Validate and Troubleshoot Installation of Software Packages

Procedure

Step 1	show version Displays the software version and details such as system uptime. Example: `RP/0/RP0/CPU0:ios# show version Mon Nov 22 22:50:09.240 IST Cisco IOS XR Software, Version 7.5.1 Copyright (c) 2013-2021 by Cisco Systems, Inc. Build Information: Built By : xxxxxxxxx Built On : Sun Nov 21 23:25:35 PST 2021 Built Host : iox-lnx-054 Workspace : /auto/srcarchive15/prod/7.5.1/ncs1004/ws Version : 7.5.1 Location : /opt/cisco/XR/packages/ Label : 7.5.1 cisco NCS-1004 () processor System uptime is 2 minutes`
Step 2	show install repository Displays a list of all the installed software packages on NCS 1004. Example: `RP/0/RP0/CPU0:ios# show install repository Wed Oct 13 20:14:15.984 IST 6 package(s) in XR repository: ncs1004-mini-x-7.5.1 ncs1004-mpls-2.0.0.0-r751 ncs1004-k9sec-2.1.0.0-r751.x86_64 ncs1004-xr-7.5.1 ncs1004-mpls-te-rsvp-2.1.0.0-r751`
Step 3	show install active Displays a list of all the installed and active software packages on NCS 1004. The following sample output displays active software packages. Example: `RP/0/RP0/CPU0:ios# show install active Mon Mar 11 07:31:12.302 UTC Wed Oct 13 20:14:15.984 IST Node 0/RP0/CPU0 [RP] Boot Partition: xr_lv19 Active Packages: 5 ncs1004-mini-x-7.5.1 ncs1004-mpls-2.0.0.0-r751 ncs1004-k9sec-2.1.0.0-r751.x86_64 ncs1004-xr-7.5.1 ncs1004-mpls-te-rsvp-2.1.0.0-r751`
Step 4	show install committed Displays a list of all committed software packages on NCS 1004. The committed software packages are the software packages that are booted on an NCS 1004 reload. Committed packages are the packages that are persistent across reloads. If you install and activate a package, it remains active until the next reload. If you commit a package set, all packages in that set remain active across reloads until the package set is replaced with another committed package set. The following sample output displays the committed software packages. Example: `RP/0/RP0/CPU0:ios# show install committed Wed Oct 13 20:14:15.984 IST Node 0/RP0/CPU0 [RP] Boot Partition: xr_lv19 Committed Packages: 5 ncs1004-mini-x-7.5.1 ncs1004-mpls-2.0.0.0-r751 ncs1004-k9sec-2.1.0.0-r751.x86_64 ncs1004-xr-7.5.1 ncs1004-mpls-te-rsvp-2.1.0.0-r751`
Step 5	show install log Displays information on the history of the installation operations. This command provides information about both successful and failed installation operations on NCS 1004. You can also verify a Service Maintenance Update (SMU) installation using this command. Example: `RP/0/RP0/CPU0:ios# show install log 49 detail Wed Dec 9 01:19:18.680 UTC Dec 09 01:19:07 Install operation 49 started by root: install add source tftp://10.105.236.167 ncs1004-k9sec.rpm Dec 09 01:19:08 Action 1: install add action started Dec 09 01:19:08 ERROR! Either file is not proper or error in getting rpm metadata from rpm file Dec 09 01:19:08 ERROR!! failed to complete install add precheck Dec 09 01:19:09 Install operation 49 aborted Dec 09 01:19:10 Ending operation 49` In the above example, either a wrong rpm package is used or the rpm package is corrupted. For failure on install add source, check that the package is correctly named and is available at the location.

What to do next

If the expected active software packages are not displayed, install the packages (if required) and activate the packages using the install activate package_name command.

Troubleshoot the Management Interface

Before you begin

Management interface should be configured.

Procedure

Step 1

show interfaces mgmtEth instance

Displays the management interface configuration.

