	Displays optical parameters, G.709 alarms and counters, and register and module information for a DWDM controller.

rx-los-threshold

To configure the transponder receive power threshold on a DWDM controller, use the rx-los-threshold command in DWDM configuration mode. To return the transponder receive power threshold to its default value, use the no form of this command.

rx-los-threshold power-level

Syntax Description


`power-level`	Receive power level in units of 0.1 dBm. Values can range from -350 to 50, which corresponds to a LOS threshold range of -35 dBm to 5 dBm.

Command Default

The default power-level is-19.5 dBm.

Command Modes

DWDM configuration

Command History


Release	Modification
Release 3.3.0	This command was introduced. It is supported only on the OC-768c/STM-256c DWDM PLIM.
Release 3.6.0	The value for the `power-level` argument was changed from -200 to 0, to -350 to 50.
Release 5.2.3	This command was introduced.

Usage Guidelines

The rx-los-threshold command can be used only when the DWDM controller port is not operational. In Cisco IOS XR releases prior to Cisco IOS XR Release 3.9.0, you stop operation using the shutdown (DWDM) command. Beginning in Cisco IOS XR Release 3.9.0, you stop operation using the admin-state out-of-service command.

The rx-los-threshold command is applicable only to the OC-768c/STM-256c DWDM PLIM.

Command History


Release	Modification
Release 3.3.0	This command was introduced.
Release 3.4.0	The display of the TTI strings was added.
Release 3.6.0	Tunable dispersion compensator (TDC) information was added.
Release 3.9.0	The Transport Admin State output field was added, and the output for the FEC Mode field was modified to display the type of Enhanced FEC configured.
Release 3.9.1	The srlg and proactive status keywords were added.
Release 3.9.0	This command was introduced.
Release 5.2.3	This command was introduced.
Release 5.3.0	The command output was enhanced to capture whether VTXP is enabled on an interface or not.
Release 5.3.1	g709 standard FEC mode is enabled by default.

Usage Guidelines

DWDM interfaces with g709 capability(enabled) and FEC(enabled) would report with Threshold Crossing Alerts (TCA) for Error Correction based PREFEC version of SD and SF BER. The thresholds act independent of FRR thresholds. If FRR is also enabled, then PREFEC thresholds are expected to be manually tuned to provide an early warning before the protection is triggered. The information regarding PREFEC_SD and PREFEC_SF are made available for the show controller dwdm interface-path-id g709 command. 10 GigE and 40 GigE DWDM interfaces support standard FEC and enhanced i.4 and i.7 FEC modes while 100GigE supports standard FEC.

This table describes selected fields from the show controllers dwdm command output.

Table 1. show controllers dwdm Command Output Field Descriptions
Field	Description
AIS	Number of alarm indication signal (AIS) alarms. AIS is a signal sent downstream as an indication that an upstream defect has been detected.
Alarm reporting enabled for	Lists the alarms that are enabled for reporting.
Asserted Alarms	Alarms indicated to be reported by the user.
BDI	Number of backward defect indication (BDI) alarms. The BDI is a single bit that conveys information regarding signal failure in the upstream direction.
BER thresholds	Values of the configured bit error rate thresholds.
BIP	Number of bit interleaved parity alarms. The BIP is comprised of one byte and is used for error detection. It is computed over the entire optical channel payload unit (OPU).
Controller State	Status of the controller.
Detected Alarms	Alarms detected by the hardware.
EC	Corrected code words. This is the number of words corrected by the FEC and is displayed as a per second rate.
FEC Mode	Indicates the forward error correction (FEC) mode for the controller. This can be Disabled, Enhanced FEC G.975.1 1.7 (Default), or Standard FEC. This can be Disabled, Enhanced FEC G.975.1 1.4, or Standard FEC (Default).
IAE	Number of incoming alignment errors (IAE).
LCK	Number of upstream connection locked alarms. LCK is a signal sent downstream as an indication that upstream the connection is locked, and no signal is passed through.
LOF	Number of OTU loss of frame (LOF) alarms.
LOM	Number of OTU loss of multiframe (LOM) alarms.
Loopback	Loopback status. Indicates whether or not loopback is enabled and the type of loopback enabled.
LOS	Number of OTU loss of signal (LOS) alarms. The LOS threshold is set using the rx-los-threshold command. If the receive optical power is less than or equal to this defined threshold, the optical LOS alarm is raised.
OCI	Number of open connection indication alarms. OCI is a signal sent downstream as an indication that upstream the signal is not connected to a trail termination source.
ODU	Optical channel data unit alarms.
OTU	Optical transport unit overhead alarms.
OTU TTI Expected	Value of the expected TTI.
OTU TTI Received	Value of the received TTI.
OTU TTI Sent	Value of the transmit trail trace identifier (TTI).
PTIM	Number of payload type identifier mismatch alarms. This occurs when there is a mismatch between the way the ITU-T G.709 option is configured on the PLIM at each end of the optical span.
TDC Info	Tunable Dispersion Compensator (TDC) information.
Transport Admin State	Current status of the port as set by the admin-state command. Possible values are: IS (In-Service) and OOS (Out-of-Service).
UC	Uncorrectable code words. This is a raw counter.
Pre-FEC BER	Pre - bit error rate (BER) forward error correction (FEC). The pre-FEC BER is calculated using pre-forward error correction (FEC) error counts.
Q	The general signal quality bit error rate (BER) per voltage. The Q and Q margin are calculated using the Pre-FEC BER.
Q Margin	The general signal quality bit error rate (BER) per voltage. The Q and Q margin are calculated using the Pre-FEC BER.
Operational Mode	Indicates whether the tunable dispersion compensator (TDC) operational mode option is set to Auto or Manual.
Status	Indicates whether the tunable dispersion compensator (TDC) is in the acquiring state or locked state. The status is invalid if there is a major alarm.
Dispersion Setting	Indicates a value between –700 and +700 packets per second (pps). The dispersion setting is read from the optics module after the tunable dispersion compensator (TDC) has locked.
Reroute Control	Not used.
Reroute BER	Not used.

See Table 2 for a description of the optics fields.

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.
