Point-to-Point Network Interface Configuration
Fields Network hop
count This is the maximum number of hops that a packet
entering the network can make. It is the distance
between the two most remotely separated nodes on the
network. Distance is measured in terms of hops, where
each intermediate node between two end nodes is
counted as a hop.
The network hop count determines a packet’s time to
live; that is, the time (in numbers of hops) that a packet
is allowed to remain in the network. A packet whose
time to live has expired can be assumed to be
undeliverable because of some undetected routing
anomaly and will be discarded. If this value is set too
low, the danger exists that packets will be discarded
prematurely (that is, before they reach their
destination). If the value is set too high, an
undeliverable packet may remain in the network too
long, and possibly contribute to network congestion.
Default value: None
Range: 1–1024
Idle device
timeout value
(seconds) This field is relevant only if the link is a dial link. For
those devices that have the idle device timer enabled, if
there is no activity during this time interval, the device
is considered to be inactive and will be shut down. A
timeout value of zero disables the idle device timer for
the link on this network interface, thus overriding any
enabled device timer, see “Related screens.” The
purpose of the idle device timer is to shut down dial
links that have become idle.
Related screens:
• NETXPORT.NI.
NIname .LINK. linkname
An entry in this screen enables/disables the idle
device timer.
• NETXPORT.GPROT.TCP
The connection assurance interval set in this screen
must be less than the idle device timeout value
configured in the current screen.
Default value: None
Range: 0–32400