Example:

RP/0/RP0/CPU0:ios# show interfaces MgmtEth 0/RP0/CPU0/0
Fri Nov 13 19:42:29.716 UTC
MgmtEth0/RP0/CPU0/0 is administratively down, line protocol is administratively down
  Interface state transitions: 0
  Hardware is Management Ethernet, address is badb.adba.d098 (bia badb.adba.d098)
  Internet address is 10.58.227.183/24
  MTU 1514 bytes, BW 100000 Kbit (Max: 100000 Kbit)
     reliability 255/255, txload 0/255, rxload 0/255
  Encapsulation ARPA,
  Full-duplex, 100Mb/s, CX, link type is autonegotiation
  loopback not set,
  ARP type ARPA, ARP timeout 04:00:00
  Last input never, output never
  Last clearing of "show interface" counters never
  5 minute input rate 0 bits/sec, 0 packets/sec
  5 minute output rate 0 bits/sec, 0 packets/sec
     0 packets input, 0 bytes, 0 total input drops
     0 drops for unrecognized upper-level protocol
     Received 0 broadcast packets, 0 multicast packets
              0 runts, 0 giants, 0 throttles, 0 parity
     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
     0 packets output, 0 bytes, 0 total output drops
     Output 0 broadcast packets, 0 multicast packets
     0 output errors, 0 underruns, 0 applique, 0 resets
     0 output buffer failures, 0 output buffers swapped out
     0 carrier transitions

In the above result, the management interface is administratively down. Use the no shut command to enable the management interface.
The following example shows sample output from the show running-config interface mgmtEth command when the management interface is in the no shut state.
```
RP/0/RP0/CPU0:ios#show running-config interface mgmtEth 0/RP0/CPU0/0
Fri Nov 13 19:42:54.368 UTC
interface MgmtEth0/RP0/CPU0/0
 ipv4 address dhcp
!
```

You can also use the show interfaces summary and show interfaces brief commands in the Cisco IOS XR EXEC mode to verify the management interface status.

The following example shows sample output from the show interfaces summary command.

RP/0/RP0/CPU0:ios# show interfaces summary
Wed Mar  4 06:14:52.995 UTC
Interface Type          Total    UP       Down     Admin Down
--------------          -----    --       ----     ----------
ALL TYPES               4        2        0        2
--------------
IFT_ETHERNET            3        1        0        2
IFT_NULL                1        1        0        0

The following example shows sample output from the show interfaces brief command.

RP/0/RP0/CPU0:ios# show interfaces brief

     Mg0/RP0/CPU0/0          up          up    ARPA  1514    1000000
     Mg0/RP0/CPU0/1  admin-down  admin-down    ARPA  1514    1000000
     Mg0/RP0/CPU0/2  admin-down  admin-down    ARPA  1514    1000000

Step 2

When the line protocol is down, you must verify the Layer 3 connectivity. You can perform the following steps.

Check the Ethernet cable connection and physical connectivity of NCS 1004 to get the line protocol up.
Ensure ARP connectivity.
Use the ping command to check reachability and network connectivity on the IP network.
Verify the static IP and default gateway configuration.

What to do next

Upgrade all the FPDs using the upgrade hw-module location all fpd all command in the Cisco IOS XR EXEC mode. After upgrade is completed, the Status column shows RLOAD REQ if the software requires reload.

If Reload is required

If the FPGA location is 0/RP0, use the admin hw-module location 0/RP0 reload command. This command reboots only the CPU. As a result, traffic is not impacted. If the FPGA location is 0/0, use the admin hw-module location all reload command. This command reboots the chassis. As a result, traffic is impacted. After the reload is completed, the new FPGA runs the current version.

Caution

The upgrade of OTNXP LC_DP_MOD_FW and LC_OPT_MOD_FW FPDs affect traffic. Hence, you must perform this upgrade during a maintenance window.

If Firmware Upgrade Fails

If firmware upgrade fails, use the show logging command to view the details and upgrade the firmware again using the above commands.

Note

You can upgrade the firmware version of power modules, only when both the power modules are present and powered on.

Loopback

Table 1. Feature History
Feature Name	Release Information	Description
Configuration Alarms for Loopback	Cisco IOS XR Release 7.8.1	A configuration alarm is now triggered whenever there is a change in the loopback configuration. This alarm helps in improving loopback status monitoring. You can now view the alarm details such as, the configuration time and date, description, severity, and location using the show alarms brief system active command.

You can configure the loopback on the CoherentDSP, FC, OTU, and Ethernet controllers 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.

From R7.8.1, 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.

Note

Internal and line loopbacks are supported on the FC, OTU, and Ethernet controllers whereas only internal loopbacks are supported on the CoherentDSP controllers.

Configuring Loopback on the 1.2T Card

To configure the loopback, use the following commands:

configure

controller controllertype Rack/Slot/Instance/Port

sec-admin-state maintenance

loopback [ line | internal ]

Configuring Loopback on OTN-XP Card

From R7.2.1 onwards, OTN-XP card supports loopback on the OTU2, OTU2e, OTU4, 10GE, and CoherentDSP controllers.

