Thx David,
PR587266 seems to be related to "maximum-packet-lenght" command that is not=

I'm wondering if is something related to CoS that is managed in different w=

Hi,
See the PR587266. Maybe you have Syslog/log statement in a FW filter term.

Objet : Juniper MX960 Mqchip packet lenght error
Hi all,
After upgrading Juniper MX960 from 4x10Gbe DPCE to 16x10Gbe MPC, I see stra=
nge log messages like this:
Fpc10 MQCHIP(0) LI Packet length error, pt entry 22
Seems to be only a "cosmetic" message, but today my team found some traffic=
dropped on interface on this card (before we only request check about log =
message).
Has anyone the same problem?
My software release is Junos 10.3R3.7.
Thanks in advance.
