Common elements for node tasks
Local traffic pools use nodes as resources for load
balancing. Nodes represent the actual server resources that host the applications.
- On the Main tab, click.The Node List screen opens.
- On the Main tab, expandLocal Traffic, and clickNodes.The Node List screen opens.
- In the Name column, click a node name.
- In the Name column, click a node name.This displays the properties of the node.
- In the Name column, locate the node you want to enable.
- In the Name column, locate the node you want to disable.
- Click theEnablebutton.
- Click theDisablebutton.
- Select the check box to the left of the node name.
- For theStateproperty, clickForced Offline (Only active connections allowed).
- Click theCreatebutton.The New Node screen opens.
- In theAddressfield, type the IP address of the alert server.
- In theAddressfield, type the IP address of the web application server.
- In theAddressfield, selectAddressand type the IP address of the node.
- For theAddresssetting, select eitherAddressorFQDN, and then type either the IP address or the fully-qualified domain name of the node.
- Configure all other settings as needed or retain the default values.
- In the Configuration area of the screen, configure the settings as needed or retain the default values.
- For theAddresssetting, selectFQDN, and then type the host name in the field.
- For theAddresssetting, selectFQDN, and then type the host name in the field.
- In theNamefield, type a descriptive label for the node.Names are case-sensitive.
- In the Configuration area, from theHealth Monitorslist, select the way that you want the system to apply monitors to the node.The default setting isNode Default.Node DefaultSpecifies that the system uses the defined default monitors for nodes. The default monitors are defined on the Default Monitors screen of the BIG-IP Configuration utility.Node SpecificSpecifies that the system monitors this node with the monitors that you configure in theSelect Monitorssetting.When you select theNode Specificoption, the screen refreshes to display theSelect Monitorssetting.NoneSpecifies that the system does not monitor this node.
- You can move and add monitors to the appropriate list as needed.ActiveSpecifies the health monitors that the system currently uses to monitor this node.AvailableSpecifies the health monitors that are configured on the system, and that you can use to monitor this node.
- If you activate more than one health monitor (in theSelect Monitorssetting), specify the number of health monitors that must receive successful responses in order for the node to be considered available. The default isAll.
- In theRatiofield, type a number for the ratio weight of the node.
- In theConnection Limitfield, type a number for the maximum established connection limit for the node.
- In theConnection Rate Limitfield, type a number that specifies the number of new connections accepted per second for the node.
- If you specified an IP address in theAddresssetting, clickFinished. If you specified an FQDN, configure the remaining settings.
- From theAddress Typelist, select whether the node resolves to an IPv4 or IPv6 address. The default isIPv4.
- From theAddress Typelist, select whether the node resolves to an IPv4 or IPv6 address. The default isIPv4.
- From theAuto Populatelist, selectEnabled. The options are:EnabledThe system automatically creates ephemeral nodes using the IP addresses returned by the resolution of a DNS query for the FQDN, that is, for each DNS entry of the resolved FQDN.DisabledThe system automatically creates a node that corresponds to the IP address of only the first DNS entry of the resolved FQDN.
- In theIntervalfield, type the number of seconds before the system creates new ephemeral nodes or deletes expired ephemeral nodes based on the IP addresses returned in response to a DNS query for the FQDN of the node. The default is the TTL of the IP address in the DNS response.
- In theDown Intervalfield, type the number of seconds the system waits to mark an FQDN node down following a DNS query failure.
- In the State area, clickDisabled (Only persistent or active connections allowed).You can only disable the parent FQDN node or pool member. After disabling, the ephemeral dependents are then disabled, but you cannot directly disable an ephemeral node.
- For theAddressfield:
- If you want to specify the node by its IP address, clickNodesand type an IP address.
- If you want to specify the node by a fully-qualifed domain name (FQDN), clickFQDNand type the node's FQDN.
- If you choseFQDNfor theAddresssetting, then in the FQDN area of the screen, configure the settings as needed or retain the default values.
- ClickUpdate.The screen refreshes, and the status in the Availability area changes.
- At the bottom of the screen, clickUpdate.
- ClickCancel.
- ClickFinished.The screen refreshes, and the new node appears in the node list.
- Locate theStateproperty and view the selected value.
