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 inter-
       face, 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 sys-
       tem initialization.

OPTIONS
       -f     force overwriting an existing ESI.

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