ALTER PORT Command

ALTER PORT is a sensitive command that alters the attributes of the specified port.

LLC2 ports are the only ports that cannot be altered using this interface.

ZPAM-MAP-ALTER-PORT is an extensible structured token that contains the attributes

for the specified port.

This token has the token number ZPAM-TNM-ALTER-PORT and the DDL definition

ZPAM-DDL-ALTER-PORT. This token must be present in every ALTER PORT

command. ZPAM-MAP-ALTER-PORT contains the following fields:

ZADDR

is the address for all traffic through the port. For Ethernet-type ports, this is the

PROTOCOL_TYPE field of the raw Ethernet header. For LLC1-type ports, this is

the DLSAP found in inbound frames and the SLSAP found in outbound frames. The

value specified can have up to four hexadecimal digits.

ZMAC-ADDR

is an optional 6-byte group MAC address, which makes this port a group port. 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 and all of them will receive any frames sent to that

address. Note that this group address overrides the adapter’s default individual

station MAC address only as far as this particular port is concerned. The group

MAC address specified can have up to 12 hexadecimal digits.
