ADD PORT Command
change a port’s GROUPMACADDRESS back to the adapter’s default MAC
address.
LLC2ENABLED
allows LLC1 ports to provide send and receive access to LLC2 connection-oriented
frames. The implementation of the LLC2 protocol is the responsibility of your
application.
Specifying the LLC2ENABLED attribute allows applications to send and receive
LLC2-type frames over LLC2-enabled LLC1 ports. To format or interpret SDUs to
be sent to or received from the LLC2-enabled LLC1 ports on PAM over Ethernet,
the applications need to use structures:
ZL2S-DDL-LLC1-SDU-HDR-DEF
ZL2S-DDL-LLC2-SDU-HDR-DEF
structures to format or interpret SDUs to be sent to or received from the LLC2-
enabled LLC1 ports on PAM over Ethernet.
The G05 and previous product versions of PAM do not allow this feature. It is only
applicable for the LLC1 port type of PAM over Ethernet. It is not applicable for
token ring.
REQUESTSIZE integer
is the maximum size, in bytes, of a message that the port can write and read. This
value cannot be larger than the LINE’s MAXREQUESTSIZE. (You can display this
value using the INFO LINE command.) The range of values is 1 through 32000
bytes. The minimum value that must be specified in this field is 32 bytes for LLC1-
type ports and 49 bytes for Ethernet-type ports. The default is 32000 bytes.
TYPE { ETHERNET | LLC1 }
is the PORT object subtype. This attribute is required. It cannot be changed using
the ALTER command.
Considerations
•
PORT objects define an access point to a particular service, as determined by the
PORT object subtype ETHERNET, LLC1, LLC2.
•
A single PORT name can be used on different adapters or lines ($PAMA.#PORT1,
$PAMB.#PORT1). However, it is less confusing if each PORT object is given a
unique name, regardless of which adapter or line it is associated with.
•
The ADD command leaves the PORT in the STOPPED summary state. You must
START the PORT after it has been added.
Note. You cannot add LLC2-type ports using the PAM SCF ADD PORT command. The
SNAX OPEN SAP command adds and starts the LLC2 port.
