These probes trace packets on physical interfaces and also packets on loopback interfaces that are processed by ip
. An IP packet must have a full IP header to be visible by these probes.
Note:
Loopbacktcp
packets on Oracle Solaris may be processed by tcp
fusion, a performance feature that by-passes the ip
layer. These fused packets will not be visible using the ip:::send
and ip:::receive
probes. They are typically all loopback tcp
packets after the tcp
handshake.
