Sometimes, administrators may accidentally request a device port to be reserved for an IP address when the port is already reserved for another object, or try to apply a different port to an object that already has a port reservation. When these cases arise, Grid Manager reports a conflict.
To resolve port reservation conflicts:

1. Click the link provided in the Conflicts Smart Folder.

2. Expand the Toolbar and click Resolve Conflict, as shown in the figure Locating conflicts and beginning their resolution above.
   The Resolve Port Reservation Conflict dialog opens, showing the differences between the reserved and discovered information.

3. Choose from the following options:

   • Change the reserved port to be the same as the discovered port.

   • Keep the configured port reservation and clear the conflict for the next 1 day(s).

     Note that in the Grid Discovery Properties –> Advanced tab, the Ignore Conflict Duration setting governs the default time duration to ignore (clear) certain types of conflicts that may occur when defining IPAM objects that are associated with discovered and managed devices, interfaces, or IP addresses. Increments can be defined in Hours or Days. For more information, see Defining Seed Routers for Probe Members.

4. Click OK to save changes.

   Note that for other conflict examples, see Resolving Multiple Conflicts below.
   Another category of conflicts involves incorrectly defined device information for the object:

• The reserved Device Type information provided is different from the discovered vendor and device type (Router vs. Switch, for example).

• The defined Device Vendor information does not match with the discovered information.

• A User Port Reservation conflict occurs when an unmanaged IP address attempts to use a port that is already reserved by an IPAM object on a different IP address.
  
  You can choose from the following options:

...

You can define objects for IP addresses, attempt to apply a port reservation, or incorrectly specify a value such as a MAC address or a vendor name, and accidentally cause multiple conflicts after creating the new object.
To resolve multiple conflicts for a particular IP address, use a Resolve Multiple Conflicts wizard:

1. To quickly locate any conflicts, open the Smart Folders panel and open the Conflicts list.

2. Click the IP address for any entry in the Conflicts list. The IPAM page opens for the selected IP address, with the top panel highlighted in pink to indicate the conflict.

3. Open the vertical toolbar and click Resolve Conflict.

4. If multiple issues are involved with the conflict entry, the Resolve Conflicts wizard lists each of them as shown in the below figure.

5. Select the conflict that you want to resolve first and click Next. For example, consider choosing to resolve the MAC Address conflict as shown in above figure. The second step of the wizard appears, listing the differences between the Existing and Discovered information for the conflict as shown in the figure below.

   1. In this case, the MAC address specified in the last fixed address object configuration, for that object, conflicts with the discoveredMACaddress associated with the IP. (You can verify this by checking the RelatedObjects tab in the IPAM page for the IP address.) Choose from one out of two options:

      • Change the configured MAC address to be the same as the discovered MAC address;

      • Keep fixed address and ignore this conflict for the next 1 day(s).
        In this example, the Discovered information for the MAC address associated with the Fixed Address object is one digit off from the Existing MAC information, which was entered incorrectly by the administrator. The DIscovered MAC, shown in red, is the correct value and should be used to overwrite the record for the conflict.

6. Select the Update... with discovered data option and click Resolve.

7.  The wizard updates with a return to the first step, in which you select the next conflict to resolve. A banner shows the result of the first resolution.

8. Select the next conflict to resolve and click Next. As an example, the below figure shows a device configuration conflict.

   1. To resolve the conflict, the Configured information must be overwritten with the Discovered information. Choose any of the following:

      • Change configured device type and vendor to be the same as the discovered device type and vendor

      • Keep current device configuration and clear the conflict for the next 1 day(s)

                Other conflict types have similar options.

10. Select from the above choices and click Resolve.

11. Continue through the wizard to resolve the last conflict associated with the IP address.
