How do i check if the jumbo frames are working because as i said before the mtu size is not set to 9000 on the Vmotion switch and vmk. However when i do
vmkping -s 9000 anotherhostname
or
vmkping -s 9000 VMotionIPaddress of another host
both command seems to be working fine but I was expecting it fail
see output
~ # vmkping p-dc-esx02 -s 9000
PING p-dc-esx02 (10.1.254.88): 9000 data bytes
9008 bytes from 10.1.254.88: icmp_seq=0 ttl=64 time=0.278 ms
9008 bytes from 10.1.254.88: icmp_seq=1 ttl=64 time=0.285 ms
9008 bytes from 10.1.254.88: icmp_seq=2 ttl=64 time=0.507 ms
~ # vmkping -s 9000 10.1.243.5
PING 10.1.243.5 (10.1.243.5): 9000 data bytes
9008 bytes from 10.1.243.5: icmp_seq=0 ttl=64 time=0.338 ms
9008 bytes from 10.1.243.5: icmp_seq=1 ttl=64 time=0.261 ms
9008 bytes from 10.1.243.5: icmp_seq=2 ttl=64 time=0.331 ms
so it seems like the mtu 9000 seems to be working although it is not been set on the dvswitch and vmk. is this correct?
please note: we don't have NFS/ISCSI storage but FC EMC SAN so the above issue is only relating to vMotion
thanks,
