Chapter4 Configuring Cisco IOS CNS Agen ts
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. The switch hostname
is the unique ID. The Cisco Configuration Engine IP address is 172 .28.129.22.
Switch(config)# cns config connect-intf serial ping-interval 1 retries 1
Switch(config-cns-conn-if)# config-cli ip address negotiated
Switch(config-cns-conn-if)# config-cli encapsulation ppp
Switch(config-cns-conn-if)# config-cli ip directed-broadcast
Switch(config-cns-conn-if)# config-cli no keepalive
Switch(config-cns-conn-if)# config-cli no shutdown
Switch(config-cns-conn-if)# exit
Switch(config)# hostname RemoteSwitch
RemoteSwitch(config)# ip route 10.1.1.1 255.255.255.255 11.11.11.1
RemoteSwitch(config)# cns id Ethernet 0 ipaddress
RemoteSwitch(config)# cns config initial 10.1.1.1 no-persist
Enabling a Partial Configuration
Beginning in privileged EXEC mode, follow these steps to enable the Cisco IOS agent and to initiate a
partial configuration on the switch:
To disable the Cisco IOS agent, use the no cns config partial {ip-address | hostname} global
configuration command. To cancel a partial configuration, use the cns config can cel privilegedEXEC
command.
Step10 show cns config connections Verify information about the configuration agent.
Step11 show running-config Verify your entries.
Command Purpose
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 cns config partial {ip-address | hostname}
[port-number] [source ip-address]
Enable the configuration agent, and initiate a partial
configuration.
•For {ip-address | hostname}, enter the IP address or
the hostname of the configuration server.
•(Optional) For port-number, enter the port number of
the configuration server. The default port number is 80.
•(Optional) Enter source ip-address to use for the
source IP address.
Note Though visible in the command-line help string,
the encrypt keyword is not supported.
Step3 end Return to privileged EXEC mode.
Step4 show cns config stats
or
show cns config outstanding
Verify information about the configuration agent.
Step5 show running-config Verify your entries.
Step6 copy running-config startup-config (Optional) Save your entries in the configuration file.
