Description Lukas Zapletal 2019-07-17 16:33:46 UTC

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.
