dear all,

maybe i misunderstand this command. if i drop one interface all others disappear. 
is this what it should do ? ( see below ) 
my environment sun sparc solaris 10 with ntp version 4.2.8p2
my sparc server has 4 nic's. 3 of them are cabled, plumbed and up. no virtual interface 

kind regards
hans
