Configuring the ADTRAN Router ADTRAN Routers with CradlePoint CBA750B 4. Enter Enable mode by entering enable at the prompt as follows: >enable 5. Enter your Enable mode password at the prompt. The default Enable mode password is password. If your product no longer has the default Enable password, contact your system administrator for the appropriate password. 6.
ADTRAN Routers with CradlePoint CBA750B Configuring the ADTRAN Router The configuration example below configures the LAN using the default VLAN 1. The ip address command is used to specify a static ip address and subnet mask for the interface, and the ip policy route-map CPACCESS command enables policy-based routing to allow PCs on the VLAN to access the CBA750B for configuration and management.
Configuring the ADTRAN Router ADTRAN Routers with CradlePoint CBA750B To configure policy classes and access lists for the primary and WAN failover connections, enter the following commands at the specified command prompts: (config)#ip access-list extended self (config-ext-nacl)#permit ip any any (config)#ip access-list extended AdminAccess (config-ext-nacl)#permit tcp any any eq https log (config-ext-nacl)#permit tcp any any eq ssh log (config)#ip access-list extended NAT1 (config-ext-nacl)#permit ip any
ADTRAN Routers with CradlePoint CBA750B Configuring the ADTRAN Router In the example configuration below, the ip address dhcp command is used to configure the Ethernet interface to the CBA750B to learn its IP address using DHCP, and assign it an administrative distance of 10. Additionally, the ip access-policy command is used to assign the Public2 ACP to the interface.
Configuring the ADTRAN Router ADTRAN Routers with CradlePoint CBA750B The steps in this section show a basic configuration. For detailed configuration information, refer to Configuring WAN Failover with Network Monitor in AOS available from the ADTRAN support community at https://supportforums.adtran.com.
ADTRAN Routers with CradlePoint CBA750B Configuring the ADTRAN Router To configure the track for monitoring the PRIMARYPROBE probe, enter the following commands at the specified command prompts: (config)#track PRIMARYTRACK (config-track-PRIMARYTRACK)#test list or (config-track-PRIMARYTRACK-test)#if probe PRIMARYPROBE (config-track-PRIMARYTRACK)#no shutdown Step 3: Configure Policy-based Routing for the Probe Configure policy-based routing to force the probe to only route out of the primary WAN Ethernet
Configuring the ADTRAN Router ADTRAN Routers with CradlePoint CBA750B Step 5: Disable the Reverse Path Forwarding Check Disable the reverse path forwarding (RPF) check on the ACP associated with the primary WAN interface to avoid the possibility that the return probe traffic is not dropped while the backup connection is active.

Configuring the CradlePoint CBA750B ADTRAN Routers with CradlePoint CBA750B Configuring the CradlePoint CBA750B The following sections provide general instructions for configuring the CradlePoint CBA750B for integration with an ADTRAN Router. Refer to the CradlePoint CBA750B User Manual for detailed instructions on how to configure the CBA750B.
ADTRAN Routers with CradlePoint CBA750B Configuring the CradlePoint CBA750B 1. On the right side of the CBA750B router, identify the miniature sliding switch labeled with an O and I. The switch should be adjacent to the ExpressCard slot. 2. Slide the switch to the I position to enable Passthrough mode. If the router is receiving power, the LED under the switch will be unlit while the unit is in Passthrough mode.
Configuring the CradlePoint CBA750B ADTRAN Routers with CradlePoint CBA750B 3. Enter the administrator password for the CBA750B in the Password field. The default login password is the last 8 characters of the CBA750B MAC address. Then, select Login. Step 7: Verify Modem Activation with Verizon Normally, no additional configuration is required to activate the modem with Verizon.
ADTRAN Routers with CradlePoint CBA750B Configuring the CradlePoint CBA750B Step 8: Enable the Force 24 Subnet Option The CradlePoint CBA750B must be configured with the Force 24 subnet option for reliable operation with Verizon and other wireless 3G/4G LTE service providers. Verizon uses GGSN to assign wireless user IP addresses. These addresses may fall on a subnet boundary and cause routing issues. To avoid these issues, the Force 24 option must be enabled.
Additional Resources ADTRAN Routers with CradlePoint CBA750B 4. Use the Subnet Selection Mode drop-down menu to select Force 24 Subnet Then, select the Submit button to save the change. Additional Resources There are additional resources available to aid in configuring your ADTRAN router. Many of the topics discussed in this guide are complex and require additional understanding, such as using the CLI,WAN Failover, and Network Monitoring.