From R7.3.2 onwards, OTN-XP card supports loopback on the 100GE and 400GE controllers.

From R7.5.2 onwards, OTN-XP card supports loopback on the 16G FC and 32G FC controllers.

The CoherentDSP controller supports both line and internal.

To configure the loopback on the controllers, use the following commands:

configure

controller controller type Rack/Slot/Instance/Port/Lane number

sec-admin-state maintenance

loopback [ line | internal ]

commit

The range of Lane number is 1–4.

Restriction

From R7.10.1, OTN-XP card supports loopback on STM64 and OC192 controllers. You must use no sec-admin-state command instead of sec-admin-state normal.

Example 1

The following example shows how an internal loopback is configured on the 10GE controller.

Configuring Loopback on 2-QDD-C Card

From R7.3.1 onwards, 2-QDD-C card supports loopback on the 100 and 400GE controllers.

Note

On applying client-side loopbacks, traffic is looped and does not continue in the 2-QDD-C card. QSFP squelching happens on applying internal loopback.

To configure the loopback on the controllers, use the following commands.

configure

controller controllertype Rack/Slot/Instance/Port/Lanenumber

sec-admin-state maintenance

loopback [ line | internal ]

commit

Example

The following example shows how an internal loopback is configured on a 100GE controller.

When you enable LLDP drop on the client controller ports of the muxponder or muxponder slice, the LLDP frames drop on the ports without forwarding.

Note

LLDP on 400GE is not supported on the OTN-XP card.

Configuring LLDP Drop

You can configure the LLDP drop for a muxponder or muxponder slice. By default, the LLDP drop status is set to False. On enabling the LLDP Drop, the status is set to True.

To configure LLDP drop on a muxponder use the following command:

configure

hw-module location location mxponder drop-lldp

Note

Use the no form of the command to disable LLDP drop.

commit

Limitation

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

Note

By default, LLDP is enabled for NCS 1004. 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.

RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios#hw-module location 0/1 mxponder drop-lldp
RP/0/RP0/CPU0:ios#commit

configure

hw-module location location mxponder-slice slice-number drop-lldp

Note

Use the no form of the command to disable LLDP drop.

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

commit

The following is a sample in which slice 0 client ports are enabled with LLDP drop.


RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#hw-module location 0/1 mxponder-slice 0 drop-lldp
RP/0/RP0/CPU0:ios(config)#commit

Verifying the Status of LLDP Drop

To verify the LLDP drop enabled status, use the following command.

Trail Trace Identifier

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 string only in ASCII string format. When the expected TTI string does not match the received TTI trace string, the controller goes down and the OTUK-TIM alarm is raised. To configure TTI on the coherent DSP controllers, use the following commands:

configure

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

commit

Note

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

The following sample displays how to configure TTI on a coherent DSP controller with the sent and expected strings set to the same ASCII string. The state of the controller is up.

Configure TTI on OTN-XP Card

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:

Table 2. ASCII Format Supported on Each Muxponder Mode
Muxponder Mode	ASCII with Character String	Controller
10G Grey	Full ASCII 64-character	OTU2, OTU2E, OTU4, ODU4, ODU2E (10G mapper)
	SAPI ASCII 15-character	OTU2, OTU2E, OTU4, ODU4, ODU2E (10G mapper)
	DAPI ASCII 15-character	OTU2, OTU2E, OTU4, ODU4, ODU2E (10G mapper)
	Operator-specific ASCII 32-character	OTU2, OTU2E, OTU4, ODU4, ODU2E (10G mapper)
4x100G-MXP-400G-TXP	Full ASCII 64-character	OTU4, coherentDSP, ODUC4, ODU4 (100G mapper), and ODU-FLEX (400G mapper)
	SAPI ASCII 15-character	OTU4, coherentDSP, ODUC4, ODU4 (100G mapper), and ODU-FLEX (400G mapper)
	DAPI ASCII 15-character	OTU4, coherentDSP, ODUC4, ODU4 (100G mapper), and ODU-FLEX (400G mapper)
	Operator-specific ASCII 32-character	OTU4, coherentDSP, ODUC4, ODU4 (100G mapper), and ODU-FLEX (400G mapper)

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.

Restriction

For OC192 and STM 64 payloads, configure both sides for ASCII and hex on mapper ODU2.
For OC192 and STM 64 payloads, do not edit operator specific hex on mapper ODU2. Instead, delete and create the operator specific hex.

