accounting request
Restore the maximum retransmitting times of
stopping accounting request to the default value
By default, the stopping accounting request can be retransmitted up to 500 times.

The RADIUS client (Switch system) and the RADIUS server use MD5 algorithm to
encrypt the exchanged packets. The two ends verify the packet through setting
the encryption key. Only when the keys are identical can both ends accept the
packets from each other and give responses.
You can use the following commands to set the encryption key for RADIUS
packets.
Perform the following configurations in RADIUS Scheme View.
Table 320 Setting the RADIUS Packet Encryption Key
Operation
Set RADIUS authentication/authorization packet
encryption key
Restore the default RADIUS
authentication/authorization packet encryption key.
Set RADIUS accounting packet key
Restore the default RADIUS accounting packet key
By default, the keys of RADIUS authentication/authorization and accounting
packets are all "3com".
Since RADIUS protocol uses UDP packets to carry the data, the communication
process is not reliable. If the RADIUS server has not responded to NAS before
timeout, NAS has to retransmit the RADIUS request packet. If it transmits more
than the specified
retry-times
primary and secondary RADIUS servers has been disconnected.
You can use the following command to set the retransmission times of the RADIUS
request packet.
Perform the following configurations in RADIUS Scheme View.
