The Automatic-In-Service (AINS) feature allows the controller to automatically move to the automatic-in-service state after the maintenance window is completed. A soak time period is associated with the AINS state. The controller automatically moves to the In-Service state after the soak time period is completed. During the AINS maintenance window, alarms are not propagated to the EMS/NMS monitoring system.

You can configure AINS on the client ports of the 1.2T and 2.4T cards.

Forward Error Correction (FEC) is used for controlling errors during data transmission. This feature can be enabled on 1.2T and 2.4T cards and works by adding data redundancy to the transmitted message using an algorithm. This redundancy allows the receiver to detect and correct a limited number of errors occurring anywhere in the message, instead of having to ask the transmitter to resend the message.

FEC is automatically enabled on the pluggables installed in the Cisco NCS 1014. When you upgrade the software of an NCS 1014 with pluggables in the FEC disabled mode, traffic is affected.

You can enable laser squelching on Ethernet controllers. Laser squelching can be enabled on 1.2T and 2.4T cards which shuts down the laser in the event of trunk faults (LOS, LOF), and a SQUELCHED alarm is raised on the mapped client port.

Laser squelching uses an interrupt based method. Hence squelching happens faster when compared to previous releases. Squelch happens for client alarms also like Ingress LF, LOA, and CSF (not for egress client alarms) in addition to trunk fault cases.

To configure laser squelching on 1.2T card, use the following commands:

configure

controller HundredGigECtrlr Rack/Slot/Instance/Port

laser-squelch

commit

To configure laser squelching on a 2.4T card, use the following commands:

configure

When a fault occurs on the trunk port, you can hold the propagation of local faults using the idle insertion feature. This feature is can be enabled on the ethernet controllers of 1.2T and 2.4T cards by configuring the hold-off timer.

When the fault occurs on the trunk, idles are inserted in the traffic stream from the trunk port to the client port for the duration of the configured holdoff-time. If the trunk port remains faulty beyond the configured holdoff-time, a local fault is transmitted towards the client device. If the trunk recovers from the fault before the holdoff-time expires, traffic resumes.

This feature can be used on customer deployments to prevent reset of client ports during a PSM switchover.

The 2.4T card uses flexible OTN (flexO) interfaces on trunk ports. These flexO interfaces provide a flexible and interoperable mechanism to transport OTU signals by grouping standard lower rate interfaces. Each flexO interface group is identified by a flexO group identification (GID) number, which ranges 1–1,048,576. Each member of a flexO group is identified by a flexO instance identification (IID) number. The IID cannot be changed.

The LLDP can be configured on management interface of 1.2T and 2.4T cards. It requires a system to form LLDP neighborship over the system management interface, through which it advertises and learns LLDP neighbor information. This information about neighbors is used to learn about the neighbors and in turn the topology of the devices for Operations, Administration, and Maintenance (OAM) purposes.

Advantages of LLDP

• Provides support on non-Cisco devices.

• Enables neighbor discovery between non-Cisco devices.

Limitation

• When you disable LLDP globally, the LLDP gets disabled on all the interfaces.

Note	By default, LLDP is enabled for NCS 1014. But when you enable and disable LLDP in the global configuration mode, LLDP gets disabled on all the interfaces. Workaround: You must enable LLDP globally or reload the Router.

Cisco Discovery Protocol (CDP) vs LLDP

The CDP is a device discovery protocol that runs over Layer 2. Layer 2 is also known as the data link layer that runs on all Cisco devices, such as routers, bridges, access servers, and switches. This protocol allows the network management applications to automatically discover and learn about other Cisco devices that connect to the network.

The LLDP is also a device discovery protocol that runs over Layer 2. This protocol allows the network management applications to automatically discover and learn about other non-Cisco devices that connect to the network.

Interoperability between non-Cisco devices using LLDP

LLDP is also a neighbor discovery protocol that is used by network devices to advertise information about themselves to other devices on the network. This protocol runs over the data link layer, which allows two systems running different network layer protocols to learn about each other.

