Procedure 7-13: Provision TCP/IP on IAO LAN port

- Overview

Use this procedure to perform the following:

  • Enable/Disable TCP/IP on the IAO LAN port

  • Enable/Disable Proxy Address Resolution Protocol (Proxy ARP) on the IAO LAN port

  • Provision the IP address and IP Subnet Mask of the IAO LAN port

  • Provision IP Default Router Address if connecting to a default router.

- Privilege level

You must log in as a Privileged user to complete this procedure.

- Before you begin

Prior to performing this procedure:

  1. Refer to Before you begin and Required equipment in this chapter.

  2. Obtain the work instructions for this procedure.

  3. Obtain the IP Address and IP Subnet Mask of the IAO LAN port and the IP Default Router Address if it is connecting to a default router.

Steps

Perform the following steps to complete this procedure.

 
1

From the System View menu, select Administration → Data Communications.

Result:

The Data Communications window opens.

2

Click on the TCP/IP tab.

Result:

The TCP/IP parameters appear.

3

Select and/or modify the following parameters:

  1. Select the Port Aid: (lan-1) being provisioned.

  2. Select Enable to enable the TCP/IP function, or Disable to disable the TCP/IP function. Disabling the TCP/IP function on an IAO LAN port also causes enabled Proxy ARP to be disabled for the IAO LAN port.

    The TCP/IP function can be enabled and the IP address, Subnet Mask, and Default Router defined for the first time without a system reset occurring. After the initial provisioning, future changes to the IP address, Subnet Mask, or Default Router while TCP/IP is enabled results in a system reset. In addition, any time TCP/IP is disabled and then enabled again, the system resets.

    If OSI communications is disabled on LAN-1, TCP/IP function for LAN-1 cannot also be disabled. Refer to Procedure 7-10: Enable/disable OSI on IAO LAN port.

  3. Select Enable to enable the Proxy ARP, or Disable to disable the Proxy ARP. To enable Proxy ARP on the IAO LAN port, the TCP/IP Function must also be enabled.

    For applications that require IP connectivity between IP-based operations systems and remote network elements (for example, SNMP and Network Time Protocol), enabling Proxy ARP on the Gateway Network Element (GNE) eliminates the need for static routes on the external router or OS host that is connected to the GNE using the IAO LAN interface.

  4. If the TCP/IP function is enabled, one at a time, click the Modify button to set the IP Address and IP Subnet Mask of the LAN-1 port and the IP Default Router Address, if it is connecting to a default router.

    When the provisioning window opens for the IP address being provisioned, enter the IP address as four dot-separated decimal numbers ranging from 0 to 255. Click OK to make your changes or Cancel to quit.

For an OS to establish a TCP/IP connection to or through this Network Element, the IP address must be entered at the TL1 TCP/IP GNE to authorize access. Refer to Procedure 7-14: Provision/enable/disable the NE as a TL1 TCP/IP GNE.

4

Click Apply to make the changes.

Result:

A warning appears asking you to confirm executing this command.

5

Click Yes to execute the command.

Result:

If you made changes and enabled the TCP/IP function, the changes are applied, the system resets, and you are logged off the system. If you made changes and disabled the TCP/IP function, the changes are applied. The system does not perform a reset.

6

If required, click Close to exit.
