Basic “G” Command:
Action From Syntax
Modify Host G command_name {
arguments… } ~
Query Host G command_name {
arguments… } ~
Query Response Router G command_name { arguments… } ~
Modify is Protected: Yes
Report Changes: No
The command "G" is used to query or modify a router configuration parameter or
parameters.
Summary lines at the start of each command section describe, for each type of command
action (Modify, Query, or Query Response), whether the command is sent to the router or
from the router and what the syntax of the command is. They also indicate whether or not
the modify form of the command is password-protected or not (“Modify is Protected”) and
whether or not the command participates in automatic reporting of parameter changes
(“Report Changes”) as described under the “G REPORT_CHANGES” command.
Each command has three possible syntax forms:
1.
Modify: this form is sent to the router to modify a parameter value
2.
Query: this form is sent to the router to query for a parameter value
3. Query Response: this form is sent by the router to report the value of a parameter in
response to receiving a Query or in response to a change in the parameter value when
automatic reporting of parameter changes is turned on.
Generally, the command arguments identify the parameter that is being queried or
modified, and provide its new value if it is being modified. The first argument following the
“G” command character is a command name. Additional arguments may be required for
some command names to completely specify the parameter in question. After those, one
or more additional optional arguments may give a new value for the parameter. All
arguments are separated from one another by commas.
When the Modify form of the command is used and if the new value is a valid value, the
router will change the parameter value to this new value, providing that “Modify is
Protected” says “No” or the administrator password has been sent using the “K”
command. It will then report the new value to all router control ports that have requested
these reports, providing that “Report Changes” says “Yes”. If a new value is provided that
is an illegal value, the parameter is left unchanged and no “G” command is sent.
When the Query form of the command is used, the Query Response form of the
command is returned to the control port that sent the Query command, reporting the
current value of the parameter. The Query form of a command is normally the same as
the Modify form except that the new parameter values are not included. The Query
Response form of a command is normally the same as the Modify form (but of course the
sender and receiver are reversed in these two cases).
Some “G” commands may initiate an action or report the occurrence of an event, instead
of querying or changing a router parameter.
Commas are used to separate arguments in the “G” command.
Space characters should not appear within the “G” command arguments, except when
they appear within strings. Also, a single space character is allowed after the “G”
