TABLE 5-5 /etc/opt/SUNWconn/atm/laneconfig Entry Descriptions

Field

 

Description

 

 

Interface

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.

ATM

Address

This field is for the 20-byte ATM address. The

 

 

$myaddress 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

 

This field identifies the type of entry. For a complete

 

 

description of the laneconfig flags, see TABLE 5-6.

 

 

 

TABLE 5-6describes the flags used in the /etc/opt/SUNWconn/atm/laneconfig

file.

TABLE 5-6 /etc/opt/SUNWconn/atm/laneconfig Flag Descriptions

FlagDescription

lThis 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).

tThis 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 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.

nThis 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.

MNotifies 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 M flag, you can set the MTU size to be either 4 Kbytes (4528 bytes) or 9 Kbytes (9218 bytes).
