elconfig is a tool to display and modify the ATM Forum LAN
Emulation Client configuration. elconfig allows the superuser
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.
