R: Juniper MX960 Mqchip packet lenght error

Thx David,

PR587266 seems to be related to "maximum-packet-lenght" command that is not present in my config.

Biggest problem in this case are dropped packet on interface:

I'm wondering if is something related to CoS that is managed in different way from the two type of linecard.

Hi,

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

Hi all,

After upgrading Juniper MX960 from 4x10Gbe DPCE to 16x10Gbe MPC, I see strange 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.
