Telnet timer values in profile display

Question & Answer


Question

Why does the Telnet profile display reflect some PARMSGROUP based timer values but not others?

Cause

The IP Configuration Guide section for the INACTIVE family of timers makes the following statement:

"The timer with the smallest value defined in TELNETGLOBALS, TELNETPARMS or PARMSGROUP for that port profile is used to define how often connections are checked."

A detailed profile display for that port does not, however, always reflect the smallest timer value coded.

Answer

The following example will be used as an illustration. Telnet timer values are specified in three statement blocks:

TELNETGLOBALS

SCANINTERVAL 1900


TIMEMARK 10900
INACTIVE 3800

TELNETPARMS PORT 23

SCANINTERVAL 1800


TIMEMARK 10800
INACTIVE 3600

PARMSGROUP

SCANINTERVAL 120


TIMEMARK 180
INACTIVE 1140

Output from a profile display command:

D TCPIP,,T,PROF,PORT=23,DET

indicates the following values:

TIMERS
INACTIVE 3600
SCANINTERVAL 120
TIMEMARK 10800

Note that the SCANINTERVAL value reflects the PARMSGROUP specification yet the INACTIVE and TIMEMARK values are from TELNETPARMS.

The D TCPIP,procname,T,OBJECT,PORT=ALL,PROFILE=CURRENT,TYPE=
PARMSGRP,ID=parmsgroupname


command should be used to obtain the information you need. The PROFILE DETAIL display is not designed to reflect changes at the PARMSGROUP level. However, a change will be seen in the SCANINTERVAL value when PROFILE DETAIL is used because only one SCANINTERVAL for a port is used. The value used will be the smallest value coded in TELNETGLOBALS, TELNETPARMS, or PARMSGROUP. So, if a smaller value for SCANINTERVAL is coded in a PARMSGROUP, that value will be used.
