.SH DESCRIPTION
|
|
.B 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 \fIitf\fP is omitted, interface
|
|
0 is used by default. The \fIesi\fP argument is a string of twelve hex digits.
|
|
.P
|
|
Only the ESI stored in the kernel is accessed; \fBesi\fP does not change the
|
|
ESI stored on the NIC. If a non-zero ESI is already set on an interface, the
|
|
\fB\-f\fP option has to be used to overwrite it.
|
|
.P
|
|
Note that ESI changes are not automatically propagated throughout the system,
|
|
e.g. to \fBilmid\fP. \fBesi\fP should therefore be used early during system
|
|
initialization.
|
|
.SH OPTIONS
|
|
.IP \fB\-f\fP
|
|
force overwriting an existing ESI.
|
|
.IP \fB\-V\fP
|
|
print version number of \fBesi\fP on standard output and exit.
