from Huawei CLI – check …

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

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:

why does subinterface fail to forward packets

Let’s imagine that we have a simple topology like below:

arp-topology

Configure subinterfaces on both AR routers for VLAN tag termination:

[R1]interface GigabitEthernet 0/0/0.100
[R1-GigabitEthernet0/0/0.100]ip address 10.0.0.1 24
[R1-GigabitEthernet0/0/0.100]dot1q termination vid 100

[R2]int GigabitEthernet 0/0/0.100
[R2-GigabitEthernet0/0/0.100]ip address 10.0.0.2 24
[R2-GigabitEthernet0/0/0.100]dot1q termination vid 100

Try to ping IP address of neighboring router:

[R1]ping 10.0.0.2
  PING 10.0.0.2: 56  data bytes, press CTRL_C to break
    Request time out
    Request time out
    Request time out

Huawei eNSP – news

And we have 2014 …

I hope you are doing well.

First of all, I’d like to thank you for your comments and suggestions. Not always I have time to respond for all your emails or comments but believe that all are appreciated. I maintain this blog after work but having 2 small absorbing children, it is not easy to reply for all your emails or even prepare a new post. I’ll do my best to publish new interesting and informative articles in the new year.

I believe that this year will be better for all of us.

So, let’s start 2014 with a new Huawei eNSP release:
