Setting the IP Address
The IP address is the address used by the SNMP or Telnet system to access the
DSU/CSU (see Appendix F,

IP Network Addressing Scenario

). For DSU/CSUs
using PPP, the IP address can be negotiated if the network device (e.g., router or
SNMP manager) supports such negotiation. The IP address is composed of four
fields with three digits per field (

xxx.xxx.xxx.xxx

).
The IP address is set for the COM port or the AUX port (with LAN Adapter or
daisy chain), depending on which one has been chosen as the SNMP or Telnet
communications link. The example below assumes that an IP address of
010.155.111.222 is being set for the COM port. You can use the same principles
to assign any value (between 000 and 255 for each digit field) to other ports.
Procedure
To assign an IP address to the COM port:
1. From the Main Menu screen, select Configuration.
2. From the Load Configuration From screen, select Current.
3. From the Configuration Edit/Display screen, select Management and
Communication.
4. From the Management and Communication screen, select Communication
Protocol.
5. In the Communication Port’s IP Address field, enter the IP address for the
COM port. Enter the subnet mask under this.
6. When you are through making configuration option changes, select Save to
store these changes in nonvolatile memory. If you want to return to the User
Interface screen, press your Esc key and then save your changes from that
screen.
