All examples use comma as the separator. You can use other supported separators, such as semicolon, space, or tab. ## Adding an IPv4 Fixed Address This example shows how to import a new IPv4 fixed address. `header-fixedaddress,ip_address*,network_view,mac_address*,match_option,ms_server, remote_id,EA-Sitefixedaddress,100.0.0.1,Default,aa:aa:aa:aa:aa:aa,Remote_ID,xyz,USA` To import MS sync data, specify ms_server field in the CSV format. `header-fixedaddress,ip_address*,ms_Server,EA-Location fixedaddress,100.0.0.1,100.102.30.180,location-1` ## Overwriting IPv4 Fixed Address Data This example shows how to overwrite the MAC address of an existing IPv4 fixed address from aa:aa:aa:aa:aa:aa to bb:aa:aa:aa:aa:aa. `header-fixedaddress,ip_address*,mac_address* FixedAddress,100.0.0.1,bb:aa:aa:aa:aa:aa` This example shows how to overwrite the address of an existing IPv4 fixed address from 100.0.0.1 to 100.0.0.10. `header-fixedaddress,ip_address*,_new_ip_address,mac_address* FixedAddress,100.0.0.1,100.0.0.10,bb:aa:aa:aa:aa:aa` ## Merging IPv4 Fixed Address Data This example shows how to merge a new comment to an existing IPv4 fixed address. `header-fixedaddress,ip_address,mac_address*,comment FixedAddress,100.0.0.10,bb:aa:aa:aa:aa:aa,A new comment here.` This example shows how to merge new routers addresses and the domain name to an existing IPv4 fixed address. `header-fixedaddress,ip_address*,mac_address*,routers,domain_name fixedaddress,100.0.0.10,bb:aa:aa:aa:aa:aa,"2.2.2.2,4.4.4.4",ns1.corp100.com` ## Adding an IPv4 Reservation This example shows how to import a new IPv4 reservation. `header-fixedaddress,ip_address*,network_view,mac_address*,EA-Site fixedaddress,100.0.0.1,Default,00:00:00:00:00:00,USA`
