Table of Contents

When disabled, the DSR signal is not required to connect to a slave line, and DSR is not required

to activate a CLI line (see Modem Signals on page A6-1 for details on using need_dsr in conjunction

with modem control). DSR is always considered active on ports that do not have a DSR signal (ports

with partial modem control lines). A Y enables this parameter, an N disables it. The default is N.

net_inactivity

This asynchronous port parameter deﬁnes the amount of time that network protocols (for example,

SLIP, PPP, ARAP) running on the serial line can remain inactive before the port is reset. Valid

options are 0 to 255; a zero value indicates off. The default is 0 (off).

Use this parameter in conjunction with net_inactivity_units.

This asynchronous port parameter deﬁnes the units of time used for the port's inactivity timer. Valid

options are minutes or seconds. The default is minutes.

Use this parameter in conjunction with net_inactivity.

To set an inactivity timer of two minutes, set:

net_inactivity_units=minutes

net_inactivity=2

To set an inactivity timer of 30 seconds, set:

net_inactivity_units=seconds

net_inactivity=30

NOTE: Because the accuracy of the inactivity timer is within ﬁve sec-

onds, if net_inactivity_units is set to seconds, Bay Networks recom-

mends using a value for net_inactivity that is a multiple of ﬁve.

NOTE: If you are using an ISDN line, it is important to set

net_inactivity to a small value, such as 30, and net_inactivity_units to

seconds; otherwise, you may incur high costs from your ISDN service
