NAME

6       esi - get or set the end system identifier (ESI)
7

SYNOPSIS

9       esi [itf]
10       esi [-f] esi [itf]
11       esi -V
12

DESCRIPTION

14       esi  is  used  to  show or set the end system identifier (ESI, a unique
15       six-byte number corresponding to the MAC address  of  LAN  technologies
16       like  Ethernet)  of  an  ATM  interface. If the interface number itf is
17       omitted, interface 0 is used by default. The esi argument is  a  string
18       of twelve hex digits.
19
20       Only  the ESI stored in the kernel is accessed; esi does not change the
21       ESI stored on the NIC. If a non-zero ESI is already set  on  an  inter‐
22       face, the -f option has to be used to overwrite it.
23
24       Note  that  ESI changes are not automatically propagated throughout the
25       system, e.g. to ilmid. esi should therefore be used early during system
26       initialization.
27

OPTIONS

29       -f     force overwriting an existing ESI.
30
31       -V     print version number of esi on standard output and exit.
