set interfaces ge-0/0/0 unit 0 family inet address 1.1.2.31/24

The command will assign 1.1.2.31/24 to interface ge-0/0/0

The keyword "family" has to be created first on address book?

Or the command itself will automatically  create "family" on address book with the IP Address of 1.1.2.31/24?

Please help. Thanks.

Hello,

family is the keyword. It is not an address. You can configure family inet(ipv4), inet6(ipv6), ethernet-switching etc. as a family for the interface.

So there is no need to create address book entry named family.

Hi Rushi, please let me know if I understand wrongly.

So when creating an interface the keyword "family" has to be specified?

I was thinking that the keyword "family" can be change to something else like "email_interface_family", something like that.

Basically the keyword "family" is part of the command syntax?

Thanks.

Hello,

Keyword family has to be specified followed by whichever protocol family you want to configure on the interface.

After this keyword, you will get multiple options like inet for ipv4, inet6 for ipv6, ethernet-switching for L2 config etc.

Below is the output from my lab firewall:

root# set interfaces ge-0/0/1.0 family ?
