set [node node-id] nsp ...
Modifies the attributes of the nsp entity. The modifiable
attributes and their data types [in brackets] are:
congestion avoidance [boolean]
delay factor [integer]
delay weight [integer]
flow control policy [segment flow control|no flow control]
keepalive time [seconds]
maximum remote nsaps [integer]
maximum receive buffers [integer] (OpenVMS)
maximum transport connections [integer]
retransmit threshold [integer]
1 – congestion_avoidance
Default: False Value: True or false
Enables the use of the automatic congestion avoidance mechanism.
This mechanism reduces the transport window size in response to
an indication from the Network layer.
set [node node-id] nsp congestion avoidance boolean
Example:
set nsp congestion avoidance false
2 – delay_factor
Default: 2 Value: 2-15
Factor by which to multiply the current value of the roundtrip
delay estimate status attribute in order to set a value for the
retransmission timer.
Note, the roundtrip delay estimate is an attribute of the
nsp port entity.
set [node node-id] nsp delay factor integer
Example:
set nsp delay factor 2
3 – delay_weight
Default: 3 Value: 0-255
Relative weighting to apply to the current estimate and to a
new sample when estimating roundtrip delay.
set [node node-id] nsp delay weight integer
Example:
set nsp delay weight 3
4 – flow_control_policy
Default: Segment flow control Value: Segment flow control
or
no flow control
Determines NSP flow control policy used. This attribute may not be
changed when NSP state is "on."
Flow control is the mechanism that determines when to send a Data
or expedited messages. Flow control is performed separately for
normal and expedited data. During transport connection formation,
each end of the connection determines the kind of flow control
policy it expects when acting as a data receiver. It is not
required that both end operate with the same flow control policy.
set [node node-id] nsp flow control policy control-policy
Examples:
set nsp flow control policy segment flow control
set nsp flow control policy no flow control
5 – keepalive_time
Default for Tru64 UNIX: 30 Value: 1-65535
Default for OpenVMS: 60 Value: 1-65535
Time, in seconds, that NSP waits for data to be transmitted or
received before testing a transport connection. When this timer
expires, NSP sends a data request PDU to the remote NSP. This
PDU does not change the flow control parameters, but does require
acknowledgment. For Tru64 UNIX, You can modify this
characteristic to a lower value only when the entity is disabled.
set [node node-id] nsp keepalive time integer
Example:
set nsp keepalive time 60
6 – maximum receive buffers (OpenVMS)
Default: 2000 Value: 1-65535
Maximum number of receive buffers that can store received transport
PDUs. You may not decrease the value while NSP is enabled.
set [node node-id] nsp maximum receive buffers integer
Example:
set nsp maximum receive buffers 4000
7 – maximum_remote_nsaps
Default for Tru64 UNIX: 160 Value: 1-65535
Default for OpenVMS: 201 Value: 1-65535
Maximum number of remote NSAPs that can exist concurrently. Must
be equal to or greater than the default, which equals the current
value of maximum transport connections. You can modify this
characteristic to a lower value only when the entity is disabled.
set [node node-id] nsp maximum remote nsaps integer
Example:
set nsp maximum remote nsaps 201
8 – maximum_transport_connections
Default for Tru64 UNIX: 128 Value: 0-1023
Default for OpenVMS: 200 Value: 0-65535
Maximum number of active transport connections allowed at one
time. Must not be less than the current value of maximum remote
NSAPs. You may not decrease the value while NSP is enabled.
set [node node-id] nsp maximum transport connections integer
Example:
set nsp maximum transport connections 200
9 – retransmit_threshold
Default: 12 Value: 1-65535
Maximum number of times a source nsp entity is to restart an
expired retransmission timer before the remote node is to be
considered unreachable. When the threshold is reached, NSP
sets the confidence variable to false.
set [node node-id] nsp retransmit threshold integer
Example:
set nsp retransmit threshold 12
