HP ProCurve 2626 (J4900B) - Packet Loss

Welcome,

I have a problem with 2626 switch. When I plug it in to my network it works for a while then all of nothing all packets to gateway are lost or some part of them. But for the rest of devices all packets go in both ways. CPU utilization is 5%. Network has around 1500 users but at one time around 600 are preset.

GATEWAY яГЯяГа HP 2626 яГЯяГа16 port Switch яГа Rest of network.

Or

GATEWAY яГЯяГа HP 2626 яГЯяГа Rest of network.

My regional branch of HP was so kind that they send me a replacement but the switch was ok and itтАЩs not a hardware problem (at least not in HP 2626).

CommandтАЩs тАЬshow techтАЭ and тАЬshow loggingтАЭ didnтАЩt show any CRC/DUPLEX Alignment problems. Counters show that all is ok and they donтАЩt indicate any packet drop or something related to RX/TX errors.

Everything works and all of sudden gateway тАЬdisappearsтАЭ like network cable was unplugged after few seconds everything goes back to normal.

The best thing is that everything works witch quite cheap switches and packet loss is below 1%, with HP 2626 I get packet loss around 20-30 %.

Any ideas where to star look for problems because IтАЩm starting to run out of ideas.

Thanks and Regards,
Robert.

Hi Robert,

What version of software are you running on the device?

Are there any known issues that have since been addressed in a later release?

Cheers
