isr debug platform packet

[DraganSkundric87318]

hi,

is it possible to get some more detail about tcp packet during debug platform traces? Like length of packet or even sequence numbers?

Hi

 It depends on the device. You can generate a pcap file and run in Wireshark for easy viewing.

i do not need pcap, I need packet lengths or sequence numbers  in "show platform packet all" output

[MHM Cisco World]

debug ip tcp packet <- give you SYN ACK
debug ip tcp ha <- give you length 
give more detail about TCP traffic.

monitor capture on interface of receiving router (isr) shows OOO packets and monitor capture on interface of sending router shows no OOO packets. So I want to do platform debug packet trace and see if it will show OOO packets. But I need lengths or sequences to be shown so I could identify packets and verify order

Can you provide how it is configured, sample example output for us to understand the issue here.

[DraganSkundric87318]

Debug plat cond ipv4 access-list ACL both
Debug plat packet packet 1024 fia-trace

and in trace results I do not see anything I could use to pinpoint packets, beside src/dst ports

there are some sample outputs where tcp sequences are visible, but I cannot get this to work 

this is sample output from documentation

there is some commend need before the show display the TCP packet 
please see below slide.
