Chapter 4 Configuring Cisco IOS Configuration Engine
Configuring Cisco IOS Agents
To disable the CNS Cisco IOS agent, use the no cns config initial {ip-address | hostname} global
configuration command.
This example shows how to configure an initial configuration on a remote switch when the switch
configuration is unknown (the CNS Zero Touch feature).
Switch(config)# cns template connect template-dhcp
Switch(config-tmpl-conn)# cli ip address dhcp
Switch(config-tmpl-conn)# exit
Switch(config)# cns template connect ip-route
Switch(config-tmpl-conn)# cli ip route 0.0.0.0 0.0.0.0 ${next-hop}
Switch(config-tmpl-conn)# exit
Switch(config)# cns connect dhcp
Switch(config-cns-conn)# discover interface gigabitethernet
Switch(config-cns-conn)# template template-dhcp
Switch(config-cns-conn)# template ip-route
Switch(config-cns-conn)# exit
Switch(config)# hostname RemoteSwitch
RemoteSwitch(config)# cns config initial 10.1.1.1 no-persist
Step 14 cns config initial {hostname | ip-address}
[port-number] [event] [no-persist] [page page]
[source ip-address] [syntax-check]
Enable the Cisco IOS agent, and initiate an initial
configuration.
For {hostname | ip-address}, enter the hostname or the
IP address of the configuration server.
(Optional) For port-number, enter the port number of
the configuration server. The default port number is 80.
(Optional) Enable event for configuration success,
failure, or warning messages when the configuration is
finished.
(Optional) Enable no-persist to suppress the
automatic writing to NVRAM of the configuration
pulled as a result of entering the cns config initial
global configuration command. If the no-persist
keyword is not entered, using the cns config initial
command causes the resultant configuration to be
automatically written to NVRAM.
(Optional) For page page, enter the web page of the
initial configuration. The default is /Config/config/asp.
(Optional) Enter source ip-address to use for source IP
address.
(Optional) Enable syntax-check to check the syntax
when this parameter is entered.
Note Though visible in the command-line help string,
the encrypt, status url, and inventory keywords
are not supported.
Step 15 end Return to privileged EXEC mode.
Step 16 show cns config connections Verify information about the configuration agent.
Step 17 show running-config Verify your entries.
