assigning multiple IP addresses to network interface

17 Feb, 2014 How To 0

Why might we want to assign multiple IP addresses to the same interface? The following are the most common scenarios:

hosts in the network segment use IP addresses on different networks
there are not enough host addresses on a logical network segment, suppose a /24 address space and 300 hosts

How to configure multiple IP addresses on Huawei devices?

Let’s configure a pair of routers connected via a Gigabit Ethernet link and use four different logical networks.

[labnarioR1]int gi 0/0/0
[labnarioR1-GigabitEthernet0/0/0]ip add 192.168.12.1 255.255.255.0
[labnarioR1-GigabitEthernet0/0/0]ip add 10.0.12.1 255.255.255.0 sub
[labnarioR1-GigabitEthernet0/0/0]ip add 10.0.22.1 255.255.255.0 sub

indoor and outdoor Huawei ATN905

7 Feb, 2014 General 2

As you know I try to avoid products descriptions here, on this blog. But last time I had possibility to see ATN905 boxes, available in the indoor and outdoor types. You can install them in various environment. The application scenarios of ATN905 are divided into the small-cell base station bearer scenario and the Ethernet demarcation device (EDD) scenario.

Let’s look at the pictures of the two types of this router:

from Huawei CLI – check …

4 Feb, 2014 Command Line 0

Very useful command, especially when you are preparing and executing upgrade of a software of Huawei carrier class devices, like NE40E and CX600. Let’s look what can be checked by this command:

<labnario>check ?
  hardware-compatibility  hardware compatibility
  startup                 Check the version of the resource file
  system-software         system-software
  version                 check version

I personally use “check hardware-compatibility” before all planned upgrades. During a preparation phase of an upgrade, you have to read software release notes, to be sure that all software and hardware components will be compatible with the new software. You can check hardware compatibility by the command, instead of searching software documents.

Imagine that you’ve just uploaded a new software to CFcard of a router. The new software is v600r006c00spc300.

<labnario>check hardware-compatibility v600r006c00spc300.cc

13       FRA200A          Compatible       NA

It’s very simple, isn’t it?

new options in display elabel command

30 Jan, 2014 System Management 0

Some time ago I described how to display electronic labels. As you probably could see, the displayed information looked illegibly, especially for budding engineers.

Starting from V6R6 software of carrier class devices (like Huawei NE40E, CX600), it looks much better. You have all the information at a glance:
