interval: Interval at which Accounting-On packets are sent, ranging from 1 to 30 and
defaulting to 3 seconds.
Description
Use the accounting-on enable command to enable the user re-authentication upon
device restart.
Use the undo accounting-on enable command to disable the user re-authentication
upon device restart and restore the default interval and maximum number of attempts
to transmit Accounting-On packets.
Use the undo accounting-on send command to restore the default maximum number
of attempts to transmit Accounting-On packets.
Use the undo accounting-on interval command to restore the default interval to
transmit Accounting-On packets.
By default, this function is disabled.
The purpose of this function is to resolve this problem: users cannot re-log into the
switch after the switch restarts. After this function is enabled, every time the switch
restarts:
z The switch generates an Accounting-On packet, which mainly contains the
following information: NAS-ID, NAS-IP address (source IP address), and session
ID.
z The switch sends the Accounting-On packet to CAMS at regular intervals.
z Once the CAMS receives the Accounting-On packet, it sends a response to the
switch. At the same time, it finds and deletes the original online information of the
users who accessed the network through the switch before the restart according to
the information contained in this packet (NAS-ID, NAS-IP address and session ID),
and ends the accounting of the users based on the last accounting update packet.
z Once the switch receives the response from the CAMS, it stops sending other
Accounting-On packets.
z If the switch does not receive any response from the CAMS after the times it
transmit Accounting-On packet reaches the configured maximum times, it stops
sending any more Accounting-On packets.
