Configuring Static IP Address and Route

This describes how to configure the static IP address and route for a BTS that works in IP over E1 mode.

Prerequisite

You have logged in to the BTS through the SMT.

Context

CAUTION: Before configuring the route, set Static IP Switch to ENABLE, and set the IP address of the

BTS. If static IP address is applied, a BTS cannot obtain routes automatically. That is, all routes

must be configured at the near end. At least one route must be configured, with DST IP set to the IP address of the BSC and Gateway set to the IP address of the peer device.

Currently, PPP links and MLPPP links do not support next hop routing. Therefore, only the output port IP address can be configured and the next hop IP address cannot be configured for a PPP link or MLPPP link.

A newly-configured route will overwrite the original one.

This section takes the following IP addresses as an example:

Item Value

IP address and mask of the BSC 10.10.1.1/24

IP address and mask of the BTS 10.10.2.2/24

IP address and mask of the BSC peer device 10.10.1.2/24

IP address and mask of the BTS peer device 10.10.2.1/24

Procedure

1. In the left pane of the Site Maintenance Terminal System window, click Site. In the right pane of the window, double-click IP OVER E1 Config.

The IP over E1 Config window is displayed.

2. Click the Config Static IP tab.

The Config Static IP tab page is displayed.

3. Click Config Static IP.

The IP Over E1 Static IP dialog box is displayed.

4. Configure the static IP address.

a. In the IP Over E1 Static IP dialog box, click the Config tab.

b. Set Static IP Switch to ENABLE.

c. Set Communication Type to PPP/MP IP.

d. Set the IP addresses and masks of the BTS and the BSC.

e. Click OK, as shown in Figure 1.

5. Query the IP address configuration

a. In the IP Over E1 Static IP dialog box, click the Query tab.

b. Click Query.

The IP address configuration that has taken effect is displayed in the Query Result area, as shown in Figure 2.

c. Set DST IP, DST IP Mask, Interface Type, Interface No, PRI, and Router Num according to the actual situation.

d. Click Add to add a route.

To add several routes, repeat 6.c to 6.d.

To remove a configured route, select the route in the list, and click Delete.

e. Click Config Para to send the configured data to the BTS.
