TACACS+ Authentication
Operating Notes
■ When TACACS+ is not enabled on the switch—or when the switch’s
only designated TACACS+ servers are not accessible— setting a local
Operator password without also setting a local Manager password
does not protect the switch from manager-level access by unautho-
rized persons.
■ When using the copy command to transfer a configuration to a TFTP
server, any optional, server-specific and global encryption keys (page
5-15) in the TACACS configuration will not be included in the trans-
ferred file. Otherwise, a security breach could occur, allowing access
to the TACACS+ username/password information.
