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.
  2. Follow the onscreen instructions and configure the options as described in Table 1.

    Table 1: Configuring a VLAN Interface

    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.
  2. Follow the onscreen instructions and configure the options as described in Table 2.

    Table 2: IP Parameters for Configuring a VLAN

    Field

    Your Action

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

    Select the default Ethernet device.

    Please input the hostname.

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

    Note: Until CTPView Release 7.1R1, when you enter valid fully qualified domain names (FQDN) with subdomains, CTPView does not enable the subdomains (labels or dots) to be entered and has restrictions with the maximum length of the hostname length to be 24 characters. Starting with CTPView Release 7.2R1, you can specify hostnames of CTP devices in compliance with the domain name system (DNS) standards, which enables you to enter labels or subdomains in a hostname. Each label in a hostname can have a maximum of 63 characters and the entire FQDN can be up to a maximum of 253 characters. No specific restriction on the number of labels exists.

    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

    Enter the IP address, network mask, and MTU for eth1.111.
