Chapter4 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
Step14 cns config initial {hostname | ip-address}
[port-number] [event] [no-persist] [page page]
[sourceip-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.
Step15 end Return to privileged EXEC mode.
Step16 show cns config connections Verify information about the configuration agent.
Step17 show running-config Verify your entries.
