NETCONTROL UPDATE
Dynamically updates selected network transport parameters and
configuration information.
Syntax
{INTERNET}
{MAPPING }
NETCONTROL UPDATE= {NETDIR }; {NET=niName }
{X25 } {GATE=gatehalfName}
{ALL }
Parameters
{INTERNET}
{MAPPING } Specifies which configuration areas will be dynamically
UPDATE = {NETDIR } updated. The areas possible depends on the network type
{X25 } (see Table 7-2).
{ALL }
INTERNET Adds to IPU all gateway data
currently configured fort he
specified network interface or
gateway half, meaning all gateways
appearing in the NMMGR Neighbor
Gateways screen (subtree
NETXPORT.NI.niname.INTERNET) and all
Reachable Network data configured
under each of those gateways. These
screens contain information
describing the gateways for all
directly connected networks and
gateway halves, as well as all
networks the gateways can reach.
Valid for all NI types except
Loopback.
MAPPING Adds all router mappings currently
configured for the specified router
network interface, to that NI's
mapping table, meaning all mappings
appearing in that NI's NMMGR
Point-to-Point Mapping Configuration
screen and the Point-to-Point
Reachable Nodes screens under it.
Information will be overlaid based
on matching IP-Device mapping
records. This allows changing
routes as well as adding new
reachable nodes. Valid for router
NI types only.
NETDIR Adds all currently configured
Network Directory (NSDIR.NET.SYS)
entries, whose address types apply
to the specified network interface's
type, to the mapping table for that
NI. Valid for LAN, FDDI, and Token
Ring NI types only.
X25 Adds all currently configured
Network Directory (NSDIR.NET.SYS)
entries having X.25 or IP address
types and matching entries in the
NMMGR X.25 SVC Address Key Paths
screen, to the specified X.25
network interface's mapping table
and X.25 protocol module. This
allows adding new SVC destinations
or adding a new node to the L.U.G.
(Local User Group) table. Valid for
X.25 NI types only.
ALL The control process will update all
areas which apply to the specified
network interface or gateway half's
type. Areas not supported for that
NI type will not be updated.
Updating will occur in this order:
INTERNET, MAPPING, NETDIR, X25.
NET=niName Specifies the name of a configured network interface
to be updated, which has already been started. Enter
any valid NI name from the NMMGR Network Interface
Configuration screen which is not a gateway half. If
the specified NI is not configured and started, a
"NOT STARTED" error will occur.
GATE=gatehalfName Specifies the name of a configured gateway half
network interface to be updated, which has already
been started. Enter any valid gatehalf NI name from
the NMMGR Network Interface Configuration screen. If
the specified NI is not configured and started, a
"NOT STARTED" error will occur.
Discussion
The update function updates transport with certain configuration changes
already made through NMMGR. In this way, those kinds of changes can
become active without having to first take down and then restart the
network or the entire transport.
The types of changes which can be updated are those concerned with
addresses of reachable nodes and networks ONLY; others, such as timeout
changes, require stopping and restarting transport to take effect.
UPDATE's keywords (NETDIR, INTERNET, etc.) localize which kind of
configuration data will be updated. This command can be entered at any
time after the specified NI has been started.
Not all options are valid for all network interface types. The following
table summarizes the applicability of the various UPDATE options to each
NI type:
Table 7-2. NETCONTROL Update
-------------------------------------------------------------
| | |
| NI Type | Valid Update Options |
| | |
-------------------------------------------------------------
| | |
| FDDI | INTERNET, NETDIR, ALL |
| | |
| GATEHALF | INTERNET, ALL |
| | |
| LAN | INTERNET, NETDIR, ALL |
| | |
| LOOP | ALL |
| | |
| ROUTER | INTERNET, MAPPING, ALL |
| | |
| TOKEN | INTERNET, NETDIR, ALL |
| | |
| X.25 | INTERNET, X25, ALL |
| | |
-------------------------------------------------------------
NOTE Dynamic updating is additive, so obsolete data can accumulate,
possibly resulting in table overflows. If table overflows do occur
which prevent access to the desired nodes, transport must be
stopped and restarted to clear the condition.
Example
To update the "LAN1" network with new node addresses just added to the
Network Directory (NSDIR.NET.SYS), enter
:NETCONTROL UPDATE=NETDIR; NET=LAN1
