> # Remote AAA Services

> Remote AAA services provided through RADIUS and TACACS+ protocols have the following advantages over local AAA services:

> - User password lists for each switch in the fabric can be managed more easily.
> - AAA servers are already deployed widely across enterprises and can be easily adopted.
> - The accounting log for all switches in the fabric can be centrally managed.
> - User role mapping for each switch in the fabric can be managed more easily.
