– PAC TTL—The duration that a PAC is used before it expires and must
be replaced. If the master key used to generate it has not expired, new
PAC creation and assignment are automatic. If the master key used to
generate it has expired, in-band or out-of-band provisioning must be used
to provide the end-user client with a new PAC. The default PAC TTL is
one week.
For more information about PACs, see About PACs, page 10-17 .
– Client initial display message—Specifies a message to be sent to users

Note A user will see the initial display message only if the end-user client
supports its display.
– Authority ID Info—A short description of this Cisco Secure ACS, sent
along with PACs issued by Cisco Secure ACS. EAP-FAST end-user
clients use it to describe the AAA server that issued the PAC. Maximum
length is 64 characters.
