MCAST(1-NEW)        RISC/os Reference Manual         MCAST(1-NEW)



NAME
     mcast - Add and Delete Multicast Addresses

SYNOPSIS
     /etc/mcast [ -options ] device


DESCRIPTION
     Mcast adds and deletes multicast addresses that the host
     system will accept.  These are ethernet addresses in which
     the first byte is odd.  Note that this does not include
     ff:ff:ff:ff:ff:ff, which is the broadcast address.

OPTIONS
     -a etheraddress
          Adds etheraddress to multicast addresses being
          accepted.

     -d etheraddress
          Deletes etheraddress from multicast addresses being
          accepted.

PARAMETERS
     device
          is the device name that is to be used to add or delete
          address.  Note that the address list is global to all
          interfaces.  Usually, /dev/dlpi is used as the device.

EXAMPLES
     mcast -a 1:2:3:4:5:6 /dev/dlpi
          mcast -d 5:5:5:5:5:5 /dev/dlpi

DIAGNOSTICS
     The error messages are the standard operating system mes-
     sages.
