Configuring the Control Plane Switch

You can use the Cisco 2950, 3550, or 4503 switch to provide connectivity for the control plane of the N1 Provisioning Server software. In a typical scenario, the management port of the control plane server and the management port of the chassis switches are connected to this switch.

Refer to the Cisco documentation for login procedures and commands.

The management VLAN configured on this switch should be vlan 9. Log onto the control plane switch, and type the following commands to create VLAN 9.

enable
vlan database
 vlan 9 name ManageMentVlan state active media ethernet
 exit

Although the control plane server does not require the control plane switch to have IP connectivity on the management VLAN, you can optionally configure a management IP address on this switch. Type the following commands to create a management IP on this switch:

enable
configure terminal
interface Vlan1
 no ip address
 shutdown
 exit
interface Vlan9
 ip address <IP_address> <IP_subnet_mask>
 no shutdown
 end

Because the VLAN 9 interface is configured with an IP address, you also need to move the uplink to the external router to VLAN 9. To move the uplink, type the following commands:

configure terminal
interface FastEthernet 0/<port>
switchport access vlan 9
speed 100
duplex full
end

To set the default gateway on the device, type the following command :

configure terminal
ip default-gateway <IP_of_default_gateway>
end

To enable a telnet connection to the switch, type the following commands:

configure terminal
line vty 0 4
 password <PASSWORD>
 login
line vty 5 15
 password <PASSWORD>
 login
 exit

To set the enable password for the switch, type the following commands:

configure terminal
enable password 0 <password>
end

To move a port to a particular VLAN, do the following steps:

1. Use telnet or console to connect to the switch.

2. Enter enable and configure mode and type the following commands.

   interface <IF_NAME> switchport access vlan <VLAN_ID> speed 100 duplex full end

You must move all chassis NETMGT and control connections from the control plane and image server to VLAN 9.

The following example shows a management port of a chassis switch that is connected to FastEthernet0/24 being moved to vlan 9.

configure terminal
interface FastEthernet0/24
 switchport access vlan 9
 end

When you are done, type write mem to permanently save all the configurations.

To view the switch configuration type show configuration. The following example shows an example of the output of the show configuration command.
