flowadm isn't capturing local iSCSI traffic. Should it be?
Summary setup:
snv_107 w/ xVM Hypervisor on a Sun Blade X6250, using e1000g0 link
COMSTAR iSCSI target set up locally in dom0, on port 3261
flowadm add-flow -l e1000g0 -a transport=tcp,local_port=3261 -p maxbw=60 iscsi
iSCSI initiator set up locally in dom0
"flowadm show-flow -i 5 -S iscsi" shows no traffic when accessing disk in dom0
"snoop tcp host $host port 3261" shows traffic when accessing disk in dom0
Traffic is correctly captured in a flow when the iSCSI target is on a
remote host and the flow is set up using a remote_ip attribute.
Detailed setup:
