S2352 I don‘t know reason of log. Help me, please!

Hello!

I have switch  S2352P-EI Version 5.70 (S2300 V100R005C01SPC100) with patch V100R005SPH016. There is log :"%%01DEFD/4/CPCAR_DROP_MPU(l)[19]:Some packets are dropped by cpcar on the MPU. (Protocol=ttl-expired, Drop-Count=0363)". What could be the reasons of this log?

Tag : S2300,log

you receive packets with TTL field value of 1 . This is the reason of the drops (Protocol=ttl-expired). To find out what packets you need to debug L3 packets. Use debugging ip packet command in user view.
