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.
[labnario]info-center loghost source ? Aux AUX interface Eth-Trunk Ethernet Trunk interface GigabitEthernet GigabitEthernet interface LoopBack LoopBack interface NULL NULL interface Pos POS interface
Radius server source:

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:
# hwtacacs-server template labnario hwtacacs-server authentication 172.16.10.1 hwtacacs-server authorization 172.16.10.1 hwtacacs-server accounting 172.16.10.1 hwtacacs-server source-ip 172.16.10.10 hwtacacs-server shared-key cipher %$%$;XioR#N`7=~][vLDTr2S(2.#%$%$ undo hwtacacs-server user-name domain-included # aaa authentication-scheme hwtacacs authentication-mode hwtacacs local authorization-scheme hwtacacs authorization-mode hwtacacs local accounting-scheme hwtacacs accounting-mode hwtacacs domain default_admin authentication-scheme hwtacacs accounting-scheme hwtacacs authorization-scheme hwtacacs hwtacacs-server labnario local-user labnario password cipher %$%$'3N&Y#>c>Ibb;f:!o4mW(7#h%$%$ local-user labnario privilege level 15 local-user labnario service-type telnet terminal ssh ftp # user-interface vty 0 4 authentication-mode aaa
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.

I spent last week skiing in Polish winter capital – Zakopane. You probably noticed that I didn’t post any new article but weather was wonderful and I had no motivation to turn on my notebook ;).
As plenty of things, after my vacation, keeping me busy, today a short post about command buffer size.
By default the size of the history command buffer is 10. This means that last 10 commands entered by the user can be stored on the memory and repeated using the CLI “↑” key. The range of the command buffer can be tuned and its range is 0 to 256.
