> # Merge Guidelines for RADIUS and TACACS+ Configurations

> The RADIUS and TACACS+ server and global configuration are merged when two fabrics merge. The merged configuration is applied to CFS distribution-enabled switches.

> When merging the fabric, be aware of the following conditions:

> - The server groups are not merged.
> - The server and global keys are not changed during the merge.
> - The merged configuration contains all servers found on all CFS enabled switches.
> - The timeout and retransmit parameters of the merged configuration are the largest values found per server and global configuration.

> Note Test parameter will be distributed via CFS for TACACS+ Daemon only. If the fabric contains only Cisco NX-OS Release 5.0 devices, then the test parameters will be distributed. If the fabric contains devices running Release 5.0 and some running Release 4.x, the test parameters are not distributed.

> Caution | If there is a conflict between two switches in the server ports configured, the merge fails.
