Managing Resource Pools

Cisco VTS enables you to define global and device local resource pools so that the resources can be allocated when VMs or tenants are added.

You can define the multicast addresses that can be allocated sequentially for VXLAN tunnel creation so that you do not have to manage them separately. VNI and multicast pools are global and VLAN pool is for each device. You can define the multicast addresses as global resource pool. These multicast addresses will be allocated sequentially when new VXLAN tunnels are created. Network administrator can define multiple multicast address ranges.


Note

Default resource pools are device-specific VLAN pools that are also created automatically when leafs are added to the inventory. The default VLAN range is from 1001 to 2000. You can modify the range as per your requirement.

You can also specify global VNI pool range and device-specific VLAN pool range.

You can edit the range and also delete any unused ranges.

This chapter has the following sections:

Specifying Global VNI Pool Range

You can specify the global VNI pool range. To do this:

    Step 1   Go to Resource Pools > Global VNI Pool. The Resource Pools / Global VNI Pool window appears.
    Step 2   Click the Add (+) icon. Specify the ranges, and click Save.

    To edit the range, select the Range From check box, and click the Edit icon as required.

    To delete the range, select the Range From check box, and click the Delete (X) icon.

    Specifying VLAN Pool Range

    VLAN pool needs to be created for all the leafs and DCIs. You can create device specific VLAN pools. You can also group devices together, and create a VLAN pool for the group.


    Note

    We recommend that you check the supported VLAN pool range for the device that is created automatically, and also take a note of the reserved VLAN range. Every device has its own limitation. You need to ensure that you are not using a reserved VLAN range for your particular device.

    See the following sections for details:

    Specifying Device VLAN Pool Range

    To specify device VLAN pool:

      Step 1   Go to Resource Pools > VLAN Pool. The Resource Pools / VLAN Pool window appears.
      Step 2   Click Devices.
      Step 3   Click the Add (+) icon. The Add Range pop up window appears.
      Step 4   Enter the Device details, and specify the From and To values.

      The device name should match the leaf name in the inventory. From is VLAN start number and To is VLAN end number to be used for the leaf.

      Step 5   Click Save.

      To edit a device specific VLAN pool, select the Device check box, and click the Edit icon.

      To delete a device specific VLAN pool, select the Device check box, and click the Delete (X) icon.

      Specifying Group VLAN Pool Range

      To specify VLAN pool range for a device group:

        Step 1   Go to Resource Pools > VLAN Pool. The Resource Pools / VLAN Pool window appears.
        Step 2   Click Groups
        Step 3   Click the Add (+) icon. The Add Group pop up window appears.
        Step 4   Enter the Group Name and select the devices that need to be part of the group. Click the help icon for guidelines about the group name.

        To view the devices associated with a group, select the group and click Associated Devices.

        Step 5   Click Save. The group gets created and is listed in the table.
        Step 6   To add range to the group, select the group and click the Add (+) icon.
        Step 7   Specify the From and To values.
        Step 8   Click Save.

        To delete a group specific VLAN pool, select the Device check box, and click the Delete (X) icon.

        Specifying Multicast IP Pool

        You can specify the IP range. The range must be within the multicast IP address range configured on leaf devices via day zero configuration file. The only valid IPv4 address starting with 0 is 239.0.0.0/8.
          Step 1   Go to Resource Pools > Multicast IP Pool. The Resource Pools / Multicast IP Pool window appears.
          Step 2   Click the Add (+) icon, and enter the Netmask values.

          Click the Question Mark (?) icon to view the Multicast IP address range.

          Step 3   Click Save.

          To delete Multicast IP Pool, select the Netmask check box, and click the Delete (X) icon.
