The following table lists the AINS states.

If there are any service-affecting alarms when AINS is runring on ethernet or optics controllers, the AINS state moves to Pending state. When the alarms are cleared, the AINS state moves to Running state.

The AINS soak time period restarts when there are line card reloads, XR reloads, line card warm reloads, power cycles, or alarm conditioning.

You can configure the soak time period to be between 1 minute to 48 hours.

All alarms are suppressed during the AINS state. When the optical and ethernet alarms are raised on the port during the soak time period, the AINS state moves to Pending. These alarms are not displayed in the output of the show alarms brief card location 0/RP0/CPU0 active command but in the output of the show alarms brief card location 0/RP0/CPU0 conditions command. When all the alarms clear, the soak time period starts, and the AINS state moves to Running. When the soak time period expires, the port moves to IS state.

To configure AINS on a muxponder, use the following command:

configure

hw-module location location mxponder client-port-ains-soak hours hours minutes minutes

commit

The following is a sample in which all client ports are configured with AINS with soak time period specified to be 15 minutes.

RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#hw-module location 0/3 mxponder client-port-ains-soak hours 0 minutes 15
RP/0/RP0/CPU0:ios(config)#commit

To configure AINS on a muxponder slice, use the following command:

configure

hw-module location location mxponder-slice slice-number client-port-ains-soak hours hours minutes minutes

commit

The following is a sample in which slice 0 client ports are configured with AINS with soak time period specified to be 40 minutes.

RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#hw-module location 0/3 mxponder-slice 0 client-port-ains-soak hours 0 minutes 40
RP/0/RP0/CPU0:ios(config)#commit

To disable AINS on all muxponder client ports, set the hours and minutes to 0. Use the following commands:

configure

hw-module location location mxponder client-port-ains-soak hours hours minutes minutes

commit

The following is a sample in which AINS is disabled on all client ports.

RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#hw-module location 0/3 mxponder client-port-ains-soak hours 0 minutes 0
RP/0/RP0/CPU0:ios(config)#commit

To disable AINS on a muxponder slice, set the hours and minutes to 0. Use the following command:

configure

hw-module location location mxponder-slice slice-number client-port-ains-soak hours hours minutes minutes

commit

The following is a sample in which AINS is disabled on all client ports of slice 0.

RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#hw-module location 0/3 mxponder-slice 0 client-port-ains-soak hours 0 minutes 0
RP/0/RP0/CPU0:ios(config)#commit

The AINS Soak field in the output indicates the current state of AINS. The current state can be None, Pending, or Running. The Total Duration field indicates the total soak time period that is configured. The Remaining Duration field indicates the soak time that remains, after which, the AINS state moves to None.

This example displays the ethernet controller statistics with AINS Soak in running state.

The following table lists the FEC states for the Ethernet controller.

FEC configuration is automatically enabled for only the pluggables that support Auto-FEC. If you manually configure FEC, the manual configuration overrides the Auto-FEC.

The supported pluggables for Auto-FEC are:

• QSFP-100G-SR4-S

• QSFP-100G-CWDM4-S

• QSFP-100G-SM-SR

• QSFP-100G-AOC-1M

• QSFP-100G-AOC-3M

• QSFP-100G-AOC-10M

• QDD-400-AOC15M

• QDD-400G-FR4-S

• QSFP-100G-ER4L

• QDD-400G-DR4-S

• QDD-400G-LR8-S

The LR4 pluggable is a 1310nm long range band pluggable that does not require you to enable FEC.

The software automatically enables FEC mode on the pluggables installed in the Cisco NCS 1004. When you upgrade the software of an NCS 1004 with pluggables in the FEC disabled mode, traffic is affected.

The following sample shows the running FEC configuration on the LR4 pluggable:

The following table lists the FEC states for the coherentDSP controllers.

Q-margin is an important optical parameter that characterizes the health of an optical link. The Q-margin value is calculated based on the average bit error rate (BER) in the optical link.

