cause study for discarded packets
Hi,
according to IMC I have discarded packets (0.00% to several 1. 2. 3. ... %, so also "orange" alerts) on nearly all of my switches. It doesn´t depend on the configuration at all, i.e. 10Gbe/1Gbe, trunk, hybrid, LACP,... it doesn´t matter. Well, when I look at the counters for those interfaces within the CLI on the switch itself, I actually do not see any packets within the counters that would match.
So what is the reason?
- Do I have overload situations? I don´t think so
- Some QOS issue? Why should the packets been dropped if the links are way no saturated...
- micro bursts? According to IMC those discarded packets are also on my 10Gbe links with barely traffic
- buffer problems? Should I enable "burst-control enable" on all switches and problems are gone?
- hardware problems? Well those switches are A5500-EI, A5500-HI, A5800 IMC sees errors everywhere.
- What counters does IMC read at all?
- Is there any possibility to debug it?
Regards,

Re: cause study for discarded packets
So, I´ve never solved that problem and I´m still getting those "errors". Perhaps someone knows more nowadays?
