Set Link Configuration Command (SC)

The Set Link Configuration command allows the user to modify various local and remote node configuration parameters. This includes the node's Station Address, Download Server Station Address, and File Server Station Address. In addition, the Receive Packet Filter mode, Retry Limit, Save Bad Packet flag, and Trace Mode flag can be set.

Caution Users should consult with a System or Network Manager prior to modifying local or remote configuration parameters.

The syntax for the Set Link Configuration command is:

SC,[ADR],PAR#[,[PAR-value][,[option][,LU#]]]

where:

 

ADR

This is the •target" Station Address; that is, the node whose configuration

 

parameters are to be set. It is entered as 6 pairs of hexadecimal digits

 

separated by hyphens. See Table 5"1 for default addresses.

PAR#

This parameter is a required entry and must be specified as one of the

 

following integers: 1, 4, 5, 6, 7, 9, or 10. Table 5"6 shows the meaning of

 

each PAR# integer.

PAR-value

For the PAR# parameter specified above, the PAR-valueparameter

 

provides the new value to be set. If not supplied, it is defaulted. See

 

Table 5"7 for the possible PAR-valuesettings available and default values

 

associated with each PAR# entry.

option

•P" or •T" may be entered for NOVRAM"stored parameters (PAR#

 

integers 1, 4, 5, 6, 7, or 9).

 

If P is entered, the parameter specified by PAR# is modified in both RAM

 

and NOVRAM. Because the NOVRAM value is modified, the change is

 

•permanent".

 

If T is entered, the parameter is modified in RAM only. This change is

 

•temporary" because NOVRAM contents are not affected. T is the default

 

entry if option is not specified.

 

Note that parameters never stored in NOVRAM (for example, File Server

 

Station Address, PAR# = 10) are not permanent regardless of the option

 

specified and will be lost if the Node Manager software is terminated.

LU#

This is the Logical Unit number that identifies the LANIC card through

 

which a command is transmitted and from which a response is received.

 

LU# is a number in the range 2 to 255 (decimal) established during system

 

generation; hence, it always applies to a local LANIC card. See Table 5"1

 

for default values.
