Hi guys,
I am in trouble with x86_64 Fedora 13 that having tcp/icmp error checksum on
fast-ethernet ports of sun quad-ethernet.
My lab is based on dynamips that having router ethernet ports connected to
linux_eth that binding to sun quadether fast-ethernet that in turn connected to
3550/3560 sw.
ICMP/TCP packets from dynamips router to sw always having checksum failure that
lead to ICMP timeout or TCP session not able to establish but CDP/DTP is ok. By
showing cdp neighbor on dynamips routers & sw, they are detected each other.
Just want to know if anyone having same issue and may be helpful to me as your
advises are always appreciated.
Cheers,
Phuc
