To view information about your IP address allocations, click the IP Addresses tab. You see a list of the public IP addresses allocated to your account.
Your virtual machines reside behind a virtual router. Subsequently this IP address could be that of your virtual router, and not of a particular virtual machine (which in turn could have a private IP address). You can see the following information in the Details section.
- ID: The unique ID for this IP address, assigned by your service provider.
- Account: The account to which the IP is assigned.
- Zone: The zone in which this IP address resides.
- VLAN: Information about the virtual local area network.
- Source NAT: Whether Network Address Translation is enabled on this virtual router.
- Network ID: The unique ID provided by your service provider.
- Associated Network ID: Associated network ID provided.
- Domain: The domain associated with the account.
- Allocated: The date and time at which this IP address was allocated.
- Static NAT: Is the NAT static or dynamic? (Request an additional IP address for your virtual router if static NAT is Yes.)
Acquiring an IP address
To acquire a new IP address, click Acquire IP. Specify if it is for a VPC or network, select the network or VPC, select the check box for terms and conditions, and click Confirm.
Firewall rules defined. You can add more firewall rules.
Public Port: The port range that you would like to use.
Private Port: The corresponding private port range.
Protocol: The network protocol applicable. TCP, UDP, and so on.
Virtual Machine: The virtual machine to which to forward the port range.
Name: A name for this Load Balancer rule.
Public Port: The externally accessible port that you would like to balance.
Private Port: The corresponding private port on a VM.
Algorithm: The process by which this balance will occur. Choose from the drop-down options.
If your VPN is already enabled, you see the message below telling you so.
Select the IP address. Move the cursor over the gear wheel icon. You see a list of actions that you can perform for the selected IP address.
Enabling or Disabling Static NAT: A static NAT rule maps a public IP address to the private IP address of a VM to allow Internet traffic to it. You can enable or disable static NAT for a particular IP address in a VPC. Click Enable Static NAT. Select the network and the VM and click OK. To disable Static NAT, click Disable Static NAT and then, click Confirm.
Releasing an IP: If you no longer need a particular IP, you can disassociate it from its VPC and return it to the pool of available addresses. Click Release IP and then, click Confirm.
The health check is used to
- Ensure that the backend services are healthy.
- Ensure the load balancing rule does not send any further requests to an unhealthy backend service(s).
Benefit of configuring Health Checks on LB Rule:
With the ability to perform health checks on the right set of parameters, the load balancer can service all of the requests by forwarding requests to healthy VMs in case of a VM failure . Based on the health check configured, load balancer will know that the service is unavailable since the VM is unavailable.
Note: This feature is supported from CloudPlatform 4.1.x onwards for load balancer created through NetScaler.
Load Balancer tab
You can configure health check on a LB rule in this tab. After the health checks are configured the load balancer can automatically remove a VM from load balancer pool, if the health checks fail. Similarly, if the health checks are successful, the load balancer can add the VMs back to the pool. The following are the configuration details for a health check policy:
- Ping Path: Load Balancing sends health check queries to the path you specify in Ping Path.
- Description: A short description of the policy.
- Response Timeout (in sec): Time to wait when receiving a response from the health check (2sec - 60 sec), Default value is 5 sec.
- Health Check Interval (in sec): Amount of time between health checks (0.1 min - 5min). Default value is 5 sec.
- Healthy Threshold: Number of consecutive health check success before declaring an instance healthy. Default value is 2.
- Unhealthy Threshold: Number of consecutive health check failures before declaring an instance unhealthy. Default value is 10.
Configuring Health Check policy: When you configure the health check policy for the first time, select the LB rule. Move the cursor over the gear wheel icon. Click the Manage Health Policyoption. Specify the required details and click Create.
Editing Health Check policy: Subsequently, click Edit to modify the details entered.
Deleting Health Check policy: Click Delete to delete an existing health check policy.
Searching and filtering IP addresses
The IP Addresses tab lists all IP addresses. As a master user/power user/normal user, you can find a particular IP address/IP addresses by using the search and filter options. The option to search and filter is visible in the CPBM UI only if the CloudPlatform Connector version supports search and filter operations for IP addresses.
- Log in to CloudPortal Business Manager UI as master user/power user/normal user.
- Either click My Services and then click the desired CloudPlatform service instance tab or click Manage Resources and then click the desired CloudPlatform service instance link.
- Click the IP Addresses tab.
- In the Search box, specify the IP address and click Enter.
- To filter the list of IP addresses:
- Click the Filter icon.
- Select the filter option zone and select the desired filter parameter from the dropdown list.
- Click Go!.
