INFO PORT Command
INFO PORT Display for LLC1 Ports
The display for the INFO PORT command for LLC1 ports has this format:
TYPE
is the port type.
ADDRESS
is the address for all traffic through the port. For Ethernet-type ports, this attribute
is the protocol-type field of the raw Ethernet header. For LLC1-type ports, this
attribute is the Destination Service Access Point (DSAP) found in inbound frames
and the Source Service Access Point (SSAP) found in outbound frames.
GROUPMACADDRESS
is a locally administered MAC address. The adapter listens for frames that contain
this group address at the MAC level instead of frames that contain the
individual-station MAC address. Several adapters can have the same group MAC
address. All of them will receive any frames sent to that address. This group
address overrides the adapter’s default individual-station MAC address only for this
particular port. The macaddress value must be specified as 12 hexadecimal digits
with bit 0 of byte 0 set to 1. The keyword DEFAULT is used to change a port’s
GROUPMACADDRESS back to the adapter’s default MAC address. (See the
ALTER Command on page 3-14.)
DELIVERYMODE
indicates how READ requests are queued. SERIAL means all READs are queued
together and serviced first-in, first-out. PARALLEL means READ requests are
queued by the opener of the port. Inbound messages are delivered to each opener
of the port that has a READ posted.
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. LLC2ENABLED is valid only for LLC1 port types on TRSA or E4SA.
