Cisco IOS Hints and Tricks is a personal blog of Ivan Pepelnjak. I try to help anyone aiming to gain in-depth knowledge of advanced networking technologies or Cisco IOS-related implementations, but I’m not sponsored by Cisco or any other of the equipment/software vendors mentioned in my posts.

Please keep in mind that I write the blog and answer your questions entirely in my spare time, so I might not be able to answer lengthy questions (particularly if you send me a complete configuration of several routers) or answer your question in a short time span. However, I’m generally open to short-term consulting engagements; just get in touch with me. Larger jobs are best handled by NIL’s professional services team.

If you have an interesting technical question, have made an unusual observation in your network or have a good story you think I should write about, don’t hesitate a second: send me a message (I have to use a web-based form to limit the spam) or visit my page on Facebook. (After becoming a fan, you could also leave a message there.) If you have a question that you feel is relevant to a larger audience, asking it in the NIL forums might be a better option, as other visitors will benefit from our discussions.

I would also ask you to be fair: if you’re seeking detailed help in designing or implementing your network, you should buy commercial services, not rely on uncle Google or the good will of bloggers and forum visitors on the Internet. I trust that you’re able to judge when your question would cross the line.

Last but not least, there are situations where you might get more qualified help elsewhere:

  • If you have a network-down situation, you should stop googling and contact your supplier’s or vendor’s technical assistance center immediately.
  • If you need troubleshooting assistance, contact your vendor/supplier. NIL can also help you with remote assistance services offered within the NIL Assist framework. NIL Monitor service offers long-term proactive monitoring and assistance.
  • If you need professional design or implementation help, I highly recommend the NIL Consult, NIL Design and NIL Implement professional services.
