Description

Getting continuous error log messages on MPC10E

Dec 11 10:19:47 MXrouter fpc3 user.err packetio: [Error] SAMPLER:PKT: Failed to parse UDP header

Dec 11 10:21:54 MXrouter fpc3 user.err packetio: [Error] SAMPLER:PKT: Failed to parse UDP header

Dec 11 10:25:00 MXrouter fpc3 user.err packetio: [Error] SAMPLER:PKT: Failed to parse UDP header

Solution

The messages are sampling errors about being unable to parse a UDP header. 

Could be seen due to invalid packet receipt for sampling on the sampler module. Therefore, the messages are expected error debugs upon receiving these invalid packets and would not have any impact.

This can be ignore and prevented from been written on syslog. Check below for instructions on this
