ESI(8) Maintenance Commands ESI(8)
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.
