This command displays the ANCB/DN link state table. The link state
table indicates, for each link, whether or not the link is currently "up,"
"down," or undergoing link validation ("check"). For DataNET links, the
table also gives the device to which the link connects. Devices are
identified by IP address. For example:
local> display links
Port status for 172.16.9.239, Port1 - DataNET A, Port2 - DataNET B
Port: Medium: Status:
1 Copper Connected
2 Copper Connected
Ethernet Up
This command may be used to override default values for several
parameters related to the DataNET protocol. Specific forms of the
command are:
dn setuptime
dn setuptime time
Connected to:
172.016.099.003, 4A
172.016.099.003, 4B
Displays the current "setup time" value, in
microseconds. This is the time that the
ANCB_DN board will transmit a
"preamble" pattern on a DataNET link
before starting the actual data frame. The
preamble allows time for the receiver
circuitry at the far end of the link to adjust
to the incoming signal's amplitude, phase,
and frequency. The default setup time is
3.5 milliseconds.
Sets the DataNET setup time to the value
given, in microseconds. The new setup
time value is saved in non-volatile
memory.
Time is entered in microseconds.
Example: 3.5 milliseconds is entered as
3500.
