This sets the re-

interval
Result:
This sets the re-authentication interval.
Important!
To judge whether access subscriber maintains
connection all time, NAS can periodically request re-
authentication of this subscriber. Re-authentication needs
to initiate a complete authentication process for each on-line
subscriber. If number of subscribers is large, there will be
a lot of authentication packets, which brings a heavy burden
to the switch.
7. To enable/disable abnormal off-line detection mechanism
of the port, use command
aaa-control port
<portlist>
keepalive {enable|disable}
in nas config mode. This is
shown in Table 263.

Besides re-authentication mechanism, NAS module also
introduces abnormal off-line detection mechanism to
judge whether subscriber still keeps the connection.