With LLDP, the user can also access the information about a particular physical network connection. If the user uses a non-Cisco monitoring tool (through SNMP), LLDP helps you identify the Object Identifiers (OIDs) that the system supports. The following OIDs are supported:

• 1.0.8802.1.1.2.1.4.1.1.4

• 1.0.8802.1.1.2.1.4.1.1.5

• 1.0.8802.1.1.2.1.4.1.1.6

• 1.0.8802.1.1.2.1.4.1.1.7

• 1.0.8802.1.1.2.1.4.1.1.8

• 1.0.8802.1.1.2.1.4.1.1.9

• 1.0.8802.1.1.2.1.4.1.1.10

• 1.0.8802.1.1.2.1.4.1.1.11

• 1.0.8802.1.1.2.1.4.1.1.12

Neighbor Discovery

System advertises the LLDP TLV (Type Length Value) details over the management network using which other devices in the management network can learn about this device.

Configuring LLDP

• LLDP full stack functionality is supported on all three management interfaces supported in NCS 1014.

• You can selectively enable or disable LLDP on any of the management interfaces on demand.

• You can selectively enable or disable LLDP transmit or receive functionality at the management interface level.

• Information gathered using LLDP can be stored in the device Management Information Database (MIB) and queried with the Simple Network Management protocol (SNMP).

• LLDP operational data are available in both Command Line Interface and netconf-yang interface.

Enabling LLDP Globally

When you enable LLDP globally, all interfaces that support LLDP are automatically enabled for both transmit and receive operations.

Note	You can override this default operation at the interface to disable receive or transmit operations.

The following table describes the global LLDP attributes that the user can configure:

The following example shows the commands to configure LLDP globally. The global LLDP configuration enables LLDP on all the three management interfaces.

RP/0/RP0/CPU0:ios(config-if)#lldp receive disable
RP/0/RP0/CPU0:ios(config-if)#commit

Debugging LLDP Issues

The following commands are used for debugging issues in the LLDP functionality.

• show lldp traffic

• debug lldp all

• debug lldp errors

• debug lldp events

• debug lldp packets

• debug lldp tlvs

• debug lldp trace

• debug lldp verbose

MAC address snooping allows you to learn the MAC address of the neighbor on 1.2T cards, that is connected to the client ports. You can enable ARP snooping on all client ports and learn the MAC address of neighbors through CLI.

This feature overcomes the limitation, where LLDP (Link Layer Discovery protocol) cannot be enabled in some networks.

Limitations

• When you enable or disable MAC address snooping on any slice, few packets are dropped during configuration.

• Open config interface for enabling or disabling MAC address snooping is not supported.

• SNMP MIB is not supported for the MAC address attribute.

Note	When you enable MAC address snooping on client ports, it overrides LLDP.

Transmit shut on trunk optics controller brings down the CIM8 and PICO transmit power. You can configure transmit shut on optics controller of a 1.2T or 2.4T card.

You can configure loopback on the CoherentDSP and Ethernet controllers of QXP, 1.2T and 2.4T cards to identify connection problems. The loopback can be configured only in the maintenance mode. Use the controller controller-type and the secondary-admin-state maintenance commands to place the controllers in the maintenance mode.

Loopback configuration alarm details for each controller are triggered whenever there is a change in the loopback configuration. Details such as, location of the controller, severity, configuration date and time, and description are available in the output of the show alarms brief system active and show alarms brief history commands.

Configuring Loopback on the 1.2T Card

To configure the loopback on a 1.2T card, use the following commands:

controller controllertype Rack/Slot/Instance/Port

sec-admin-state maintenance

loopback [ internal ]

Note	Line loopback is not supported on CoherentDSP controller of 1.2T card.

Note	Perform this operation only on the console port.

