Adding a VLAN Interface to a Node (CTP Menu)

This topic describes how add a VLAN interface to a node. Adding VLAN interfaces to a node comprises two steps:

Adding a VLAN ID to the System

When you add a VLAN to a node, the network and CTP devices are restarted to update the network parameters. The node is not restarted.

Note: For VLAN switchover to function correctly, VLANs must be configured on the primary Ethernet interface (for example, eth1) that has IPv4 configured and Ethernet switchover enabled.

To add a VLAN ID to the system from the CTP Menu:

  1. From the Main Menu, select 5) Node Operations > 3) Configure network settings > 8) VLAN Configuration.

    Field

    Function

    Your Action

    How do you want to change VLANs ?

    Enter add to add a new VLAN, delete to remove a VLAN, and rtn to show existing VLANs.

    Enter add to create a new VLAN.

    Which ethernet port the new VLAN will be added on ?

    Specify the ethernet port number. The default value is 0 (zero).

    What is the new VLAN id ?

    Assign the VLAN ID for the newly created VLAN in the range 0–4095. The default value is 0 (zero).

Configuring VLAN Interface by Using the VLAN ID

  1. From the Main Menu, select 5) Node Operations > 3) Configure network settings > 2) IPv4 Configuration to assign an IP address for the VLAN.

    There are 2 ethernet devices available for use. The default device
    is the device through which the default gateway can be accessed.
    Ctp circuits can run over any ethernet device, default or not.
    A default device must be configured, other devices may be configured
    and enabled, or disabled. Here is a list ot the available devices
    and their descriptions:

    eth0: 10/100/1000 Copper (right back)
    eth1: 10/100/1000 Copper (left back)
    List of VLAN interface :
    eth1.111: Vlan ID 111 on ehternet port 1
    What device would you like to make the IPV4 default device? (rtn for eth1):
    OK, eth1 (10/100/1000 Copper (left back)) will be configured as IPV4 default
    device.
    Please input the hostname (return for ctp_90):
    ===== Configuration for eth0:
    Activate IPV4 interface eth0 on boot [n]
    ===== Configuration for eth1 (default device):
    Please input the ip (return for 10.216.118.90):
    Please input the netmask (return for 255.255.254.0):
    Please input the gateway (return for 10.216.119.254):
    Please input the mtu in bytes (return for 1500):
    Add route to interface eth1 [n]
    IPV4 configuration for VLAN interfaces :
    ===== Configuration for eth1.111:
    Activate IPV4 interface eth1.111 on boot [n] y
    Please input the ip (return for 10.0.0.1): 1.1.1.1
    Please input the netmask (return for 255.255.255.0):
    Please input the mtu in bytes (return for 1500):
    Add route to interface eth1.111 [n]
    
  2. Follow the onscreen instructions and configure the options as described in Table 5.

    Field

    Your Action

    What device would you like to make the IPv4 default device ?

    Please input the hostname.

    Specify the host name. Press Enter to select the default hostname.

    Activate the IPv4 interface eth0 on boot.

    Enter n.

    Ethernet failover may not work correctly if multiple Ethernet interfaces are activated or the active Ethernet interface is configured as the secondary interface.

    Configuration for eth1 (default device)

    Enter the IP address, network mask, gateway, and MTU for eth1.

    Activate the IPv4 interface eth1.111 on boot.

    Enter y.

    Configuration for eth1.111
