Technical data

Source stack name TCP/IP process name to use. The value of the stack entries in the
OSMCONF file (see “Configuring Additional TCP/IP Processes for
OSM Connectivity” (page 18)) should not be more restricted than this
one.
Source IP IP address that OSM will bind to when sending the indication. The
values of the stack entries in the OSMCONF file (see “Configuring
Additional TCP/IP Processes for OSM Connectivity” (page 18)) should
be chosen to allow use of the desired Source IP entry.
Destination IP Optional parameter used to restrict this entry to only apply to one
destination.
Destination Port Optional parameter used to restrict this entry to only apply to one port
on the specified destination IP. Destination IP is required when
Destination Port is specified.
Multiple source IP addresses may be specified by using multiple IndicationSource flags. If
there are multiple source IP addresses specified, OSM will try to send from each of them until it
has either failed with all source IP addresses or it successfully sends to the endpoint.
If there are any IndicationSource flags specified, OSM will only use the IndicationSource
flags for sending indications, any stack flags specified will only be used for incoming connections.
NOTE: OSM will always attempt to send via $ZTCP0 and $ZTCP1. If there is at least one
matching IndicationSource flag, the IndicationSource flag(s) will be attempted first, then
$ZTCP0 and $ZTCP1.
Configuring Additional TCP/IP Processes for OSM Connectivity
OSM has two default TCP/IP processes, $ZTCP0 and $ZTCP1, which are used for OSM Service
Connection and OSM Event Viewer connectivity. The physical connections (two for fault tolerance)
are made through either a Gigabit 4-port ServerNet adapter (G4SA) in an IOAM or VIO enclosure
or an E4SA, FESA, or GESA in an attached S-series IOMF2 CRU. OSM Low-Level Link connectivity
for NS-series servers is established through the maintenance entity (ME) of the ServerNet switch
board in each p-switch (using the IP address of the p-switch). This section describes how to configure
(optional) additional TCP/IP processes for OSM Service Connection and OSM Event Viewer
connectivity.
Edit the OSMCONF file to specify TCP/IP processes other than the default $ZTCP0 and $ZTCP1
processes for use by the OSM Service Connection, HP SIM, or Insight Remote Support Advanced:
stack = <TCPIP process name>
stack = <TCPIP process name 2>
For example:
stack = $ZTC00
stack = $ZTC01
To specify TCP/IP processes other than the default $ZTCP0 and $ZTCP1 for use by the OSM Event
Viewer, add the following additional lines to OSMCONF:
evtstack = $ZTC00
evtstack = $ZTC01
The stack and evtstack entries are independent. Use of the stack entry by itself does not
affect IP addresses available for the OSM Event Viewer.
Both the OSM Service Connection and the OSM Event Viewer automatically work with the IP
addresses for $ZTCP0 and $ZCTP1. No additional entry is required.
