Chapter 6 Configuring IE2100 CNS Agents
Configuring CNS Embedded Agents
To disable the CNS configuration 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 host name
is the unique ID. The CNS Configuration Registrar 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
Step 8
cns config initial {ip-address | hostname} [port-number]
[event] [no-persist] [page page] [source ip-address]
[syntax-check]
Enable the configuration agent, and initiate an initial
configuration.
• For {ip-address | hostname}, enter the
IP address or the host name 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 keyword is not supported.
