Correct; the system doesn't allow you to do that. It won't let you set the MTU greater than ill_max_frag, which is hard-coded to IP_LOOPBACK_MTU (8192) for lo0. How have you determined that the default MTU setting on the lo0 interface is in fact the problem in this instance? > Its on T2000, solaris 10, patch level 120011-14. Solaris 10 isn't OpenSolaris.

'e1000g' is an Ethernet driver. It has nothing to do with loopback. -- James Carlson, Solaris Networking <[EMAIL PROTECTED]> Sun Microsystems / 35 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677 _______________________________________________ networking-discuss mailing list [email protected]
