elconfig is a tool to display and modify the ATM Forum LAN Emulation Client
configuration. 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.
- 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 ATMaddress 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.
- 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 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 `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.
