NAME

       esi - get or set the end system identifier (ESI)

SYNOPSIS

       esi [itf]
       esi [-f] esi [itf]
       esi -V

DESCRIPTION

       esi  is  used  to  show  or  set  the end system identifier (ESI, a unique six-byte number
       corresponding to the MAC address of LAN technologies like Ethernet) of an  ATM  interface.
       If  the  interface number itf is omitted, interface 0 is used by default. The esi argument
       is a string of twelve hex digits.

       Only the ESI stored in the kernel is accessed; esi does not change the ESI stored  on  the
       NIC.  If  a  non-zero  ESI is already set on an interface, the -f option has to be used to
       overwrite it.

       Note that ESI changes are not automatically propagated  throughout  the  system,  e.g.  to
       ilmid. esi should therefore be used early during system initialization.

OPTIONS

       -f     force overwriting an existing ESI.

       -V     print version number of esi on standard output and exit.
