The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

How to persistently set a different subnet mask on different interfaces on 2.6

Asked by rwatters in Sun Solaris

Tags: solaris, subnet, how, mask, different

Hey all,

  I have a few 4500's running 2.6 that have multiple NIC's. All of the NICs are on a flat class B network.  Veritas VCS is being added to the boxes and that product requires that it have exclusive control over entire subnets.  Therefore I need to carve off a new class C on two of the interfaces, but don't want to change the masks on the others.  I can change the masks and broadcast settings of two of the interfaces on the fly with ifconfig commands, but a reboot will reset them to the default class B settings.  My question is, what is the correct way to change the settings on these interfaces on Solaris 2.6.  I don't know of a file that has per-interface settings (like Linux does).  I can always make a custom RC script, but that seems a little inelegant. Any advice on the proper way to do this?
