Chapter 5 Configuring Cisco IOS CNS Agents
Configuring Cisco IOS Agents
Enabling the Cisco IOS CNS Agent
After enabling the CNS event agent, start the Cisco IOS CNS agent on the switch. You can enable the
Cisco IOS agent with these commands:
The cns config initial global configuration command enables the Cisco IOS agent and initiates an
initial configuration on the switch.
The cns config partial global configuration command enables the Cisco IOS agent and initiates a
partial configuration on the switch. You can then use the Configuration Engine to remotely send
incremental configurations to the switch.

Enabling an Initial Configuration

Beginning in privileged EXEC mode, follow these steps to enable the CNS configuration agent and
initiate an initial configuration on the switch:
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 cns config connect-intf interface-prefix
[ping-interval seconds] [retries num]
Enter the connect-interface-config submode, and specify
the interface for connecting to the Configuration Engine.
Enter the interface-prefix for the connecting interface.
You must specify the interface type but need not
specify the interface number.
(Optional) For ping-interval seconds, enter the
interval between successive ping attempts. The range
is 1 to 30 seconds. The default is 10 seconds.
(Optional) For retries num, enter the number of ping
retries. The range is 1 to 30. The default is 5.
Step 3 config-cli
or
line-cli
Enter config-cli to connect to the Configuration Engine
through the interface defined in cns config connect-intf.
Enter line-cli to connect to the Configuration Engine
through modem dialup lines.
Note The config-cli interface configuration command
accepts the special character & that acts as a
placeholder for the interface name. When the
configuration is applied, the & is replaced with the
interface name. For example, to connect through
FastEthernet0/1, the command config-cli ip
route 0.0.0.0 0.0.0.0 & generates the command
ip route 0.0.0.0 0.0.0.0 FastEthernet0/1.
Step 4 exit Return to global configuration mode.
Step 5 hostname name Enter the hostname for the switch.
Step 6 ip route network-number Establish a static route to the Configuration Engine whose
IP address is network-number.
