Task 1 Solution: Updating DHCP ranges EA

Ranges and Fixed addresses are both child objects of Network. Check for parent objects of ranges and

  1. Login to NIOS GM web interface.

  2. Navigate to Data ManagementDHCPNetworks.

  3. In the Go to field, enter 10.100.0, the system will automatically attempt to auto-complete the entry.

Task 2 Solution: Updating DHCP fixed-addresses EA

The same method can be used to find the Fixed Address objects and edit them as well. This may be tricky because these fixed addresses belong to different parent networks. However, since they share common octets and belong to the data type Fixed Address, we can use Global Search to find them

  1. Login to NIOS GM web interface

  2. Navigate to Global SearchAdvanced

  3. Change search filter to Type equals IPv4 Fixed Address

  4. Provide search string 172.31.*.* and click Search
