Chapter 5 Editing SunATM Configuration Files 55

TABLE 5-7 describes the required, optional, and illegal fields for each flag type.

a Represents an address that may have access to this host. If no a entries appear

in the laneconfig file, access to the host is unrestricted. Including a entries

allows access to be restricted to known hosts. As an alternative to listing

individual addresses, the ATM address field may contain a prefix, followed by

the wildcard $anymacsel, which matches any 7-byte ESI/Selector combination

following the given prefix. This allows access by any host connected to the

switch specified by the given prefix. Mac Address and VCI should not appear;

ATM Address is required. See

TABLE 5-7.

c This flag allows an alternate LECS address to be specified. By default, the

SunATM software uses the well-known address specified in the LAN Emulation

standard. If, however, your LECS has a different address, or you want to

connect to the LECS over a PVC, you may provide the alternate ATM address or

VCI in a c entry. If you want to make a PVC connection, the VCI must be 17, as

required by the LAN Emulation standard. The interface and ATM address or

VCI must be included.

s This flag specifies the LES address or VCI, and instructs the system to contact

the LES directly, and to use default subnet configuration information. This flag

should be used if your subnet does not have an LECS. Without this entry, the

system first connects to the LECS, which provides the LES address and

configuration information.

m Notifies the system that the entire ATM address, including the network prefix,

must be configured manually on this interface. If your interface is connected to

a switch that does not support ILMI address registration, you must include this

option in your or /etc/opt/SUNWconn/atm/laneconfig file. Note that the

variables $myaddress, $prefix, and $localswitch_server (which use the

switch prefix obtained from the switch via ILMI) may not be used if ILMI

address registration is disabled.
