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!

URGENT - QOS and HP 1800-24G

Asked by leegclystvale in Networking Protocols, Network Switches & Hubs

Tags: HP1800, QOS, 802.1p, traffic prioritisation

Hi,

I have no experience with switches or QOS and have had a lot of HP1800-24G switches deployed across the network. The switch guys say that the switch doesn't support QOS as the manual doesn't mention it, but I can see from the HP1800 FAQS that it states:

Q: How does the ProCurve Switch 1800 series service 802.1p priorities?
A: There is no software configuration of 802.1p for the ProCurve Switch 1800 series. The ProCurve Switch 1800 series honors priorities of the frames received.

Q: How many queues are supported by the ProCurve Switch 1800 series?
A: The ProCurve Switch 1800 series supports 4 queues per port.

Q: How are the 802.1p priorities mapped to the queues for the ProCurve Switch 1800 series?
A: The ProCurve Switch 1800 series 802.1p priorities are mapped as shown in the following table.

Port Queue and 802.1p Priority Values  |           Priority for Exiting From the Port
______________________________________________________________
Low (1 - 2)                                              |           First
Normal (0, 3)                                           |          Second
Medium (4 - 5)                                         |          Thrid
High (6 - 7)                                              |             Fourth


So what does this mean?
The switch will identify voice traffic and allocate it to the highest priority automatically?
How does this work when a VOIP handset is used as a hub with a PC on the end of it?

Really stressed and could do with a good explanation as need to see how voice will be dealt with before it all falls around me!!!

Thanks for any help
