Verifying the upgrade

This chapter includes the following sections:

·     Verifying that the router is running the new BootWare image

·     Verifying that the router is running the new software images

·     Verifying that a patch or feature image is installed successfully

·     Verifying that the cards and subcards are in normal state (modular router)

·     Verifying that the router is in stable state

·     Verifying that the configuration has been recovered

·     Verifying that the services are normal

Verifying that the router is running the new BootWare image

	NOTE: The verification is required only if the BootWare image has been upgraded.

 

Use one of the following methods:

·     Reboot the router to check whether the router is running the new BootWare image.

If not, examine the upgrade steps and perform the upgrade steps again.

The command output might vary by router model. This section uses a CR16000-F router as an example.

·     Use the display version command to verify that the router is running the new BootWare image. If not, examine the upgrade steps and perform the upgrade steps again.

Verifying that the router is running the new software images

	NOTE: The verification is required only if the startup software has been upgraded.

 

# Use the display boot-loader command to check whether the router is running the new software images.

If not, examine the upgrade steps and perform the upgrade steps again.

The command output might vary by router model. This section uses a CR16000-F router as an example.

<Sysname>display boot-loader

Software images on slot 0:

Current software images:

  cfa0:/CR16000-CMW710-BOOT-R8260P22.bin

  cfa0:/CR16000-CMW710-SYSTEM-R8260P22.bin

Main startup software images:

  cfa0:/CR16000-CMW710-BOOT-R8260P22.bin

  cfa0:/CR16000-CMW710-SYSTEM-R8260P22.bin

Backup startup software images:

  None

Verifying that a patch or feature image is installed successfully

	NOTE: The verification is required only if a patch or feature image has been installed.

 

# Use the display install active command to check whether a patch or feature image has been installed successfully.

If the command output does not have a patch or feature image, no patch or feature image has been installed or the patch or feature image installation fails.

The command output might vary by router model. This section uses a CR16000-F router as an example.

<Sysname>display install active

Active packages on slot 0:

  cfa0:/CR16000-CMW710-BOOT-R8260P22.bin

  cfa0:/CR16000-CMW710-SYSTEM-R8260P22.bin

  cfa0:/CR16000-CMW710-SYSTEM-WEAK-R8260P22H01.bin

Active packages on slot 6:

  cfa0:/CR16000-CMW710-BOOT-R8260P22.bin

  cfa0:/CR16000-CMW710-SYSTEM-R8260P22.bin

  cfa0:/CR16000-CMW710-SYSTEM-WEAK-R8260P22H01.bin

Active packages on slot 13:

  cfa0:/CR16000-CMW710-BOOT-R8260P22.bin

  cfa0:/CR16000-CMW710-SYSTEM-R8260P22.bin

  cfa0:/CR16000-CMW710-SYSTEM-WEAK-R8260P22H01.bin

Verifying that the cards and subcards are in normal state (modular router)

# Use the display device command to check whether the cards and subcards are in normal state.

The Brd Status field indicates the card or subcard status.

The command output might vary by router model. This section uses a CR16000-F router as an example.

Verifying that the router is in stable state

# Use the display system stable state command to check whether the router is in stable state.

The router is stable if the System State field displays Stable.

The command output might vary by router model. This section uses a CR16000-F router as an example.

<Sysname> display system stable state

System state     : Stable

Redundancy state : No redundancy

  Slot    CPU    Role       State

  0       0      Active     Stable

  6       0      Other      Stable

  6       1      Other      Stable

  13      0      Other      Stable

Verifying that the configuration has been recovered

# Use the display current-configuration command to view the current configuration.

# Use the display diff current-configuration startup-configuration command to check whether configurations are lost or modified.

Verifying that the services are normal

# Collect entries (such as routing entries, FIB entries, and MAC address entries) and compare them with the entries before the upgrade to check whether entries are lost.

# Check whether the service traffic before and after the upgrade is the same.

# Check whether the servers such as NMS servers are working correctly.

 

	NOTE: Before verifying the services, do not execute the save command.