Enhanced Q-Margin Support

From Release 7.3.1 onwards, enhanced Q-Margin is supported for Forward error correction (FEC) and performance monitoring on CoherentDSP controllers for 1.2T and 1.2TL cards. Enhanced Q-margin provides a better error free signal in the optical link. The enhanced Q-margin value is calculated based on the maximum number of errors per frame. An attribute that is called instantaneous Q-margin is displayed in the output of the show controllers coherentDSP command. The lower the delta value between the instantaneous Q-margin value with the Q-margin value, the better the FEC performance of the NCS 1004 system.

To view Q-margin and enhanced Q-margin values for FEC on CoherentDSP controllers, see Verifying FEC on CoherentDSP Controllers.

To view Q-margin and enhanced Q-margin values for performance monitoring on CoherentDSP controllers, see Configuring PM Parameters.

To configure FEC on the CoherentDSP controller, use the following command:

The following diagram describes the recommended topology for link verification:

The following steps describe the sequence for link verification using this topology:

1. Both the near-end and far-end clients have the LOCAL-FAULT alarm if the trunk is up on both the ends.

2. Enable idle ingress on the near-end client. The idle frame transmits toward the trunk link and reaches the far-end client. The LOCAL-FAULT alarm is then cleared on the far-end client.

3. As the far-end client has fiber loop, the idle frame is inserted again into the same client RX toward the trunk link and reaches the near-end client. The LOCAL-FAULT alarm is then cleared on the near-end client as well.

4. When you enable idle insertion on any client and in any direction, the idle frame transmits in loop similar to this topology and all the LOCAL-FAULT and the REMOTE-FAULT alarms are cleared.

5. The link can be monitored after all the alarms are cleared. The link has a problem if any alarm is reported during the link test.

Before You Begin:

• Do not configure idle frame insertion with hold-off timer.

• Do not configure PRBS on the trunk.

You can configure this feature by using the following commands:

configure

controller hundredGigECtrlr Rack/Slot/Instance/Port

insert-idle ingress

insert-idle egress

commit

end

The following is a sample for enabling the idle ingress and idle egress in 100GE controllers:

RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#controller hundredGigECtrlr 0/2/0/2
RP/0/RP0/CPU0:ios(config-eth-ctrlr)#insert-idle ingress

RP/0/RP0/CPU0:ios(config-eth-ctrlr)#commit
RP/0/RP0/CPU0:ios(config-eth-ctrlr)#end

You can disable this feature by using the following commands:

configure

controller hundredGigECtrlr Rack/Slot/Instance/Port

no insert-idle ingress

no insert-idle egress

commit

end

To verify the idle ingress and idle egress that is configured on the Ethernet controllers, use the following command:

You can configure DHCPv6 client on management Ethernet interfaces. You can configure different DHCPv6 client options to differentiate between clients as required. The different DHCPv6 client options are also configured to differentiate how a DHCPv6 client communicates with a DHCPv6 server. The different DHCPv6 client options that can be configured are:

• DUID: If the DUID DHCPv6 client option is configured on an interface, DHCPv6 client communicates with the DHCPv6 server through the link layer address.

• Rapid Commit: If the Rapid Commit DHCPv6 client option is configured on an interface, DHCPv6 client can obtain configuration parameters from the DHCPv6 server through a rapid two-step exchange (solicit and reply) instead of the default four-step exchange (solicit, advertise, request, and reply).

• DHCP Options: The various other DHCPv6 options that can be configured on a DHCPv6 client are:

  • Option 15: Option 15 is also known as the User Class option and it is used by a DHCPv6 client to identify the type or category of users or applications it represents.

  • Option 16: Option 16 is also known as the Vendor ID option and it is used by a DHCPv6 a client to identify the vendor that manufactured the hardware on which the client is running.

  • Option 23: Option 23 is also known as the Domain name Server (DNS) option provides a list of one or more IPv6 addresses of DNS recursive name servers to which a client's DNS resolver can send DNS queries.

  • Option 24: Option 24 is also known as the Domain List option and it specifies the domain search list that the client uses to resolve hostnames with the DNS.

• DHCP Timers: This option is used to set different timer value for DHCP client configurations. The various DHCP timer options are:

  • Release-timeout: It is used to set retransmission timeout value for the initial release message.

  • Req-max-rt: It is used to set the maximum retransmission timeout value for the request message.

  • Req-max-rt: It is used to set the maximum retransmission timeout value for the request message.

