Backup of log files

Download the log files in the CF card to the local device as a backup through FTP or TFTP.

The CF card must store the log files in a certain period.

PAF and license files

Run the dir and display startup command.

The filenames, size, creation time, contents of the PAF and license files should meet the requirements.

The bolded information as shown in the following output means the name of PAF and license files are identical.

Patch

Run the dir and display patch-information commands.

The patch files in the CF card should meet the requirements and in running state.

Interface configuration

Run the display interface or display current-configuration command.

  • The interface that is in the Down state cannot have configuration but the shutdown command.
  • The interfaces that are in the Up state must have configurations.
  • If the interface is not in service, use the shutdown command to set it in the administratively Down state.

Interface description

Run the display interface command.

All the activated interfaces should be described in accordance to a certain rule.

If there is no relevant rule, abide by the following rule: local device name/local port number/remote device name/remote port number/remote port rate.

Active/standby switchover status

Run the display switchover state command.

When the software and hardware of the device run normally and the AMB/SMB switchover can be performed, the ReadyForSwitch is true.

[~HUAWEI]display switchover state
   Switchover State  :  Ready
   Switchover Policy :  Board Switchover
   MainBoard         :  11
   SlaveBoard        :  12
   ...... 

Startup files

Run the display startup command.

The startup files of the active and the standby boards should be identical.

The bolded information is shown in the following output.

Cleanness and tidiness

Examine the device surface, the components inside the device, the air filters, floors, and the tabletop.

  • They should be clean and tidy.
  • Clean and replace the air filter in time to ensure ventilation and heat dissipation of the cabinet and the fan frames.

Heat dissipation

Examine the heat dissipation of the device.

  • The fans must be kept running when the device is working. Do not switch off the fans at random unless you clean the device.
  • Keep the vent of the device uncovered.
  • Clean the air filters periodically.

Power supply backup

Check whether there is a redundant power module for backup.

  • It is recommended to install a backup power supply module. Both the two power supply modules should be on.
  • If there is no backup, record this issue.

Software versions of the system and boards

Run the display version command.

The software versions of the system and boards must meet the requirements.

The versions of the active and standby boards must be identical.

Cable layout

Examine the cable layout.

Power cables and service cables must be laid out separately.

The cables must be laid out in order.

Cable labels

Examine the cable labels.

The cable labels must be clear, accurate, and in compliance with the related standard.

For details, refer to the appendix in the Installation Guide.

Surface of the frame

Examine the surface of the frame.

The surface must be in good condition.

Idle slots must be installed with a filler panel.

Heat dissipation of the frame

Examine heat dissipation of the frame.

The frame vent should be clean, and heat dissipation of the device should be normal.

Redundancy configuration

Run the display current-configuration command.

All the configurations must be useful. Cancel the unnecessary configurations.

Interface clock

Run the display interface command.

Only 10GE WAN interfaces need clock configuration.

  • When two routers are connected back-to-back, the master clock mode should be set for both of them or one should be set as the master clock and the other should be set as the slave clock.

  • If the WDM system is used between the routers, the routers should be set in the master clock mode.

  • If the active SDH or SONET system is used between the routers, the routers should be set in the slave clock mode.

  • Set the clock mode only on the PPP enabled interfaces.

  • The routing entries should be summarized through CIDR.

  • Do not create unnecessary routes and redundant routes.

BGP route

Run the display bgp routing-table command.

Use network+black hole route to manually perform route aggregation, and then advertise the aggregated route statistically.

It is recommended that you configure the router to advertise routes by using network.

You can also configure the router to import routes by using the import command.

OSPF router ID

Run the display current-configuration configuration ospf or the display router id command.

  • The router ID should use the address of the loopback interface.

  • If the loopback interface is not assigned an IP address, use the IP address of the incoming interface or the IP address of an interface least to be down.

OSPF route

Run the display ospf routing command.

It is recommended that you configure the router to advertise routes by using network.

You can also configure the router to import routes by using the import command.

OSPF STUB area

Run the display current-configuration configuration ospf command.

Stub area is not allowed to import external routes

OSPF error packets

Run the display ospf error command and after five minutes, run this command again. Collect the number of error packets for comparison.

The number of error packets should not increase.

Consistency of OSPF router ID

Run the display router id or display ospf brief command.

The router ID should be identical with the OSPF process ID.

IS-IS system ID

Run the display router id command.

  • The system ID is an extension of the loopback interface address.

  • If no loopback interface address is assigned, use the IP address of the incoming interface.

IS-IS route

Run the display isis route command.

It is recommended that you configure the router to advertise routes by using network.

You can also configure the router to import routes by using the import command.

ISIS wide-metric

Run the display current-configuration configuration isis command.

The cost style parameter of IS-IS is narrow, wide, wide-compatible, compatible, narrow-compatible.

IS-IS address

Run the display current-configurationconfiguration isis command.

The network entity can have only one address.

Usually, one router can be configured with three areas at most.

MPLS LSR-ID

Run the display current-configuration | include mpls lsr-id command.

  • The LSR-ID should use the loopback address. The LSR-ID must be unique in the backbone network.

  • If the loopback interface is not assigned an IP address, use the IP address of the incoming interface or the IP address of an interface least to be down.

MPLS LDP peer status

Run the display mpls ldp peer command.

There is information about LDP peer.

Fire control

Check the key parts such as the cabinet, frame, and cable trough.

All parts must be fire-proof. All fire prevention facilities must be in good condition.

Theft prevention

Check doors, windows, and theft-proof nets of the equipment room.

They must be in good condition.