You can restore the factory settings on the NCS 1014. The entire system configuration, including usernames, passwords, and IP addresses, is removed. You can perform this operation only through the console port and not on the management interface. To restore NCS 1014 to factory settings, use the commit replace command. After the commit replace operation completes, you must perform the IOS XR reload operation.

The commit best-effort command merges the target configuration with the running configuration and commits only valid changes (best effort). Some configuration changes might fail due to semantic errors.

During process restarts, CPU reload, or removal of CPU, the NCS 1014 operates in headless mode for up to 72 hours. During this time, traffic is not impacted, although the control plane is not up and running. Fault propagation continues to operate for failures on client and trunk ports. However, you cannot provision anything nor view operational data with a non-functional CPU. Performance monitoring data based on 15 minutes and 24 hour intervals is not supported with a non-functional CPU.

The Trail trace identifier (TTI) feature helps you to identify the signal from the source to the destination within the network. You can configure the TTI sent or expected in ASCII and HEX. When the expected TTI string does not match the received TTI trace string, the controller goes down and the TIM alarm is raised. To configure TTI on the coherent DSP controllers of a 1.2T or 2.4T card, use the following commands:

configure

controller coherentDSP R/S/I/P tti {sent | expected} ascii | hextti-string

commit

Note	The tti-string can have a maximum of 64 characters.

You can configure chromatic dispersion on optics controllers of 1.2T and 2.4T cards. When you configure the maximum and minimum values for chromatic dispersion for any data rate, ensure the minimum difference between the configured values is equal to or greater than 1500 ps/nm.

The following table lists the default CD search range for a 1.2T card.

The following table lists the default CD search range for 2.4T cards.

Note	The cd-min and cd-max values must be set for BPS values that are greater than 4 in the 1.2T card.

Note	When the user provisions the cd-min and cd-max values that are outside the range through CLI, the provisioned values are accepted; however, only the actual values supported by the hardware are applied.

The following is a sample where chromatic dispersion is configured on the optics controller.

The Pseudo Random Binary Sequence (PRBS) feature feature enables data integrity checks between NCS1014 trunk and client links without generating client traffic.

To ensure that the traffic is error-free during link bring up without relying on the peer port, you must enable the PRBS feature on both the transmitting and receiving ports of your NCS 1014 trunk. The transmitting trunk port creates a bit pattern and sends it to the peer NCS 1014 device. The device then confirms if the sent bit pattern is received. The 1.2T card supports PRBS on the ODU4 controller.

You can configure PRBS on the NCS 1014 trunk and client ports of a 1.2T and 2.4T cards.

• Source mode — The NCS 1014 at trunk port generates PRBS signal on the line continuously as per the configured PRBS pattern.

• Sink mode — The NCS 1014 at trunk port gets locked to the ingress signal according to the configured pattern, analyzes and reports the errors.

• Source-Sink mode — The NCS 1014 at trunk port acts as both the PRBS transmitter and receiver, that is, it generates PRBS signal as per the configured pattern, and also gets locked to the ingress signal with the same pattern, and reports the errors.

NCS 1014 trunk port supports the following PRBS patterns:

• PRBS31 — Sequence length is from 2^31 -1 bits.

• PRBS23 — Sequence length is from 2^23 -1 bits.

• PRBS15 — Sequence length is from 2^15 -1 bits.

• PRBS11 —Sequence length is from 2^11 -1 bits.

• PRBS7 —Sequence length is from 2^7 -1 bits.

Note	NCS1K4-2.4T-K9 Interoperability for ethernet PRBS PN23 pattern is not supported.

The NCS1K14-CCMD-16-C and NCS1K14-CCMD-16-L cards have two types of controllers. The controllers are OMS and OCH controllers. When the NCS1K14-CCMD-16-C and NCS1K14-CCMD-16-L cards become operational, both the OMS and OCH controllers are automatically created by default.

To view the OCH controllers, run the following command:

RP/0/RP0/CPU0:ios#show controllers och ?

The following output shows the active OCH controllers in Slot 0 from port 1 to 16.
