name - Define Port Names
The
name
command allows the user to assign names to each of the ports.
Ports with identical names are grouped
together
since commands can be issued to control the boxes by name or by port number.
The Port Names can be changed to any string of
1 to 16 characters
(including all printable characters) not including
‘space’ or ‘comma’. Port names cannot start with a number.
PDU 4/4> help name
Syntax: name <b> <p> <n>
Description: Max.16 alphanumeric characters. The name must not start with a number.
<b> = (box # | all) <d> = disable <dly> = delay <e> = enable
<n> = name <t> = time <p> = (port # | name | all)
Ports and Boxes may be referred to by
al
l,
name
(implying a group) or
number
.
Ranges of ports may be specified as 1-4 = 1,2,3,4.
All
may also be used.
The
Define Port Names
command allows the user to give each port an
alias
and allows the grouping of outlets. The
Port Number is not changed or affected by renaming the port and may always be used to control the port.
Examples:
•
name 1 Sun 1,3,5
assigns the alias of
Sun
to Box 1, Ports 1, 3, and 5
•
name 0 Sun 1-4
assigns the alias of
Sun
to all Boxes, ports 1 through 4
•
name 0 Sun ALL
assigns the alias of
Sun
to all Boxes, all ports
Default names are ‘DEVICE1’ through ‘DEVICE8’ for Ports 1-8, respectively.
Port Names must be between one and sixteen characters and can include any printable
characters except for ‘space’
or ’comma’. Port names cannot start with a number.
Port Groups
Port Groups can be created and controlled by assigning identical names to two or more ports. All ports with identical
names within one PDU 4/4 are grouped together provided the user enters an operational command for that name.
All ports with identical names in ALL daisy-chained PDU 4/4 chassis will be controlled provided the user enters a
valid GLOBAL (box ID = 0) command.
