Enabling WAN Acceleration

After you perform the initial configuration of the WXC ISM 200, use the following procedure to enable WAN acceleration:

1. Select Configuration>Quick Configuration>WAN Acceleration>Manage in the J-Web interface to open the WXOS Web interface in a separate window (see Figure 7).

   Figure 7: Entry Page to the WXOS Web interface

   

   If you have difficulty opening multiple WXOS Web interface windows using Microsoft Internet Explorer, version 6, go to Tools>Internet Options>Temporary Internet Files>Settings and select Automatically.

2. If you already have a WX registration server, do the following:
   1. Click Device Setup>Registration Server.
   2. Click Transfer registration server.
   3. Type the IP address of your current registration server, and click Submit.

   Alternatively, change your remote WX endpoints to use the WXC ISM 200 as the registration server. WAN acceleration can occur only between endpoints that use the same registration server and belong to the same WX community (the default).

3. Log in to each remote WX endpoint where you want to establish a tunnel to the WXC ISM 200, and do the following:
   1. Click Compression>Advanced>Tunnel Mode, change the tunnel mode from IpComp (the default) to UDP, and click Submit. The tunnel mode on a WXC ISM 200 is always set to UDP, and cannot be changed.

      Caution: Traffic to remote WX endpoints will be blocked unless the tunnel mode is set to UDP.

   2. Click Compression>Endpoints and verify that a tunnel to the WXC ISM 200 is enabled.
   3. Click Acceleration to verify that TCP Acceleration to the WXC ISM 200 is enabled.
4. On the WXC ISM 200, click Compression>Endpoints to enable or disable tunnels to the appropriate endpoints. Click Acceleration to verify that TCP Acceleration is enabled. To accelerate traffic to a remote endpoint, compression and acceleration must be enabled in both directions.
5. Click Compression>Compression Subnets, select the local subnets that you want to advertise to remote endpoints for compression, and click Submit. Only the local subnet of the wx-slot/0/0 interface is advertised by default.
