Configuring Dial Backup and Remote
Management
The Cisco 800 series access routers support dial-in (for remote management) and dial-out (for dial
backup) capabilities. By allowing you to configure a backup modem line connection, the Cisco
800
series access routers provide protection against WAN downtime. Dial backup is inactive by default,
and
must be configured to be active.
Dial backup functions can be configured as follows:
• Through the auxiliary port on any Cisco 870 series router
• Through the ISDN S/T port on a Cisco 876 with an advanced enterprise
(c870-adventerprisek9-mz)

Remote management functions can be configured as follows:
• Through the auxiliary port on any Cisco 850 or Cisco 870 series router
• Through the ISDN S/T port on the Cisco 876 and Cisco 878 routers
Note The console port and the auxiliary port in the Cisco IOS software configuration are on the same physical
RJ-45 port; therefore, both ports cannot be activated simultaneously, and the command-line interface
(CLI) must be used to enable the desired function.
This chapter contains the following topics:
• Dial Backup Feature Activation Methods
• Dial Backup Feature Limitations
• Configuring Dial Backup and Remote Management Through the Console or Auxiliary Port
• Configuring Dial Backup and Remote Management Through the ISDN S/T Port
