Configuring Dial Backup and Remote Management Through the
Console or Auxiliary Port
When customer premises equipment, such as a Cisco 850 or Cisco 870 series router is connected to an
ISP, an IP address is dynamically assigned to the router, or the IP address may be assigned by the router
peer through the centrally managed function. The dial backup feature can be added to provide a failover
route in case the primary line fails. Cisco 850 and Cisco 870 routers can use the auxiliary port for dial
backup and remote management.
Note The cable modem environment is currently not supported.
