Session-Layer Counters:
Description:
Refuse SPDU Sent No Reason
The number of times this session entity sent a
S-CONNECT.response (reject) event with a provider reason
member indicating no reason given.
Refuse SPDU Received Permanent
The number of times this session entity received a
S-CONNECT.confirm (reject) event with a provider reason
member indicating SSAP indentifier unknown or proposed
protocol version(s) not supported.
Refuse SPDU Sent Permanent
The number of times this session entity sent a
S-CONNECT.response (reject) event with a provider reason
member indicating SSAP indentifier unknown or proposed
protocol version(s) not supported.
Refuse SPDU Received Temporary
A count of the number of times this session entity received a
S-CONNECT.confirm (reject) event with a provider reason
member indicating session service user (presentation layer) is
not attached to the SSAP or congestion at connection time.
Abort SPDU Received No Reason
The number of times this session entity received a
S-P-ABORT.request event with a reason indicating
unspecified.
Abort SPDU Sent No Reason
The number of times this session entity sent a
S-P-ABORT.request event with a reason indicating
unspecified.
Abort Sent Protocol Error
The number of times this session entity sent a S-P
ABORT.request event with a reason indicating protocol errors.
Current session buffer usage
This is a count of the number of buffers the session layer is
using.
Highest level of session buffer usage
This is a measure of the maximum value that the counter listed
above has reached.
The following table lists the Transport–Layer attributes for the OSI
coprocessor.
Transport-Layer Parameters:
Description:
Inactivity Time
An integer that specifies the maximum time that may pass
before a transmitted TPDU is received by the peer transport
entity. If a TPDU is not received within this time, transport
closes the connection.
Local Retransmission Time
An integer that specifies the maximum time that this transport
entity will wait for an acknowledgement of a previously
transmitted TPDU.
Maximum Number of Retransmissions
An integer that specifies the maximum number of times that
this transport entity will retransmit a TPDU without receiving an
acknowledgement (assuming the TPDU requires an
acknowledgement).
Connect Request Congestion Limit
A threshold level on the Connect Request Congestion counter.
Connect Request Configuration Err. Det.
Limit
A threshold level on the Connect Request Configuration Error
counter.
Connect Request Refused Configuration
Error Limit
A threshold level on the Connect Request Refused
Configuration Error counter.
