Mtest - CyberData 010878 Operation Manual

C.4 Mtest
The mtest directory contains a small program for testing the multicast membership sockopts and
ioctls. It accepts the following commands, interactively:
j g.g.g.g i.i.i.i
l g.g.g.g i.i.i.i
a ifname e.e.e.e.e.e - add ether multicast address
d ifname e.e.e.e.e.e - del ether multicast address
m ifname 1/0
p ifname 1/0
q
where g.g.g.g
i.i.i.i
ifname
e.e.e.e.e.e is an Ethernet address in hex, e.g., 1.0.5e.0.2.1
1/0
The "p" command to change the promiscuous flag does not work under SunOS, because it uses a
different ioctl for that purpose.
Mtest is useful for establishing targets for multicast ping testing. The results of mtest filter
manipulation can be seen by using the "netstat -nia" command (see next section).
