The atm elconfig command allows one to display and modify
the ATM Forum LAN Emulation Client configuration. atm
elconfig allows the super-user to set the ATM address of
the LAN Emulation Configuration Server (LECS), display the
list of Emulated LANs (ELANs) configured in the LECS for
this host, display the list of ELANs locally configured
along with the membership state of each, and locally
administer ELAN membership.
- show
- The -configured flag is used to display the
name, the ATM addresses of the LE Services,
local ATM addresses of the LEC, specific
ELAN information, and the local network
interface name of each ELAN currently configured
in the system. Since the LE Services'
ATM addresses may be acquired dynamically,
only those addresses that have been
learned will be displayed. In addition, if
connections exist to the LE Services, the
VPI/VCI pairs for each connection are displayed.
Alternatively, a single ELAN's
configuration information may be displayed
by specifying the single argument elan. To
retrieve the ATM address of the current
LECS, the -lecs flag is used. If no
options are given, the name and ATM address
of the LES for each ELAN returned by the
LECS are displayed.
- add
- The add command enables the user to join a
particular ELAN and specify certain configuration
parameters. The -auto flag is used
to instruct the LEC to join the ELAN that
is returned by the LECS. The -if flag maps
elan to the network interface (e.g. el0 ),
providing a mapping between ELAN name and
network interface name. The -les flag
allows the specification of the LES's ATM
address as ATMaddress for joining ELANs
whose configuration information is not
returned by a LECS. The -les flag can be
used only when -manual flag is set in the
`atm elconfig set' command.
- delete
- Used with elan, unjoin the specified ELAN,
terminating connections to both its LES and
BUS and removing the network interface
associated with this ELAN. The -auto flag
is used to delete an Automatic ELAN that
was specified by -auto flag during the add
operation. Used with the -lecs flag,
remove the current LECS from the configuration.
A LECS may be deleted only if no
ELANs are currently configured from that
LECS.
- set -lecs
- If the single argument, ATMaddress is used,
set the ATM address of the LECS to ATMad_dress
and mark this LECS as current. If
another set command is invoked with a different
LECS address, this LECS is now
marked as current. The add and delete commands
may only be applied to ELANs returned
by the current LECS. The -manual flag
places the host in a manual configuration
mode; configuration information will not be
retrieved from the LECS and the addition of
ELANs will require the user to set the LES
address by using -les flag in the `atm
elconfig add' command.
- wait
- The wait command waits until all ELAN
interfaces are ready, or until the number
of seconds specified by maxSeconds have
elapsed, whichever occurs first. If
maxSeconds is not specified, then the
default is 60 seconds. The atm elconfig
wait command should be put in the /etc/rc
file after the last ifconfig command so
that subsequent commands that depend on the
ELAN interfaces do not fail. When the
filer is booted, the ELAN interfaces may
not become ready immediately when ifconfig'ed
because it may take several seconds
for the filer and ATM switch to complete
the initialization required by the UNI signalling,
ILMI, and LANE protocols.
The -unit flag is mandatory if there is more than one
adapter installed.
The interface associated with an ELAN must first be configured
"down" through ifconfig(1) before deleting the
ELAN. If the user attempts to delete an ELAN that is
"up", the message `atm elconfig: ELAN in use' will be displayed.
In takeover mode, the ELAN interface names and unit numbers
are those on the live filer, and in partner mode the
interface names and unit numbers are those on the failed
filer. Only ELANs associated with the live or failed
filer are shown, depending on the current host mode.
