The problem is that i can't figure out what is causing this problem. All ports affected is in the same VLAN.

Re: High collision or drop rate on HP 5300

I would guess you have some sort of packet storm on that VLAN.

Pick an interface, check the counters. See if the rates go very high. Put a packet sniffer on the LAN, see if you get abnormal traffic.

Hi,

I have allready tryed with a packet sniffer, but as the packets are droped (TX drops) i can't see the the packets with a sniffer (Ethereal). I seems that theese packet storms comes in bursts, but i can't se why and from where.

Hello Jesper,

Sometimes these entries are indicative for incorrect VLAN configuration(s). Check the config on this switch, with special attention to your VLANs and assigned ports.

Goodluck

Hallo Eirram,

There is only default VLAN configured on this switch.

Re: High collision or drop rate on HP 5300

Hi, I also have the same problem problem with my core switches, the core switch 1 freezes and kills one portion of the network and then after reloading the core everything comes up again... it happens weekely or even longer..the core has switches and servers connected to it and the following are the things i get from the logs. can they be related to the issue of the network freezing and causing impact on the other portion of the network?

 

see the log massages that i get.
