Setting the EAD rule timer
EAD fast deployment automatically creates an ACL rule, or an EAD rule, to open access to the redirect
URL for each redirected user seeking to access the network. The EAD rule timer sets the lifetime of each
ACL rule. When the timer expires or the user passes authentication, the rule is removed. If users fail to
download EAD client or fail to pass authentication before the timer expires, they must reconnect to the
network to access the free IP.
To prevent ACL rule resources from being used up, shorten the timer when the amount of EAD users is
large.