  • Sol-max-delay: It is used to set the maximum delay time of the first solicit message.

  • Sol-max-rt: It is used to set the maximum solicit retransmission time.

  • Sol-time-out: It is used to set the intial timeout value of the solicit message.

To enable DHCP client on the management Ethernet interface, use the following command:

configure

You can configure the TTI sent or expected string in the full ASCII format, or Source Access Point Identifier (SAPI)/Destination Access Point Identifier (DAPI) format on OTU, ODU, ODU-flex, ODUCn, and coherentDSP controllers for the OTN-XP card.

From R7.3.1 onwards, coherentDSP controller supports only the full ASCII string format.

From R7.3.2 onwards, coherentDSP controller supports SAPI/DAPI string format in addition to the full ASCII string format.

You can configure TTI for the following muxponder modes:

• 10G-Grey-MXP

• 4x100G-MXP-400G-TXP

The following table lists the ASCII format that is supported on each muxponder mode for TTI:

To configure TTI, use the following commands:

configure

controller controller-type R/S/I/P tti {sent | expected} {ascii | sapi ascii | dapi ascii | operator-specific ascii } tti-string

commit

Note	We recommend that you configure TTI in the SAPI/DAPI ASCII format.

The secondary admin state of the coherentDSP or ODU4 controller must be set to maintenance before enabling PRBS.

To enable the PRBS on the trunk port, use the following configuration command at the coherentDSP controller:

controller coherentDSP R/S/I/P prbs mode {source | sink | source-sink} pattern {pn31 | pn23 | pn15 | pn7}

To enable the PRBS on the trunk port, use the following configuration command at the ODU4 controller:

controller odu4 R/S/I/P/L opu prbs mode {source | sink | source-sink} pattern {pn31 | pn23 | pn15 | pn7}

When the PRBS is enabled on the trunk ports, you can view the following impacts in the corresponding client ports:

• Client traffic is dropped in the direction of source to sink as the frames are overwritten by the PRBS pattern.

• Remote fault is raised on the client ports nearer to the PRBS sink.

The following are the ODU4 PRBS combinations. The client ports must have physical loop back in all the combinations.

• Near End client and Near End trunk ODU4

• Near End client and Far End client ODU4

• Near End client and Far End trunk ODU4

• Near End trunk and Far End trunk ODU4

The following sample diagram describes the ODU4 PRBS combination for Near End client and Near End trunk.

You can monitor the status of Pseudo Random Binary Sequence (PRBS) on the CoherentDSP or ODU4 controller using the following command:

show controllers coherentDSP | ODU4 R/S/I/P prbs-details

To configure PBRS mode on the ODU2e controller, you must configure Optical Channel Payload Unit (OPU) on the ODU2e controller followed by the PRBS mode and the pattern. The PRBS supported pattern on the OTN-XP card is invertedPN31.

From R7.3.1 onwards, you can configure PRBS on client or mapper ODU4 and ODU flex controllers.

For fiber channel controllers, PRBS is supported on mapper ODU flex controllers.

Note	ODU2e PRBS is not supported for OTU2E client rates.

To configure PRBS mode on the ODU2e controller, enter the following commands:

configure

controller odu2e | oduflex R/S/I/P/client-port/lane-number

secondary-admin-state maintenance

opu

prbs mode {source | sink | source-sink} pattern invertedpn31 {direction {system | line}}

end

By default, the value of flexo parameters for the coherentDSP controllers in the 400G inverse muxponder, are as follows:

• CoherentDSP 0/0/0/12―GID is 1 and IID is 1, 2.

• CoherentDSP 0/0/0/13―GID is 1 IID is 3, 4.

The following example displays the default configurations on the transmission side:

For 400G inverse muxponder, the flexo configuration on these coherent DSP controllers must be such that GID is the same on coherentDSP controllers on both port 12 and port 13, and IIDs are in the incremental order. In case if one of the node configurations is invalid, the Provisioning Failed alarm is raised on that particular controller. The Provisioning Failed alarm moves to the slice level in case you perform a line card reload.

The following sample configures the same IID on the coherentDSP 0/0/0/12 as that of coherentDSP 0/0/0/13 and shows the resulting Provisioning Failed alarm.