The following is a sample configuration on ODU4 controller:

Enable TIM CA on Path Monitoring Layer

You can enable Trace Identifier Mismatch (TIM) consequent action (CA) on the Path Monitoring (PM) layer using the pm-tim-ca command on mapper ODUs for Ethernet controller. The TTI transmit string in the SAPI/DAPI format is not configurable on ODUs that are transparent.

For example, the clients that are supported are ODU4, ODU2, and ODU2E, and lower-order ODUs such as ODU2 or ODU2E.

You can configure pm-tim-ca only on mapper ODUs such as ODU2E (10G mapper), ODU4 (100G mapper), and ODU-FLEX (400G mapper).

To configure pm-tim-ca on mapper ODU in the 4x100G-MXP-400G-TXP muxponder mode, use the following commands

Verify the Performance Monitoring Parameters of Controllers

Performance monitoring (PM) parameters are used by service providers to gather, store, set thresholds for, and report performance data for early detection of problems. The user can retrieve both current and historical PM counters for the various controllers in 10 seconds, 15 minutes and 1 day intervals.

Procedure

show controllers controllertype R/S/I/P { pm { current | history } { 30 sec | 15-min | 24-hour } { optics | ether | fec | otn } linenumber }

The following sample output displays the current performance monitoring parameters of the Optics controller in 15-minute intervals. Client optics have four lanes.

Using SNMP for Troubleshooting

The supported MIBs in NCS 1004 are documented in the SNMP chapter of Configuration Guide for Cisco NCS 1004.

Procedure

Use the following commands in EXEC mode to verify and monitor the SNMP for network monitoring and management.

show snmp — Displays the status of SNMP communications.
show snmp mib access — Displays the counters per OID that indicate the number of times an operation was done on an OID.
show snmp mib access time — Displays the timestamp of the last operation on an OID.
show snmp trace requests — Displays a log of the high level PDU processing trace points.
debug snmp packet — Displays information about every SNMP packet sent or received by NCS 1004.
debug snmp requests — Displays information about every SNMP request made by the SNMP manager.

Using Netconf for Troubleshooting

Netconf provides mechanisms to install, manipulate, and delete the configuration of network devices. The Netconf protocol provides a set of operations to manage device configurations and retrieve device state information.

Use the following commands in EXEC mode to retrieve device state information.

Before you begin

Verify the installation of k9sec package.

Generate the crypto key for SSH using the crypto key generate dsa command.

Note

If you access NCS 1004 after regenerating the crypto key, you must remove the ~/.ssh/known_hosts file as there will be a key mismatch between the host and NCS 1004.

Configure SSH.


RP/0/RP0/CPU0:ios# configure
RP/0/RP0/CPU0(config)# ssh server v2
RP/0/RP0/CPU0(config)# ssh server netconf port 830 
RP/0/RP0/CPU0(config)# ssh server netconf  vrf default

Note

Port 830 is the default Netconf port.

Configure Netconf.


RP/0/RP0/CPU0:ios# configure
RP/0/RP0/CPU0(config)# netconf-yang agent ssh

Procedure

Step 1

show netconf-yang clients

Displays the client details for netconf-yang.

Example:

RP/0/RP0/CPU0:ios# show netconf-yang clients
Fri Nov 26 15:28:50.942 UTC
No active netconf sessions found.

Step 2

show netconf-yang statistics

Displays the statistical details for netconf-yang.

Example:

RP/0/RP0/CPU0:ios# show netconf-yang statistics

Note

In the maintenance mode, all the alarms are suppressed and the show alarms command will not show the alarms details. Use the show controllers controllertype R/S/I/P command to view the client and trunk alarms.

Using Onboard Failure Logging

Onboard Failure Logging (OBFL) collects and stores boot, environmental, and critical hardware data in the nonvolatile flash memory of the CPU controller card. This information is used for troubleshooting, testing, and diagnosis if a failure or other error occurs. This data provides improved accuracy in hardware troubleshooting and root cause isolation analysis. The data collected includes field-replaceable unit (FRU) serial number, OS version, total run time, boot status, temperature and voltage at boot, temperature and voltage history, and other board specific errors.

Procedure

show logging onboard { fmea|inventory | temperature|uptime | voltage}

Displays OBFL data.

Example:

The following example shows the uptime information.

sysadmin-vm:0_RP0# show logging onboard uptime
