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.
