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:

Port status for 172.16.9.239, Port1 - DataNET A, Port2 - DataNET B 

Port:    Medium:  Status:           Connected to: 

1        Copper   Connected       172.016.099.003, 4A 

2        Copper   Connected       172.016.099.003, 4B 

 

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 

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. 

dn setuptime time 

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.
