Configure the fallback address

Updated: April 10, 2026

Want to summarize with AI?

Configures a fallback static IPv4 address, subnet mask, default gateway, and optional DNS servers so the device remains reachable if it does not receive an IP address from DHCP.

This task ensures that the device remains reachable on the network by using either the default fallback IP address or a user-configured static IP address.

This task is used in provisioning mode to assign a fallback IPv4 address configuration to the device when DHCP is unavailable or does not provide an address.

Procedure

Use the configure ip address ipv4 static-IP-address static-netmask default-gateway-ip [dns-ip] command to configure fallback address.

Note

In provisioning mode, the IP address, netmask, default gateway, primary DNS, and secondary DNS can be configured using the IP command.

The device automatically sets the fallback address (192.168.0.10 by default) or the configured IP address if it does not receive an address from the DHCP server.

Example:

Device# configure ip address ipv4 static 192.168.10.2 255.255.255.0 192.168.10.1 192.168.10.200 192.168.10.201
