Description
This article describes how to add a Node on the Network Domain as a new Pool Member to a Pool.
Prerequisites:
- Only the Primary Administrator or a User with the Network role can add a Pool on a Network Domain.
- Data Center must be MCP 2.0
- Recommended reading: Introduction to Virtual Listeners / VIPs in MCP 2.0
- Must have at least one Advanced Network Domain deployed. See How to Deploy a Network Domain in a MCP 2.0 Data Center Location
- This feature is not supported on Essentials Network Domains.
- Must have created at least one Pool. See How to Add a Pool on a Network Domain
- You must have at least one node on the Network Domain created either:
- explicitly: How to Create a Node on a Cloud Network Domain
- implicitly via NAT Rule creation: How to Create a NAT Rule on a Network or Network Domain
Content / Solution:
From the Home page, select the MCP 2.0 Data Center where the Advanced Network Domain on which the Pool to which you want to add a Node as a Pool Member is located:
The Data Center dashboard will be displayed. Select the Advanced Network Domain on which the Pool to which you want to add a Node as a Pool Member:
The Network Domain dashboard will be displayed. Click on the Load Balancing / Virtual IPs tab. Locate the Pool on to which you want to add a Node as a Pool Member, and click on the Manage gear:
Add a New Node as a Pool Member
Select 'Add new Nodes to Pool' from the dropdown menu:
The Create Nodes dialog will be displayed:
Fill out the Create Nodes form with the requested information:
- IP Version - Both IPv4 and IPv6 are supported
- The acceptable range of IPv4 addresses for a Node are: X.X.X.6, and X.X.X.8 - X.X.X.254. This applies to a private IP address being specified that falls within an existing VLAN. Otherwise there's no restriction.
- Note: You cannot create a Node on a Private IPv4 Address already in use by a Virtual Listener on the same Network Domain.
- Node Name - Enter a descriptive Name for the Node. This name should be unique across the Network Domain.
- Must begin with a letter
- May not include spaces
- Permitted special characters are "_" and "."
- Node Destination IP Address - IP Address can not already be in use on another Node within the Network Domain. IPv4 addresses must be within the permitted standard range (.6, .11-.254).
- Description - The optional Description is limited to a maximum length of 255 characters.
- Connection Limit - The maximum number of simultaneous connections permitted on the Node. Should be an integer between 1 and 100,000. The system default is set to 100,000.
- Connection Rate Limit - The amount of new connections permitted every second. Should be an integer between 1 and 4,000. The system default is set to 4000.
- Node Status - Describes what action the Node will take.
- "Enabled" - Permits traffic.
- "Disabled" - A Node continues to process persistent and active connections. It can accept new connections only if the connections belong to an existing persistence session.
- "Forced Offline" - A Node allows existing connections to time out, but no new connections are allowed.
- Node Health Monitor - The procedure that the load balancer uses to verify that the Node is considered “healthy” and available for load balancing.
- "CCDEFAULT.Icmp" - Sends an ICMP ECHO request to the Node and considers the Node healthy if an ICMP ECHO reply is received.
- Note: A Health Monitor is not required. You can select 'None' from the drop down menu.
- Pool Member Settings - Specific settings dealing with a Node added as a Pool Member.
- Port - Enter the Port you would like the Pool Member to be associated with.
- Pool Member Status - Select an initial Status for the Pool Member from the dropdown menu.
- Enabled - Permits traffic.
- Disabled - Continues to process persistent and active connections. It can accept new connections only if the connections belong to an existing persistence session.
- Forced Offline - Allows existing connections to time out, but no new connections are allowed.
Once the form is complete, click the Create Nodes button:
IMPORTANT NOTES:- You cannot add a member Node to a Pool twice using the same port.
- "Any port" is only a valid option if Health Monitors are not present on the Pool.
- If Health Monitors are present on the Pool, a port must be specified for each Pool Member.
- You cannot have members in the same Pool that have "Any" and a "specific" port.
- You cannot add a Node with a specific port to a pool, and then add it again to the same pool with ANY port.
- You can optionally select up to 100 Nodes for the Pool (members as a Node can be added more than once).
The system will display a success message:
The new Node will be created and added to the Pool as a Pool Member. The UI will be updated to reflect the change:
Add an Existing Node as a Pool Member
Select 'Add Existing Nodes to Pool' from the dropdown menu:
The Add Existing Nodes to Pool dialog will be displayed:
Fill out the form with the desired information:
Node Name - Select the existing Node from the dropdown menu.
Port - Enter the Port you would like the Pool Member to be associated with.
- Pool Member Status - Select an initial Status for the Pool Member from the dropdown menu.
- Enabled - Permits traffic.
- Disabled - Continues to process persistent and active connections. It can accept new connections only if the connections belong to an existing persistence session.
- Forced Offline - Allows existing connections to time out, but no new connections are allowed.
Once the form has been filled out, click the Add Nodes button:
IMPORTANT NOTES:- You cannot add a member Node to a Pool twice using the same port.

The Node will be added to the Pool as a Pool Member and the UI will be updated to reflect the change:
