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
Step1 configure terminal Enter global configuration mode.
Step2 cns template connect name Enter CNS template connect configuration mode, and specify the
name of the CNS connect template.
Step3 cli config-text Enter a command line for the CNS connect template. Repeat this
step for each command line in the template.
Step4 Repeat Steps 2 to 3 to configure another CNS connect template.
Step5 exit Return to global configuration mode.
Step6 cns connect name [retries number]
[retry-interval seconds] [sleep seconds]
[timeout seconds]
Enter CNS connect configuration mode, specify the name of the
CNS connect profile, and define the profile parameters. The
switch uses the CNS connect profile to connect to the
Configuration Engine.
Enter the name of the CNS connect profile.
(Optional) For retries number, enter the number of
connection retries. The range is 1 to 30. The default is 3.
(Optional) For retry-interval seconds, enter the interval
between successive connection attempts to the Configuration
Engine. The range is 1 to 40 seconds. The default is
10 seconds.
(Optional) For sleep seconds, enter the amount of time
before which the first connection attempt occurs. The range
is 0 to 250 seconds. The default is0.
(Optional) For timeout seconds, enter the amount of time
after which the connection attempts end. The range is 10 to
2000 seconds. The default is120.
