Document URL: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/installation_guide/chap-anaconda-boot-options Section Number and Name: Table 22.5. Automatic Interface Configuration Methods Describe the issue: "The netmask parameter is the netmask to be used. This can either be a full netmask (for example 255.255.255.0) or a prefix (for example 64)." Suggestions for improvement: This is not a valid statement. Probably for IPv4 this works, but I have just verified that Anaconda errors out if netmask is provided using full syntax [ffff:ffff::] and only accepts prefix. Additional information: Did not capture screenshot of the error, but Anaconda stops and wont boot up.
I fixed the issue and it is available at: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/installation_guide/chap-anaconda-boot-options#sect-boot-options-installer
