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!

"Excessive CRC/Alignment Errors" on HP ProCurve 2810-48G

Asked by DavidOHaycox in Networking Cables, Network Cards & Adapters, Network Switches & Hubs

Tags: , , ,

We recently installed a ProCurve 2810-48G switch - it's pretty much on default settings, here's the config:

; J9022A Configuration Editor; Created on release #N.10.02

hostname "ProCurve Switch 2810-48G"
snmp-server community "public" Unrestricted
vlan 1
   name "DEFAULT_VLAN"
   untagged 1-48
   ip address dhcp-bootp
   exit

We're using 47 of the 49 ports at a mixture of 100Mb and 1Gb speeds.  "Log Network Problems" is set to medium sensitivity.

The switch is showing a number of errors in the alert log. Six ports (always the same ones) show "Excessive CRC / Alignment errors" intermittently, including, but not limited to, times when the PC on that port was booted up.  The ports with errors are all connected to PCs with gigabit NICs, of a couple of different types, running XP Pro.

Also we have two ports showing "Excessive Broadcasts" - one of these is a server that was rebooted at the time of the event being logged, the other is a PC running Vista 64-bit.

Cabling and patch leads are all CAT5e, although it's not been certified by means of a Fluke or other device - only by a continuity tester (i.e. we know all pairs are correctly wired for each cable, but that is all).

Is this anything to worry about?  Does it even need addressing, as everything appears to work correctly?

Thanks in advance for any help.Start Free Trial
