Upgrading WLC software using CLI

I am trying to make more WLC configuration using CLI. This is the first topic that I want to cover and maybe in future more will come. Now to the steps…

 

  1. Verify the current software version using the command #show sysinfo

Editing Network Interface Configuration in Linux using “vi”

This is a small note for my personal needs. Maybe it will be helpful also to other people.

Displaying interface configuration:

root@ifconfig

Network interface configuration edit:

root@sudo vi /etc/network/interfaces

– vi editing commands:
 i – inserting text in the configuration (from my point of view it is editing) – to end editing “Esc”
 :w – save your configuration
:q – quit if you havent made any changes

– after the changes has been made in interface configuration a restart of networking services is needed

root@sudo /etc/init.d/networking restart

GO! GO! GO!

Today I decided to start my CCIE R&S journey. I already purchased the CCIE Routing and Switching Certification Guide one month ago and my Routing TCP/IP Volume 1 arrived five days ago but I was not personally prepared to start. But today I am feeling that I am ready to start the hard work! First I need to make a detailed study plan and be prepared to dedicate a lot of time for my studies. Second I need to collect some tools that can help me in my studies (software for notes, time management software – please leave a comment if you know about some software that could be helpful for me).

And last but definitely not least –  I think that this would be a lot of fun  Wink

If you have any helpful tips for the written studies please leave a comment.

Wish me luck!

Wireless AP configuration – the beginning…

For some time I have a Cisco 1250 wireless access point in my work lab. I have no big experience with the wireless access point configuration and  there were no time to play with it till today.

The Cisco 1250 is a 802.11n dual-band rugged indoor access point. When you decide to buy this type of access point then you need to be aware that it requires a power injector to deliver power using the PoE from the switch or when you dont want to use a power injector then you can use a power supply.

[old] TSHOOT IPv6 configuration

This is a blog post migrated from my testing blog

Tomorrov I will go for my CCNP – I scheduled the last exam from the CCNP track – TSHOOT. During my studies for this exam I configured the TSHOOT topology in my lab. And below is my IPv6 configuration for TSHOOT. It is simple but maybe for someone it would be helpful.

[old] Cisco documentation in EPUB format

This is a blog post migrated from my testing blog

Yesterday I found out from the Etherealmind blog that some documentation on the Cisco site is now available also in *epub format. For example check the “Cisco Nexus 7000 Series NX-OS Layer 2 Switching Configuration Guide”. Below is a screenshot how it is looking…

If you also want to take a look only search on the Cisco website for EPUB. For me it is awesome. Now I can read some documentation also in bus on my Amazon Kindle Cool

[old] ASA QoS explanation and configuration

 This is a blog post migrated from my testing blog

ASA supported QoS features:

Theese are my notes from this document: http://tinyurl.com/3dmo5ao

  • Policing – Policing is a way of ensuring that no traffic exceeds the maximum rate (in bits/second) that you configure, thus ensuring that no one traffic flow or class can take over the entire resource. The excess traffic is dropped.
  • Priority queuing – LLQ priority queuing lets you prioritize certain traffic flows (such as latency-sensitive traffic like voice and video) ahead of other traffic.
  • Traffic shaping – is used to match device and link speeds, thereby controlling packet loss, variable delay, and link saturation, which can cause jitter and delay. (not supported on ASA 5580)

CUE installation problem?

Today a had some hard time installing the Cisco Unity Express 7.0.6 on an AIM module in a Cisco 2851 router. According the Cisco documentation this should be an easy process for maximum one hour. But for me it was twice the time.

My CUE installation steps:

1. Download the CUE software from the Cisco website. This was simple. I downloaded the cue-vm-k9.nm-aim.7.0.6.zip which I extracted. In the archive there were these files:

  • cue-installer.nm-aim.7.0.6
  • cue-vm-full-k9.nm-aim.7.0.6.prt1
  • cue-vm-installer-k9.nm-aim.7.0.6.prt1
  • cue-vm-k9.nm-aim.7.0.6.pkg
  • cue-vm-langpack.nm-aim.7.0.6.pkg (more…)
