View or modify details for
each IP group and IP addresses within the IP group.
Before you begin
You must be assigned one of the following permissions to
perform these steps:
- Cloud group administration role with permission to View all cloud groups (Read-only)
- Cloud group administration role with permission to View all cloud groups (Read-only permission)
- Resource level administration role with Read access rights permission (ACL) to view a specific instance
- Resource level administration role with Write or All access rights permission (ACL) to view and manage a specific instance
For an overview of IP groups and how they are used with Cloud Pak System Software, see IP groups overview.
About this task
You can use the console, the command line interface, or the REST API to complete this task. For the command line and REST API information, see the Related information section.
Procedure
- Click .
If you are on 2.3.3.3, navigate to .
- Select an IP group.
You can view
or modify the following fields.
Editable
fields display either edit or remove links, or are underlined with
a dash line.
- Jobs
- Specifies the jobs associated with the IP group.
- Description
- Specifies the description of the IP group.
- State
- Specifies the state of the IP group.
- Created on
- Specifies the date that the IP group was created.
- Updated on
- Specifies the date that the IP group was last updated.
- Version
- Displays IPv4 or IPv6 as
the version of the IP addresses specified when the IP group is added.
Important: Workloads that require IP caching must be deployed
to cloud groups with only IPv4 IP groups.
- Used For
- The IP group uses Data for user access
to virtual machines.
- Subnet address
- Enter a valid subnet address. This subnet address is associated
with the IP group represented as a string in dotted decimal notation,
for example: 192.168.98.0.
- Network address
- This address is associated with the IP group represented as a
string in dotted decimal notation, for example: 192.168.98.0 for IPv4
or 2001:218:420::/64 for IPv6.
- Netmask
Important: This field applies only to IPv4.
This
network mask is associated with the network address of the IP group
that is represented as a string in dotted decimal notation, for example:
255.255.255.0.- Gateway
- Specifies the gateway address for the IP addresses in the IP group.
This information is required when you are creating an IP group.
- Primary DNS
- Specifies the primary Domain Name System (DNS) value for the IP
group. This DNS server is used for the IP group represented as a string
in dotted decimal notation, for example: 192.168.98.2.
When
you modify the Primary DNS value, new virtual
machine deployment will use the new value. However, you must manually
update the DNS value for any virtual machines that are already deployed.
Important: If the IP addresses for the DNS servers are not set
up correctly, the deployment can fail. The failure is caused by a
failed connection between Secure Shell (SSH) and the virtual machine.
- Secondary DNS
- Specifies an additional optional secondary DNS value for the IP
group. This secondary DNS server is used for the IP group represented
as a string in dotted decimal notation, for example: 192.168.98.2.
When you modify the Secondary DNS value,
new virtual machine deployment will use the new value. However, you
must manually update the DNS value for any virtual machines that are
already deployed.
- VLAN
- Specifies the virtual local area network.
- In cloud group
- Specifies the cloud group for which the IP group is associated.
The system includes three default cloud groups or
you can create your own. You can select a cloud group from this drop
down menu. You can leave this field blank if you have not created
your cloud group yet. After you create the cloud group, edit this
field with the new cloud group.
- IP addresses
- Provides a numerically sorted list of IP addresses that have been
added to the IP group. Choose from the following actions:
- Remove
- Indicates any IP groups that are inactive and can be removed.
- Add by
- Use the two entry boxes and the Add link
to add strings of IP addresses at a time. Entering the first IP address
in the string in the first box and the final IP address in the second
box adds all IP addresses, numerically, between the two addresses
specified.
- You can add IP addresses as host names instead of the actual IP
addresses. Select Host names in the Add
by menu. When a host name is specified for an IP address,
the host name resolves to the IP address. However, what is entered
is what is stored. Therefore, if you enter the host name then the
host name is stored and not the IP address to which it resolves. If
any of the host names entered cannot be resolved to IP addresses,
then a warning message is shown beside any entry that cannot be resolved.
If a host name is resolved to an IP address but the IP address is
not valid for the specified subnet, then an error message is shown
and the host name is not added to the IP group.
- Routes
- Provides a list of IP routes that have been added to the IP group.
Choose from the following actions to add or remove
IP routes:
- Remove
- Add
For an IP group with a
Used
for setting of
Cloud management,
you must define the following:
- a subnet route via this IP group's gateway address to the system
management subnet configured on the System > Network Configuration configuration
page.
- a subnet route via this IP group's gateway address to any other
management IP group subnet that your deployments will span. For example,
in a multisystem deployment, the cloud management IP groups on each
system require a subnet route to each other.
Additional route configuration is optional for IP groups with
a
Used for setting of
Data.
You can configure routes for data IP groups as a way of providing
special routing for your virtual machines' add-on NICs.
- Access granted to
Select user IDs from the Add more menu
for those users who require access to the IP group.
To view
the users with admin access, click admin. To
display all users, click all. To remove a user,
click remove.
