ace
Refers to the LAN Emulation interface, laneN.
MAC Address/ELAN Name
This field is for the 6-byte MAC address of the
interface, or, in the case of an n entry, the name of the
emulated LAN to join.
interface, or, in the case of an n entry, the name of the
emulated LAN to join.
ATM Address
This field is for the 20-byte ATM address. The
$myaddres
s variable assigns the local switch prefix,
local MAC address, and default selector.
VCI
The VCI field is a positive decimal integer identifying
a Permanent Virtual Circuit. Place a dash in this field if
VCI is not used.

Flag Descriptions
Flag
Description
l
This flag designates a local address entry. There must be a
l
entry for each
interface running LAN Emulation. The interface and the ATM address must be
included; the MAC address may be included (default is the MAC address
assigned to the board).
included; the MAC address may be included (default is the MAC address
assigned to the board).
t
This flag designates a table entry for the local MAC-ATM address resolution
table. If you want to avoid the address resolution process for a frequently
accessed system, for instance, you may include a
table. If you want to avoid the address resolution process for a frequently
accessed system, for instance, you may include a
t
entry for that system; you
may also create PVCs with a
t
entry. The interface, MAC address, and either
ATM address or VCI (for SVC or PVC connection, respectively) must be
included.
included.
n
This flag allows you to specify the name of an emulated LAN to join. By default,
the SunATM implementation will use the name provided by the LECS. If you
want to specify a different name, or if your LECS requires that a user include a
name in its requests, a name may be provided with this flag. Interface is
required; the name should be entered in the second field.

M
Notifies the system that a larger MTU size will be used in the ELAN that this
lane instance will join. The default MTU size is 1500 bytes. With the
