reset saved-configuration

If you need to reconfigure a Huawei device and do not want to delete its configuration line by line, it is the fastest way to restore the device to the default configuration. Reset saved-configuration command does not delete the existing configuration file in storage device. It is required to restart the device to activate changes. Before reboot, the device compares the configuration file to be loaded at the next startup and existing file to be deleted. Finally the device:

• loads the default configuration if both files are the same
• deletes the configuration file in use if they are different
• displays a message indicating that the configuration file does not exist if the configuration file to be deleted does not exist

<labnario> reset saved-configuration
The action will delete the saved configuration in the device.
The configuration will be erased to reconfigure. Continue? [Y/N]: y

Which configuration file is set as the “next startup saved-configuration file” you can check by the following command:

<labnario> display startup
MainBoard:

In this post I will show you how to disable a notification record which appears always after you type a configuration command. This notification causes your frustration when you want to configure anything on this switch and suddenly you see the following record:

[labnario]interface GigabitEthernet 0/0/1
[labnario-GigabitEthernet0/0/1]
Jan  1 2008 00:24:47+01:00 labnario DS/4/DATASYNC_CFGCHANGE:OID 1.3.6.1.4.1.2011.5.25.191.3.1 configurations have been changed. The current change number is 24, the change loop count is 0, and the maximum number of records is 4095.

You have such situation on Huawei S2300, S3300 and S5300 switches if you are logged by the console.

How to cope with it?

You have two ways to do this. The first is to disable it temporarily by the following commands:

<labnario>undo terminal monitor

or

<labnario>undo terminal trapping

The only disadvantage of the temporary solution is that after you are logged by the console once again this notification still exists. At the same time you block all notifications in the console view.

The second solution is to disable this notification in info-center of the switch:

[labnario]info-center source DS channel console trap state off level warning

How to find appropriate parameters for this command?

You can find all needed information from this notification:

Jan  1 2008 00:24:47+01:00 labnario DS/4/DATASYNC_CFGCHANGE:OID 1.3.6.1.4.1.2011.5.25.191.3.1 configurations have been changed. The current change number is 24, the change loop count is 0, and the maximum number of records is 4095.

BFD process-interface-status and process-pst are applicable only for single-hop BFD. Let’s assume that we have two routers directly connected through interface GE1/0/0.

process-interface-status

By associating BFD session status with interface status we can trigger fast route convergence. We can use this function only for BFD session that uses a default multicast IP address to detect the single-hop link. We can use association between BFD session status and interface status in the case, when transport devices exist on the link between the routers. As the actual physical path is segmented by transport devices, the routers on both ends need a long time to detect a fault that occurred on the link. The change of BFD status affects the protocol status of the interface and thus fast convergence is triggered. When the BFD session becomes DOWN, the correspondence interface status also goes to BFD_DOWN state, causing that this direct route is deleted from the routing table but the router can still forward BFD packets.

Remember that BFD should be configured symmetrically on both ends of the link.

Display interface command shows that line protocol state for GE1/0/0 is “BFD status down”:

[Labnario] display interface gigabitethernet 1/0/0
GigabitEthernet1/0/0 current state : UP
Line protocol current state : UP(BFD status down)

You can also associate BFD status with subinterface status by adding the following command:

process-interface-status sub-if

process-pst

As it was mentioned earlier in this post process-pst function is only applicable to single-hop BFD session. BFD can modify Port State Table (PST) when it detects that interface has a fault. It detects that interface is DOWN and modifies the corresponding entry in the PST. Through the PST, upper application protocols can know the BFD detection result. LDP FRR and IP FRR are examples of such protocols that need to know the BFD detection result through PST.

Use the following command in BFD view to permit PST to be modified:

process-pst

I have been describing Huawei datacom devices on my blog since July 2011. I started with some basic information about Huawei CLI, access methods and upgrade procedures. Then I showed you more advanced topics like PBR, DHCP etc. I am pleasantly surprised that this blog is visited by people from all continents, even from countries I have never heard about. As this blog is getting more and more popular I will do my best to publish more interesting posts.

As we went through a some stage, I have decided to prepare a cheat sheet describing Huawei CLI. You can download it as PDF, print and keep it :). I hope it will be useful for you.

What to do if you forgot console password to Huawei S5300 switch?

I received such question last week. One of readers of this blog forgot console password and he wanted to modify startup configuration file from bootrom menu. His operation failed and there was a notification from the system that there is an “invalid package file!” and “auto-booting failed!”.

There was s5300ei-v100r002c02spc100 software installed in this switch so we can focus just on this software.

In S5300 there are two ways to solve this problem:

1. Create configuration file on your PC, upload it to S5300 and modify startup file
2. Delete configuration file from S5300 to let it to boot with empty configuration

Let’s start with the first way:

• Create configuration file on your PC. You can use default empty configuration downloaded from another switch
• Start FTP server on your PC
• Upload the configuration file to flash of S5300 from bootrom menu:
