Chapter 4 Configuring Cisco IOS CNS Agents
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 cancel privileged EXEC
command.
Step 10
show cns config connections Verify information about the configuration agent.
Step 11
show running-config Verify your entries.
Command Purpose
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
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.
Step 3
end Return to privileged EXEC mode.
Step 4
show cns config stats
or
show cns config outstanding
Verify information about the configuration agent.
Step 5
show running-config Verify your entries.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
