- Use the addr command to assign
an IP address, subnet mask, and network address to the terminal concentrator.
In the following example (Class B network, Class C subnet), the broadcast
address is the terminal concentrator's address with the host portion set to
255 (all binary 1's).
monitor:: addr
Enter Internet address [<uninitialized>]:: 172.25.80.6
Internet address: 172.25.80.6
Enter Subnet mask [255.255.0.0]:: 255.255.255.0
Subnet mask: 255.255.255.0
Enter Preferred load host Internet address [<any host>]:: 172.25.80.6
*** Warning: Load host and Internet address are the same ***
Preferred load host address: 172.25.80.6
Enter Broadcast address [0.0.0.0]:: 172.25.80.255
Broadcast address: 172.25.80.255
Enter Preferred dump address [0.0.0.0]:: 172.25.80.6
Preferred dump address: 172.25.80.6
Select type of IP packet encapsulation (ieee802/ethernet) [<ethernet>]::
Type of IP packet encapsulation: <ethernet>
Load Broadcast Y/N [Y]:: n
Load Broadcast: N
- After you finish the addr session,
power-cycle the terminal concentrator.
The Load and Active LEDs
should briefly blink, then the Load LED should turn off.
-
Use the ping(1M) command to confirm that the network connection
works.
