Some time ago I had a case with damaged file system on Huawei S5300 switch. It had been caused by power failure on one site. The switch was not able to decompress VRP software and rebooted itself all the time.

As you know, configuring management services on Huawei devices, you can add source interface or IP address for transmitting packets. This is an optional configuration. Below you can find configuration syntax for source interfaces in management communication. If you find out that anything else should be added to this list, just let me know.

As I am in the process of upgrading Huawei ATN950B routers, I decided to describe very useful command, supported by carrier class routers like NE40E, CX600 and ATN950B – “upgrade rollback enable rollback-timer time”
When you are doing upgrade, there is always a small risk that something goes wrong and you will lose this router, I mean it will fall out of management. To minimize such risk, you can use the command in question.
Let’s look at the upgrade procedure:
<labnario>startup system-software v200r002c00spc300.cc Info: Succeeded in setting the software for booting system. <labnario>startup system-software v200r002c00spc300.cc slave-board Info: Succeeded in setting the software for booting system. <labnario>startup patch v200r002sph008.pat Info: Succeeded in setting main board resource file for system. <labnario>startup patch v200r002sph008.pat slave-board Info: Succeeded in setting slave board resource file for system.
Let’s look at a typical configuration of HWTACACS server on Huawei device:

A new version of Huawei network simulation platform has been released. The new eNSP supports AC6605 POE feature. Besides that a few bugs have been solved, among other firewall crashed (often reported) problem when running on Win8 and Win8.1.
